from an MAN B&W 6G60ME-C9.2 type to an MAN B&W 6G60ME- LGIP dual-fuel type capable of operating on fuel oil and LPG. The BW Gemini is part of the fleet of Oslo-listed BW LPG, the world's leading owner and operator of LPG vessels. The successful conversion and start of gas and sea trials will make the BW Gemini the world’s first commercial vessel to be propelled by a two-stroke LPG dual-fuel engine. The conversion is the first of 12 ordered by BW LPG for a series of vessels in its fleet.
MAN Energy Solutions announced the first four BW LPG retrofit orders for its new MAN B&W ME-LGIP LGP-powered engine in September 2018 in advance of the official launch of the engine at its Research Centre Copenhagen, and exchanged the contract publically with BW LPG during the event.
Subsequently, in February 2020, the type approval/parent engine test was performed at licensee STX works in Korea with the TAT approved by all classification societies.
The BW Gemini docked at Yui Lian Ship Yard in Shenzen, China in early August 2020 for conversion. Due to pandemic restrictions, the MAN PrimeServ project team collaborated in great part remotely to push the conversion forwards.
Sea trials are scheduled for October 2020 with the LPG carrier due to re-enter commercial trading upon their successful completion.
