New fleet of LNG-powered prime movers begin operations at PSA Singapore


A new fleet of 80 Liquefied Natural Gas (LNG) prime movers have begun operations at PSA Singapore’s Pasir Panjang Terminal.

The prime movers have a tank capacity of around 130kg – meaning each machine can operate for more than 20 hours before refuelling.

Despite some in industry questioning the viability of LNG’s future in maritime, LNG is a cleaner fuel for prime movers compared to diesel.

The alternative fuel burns with lower carbon dioxide emissions, as well as reducing the emissions of pollutants such as nitrogen oxides, sulphur oxides, and particulate matter.

Since their deployment, LNG prime movers have allowed PSA Singapore to reduce its carbon dioxide equivalent (CO2e) emission from prime movers by an estimated 20%.

The new machines will join Singapore’s first LNG refuelling station, opened in April 2021.

The station has four dispensers and a capacity of 40 tonnes, allowing some 300 LNG prime movers to be refueled daily.

The station’s design ensures capture of any LNG vapour that may have been leaked during the refuelling process, recovering and recycling the vapour back into storage tanks.

PSA Singapore will continue to take delivery of more LNG prime movers throughout 2021, with 160 LNG prime movers to be deployed in Pasir Panjang Terminal by the end of August 2021.

When fully deployed, the LNG prime movers are projected to reduce some 4,000 tonnes of CO2 per year compared to diesel prime movers.

PSA Singapore aims to cut its greenhouse gas emissions by 50% from 2019 levels by 2030.
