Hull Vane Experiment on 52 Meter OPV

“This project video shows the process from design to sea trials of a Hull Vane retrofit on the 52 m Offshore Patrol Vessel Thémis from the French Affaires Maritimes. The installation was done by CMN Cherbourg, which was also the builder of this vessel (delivered in 2004).”

I have posted on this particular innovation before, twice in fact, in 2017, “Hull Vane Claims Improved Performance,” and in 2015, “Hull Vane on an OPV,” but now we have another example and new information. This time the example is a mid-life up-grade on a vessel slightly larger but otherwise similar to the Webber class WPCs, the OPV Thémis from the French Coastguard (Affaires Maritimes) 409 tons, 6,310 HP, 52.5x9x2.27 meters (172.2×29.5×7.45 feet)

MarineLink reported this experiment, but I also found an excellent report with more photos here.

The results of this trial:

Comparison with the benchmark sea trials – conducted in January in exactly the same conditions – by CMN’s sea trial team showed a reduction in fuel consumption of 18 percent at 12 knots, 27 percent at 15 knots and 22 percent at 20 knots. The top speed increased from 19.7 knots to 21 knots.

The earliest post, “Hull Vane on an OPV,” reported the effects of applying the innovation to a 108 meter Dutch Holland class OPV, a ship very much like the Offshore Patrol Cutter (OPC).

  • They claimed a 12.5% reduction in fuel consumption, overall. Specifically they claimed. “…runs were done to determine the resistance at 5 knots, 12.5 knots, 17.5 knots and 22.5 knots, showing resistance reductions of 1.3%, 13.7%, 15.3% and 11.1% respectively.”
  • A 4% reduction in heave,
  • A 7%% reduction in pitch, and
  • A 13% reduction in vertical acceleration at the flight deck.

A comment on this earliest post, received from the Hull Vane team, noted.

“The performance is better however on the fuller-bodied and wider-transomed hull shapes like the typical US Coast Guard cutters, which we would very much like to do some work on.”

The Hull Vane web site has a number of publications, testimonials, and case studies, including a Nov. 2017 report on a 25 meter patrol boat. that claimed a 20% reduction in fuel consumption. It also noted  “RPA 8 is the eighth vessel to be equipped with a Hull Vane®, and ten other ships which will have a Hull Vane® are currently under construction.”

As the new ships enter service, we will probably see the Webber class using more fuel than the 110s, and almost certainly the OPCs will use more fuel than the 210s and 270s.

I would think we would want to check this out, starting with contacting the Dutch Navy and the French Affaires Maritimes to get their take on the tests. Did they think they were successful? Are they going to use Hull Vane on their own ships? If not, why not? That would cost us very little. If the responses are positive, it would make a great R&D project. Bollinger might welcome the opportunity to try one out on a new construction Webber class. The baseline capabilities of the class are already well documented.

 

Bollinger Wants to Build CG Icebreakers in Tampa

MarineLink provides what is almost certainly a quote of press release from Bollinger stating they hope to build the three heavy and three medium icebreakers the Coast Guard has been saying it needs in Tampa. They are reminding every one (hay, you guys in Congress) how many jobs this could mean for Florida.

This cannot hurt our case for building more than one icebreaker.

NavyRecognitions reports that, “Eastern Shipbuilding Group (ESG) has successfully conducted its Final Critical Design Review (FCDR) with the United States Coast Guard on 29 June 2018 for the Offshore Patrol Cutter (OPC) Program.”

Award for construction of the first of class, USCGC Argus, is expected in the Fall.

Chinese Nuclear Icebreaker Planned

China Defense Blog reports that China is has begun the process to design and build a nuclear powered icebreaker, as a prelude to building a nuclear powered aircraft carrier.

The post includes a quotation that is wrong on a couple of counts.

“The US and former Soviet Union used their experience with nuclear-powered icebreaker ships to build a nuclear-powered aircraft carrier, he noted.”

The US, of course, never built a nuclear icebreaker, and the Soviet Union never built a nuclear carrier. The Soviets did build some very large cruisers with a hybrid nuclear and conventional steam powerplants, but those were their only nuclear powered surface warships. Both nations built nuclear submarines before building nuclear surface warships. China has also already built several classes of nuclear submarines

Navy Will Release New 30-Year Ship Repair, Modernization Plan with Annual Shipbuilding Report–USNI

The Navy has announced that they will release not only a 30 year shipbuilding plan, but also a 30 year ship repair and modernization plan.

He acknowledged that the timing of ship maintenance availabilities are prone to change, as deployments are extended, one ship is swapped for another to meet a warfighter need, and so on. But while the planning is complex, he said, “the only thing I know is, the best way to start getting after a complex issue is laying out at least what you know and laying that out as a baseline, so then when you do have to do – whether it’s for operational reasons or whatever – have to do changes, you’re changing from a known baseline and you can more quickly understand what the second- and third-order effects are.”

I still don’t think the Coast Guard has ever submitted their 20 year plan as mandated by GAO and Congress. We have discussed the need for a long term shipbuilding plan numerous times. These are only two:

I suspect the 20 year plan was stalled in the Department.

It is really important to build an understanding of future needs. It seems this was a part of the problem in getting a realistic shipbuilding budget. We should anticipate replacing all our ships when they reach 30 years of age. As that time approaches we can reevaluate and perhaps delay replacement if they are holding up well, and we will be heroes.

We really have to tell the administration and the Congress what we need. To do that I would reiterate the need to periodically redo the Fleet Mix simulation and study. The last one was done about ten years ago and still assumed multiple crewing of the Bertholf Class NSCs and Offshore Patrol Cutters. (Crew Rotation Concept).

Report to Congress on U.S. Coast Guard Cutter Procurement, 23 May 2018

OPC “Placemat”

Mr. O’Rourke has been busy, in addition to the report on Icebreakers, the latest edition of the Congressional Research Service report on Coast Guard Cutter Procurement, also by Ronald O’Rourke, was also published on 23 May, 2018. You can see it here. 

I have reproduced the summary immediately below.  Note that the price for the OPCs is already surprisingly low. 

The Coast Guard’s acquisition program of record (POR) calls for procuring 8 National Security Cutters (NSCs), 25 Offshore Patrol Cutters (OPCs), and 58 Fast Response Cutters (FRCs) as replacements for 90 aging Coast Guard high-endurance cutters, medium-endurance cutters, and patrol craft. The Coast Guard’s proposed FY2019 budget requests a total of $705 million in acquisition funding for the NSC, OPC, and FRC programs.

NSCs are the Coast Guard’s largest and most capable general-purpose cutters; they are intended to replace the Coast Guard’s 12 aged Hamilton-class high-endurance cutters. NSCs have an estimated average procurement cost of about $682 million per ship. Although the Coast Guard’s POR calls for procuring a total of 8 NSCs to replace the 12 Hamilton-class cutters, Congress through FY2018 has funded 11 NSCs, including two (the 10th and 11th) in FY2018. Six NSCs are now in service, and the seventh, eighth, and ninth are scheduled for delivery in 2018, 2019, and 2020, respectively. The Coast Guard’s proposed FY2019 budget requests $65 million in acquisition funding for the NSC program; this request does not include additional funding for a 12th NSC.

OPCs are to be smaller, less expensive, and in some respects less capable than NSCs; they are intended to replace the Coast Guard’s 29 aged medium-endurance cutters. Coast Guard officials describe the OPC program as the service’s top acquisition priority. OPCs have an estimated average procurement cost of about $391 million per ship. On September 15, 2016, the Coast Guard announced that it was awarding a contract with options for building up to nine ships in the class to Eastern Shipbuilding Group of Panama City, FL. The first OPC was funded in FY2018 and is to be delivered in 2021. The Coast Guard’s proposed FY2019 budget requests $400 million in acquisition funding for the OPC program for the construction of the second OPC (which is scheduled for delivery in 2022) and procurement of long leadtime materials (LLTM) for the third OPC (which is scheduled for delivery in 2023).

FRCs are considerably smaller and less expensive than OPCs; they are intended to replace the Coast Guard’s 49 aging Island-class patrol boats. FRCs have an estimated average procurement cost of about $58 million per boat. A total of 50 have been funded through FY2018. The 27th was commissioned into service on April 20, 2018. The Coast Guard’s proposed FY2019 budget requests $240 million in acquisition funding for the procurement of four more FRCs.

The NSC, OPC, and FRC programs pose several issues for Congress, including the following: 

  • whether to fully or partially fund the acquisition of a 12th NSC in FY2019; 
  • whether to fund the acquisition of four FRCs in FY2019, as requested, or some other number, such as six, which is the maximum number that has been acquired in some prior fiscal years; 
  • whether to use annual or multiyear contracting for procuring OPCs; 
  • the procurement rate for the OPC program; 
  • planned procurement quantities for NSCs, OPCs, and FRCs; and 
  • initial testing of the NSC.

Congress’s decisions on these programs could substantially affect Coast Guard capabilities and funding requirements, and the U.S. shipbuilding industrial base.

“Build a Great White Fleet For the 21st Century”–USNI Proceedings

The US Naval Institute Proceedings May 2018 edition has an article, “Build a Great White Fleet for the 21st Century,” that recommends greater Coast Guard funding to support Combatant Commanders. It is written by Captain David Ramassini, USCG. The accompanying bio states,

“Captain Ramassini is an Operation Iraqi Freedom veteran and cutterman who has served in the Pentagon as Coast Guard Liaison on the Joint Staff and also in the Office of Secretary of Defense. Captain Ramassini is slated to assume his fifth command as the plankowner commanding officer of the national security cutter Kimball (WMSL-756).”

Unfortunately the article is “members only.” If you are a regular reader of my blog, you probably should also be a US Naval Institute member, but for those who are not, I’ll try to summarize his argument, including some quotations. After reviewing the article, I’ll offer some thought on how, and where, we might provide some assistance to the Combatant Commanders.

The Article

Captain Ramassini contends improved maritime governance and suppressing transnational crime is in the US interest where ever it occurs.

“As the line between terrorist and criminal activities continues to blur, the transactional connections between a wide range of unlawful organizations is likely to cloud the distinction between law enforcement and military operations.”

The Geographic Combatant Commanders (GCC) need afloat assets to aid in dealing with these problems.

Source: UNODC, responses to annual questionnaire and individual drug seizure database

The Coast Guard is uniquely qualified to leverage “vast authorities; capabilities; and interservice, interagency, intelligence community, and international partnerships” in support of Geographic Combatant Commanders (GCC).

There are not enough Coast Guard assets to do this now.

To provide additional assets funding for the fleet needs to be rebalanced, moving money from the Navy to the Coast Guard.

Rebalancing the national fleet composition would improve relationships and provide the United States and our partners advantages in a complex world filled with threats that go beyond the nation-state.

Recognizing the Coast Guard for the unique national, international, diplomatic, economic, and intelligence power that it is, the current administration has the opportunity to turn this tide and make the national fleet great again by directing a smart business decision. Specifically, prioritize Coast Guard cutter production to grow the fleet and provide a more cost-effective and adaptable instrument for the nation. A 21st-century Great White Fleet of Coast Guard cutters would begin a new era of sea power better suited to promote rule of law through cooperative partnership and distributed lethality, and allow the U.S. Navy to refocus its efforts on high-intensity conflict. It is time to rethink international engagement using the Coast Guard—an armed force at all times, but a more cooperative power known for its olive-branches-over-arrows approach.

Coast Guard national security, offshore patrol, and fast response cutters could serve as powerful instruments for GCCs. They are large enough to operate globally, yet small enough to gain access and foster cooperative partnerships. In addition, these more affordable naval assets could be produced more expediently than Navy surface combatants to build a credible national fleet. The goal of a 355-ship Navy needs to be expanded to a 400+ ship national fleet with utility across civil and military disciplines and a better return on investment.

It is time to change the costly Navy-centric approach toward peace and security and focus on restoring the underpinnings of rule of law to regain the trust and confidence of partner nations. The Coast Guard is capable of more finely tuned and less costly persistent presence. It is an affordable, accountable, and reliable instrument of national power well equipped to execute international engagement. Bolstering white hull numbers within the national fleet by doubling the number of cutters could provide a 21st century advantage to the United States and our international partners in this ever-evolving global environment.

Captain Ramassini suggests that large cutters could be upgraded so that they can fill the frigate role.

One approach worth examining is up-arming the Coast Guard’s fleet with a vertical-launch system (Mk-41 VLS) and SeaRAM close-in weapon system to provide increased warfare interoperability. Imagine a forward-deployed “international security cutter” capable of operating with a carrier strike group and/or surface action group and assuming a role historically filled by a Navy frigate.

Commentary

There are currently six Unified Combatant Commands. Two, NORTHCOM and SOUTHCOM already have substantial Coast Guard assets available, although SOUTHCOM could use more. CENTCOM has the six WPBs of PATFORSWASIA. Three Unified Combatant Commands, PACOM, EUCOM, and AFRICOM, have no regular Coast Guard representation.

EUCOM (European Command) probably has far less need for a US Coast Guard presence, since they already have several sophisticated coast guard organizations among allied nations.

PACOM probably could use more Coast Guard assets for capacity building and suppression of Illegal, Unregulated, and Unreported (IUU) fishing in the Western Pacific. Seventh Fleet has already asked for more Coast Guard presence to confront Chinese white hulls.

Africa has a serious problem with Maritime crime and could use training, capacity building, and more international inter-agency cooperation. The Coast Guard has sent ships to the area intermittently, but the area has been largely neglected. China is making serious inroads in Africa. We need a presence, but gray hulls are not what we need. The six boats of Patrol Force South West Asia (PATFORSWA) could help address the problem in East Africa, but that would require some sharing by CENTCOM. There is an unrealized opportunity to do a lot of good in West Africa, particularly in the Gulf of Guinea where piracy, kidnapping, IUU fishing, and other marine crimes are common.

Gulf of Guinea, from Wikipedia

To maintain a single large cutter off the West coast of Africa or in the Western Pacific would require three ships in rotation, assuming they are homeported in the US. Larger ships are more difficult to homeport in foreign ports, smaller vessels are likely more feasible.

It appears more likely we could replicate the six boat PATFORSWA organization with similar organizations in East Africa and the Western Pacific. There are several ports in each area that might be worth considering.

Obviously we would not send more now overage 110s, we would be sending Webber class WPCs. This would require extending the current program beyond the 58 in the program of record. There is already discussion about six additional WPCs to replace the six 110s assigned to CENTCOM. Adding six for AFRICOM and six for PACOM would extend the current program by two or three years. The shipbuilding costs for 12 more WPCs are on the order of $700M spread over two or three years, not much more than a single NSC. Basic personnel requirements for 12 vessels with a crew of 24 are 288 crew members. Rotational crews and supporting personnel would probably push this up to about 500, a notable increase for the Coast Guard, but “small change” in the defense budget. The PATFORSWA costs are paid for from the DOD budget, so I would expect a similar arrangement for similar squadrons assigned to AFRICOM and PACOM.

Perhaps at some point. we should also consider a similar forward deployed squadron for SOUTHCOM.
