MAN Energy Solutions’s after-sales division, MAN PrimeServ, has announced the signing of a contract to retrofit two LPG carriers for Tianjin Southwest Maritime, the Chinese liquefied-gas carrier operator. The COSCO Shipping Heavy Industry (Guangdong) yard will host the respective conversions of the individual MAN B&W 6G60ME-C engines aboard the ‘Gas Gemini’ and ‘Gas Aquarius’ to dual-fuel MAN B&W 6G60ME-LGIP units capable of running on LPG. The two vessels will be retrofitted in parallel, beginning May 30th 2023. In a notable first, PrimeServ will jointly carry out the work with CSSC Marine Service, the after-sales subsidiary of CSSC Marine Power Group. The contract signing comes in the wake of Oslo-listed BW LPG – the world's leading owner and operator of LPG vessels – announcing in June 2022 that it, under MAN PrimeServ’s supervision, had converted the main engine of the ‘BW Malacca’ to dual-fuel running. The last such conversion for a series of 15 LPG carriers, all work was carried out at Yiu Lian Dockyards in Shenzhen, evidence of China’s ability to successfully execute such retrofits.
