Use of LPG as a marine fuel continues to gain ground. Singapore-based Petredec Holdings (Eastern) PTE Ltd this month signed a contract for the construction of three 93,000 cu.m LPG carriers at Jiangnan Shipyard in China. The contract includes options for three further ships.
Each vessel will be powered by individual MAN B&W 6G60ME-LGIP dual-fuel engines, capable of running on LPG.
With an existing fleet of 21 VLGCs, Petredec is already the second-largest owner of VLGCs in the world and with an average age of 3.5 years, the fleet is the youngest in its market segment.
“Petredec has always been at the forefront of new technology and this order continues our tradition of investing in the most efficient and environmentally friendly solution,” said Philip Harwood, Petredec Fleet Director. “We are convinced that using LPG as bunker fuel in the MAN Energy Solutions ME-LGIP engine is the best contributor to achieving the targeted 40% reduction in CO2 emissions by 2030.”
Giles Fearn, Petredec Group CEO commented “We are proud to have ordered the next generation of VLGCs, which marks an important step for both us and the industry towards decarbonization by emitting 30% less CO2 than the previous generation 84,000-cubic-meter ships burning LSFO. It clearly positions Petredec as the pre-eminent owner of VLGC’s with dual-fuel LPG and we are excited for what this next chapter in the company’s evolution will bring.”
Bjarne Foldager, Senior Vice President and Head of Two-Stroke Business at MAN Energy Solutions, said: “We are moving towards a zero-carbon future and there is a strong global push towards sustainability. As we pass the 2020 sulfur cap and approach the IMO’s 2030 and 2050 targets, companies committed to sustainability are becoming increasingly attractive. This project displays Petredec’s committment to decarbonization and showcases MAN Energy Solutions’ dual-fuel engine portfolio that is future-proofed to handle whatever alternative fuels come to prominence in the decades ahead.”
The initial, firm, three vessels are scheduled for delivery in January, March, and May 2023, and the optional vessels within the second and third quarters of 2023.
The new order follows on the heels of last month’s announcement by MAN PrimeServ, MAN Energy Solutions’ after-sales division, that it had successfully converted the main engine aboard the LPG carrier, BW Gemini, from an MAN B&W 6G60ME-C9.2 type to an MAN B&W 6G60ME- LGIP unit. The BW Gemini is part of the fleet of Oslo-listed, BW LPG.
In general, notes MAN Energy Solutions, harnessing LPG propulsion translates into cleaner, more efficient engines that are cheaper to maintain. In addition, the fuel flexibility of dual-fuel engines ensures full redundancy for uninterrupted operations.
Compared to 2020-compliant fuel oils, using LPG as a fuel reduces SOx by 99%, CO2 by 15%, NOx by 10%, and particulate matter by 90%.
