GEV completes ship specification engineering for C-H2

Global Energy Ventures has completed the ship specification engineering for its proposed 430-tonne pilot compressed hydrogen (C-H2) ship for review by a shipping regulator.

Ship specification engineering and drawings, stability analysis and tank design calculations have been submitted to the American Bureau of Shipping (ABS) with approval-in-principle (AIP) expected by the end of the Q3 in 2021.

GEV is leveraging the 2,000-tonne AiP program to fast-track AiP for this pilot ship and to ultimately target full-class approvals by late 2022.

The prime focus of the approval was the design and safety of the compressed hydrogen containment system. ABS undertook extensive hazard identification analysis (HAZID) prior to issuing the AiP.

In June 2021, GEV also signed a memorandum of understanding (MoU) with technology group Wärtsilä to cooperate on the inclusion of Wärtsilä propulsion systems in GEV’s compressed hydrogen ships.

C-FER Technologies has recently completed an independent analysis of hydrogen permeability which supported GEV’s design assumptions and the selection of a stainless-steel inner liner.

The company is supporting the selection of carbon steel and welding techniques in preparation for prototype construction and testing in 2022.
