BW LPG TO RETROFIT MORE LPG TANKERS FOR DUAL FUEL

BW LPG TO RETROFIT MORE LPG TANKERS FOR DUAL FUEL

Wednesday, December 16, 2020 

LPG carrier ship operator BW LPG will convert the MAN B&W 6G60ME-C9.2 type engines to MAN B&W 6G60ME-C9.5-LGIP dual-fuel type on three more vessels, making them capable of operating on fuel oil and LPG.

This contract exercises another option of a 4+4+4+3 order placed through MAN PrimeServ, bringing the number of dual-fuel LPG carriers in the BW fleet to 15. The confirmation of this latest option follows the successful ME-LGIP conversion in late October 2020 of the main engine aboard BW LPG’s LPG carrier, BW Gemini making it the world’s first commercial vessel to be propelled by a two-stroke LPG dual-fuel engine.

Pontus Berg, BW's EVP Technical and Operations, LPG, said: “Retrofitting allows us to minimise our carbon footprint – the process emits up to 97% less carbon dioxide compared to a newbuilding construction. Retrofitting also means that we do not add additional tonnage that the world does not need. In addition, BW LPG’s fleet is already widely recognised amongst charterers for its efficiency, and so retrofitting its vessels to dual-fuel LPG would help to further reinforce the company’s strong reputation in this area.”

Bjarne Foldager, SVP and Head of Two-Stroke Business, MAN Energy Solutions, said: “We are very happy to confirm this option for a further three retrofits, which in great part is due to the recent successful conversion of the BW Gemini that has since re-entered service. There is no doubt but that we are moving towards a zero-carbon future with a strong global push towards sustainability. These new conversions display BW LPG’s commitment to decarbonisation and showcase our dual-fuel engine portfolio that is future-proofed to handle whatever alternative fuels come to prominence in the decades ahead. Apart from the 15 retrofits for BW LPG, three new orders in November bring our current total of newbuilding orders for the ME-LGIP engine up to 51 – a number we expect to significantly increase this month [December 2020]. The vast majority of current orders for LPG carriers over 30,000 cubic metres are with ME-LGIP technology, enabling these vessels to use their own cargo as fuel in the future. In my view, LPG as a low-carbon fuel is well on its way to becoming the new market standard in this segment.”

With LPG as a marine fuel, the BW Gemini’s output efficiencies rise by around 10% against fuel oil. LPG is said to be a better option economically than compliant fuel oil, with dual-fuel flexibility for redundancy and to guard against fuel price fluctuations, while offering maintenance savings . The ability to use LPG cargo as a supplemental fuel source also reduces time and fees for fuel bunkering.

MAN PrimeServ’s research shows that a retrofitted vessel generates 35 times less CO2 emission compared to a newbuild vessel and, compared to 2020-compliant fuels, using LPG as a fuel would reduce: SOx by 99%, CO2 by 15%, NOx by 10%, and particulate matter by 90%.
