Interior of Neptune’s BAe-146 revealed

The Santa Maria Times ran an article with photos that featured one of Neptune’s BAe-146 air tankers when the aircraft was working out of the Santa Maria Air Attack Base while the White Fire was burning north of Santa Barbara, California. The interesting thing about the article is that it includes a photo of the interior of the BAe-146. It is the first photo I have seen of the interior.

Only the end of the tank is visible, and it is round. You can’t tell if the tank is cylindrical like the MAFFS tanks, or a series of nearly spherical tanks, like in the 747 Supertanker.

We asked the Santa Maria Times for permission to replicate the photo, and they refused, which is of course their right.

 

Thanks go out to John

31,000 gallons in the BAe-146? No

BAe-146 31,000 gallons? no
A screen grab from the NBC Los Angeles TV station video report, exaggerating the capacity of the BAe-146 by over 28,000 gallons.

In a video report Thursday about Tanker 41, “the latest weapon in the firefighting arsenal”, Neptune’s BAe-146 air tanker is described by the news reader and text on the screen (above) as having a “31,000 gallon tank”. That figure is off by a factor of 10 — they missed it by over 28,000 gallons. T41 can carry just under 3,000 gallons, maximum, and usually carries less due to density altitude limitations. If the 31,000 number was meant to be pounds instead of gallons, at 9 pounds per gallon for retardant it would still overstate the capacity by at least 400 gallons.

The air tankers that come closest to carrying 31,000 gallons are the 747 with 20,000 gallons, and the DC-10 at 11,600 gallons. All of the others flying today have a capacity of 3,000 gallons or less. The P2Vs usually carry less than 2,000. Coulson’s C-130Q that was awarded a contract this week will always carry 3,500 gallons when it begins dropping on fires in a few months.

The video shows T41 dropping on the Powerhouse Fire north of Los Angeles. The second time they show the drop near the end of the video, the news reader did not mention how the volume of the retardant trailed off at the end. The two BAe-146s have been criticized for having a consistent drop pattern for only the first 2,400 to 2,500 gallons, while the remaining 500 to 600 gallons dribbles out. Neptune has said they are outfitting their third and fourth BAe-146s this summer with an improved tank design which will fix some of the bugs with the tanking system. Then next winter they will modify the tanks in the first two BAe-146s, T40 and T41.

I watched some of the aerial firefighting Thursday while it was being streamed live, and saw an air tanker drop unlike any I have seen before. The same air tanker, T41, made two separate drops on the same pass. The ridgetop target was not straight. It had two straight sections but had an oxbow in the middle. The ridge was too crooked for the aircraft to make two sharp turns and treat the entire ridge in one long drop, so it flew a straight line and dropped maybe 1,000 gallons on the first straight section, stopped dropping while it passed by the crooked section of ridgetop, then when it was over the second straight section, opened the doors again and dropped another 1,000 gallons or so. Either T41 or another air tanker probably came back later and treated the oxbow section skipped before.

USFS to issue contracts for 3 next-gen air tankers

(Originally published at 11:15 a.m. MT, May 31, 2013; updated at 8:30 p.m., May 31, 2013)

The attorneys and U.S. Forest Service officials dealing with the contract protest that Neptune Aviation lodged when they were passed over for a next-generation air tanker contract have have decided that three of the seven line items on the solicitation are exempt from Neptune’s protest because the company did not bid on those line items. As a result, three companies were notified Thursday that they definitely will be issued five-year exclusive use contracts:

  • 10 Tanker Air Carrier for one of their two DC-10s
  • Minden Air Corp for a BAe-146
  • Coulson Aircrane (USA) for a C-130Q

The notification of the imminent awards comes 548 days after the USFS began the solicitation for next-gen air tankers. Two of the three companies told Fire Aviation that they have the awards in their hands. Bruce Palmer, a spokesperson with the USFS in Boise told us the awards and the award letters were sent Thursday.

The contracts will allow the companies to add an additional air tanker each year for up to five years, IF, and that’s a big IF, the USFS decides to add the aircraft and IF the agency has the funds to grow the air tanker program.

The other four line items on the pending next-gen contracts that are on hold because of Neptune’s protest are two MD87s provided by Aero Air, LLC of Hillsboro, Ore., and two Avro RJ85s from Aero Flite, Inc. of Kingman, Ariz.

The contracts to be issued to Minden, Coulson, and 10 Tanker, will require that the air tankers be fully certified and approved by the FAA and the Interagency AirTanker board by August 1, 2013, when their Mandatory Availability Period is scheduled to begin.

The DC-10 is already approved and has been dropping on fires for years.

It is thought that Coulson should be able to meet the deadline, since they are using a previously approved 3,500-gallon Aero Union tank system. The conversion of the C-130Q is nearing completion in San Bernardino and will be designated as Tanker 131, with a registration number of N130FF. Like the DC-10 (which always carries 11,600 gallons, however the new contract may change that), Tanker 131 will never have to reduce their retardant load due to density altitude. Future Coulson C-130 air tankers, if they are built, will have 5,000-gallon tanks, but on hot days at higher altitudes will occasionally have to fill at less than maximum retardant capacity.

Minden has recently been conducting flight characteristics tests of their BAe-146 supervised by an FAA pilot, as well as static tests on the ground to evaluate the tank system. Leonard Parker, Minden’s CEO, told us that they are close to obtaining the FAA’s Supplemental Type Certificate and expect to begin the airborne drop tests for the Interagency AirTanker Board very soon. He said the airtanker, designated Tanker 46, should be ready to drop on fires in 60 to 90 days.

USFS Chief Tidwell testifies about next-gen air tankers

USFS Chief Tom Tidwell, 5-22-2013In addition to talking about the C-27J in his testimony before a subcommittee of the Senate Appropriations Committee Wednesday, Chief of the U.S. Forest Service Tom Tidwell discussed at length the air tanker program, especially the contracting process for the next-generation air tankers.

During the hearing, which was primarily about the USFS budget, Senators Jack Reed (Rhode Island) and Jon Tester (Montana) asked many questions about the air tanker program. The entire hearing lasted almost two hours; you can watch a video of it HERE. You will see that there were three people in the audience, and only about five or six senators were present, out of the 30 that are members of the committee.

Chief Tidwell said he has the authority to override the protest filed by Neptune for being passed over for the next-gen air tanker contracts. If he does, it would be within the next couple of weeks and would be based on an “emergency” — a shortage of air tankers. On May 17 Colorado Senator Mark Udall issued a statement saying the protest should be overridden because Colorado lives and homes are at stake.

In reading between the lines of Senator Testor’s statements and questions, he appeared to be chiding Chief Tidwell for not awarding any next-generation air tanker contracts to a particular business in his state, Neptune Aviation. Neptune has two BAe-146s with at least interim approval by the Interagency AirTanker Board, and two more that the company expects to have ready to go later this summer. Neptune did, however, receive contracts on the “legacy” air tanker solicitation for some of their P2Vs and one BAe-146. [UPDATE May 23, 3013; Neptune was recently able to add a second BAe-146 to the contract as “additional equipment”.]

I transcribed some sections of the dialog:

At 43:28, Tidwell: “We will have an adequate air tanker fleet this year. We are anticipating between 24 and 26 planes to be available. We currently have nine aircraft under what we call a legacy aircraft which is seven P2s plus two BAe-146As that are currently on contract. We are in the process of awarding contracts for seven more aircraft which we call our next generation which are the faster planes we are trying to move forward to, that carry larger payloads. In addition to that we continue to work with the Air Force and Air Force Reserve to make sure the MAFFS units, the C-130Js and Hs are available again this year as a backup. We’ve also taken steps to be able to work with Alaska and Canada to bring down their [Convair] 580 planes if we need those aircraft.

So based on everything we’re moving forward with this year I feel confident that we will have a set of aircraft that we can respond.

In addition to that we are anxious to see what the Air Force, the decision that they make, if the C-27s are surplus and they become available, and we would definitely like to have seven more of those aircraft to be part of our overall fleet. They would be government owned but contractor operated. We are moving forward to actually look at what it would take to take our MAFFS units and modify those to fit into the C-27s so if those planes become available that we will be able to move as quick as we can to build those MAFFS units for those C-27s. ”

Senator Jack Reed
Senator Jack Reed

(Senator Reed asked a question about next gen contracts. Are you confident that you will have those next-gen aircraft under contract and useful this fire season?)

Tidwell: “Mr. Chairman, we are working through the process of the contract for the next generation and we have received a protest, that we will work through that protest. I do have the authority to override that protest and as we go through the process I’ll make that determination to ensure that we have the aircraft we need to be able to respond to fires this year.

We estimate that with the C-27s it would cost about $3 million per aircraft to build the MAFFS units and then to make some changes on the aircraft to make them usable for our mission and take some of the military equipment and armor off those aircraft that is no longer needed for our mission.”

Senator Jon Tester
Senator Jon Tester

(At 1:03 Senator Tester asked about the status of the aircraft on the next-generation contracts:)

Tidwell: “Once we work through the protest and actually award the contracts it is our expectation that those contractors that have the new contract awards will have their planes ready to go withn 60 days for testing.”

(Senator Tester asked, after the tests, when will they “be ready to fly?”)

Tidwell: “It’s our expectation that when they complete the tests they will be ready to fly. The aircraft that are being considered they are all FAA certified already so there isn’t that problem, they don’t have to deal with that. So they have to get their tanking systems to be able to use our performance tests.”

Senator Tester asked if they took into consideration when evaluating the potential contractors if they would be ready to fly this summer. Tidwell said, yes, they were expected to be able to be ready in 60 days. The contingency plan, he said, is to bring down the [Convair] 580s from Canada and to use the MAFFS.)

Tidwell: “We’ve been asking for the C-27s so that we at least have part of our fleet that is government owned so there is a guarantee that we will have some aircraft. So this has been an ongoing problem with these contracted aircraft.”

Tester: “My problem is not with the contracted aircraft per se, and I’m not for privatizing government, but my problem is that there were better options on the table that could be taken up by the Forest Service from my perspective and they didn’t do it. And you know exactly what I’m saying and all that.”

Tidwell: “We have a set of procedures that we follow when we award contracts. I can guarantee that there has been a high level of oversight provided and the process of being able to protest and have another level of review, that’s the process that we have to follow. And because of that our folks go to great lengths to be able to make sure that we are making right decisions based on what the contractors provided us and we have to make our best decisions.”

Tester: “The bottom line is we need to get the biggest bang for the buck and I’m not sure that because of the fact that we don’t know if these planes are going to be operational or not, whether we got the best bang for the buck.”

Tidwell said that “within the next week or so” he will make a decision about overriding the protest or not.)

At 1:39, Tester questioned again whether the seven next gen aircraft have FAA certification. Tidwell said it is his understanding that six do, and one made some air frame modifications, so it may not have the FAA certification. Tester asked Tidwell to confirm and get back to him.

Tester asked about the status of the C-27 transfer. Tidwell said it is his understanding that the Air Force is doing a study to determine if they want to do the transfer or not. The study could be done by September.

Tidwell anticipates the payload of the C-27 to be 1,800 gallons. Maintenance would be contracted. He said it would cost between $21 and $26 million to convert seven C-27s into air tankers.

USFS Chief Tidwell wants to install MAFFS units in the C-27Js

In testimony Wednesday before the Senate Appropriations Committee, Chief of the Forest Service Tom Tidwell said the agency hopes to obtain the C-27J aircraft that the Air Force may decide to declare surplus, and the USFS would outfit them with scaled down versions of the Modular Airborne FireFighting System (MAFFS) tank systems that are used in military C-130s. When asked, he said the C-27Js would hold 1,800 gallons of retardant in the MAFFS unit. When used in C-130s, the systems can carry up to 3,000 gallons, during favorable density altitude and fuel load conditions.

Some would say that choosing a MAFFS design rather than a conventional gravity powered tanking system is misguided. The retardant in a MAFFS is pumped out by a complex compressed air system and the delivery has been criticized as not being able to penetrate tree canopy as well as a gravity system. A MAFFS would have a much lower retardant capacity since it requires an air compressor, tanks for compressed air, and a complex system of additional valves and piping. All of that extra equipment means less capacity for carrying retardant. It also requires two loadmasters, in addition to the two or three person air crew, to operate the MAFFS, doubling the personnel cost.

I just don’t see the advantage of installing a MAFFS unit in a government-owned air tanker rather than a conventional gravity system. It holds less retardant and does a less than desirable job of retarding the spread of a timber fire.

Sure, you would be able to remove the MAFFS and use the plane for hauling cargo in about a day, but how often during the winter does the USFS need seven cargo planes? It could be used during fire season to haul firefighters, smokejumpers, and fire equipment, but then that makes it unavailable as an air tanker. So you’re either going to use it for hauling stuff, or as an air tanker, but not both.

It should be relatively simple to scale down an Aero Union gravity tank, which has been tested, approved, and used for decades in C-130s, to fit into a C-27J.

Coulson is using an Aero Union designed tank, slightly modified, for the C-130Q they are building right now in San Bernardino. The tank has wheels, and Britt Coulson told Fire Aviation that they can install or remove the tank in about 30 minutes, making it available to haul cargo.

Colorado Senator calls for the government to override Neptune’s protest of air tanker contracts

A Colorado Senator wants the federal government to override a protest that could delay the acquisition of seven next-generation air tankers this fire season.

Following the May 6 announcement by the U.S. Forest Service of their intention to award exclusive use contracts to five companies for the use of seven air tankers over a five to ten year period, one of the companies that failed to receive an award, Neptune Aviation, filed a protest with the Government Accountability Office. Unless the GAO grants emergency authority, Neptune’s action could delay by up to 100 days, until August 26, the date by which the new contracts could take effect.

Colorado Senator Mark Udall issued a statement saying the GAO protest should be overridden because Colorado lives and homes are at stake:

…”Wildfire season is coming, and I refuse to force Colorado communities to watch as preventable and containable wildfires are allowed to threaten lives and homes simply because of contractors’ squabbles. Make no mistake about it: This is an emergency, and this shortsighted protest will leave the U.S. Forest Service with outdated, Korean War-era air tankers to fight modern mega-fires,” Udall said. “That’s why I am calling on the U.S. Forest Service to override the protest filed this week and move forward with its next-generation air tankers contracts. Lives and homes are at stake, and I refuse to stand idly by as red tape suffocates any chance of the U.S. Forest Service finally acquiring these much-needed air tankers.”

Following the contract awards earlier this month, Udall cautioned private contractors that “Needless and costly delays will leave the Forest Service to fight modern mega-fires in the coming months with Korean War-era planes.”

Neptune’s protest is the second time awards for next-gen air tankers have been protested. The USFS began the contracting process for the next-gen air tankers November 30, 2011. On June 13, 2012 they announced awards for four companies, Neptune, Minden, Aero Air, and Aero Flite, which would have provided a total of seven air tankers. However two companies that were not going to receive contracts, Coulson Aviation and 10 Tanker Air Carrierprotested the awards, and the Government Accountability Office upheld their protest. At that time the contracts had not actually been signed, since negotiations about reimbursement if the contracts were cancelled had not been completed. The USFS went back to the drawing board. They amended and re-announced the solicitation on October 5, 2012 with a response due date of November 1, 2012. And on May 6, 2013 the USFS announced, again, their intention to award contracts.

The protest process worked during Round 2 for Coulson and 10 Tanker; they lost out in Round 1 and their protests led them to awards in Round 2. Neptune no doubt figures they have nothing to lose and everything to gain by their protest. The company has invested heavily in converting BAe-146s; conversions on two are complete and were used on fires in 2012. They have two others that they hoped to convert this year.

Neptune knows the contract protest backwards and forwards, since Ron Hooper, their CEO, as recently as November, 2010 worked for the U.S. Forest Service as the Director of Acquisition Management for the agency. His name is also mentioned in a summary of the 1987 U.S. Forest Service “airtanker scandal”. When qualified as a contracting officer, he reportedly made a determination after the transfer of the 28 aircraft to private companies that the transfer was void and they should be returned to the government. At the time Mr. Hooper was the staff assistant to the Forest Service Deputy Chief for Business Operations. (More information about a GAO bid protest.)

Neptune will have five P2Vs and one BAe-146 working this year under a new “legacy” air tanker contract announced in March.

Of the five companies that are slated to receive the new contracts for the faster, more dependable, and higher retardant capacity next-gen air tankers, only one has aircraft that are close to being ready to drop retardant on fires. 10 Tanker Air Carrier’s DC-10 Very Large Air Tankers which carry 11,600 gallons have been used on fires for years and should be ready to go. The other vendors are still in the process of physically converting their aircraft into air tankers and then have several hurdles to overcome.

After the contracts are actually signed and awarded, the companies have 60-90 days to complete the process of outfitting their aircraft with a tank design; prove the tank design in a controlled environment (dropping retardant into a grid of cups on the ground); be issued a Federal Aviation Administration Type Certificate; develop a maintenance and inspection program (Structural Integrity Program) for use of the aircraft as an airtanker and receive approval of it from the FAA; and be approved for a field trial (dropping retardant on real fires) by the Interagency Airtanker Board (IAB).

It would be surprising if all seven of the aircraft can meet these requirements in the time allotted. Coulson Aircrane, which is slated to receive a contract for a C-130Q, appears to be the closest other than 10 Tanker’s DC-10. Coulson is installing a retardant tank designed by Aero Union that previously had been approved by the IAB, however Coulson made some modifications. And various models of C-130s have been used as air tankers for decades.

The other companies, Minden Air, Aero Air, and Aero Flite, are converting, respectively, a BAe-146, two MD87s, and two AVRO RJ85s, all of which may be using new tanking systems that have not been tested until this year, at least on those models of aircraft.

For example Aero Air, also known as Erickson Aerotanker, may have problems with retardant being ingested into the MD87 jet engines mounted behind the wings. Designing and installing new tank systems on aircraft that have never before been used as an air tanker, such as the MD87 and AVRO RJ85 can expose some challenges that have to be overcome.

The Colorado Springs Gazette also has an article about this issue.

 

Thanks go out to Matt & Kelly.

Retardant tank for the C-27J. And, is the Air Force buying more C-27s?

Retardant tank for Coulson C-130Q

Coulson’s tank for their C-130Q

Coulson Aviation is putting the finishing touches on the 3,500-gallon retardant tank for their C-130Q, and they expect to roll it into the aircraft soon. Yes, it has wheels. Britt Coulson told Wildfire Today that they can install or remove it within 30 minutes. With or without the tank the air tanker can be pressurized. Without the tank, the C-130Q could be used for hauling cargo, or even smokejumpers, I suppose, if it were approved as a jumper platform.

Last week we posted an article, with photos, about the work the company is performing on the aircraft in a hangar in San Bernardino, California.

According to Mr. Coulson, the company bought from Aero Union “all the rights, engineering, and the drawings. We re-drew everything in Solidworks and re-designed the tank then manufactured it.” They are working with the USFS on the requirements for tests that involve dropping retardant into a grid of cups on the ground.

Use a similar tank for the C-27J?

Mr. Coulson said they are very interested in building tanks for the C-27J (an aircraft that the USFS may inherit from the Air Force) based on the same design, but scaled down to hold less retardant. He said the company responded to the U.S. Forest Service’s Request for Information posted in August to provide tanks for the aircraft, but the agency has not solicited for actual contract proposals yet. He believes the C-27J could carry somewhere between 2,500 and 3,000 gallons in an internal gravity-fed tank. Not all knowledgeable aviation folks we have talked with are optimistic that it could carry that much of a load. We have heard 1,800 gallons mentioned, and my own estimate is 1,800 to 2,300, but I am no expert.

(UPDATE, May 20, 2013: It was pointed out to us that converting the military version of the C-27J into a civilian air tanker would result in thousands of pounds of hardware being removed, perhaps with 2,000 to 4,000 pounds of weight savings. This could increase the retardant capacity by as much as 450 gallons, raising our estimate of the tank size to 2,000 to 2,650 gallons. This assumes an internal, gravity-fed tank system. A pressurized design, like the military MAFFS, would have a much lower capacity, requiring tanks for compressed air, additional valves and piping, and an air compressor.)

The Air Force has decided they don’t want any of their five-year-old C-27Js. You have to wonder why an agency would want to give away hundreds of millions of dollars worth of almost-new aircraft.

Tom Harbour, the U.S. Forest Service National Director of Fire and Aviation Management, was quoted in the Missoulian Tuesday on the subject of the C-27J:

“We are still working with the Department of Defense to see if we can get up to seven C-27J Spartans,” Harbour said. “If we acquire those platforms, we would modify them so we could use them as a medium air tanker. They’re not the size that is going to be able to carry type 1, large air tanker-capacity tanks, but we think they’re a very capable platform.” The Spartan is an Italian-made turboprop-powered cargo plane. The U.S. Air Force has offered to transfer up to 14 of the planes free to the Forest Service. Harbour said the plane is capable of carrying smokejumpers, but has only had preliminary testing as a retardant bomber.

If the USFS does procure and convert the C-27Js into air tankers, they may choose to pay contractors to fly and maintain them, similar to the CAL FIRE model for their 23 S-2T air tankers. CAL FIRE’s current support contractors are DynCorp and Logistics Specialties Incorporated. DynCorp provides air tanker and airtactical plane pilot services, and all aircraft maintenance services. (All CAL FIRE helicopters are flown by CAL FIRE pilots, but maintained by DynCorp.) LSI provides procurement and parts management services.

Fire Aviation has learned that some USFS aviation personnel have talked informally with DynCorp about a government-owned, contractor-operated program. According to the Missoulian article, Neptune would also be interested in bidding on a contract to provide these services.

Is the Air Force buying more C-27Js?

And just to confuse the issue further, when I was searching FedBizOpps.gov for the USFS Request for Information about the C-27J retardant tanks, the search results included a Sources Sought Synopsis survey placed there by the Air Force May 10, 2013. The agency is looking for companies that can manufacture more C-27Js. While the military says they don’t want the ones they have, and are giving those away and saying good riddance, they are considering buying more. Their reasoning is, they are….

…contemplating procurement of C-27J aircraft, in accordance with Congressional language that states “The secretary of the Air Force shall obligate and expend funds previously appropriated for the procurement of C-27J Spartan aircraft for the purposes for which such funds were originally appropriated.”

Here’s an idea.

Instead of buying more C-27Js at $53 million each, contemplate instead, if it is economically feasible, designing and building some purpose-built air tankers to enhance our homeland security.

Neptune to protest next-generation air tanker contract awards

Neptune Aviation has announced that the company will lodge a protest with the Government Accountability Office over the contracts that the U.S. Forest Service intends to award for next-generation air tankers. On May 6 the USFS said they intended to give contracts to five companies for a total of seven air tankers to provide turbine or jet powered aircraft that can carry more retardant and fly faster than the Korean War vintage “legacy” air tankers such as the P2V that the federal wildfire agencies have been relying on for decades. Neptune did not receive one of the awards even though they have been the primary supplier of air tankers to the federal government for the last several years.

When the next-gen contracts were announced May 6, the pilots of all five Neptune Aviation air tankers that were working and available for fire assignments walked away from their aircraft in California and New Mexico a little after noon. The aircraft were unstaffed until Tuesday morning. Dan Snyder, Neptune’s Chief Operating Officer, said it was done for safety reasons:

We did not want our crews worried about the company’s future, their jobs, BAe program, etc, instead of being 100% mission focused. We took the opportunity to get clear and concise information to them and allow for questions and concerns to be addressed.

This is not the first time contract awards for next-generation air tankers have been contested. The USFS began the contracting process for the newer air tankers November 30, 2011. Almost seven months later on June 13, 2012 they announced awards for four companies, Neptune, Minden, Aero Air, and Aero Flite, to provide a total of seven air tankers. However two companies that were not going to receive contracts, Coulson Aviation and 10 Tanker Air Carrierprotested the awards, and the Government Accountability Office upheld their protest. At that time the contracts had not actually been signed, since negotiations about reimbursement if the contracts were cancelled had not been completed. The USFS went back to the drawing board for four months. They amended and re-announced the solicitation on October 5, 2012 with a response due date of November 1, 2012. The second time the awards were announced last week was seven months after the second solicitation was issued and 523 days after the process first began. If the USFS has to go through a third round of solicitation due to this latest protest, the appearance of next-gen air tankers over wildfires will be delayed for many more months.

The two companies that filed protests following round 1, Coulson and 10 Tanker, both received awards after round 2, which may have given confidence to Neptune to try the same tactic and perhaps force a third round.

Neptune has invested heavily in four BAe-146 aircraft, retired airliners with more than 20 years of service. Two have been converted to air tankers, Tankers 40 and 41, and have interim approval from the Interagency Air Tanker board. But their retardant delivery performance has been criticized, since the last several hundred gallons of retardant does not exit the tanks quickly enough. Neptune thinks they have a fix for the problem and the next two BAe-146s being converted now, Tankers 10 and 01, will have an improved tanking system. They expect to begin drop tests with Tanker 10 no later than June 10 of this year, Ron Hooper, their Chief Executive Officer said. The company will retrofit the tanks in Tankers 40 and 41 with the new variant of the tank next winter. One of them is currently on the USFS legacy contract for this year.
