Harvey Gulf International Marine said today that it’s received an AiP/Approval in Principle from ABS/American Bureau of Shipping, as well as U.S. Coast Guard design base approval for a new ATB/articulated tug barge vessel for bunkering liquefied natural gas.

Harvey Gulf’s ABS-approved proposed LNG bunker barge is to be 324 feet long (98.7 meters) with an LNG cargo capacity of 3,996 cubic meters – more than a million gallons.

Separately, a key industry source confirms that Shell, already the charter customers for three of Harvey Gulf’s LNG-fueled platform supply vessels serving deepwater rigs in the Gulf of Mexico (HHP Insight, February 23), has signed on for two more.

Harvey’s new ATB is to have four independent 999-cubic meter Type C LNG tanks for a combined capacity of nearly 4,000 cubic meters – more than a million gallons. The vessel will be able to load and discharge LNG at a rate of 600 cubic meters (nearly 160,000 gallons) per hour and travel in excess of 10 knots.

“The development of this vessel design highlights our commitment to and involvement in the strengthening of the domestic LNG marine fuel market, and our continued commitment to a leadership role in developing a robust supply infrastructure,” Harvey Gulf chairman and CEO Shane Guidry says in today’s release.

“Working closely with its design partner Waller Marine,” he said, as well as ABS and the Coast Guard, Harvey “has developed the design package ahead of construction thereby minimizing the potential for delays and significant cost impacts to the project during construction.”

Wärtsilä & Air Liquide

The ATB design, with 324-foot (98.7-meter) barge pushed by a 128-foot (39 -meter) ABS-classed tug, incorporates a robust fire and safety system. In addition to Waller Marine, Harvey is working with Wärtsilä as the new vessel’s cargo system and overall integrator. The design includes a sub-cooler for boil off gas management developed with Air Liquide using TB 350 Turbo-Brayton technology.

Also according to today’s release, the new ATB design “meets all domestic and International requirement of a gas carrier, including the existing regulatory requirements defined in 46 CFR Subchapter D, 46 CFR Subchapter 0, the International Code for the Design and Construction of Ships Carrying Liquefied Gases in Bulk, 2016 edition (IGC Code), and applicable American Bureau of Shipping (ABS) Steel Barge Rules: Part 5 Chapter 2 Section 5 Liquefied Gas Tank Barges (as modified per 2016 IGC Code), and ABS Steel Vessel Rules Part 5C Chapter 8 Sections 1-19 (as modified per 2016 IGC Code and referenced within the ABS Barge Rules).”

‘Methodical Approach’

“This project and the methodical approach in which it has been developed is very different from any other similar vessel design project undertaken thus far,” said Chad Verret, executive VP for LNG operations at Harvey Gulf.

“We are designing a gas carrier that will provide ship-to-ship transfers of LNG to vessels utilizing LNG as a fuel as well as do ship-to-shore transfers to the small scale marine distribution infrastructure,” Verret says in today’s ATB announcement.

Harvey Gulf expects to commence shore-to-ship bunkering of its LNG vessels at Port Fourchon next month.

The new vessel will be able to load to load at any SIGTTO/Society of International Gas Tanker and Terminal Operators-compliant off-take facility, he said.

Pioneering Ships and Fueling Facility

Guidry noted today that Harvey operates North America’s first LNG-fueled PSVs and the first marine LNG marine fueling terminal in the U.S. – a shore-to-ship installation at Port Fourchon, La.

Harvey Gulf’s Harvey Liberty, the third of six LNG-fueled offshore supply vessels by the New Orleans-based company, entered service with charter customer Shell earlier this year (HHPi, May 12) following earlier deployments of Harvey Energy and Harvey Power for service with Shell.

More PSVs for Harvey

Also for service with Shell is Harvey Freedom, the fourth of the series, which is slated to roll out at the company’s Mississippi yard on September 20, with launch shortly thereafter. Delivery is expected to take place in March.

Vessel number five, Harvey America, is expected to follow for delivery late in 2017, also for service with Shell.
