Cryogenic engineering and transportation specialist INOXCVA has supplied LNG fuel tanks for the first stage of Crowley Maritime’s LNG-fuelled 2,400 teu con-ro vessel project.

The three 770m3 tanks, delivered to TGE Marine Gas Engineering, were manufactured at INOXCVA’s facility in Kandla, India. They are destined for the VT Halter Marine shipyard in the USA.

The double-walled, vacuum-insulated C-tanks offer a hold time in excess of 58 days, compared to just 8-10 days for conventionally insulated tanks, according to INOXCVA. When installed they will support the operation of the vessels' MAN B&W ME-GI main engines and auxiliary generators when running on LNG.

A second set of similar tanks will be delivered for the second vessel later this year. Project partners in the design of the tanks included owner Crowley, VT Halter, main contractor MAN Diesel & Turbo, classification society DNV GL, the US Coast Guard and fuel system designer – and INOXCVA’s direct customer – TGE Marine Gas Engineering.

“INOXCVA has invested in state of the art facilities to manufacture these type of fuel gas tanks and similar large tanks with a high degree of quality, reliability and quicker lead times needed to meet the growing requirement for shorter overall project schedules,” the company said.

As reported, Crowley placed the order for two LNG-fuelled ro-ro containerships with VT Halter in early January 2014. The vessels are scheduled for delivery in the second and fourth quarters of 2017.
