MAN Energy Solutions’ aftermarket division, MAN PrimeServ, has announced the signing of a contract to upgrade two LPG carriers for Tianjin Southwest Maritime Ltd. – the Chinese liquefied gas transport operator. The COSCO Shipping Heavy Industry yard (Guangdong) will host the respective conversions of the individual MAN B&W 6G60ME-C engines on board the “Gas Gemini” and “Gas Aquarius” into dual-fuel MAN B&W 6G60ME-LGIP units capable of running on LPG. The two ships will be modernized in parallel, starting May 30, 2023.
In a notable first, PrimeServ will jointly carry out the work with CMS (CSSC Marine Service Co. Ltd.), the aftermarket subsidiary of CSSC Marine Power Group.
Tao Guohua – Vice President, CSSC Marine Power Group – said, “Congratulations to Southwest Maritime on signing the LGIP conversion contract between MAN Energy Solutions and CMS. I am convinced that the emerging engine retrofit market will be a new area for MAN Energy Solutions to strengthen the existing close cooperation between us. We also look forward to building strategic cooperation with MAN Energy Solutions in this market and expanding our cooperation to other portfolios. »
Per Rud – Senior Vice President, MAN PrimeServ – spoke about the importance of developing partnerships to execute successful dual-fuel retrofit projects, and said: “We treat each project on a case-by-case basis, but this particular case is remarkable in that it is the first time that we have collaborated on a renovation project with the after-sales service of an operator. I think it is important for the aftermarket to know that MAN PrimeServ is open to working with all partners to support shipowners around the world. Successful negotiations with CMS have strengthened our partnership and both parties are more than satisfied with the outcome.
The signing of the contract comes on the heels of Oslo-listed BW LPG – the world’s leading owner and operator of LPG vessels – announcing in June 2022 that it had, under the supervision of MAN PrimeServ, converted the main engine of the ‘BW Malacca » in a twin engine. running fuel. The last such conversion for a series of 15 LPG carriers, all work was carried out at the Yiu Lian shipyards in Shenzhen, proof of China’s ability to successfully execute such retrofits.
Klaus Rasmussen, Head of PVU Projects and Sales, MAN PrimeServ, said: “In order to decarbonise the existing marine fleet, switching to low carbon fuel is the most effective tool. In this context, dual-fuel renovations represent a preferred way for owners to maintain the value of their assets for years to come. Specifically, in the case of very large gas carriers, their ability to operate from their own cargo makes a very positive business case. Tianjin Southwest has already ordered six ships powered by ME-LGIP main engines and LPG is on the way to becoming the standard in this segment. Currently, we estimate that there are 154 VLGCs with mono-fuel engine technology that could benefit from conversion to LPG. »
Strong business case Cost-wise, LPG is a better option than compliant fuel oil, with high lifetime savings prospects. By leveraging LPG as a marine fuel, vessels benefit from savings through reduced fuel consumption and full dual-fuel flexibility, which protects against price sensitivity to post-2020 fuel price fluctuations. , the ability to use LPG cargo as an additional fuel source also reduces fuel bunkering time and costs.
Exploiting LPG propulsion also results in cleaner, more efficient and cheaper to maintain engines. Additionally, the energy flexibility of the dual-fuel engines provides full redundancy for uninterrupted operations.
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%.
