Singapore-based shipping group, Synergy, has successfully converted a 1992-built, 126,000 cu m LNGC into an FSU.

The FSU, which has a projected lifespan of 15 years, was delivered to its owner last week.

Synergy will manage, maintain and operate the FSU on an ongoing basis. The unit will be moored permanently in Myanmar where it will be manned by a Synergy crew of 25 seafarers and receive and store LNG imports for delivery to an onshore regasification plant, which will supply power to local consumers.

“I think this LNG carrier to FSU conversion really drives home that Synergy is not just an asset manager and ship operator,” said Capt Rajesh Unni, CEO and Founder of Synergy Group. “We are a technical thought partner for owners and can deliver integrated solutions which require cross-disciplinary skills.

“We are also now an established single-source technical solution provider of LNG-to-power services. We can take a concept and realise the entire undertaking right through to delivering energy to end consumers even during a global pandemic.

“A lot of our top quality owners already employ Synergy to manage their newbuilding orders in South Korea, Japan and China and we are currently overseeing more than 30 newbuilding vessel projects. This successful conversion shows once again that we are fully equipped to take on the most complex conversions,” he said.


Synergy oversaw the FSU conversion on a one-stop-shop basis, which included identifying the correct LNGC for conversion and selecting a suitable shipyard.

The company also managed the entire design, engineering, procurement and yard oversight process ahead of the FSU delivery and deployment.

The conversion was performed at Sembcorp Marine’s Admiralty Yard in Singapore and included more than 100 tonnes of steel renewal and the cumulative addition of over 1,500 m of cryogenic pipes. Some 25 designers were deployed and the project team consisted of 10 managers overseeing a workforce of some 250 personnel each day.

It was redesigned to offload LNG to the regasification plant at rates of up to 350 cu m per hour during peak demand or 150 cu m during non-peak periods.

Synergy’s newbuilding department is headed by naval architect Subodh Borse, a specialist in LNG newbuilds and retrofits. He said: “Our experienced newbuilding and conversion team is renowned for providing expedited, one-stop, cost effective solutions to clients in the LNG supply chain.

“We were very happy with the design, which includes the addition of four feed pumps in each of the cargo tanks which allows them to hold boil-off gas (BOG) for longer durations. The addition of emergency release couplings and quick release hooks ensures vessels depart the terminal quickly. We increased the tank pressure up to 0.7 bars and the design allows the FSU to simultaneously feed LNG to the regasification plant while also offloading offload LNG to another smaller vessel, ” he said.
