Lloyd’s Register (LR) has granted an approval in principle (AiP) to Hyundai Heavy Industries’ (HHI) new very large gas carrier (VLGC) design that can use liquefied petroleum gas (LPG) as fuel.

The AiP has been granted to HHI according to the new International Maritime Organization’s (IMO) International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code).

It will help VLGC operators address the issue of reducing greenhouse gas (GHG) emissions.

The VLGC design was developed by HHI in partnership with Hyundai Global Service (HGS) and LR.

Hyundai Global Service CEO and HHI Group ship / offshore marketing deputy COO Kisun Chung said: “We have focused on developing the safe design for LPG-fuelled propulsion system.

“We are pleased to introduce the reliable design of VLGC with LPG burning system in the market for new building and also conversion vessels so that VLGC players can have environmentally friendly vessels and maximise their benefits using their cargo carried onboard the vessels.”

“We have focused on developing the safe design for LPG-fuelled propulsion system.”

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.”
