MAN Energy Solutions (MAN) was also involved in the joint development of the VLGC design as an engine designer.

The company recently launched its new two-stroke engine type, a dual-fuel MAN B&W ME-LGIP engine that can operate on LPG.

As part of its involvement in the project, LR facilitated a high-level hazard identification (HAZID) workshop for the LPG fuel supply system and related aspects in line with the company’s ShipRight Procedure Risk Based Designs (RBD).

Results of the HAZID were used to review the VLGC design.

LR South Korea chief representative and marine manager Jin-Tae Lee said: “We are very pleased with our role in this JDP to help the shipyard develop the reliable LPG-fuelled VLGC design free of latent risks due to the inherent LPG characteristics, and to enable the shipping industry to enjoy the commercial benefits with confidence in the safety and operability of the LPG burning system.”
