To support BP's strategy to grow our gas portfolio, BP Shipping has introduced a new fleet of liquefied natural gas (LNG) ships, the most fuel-efficient and technically advanced LNG tankers ever built for BP. They will help us to respond to growing demand for gas in both established markets, such as India, China and the US, and new markets, such as Pakistan, Jordan and Bangladesh.
The ships are fitted with 'slow speed' tri-fuel engines, which can use compressed 'boil-off' gas from the cargo tanks as fuel. Boil off is the liquid LNG changing state to gas due to slight temperature rise during transportation which can then be used to power the engine.
This technologically advanced engine is around 25% more fuel efficient than those fitted in the older LNG ships in the BP fleet. It also has a thermal efficiency of around 52%, making it one of the most efficient engines available, reducing carbon dioxide, nitrogen oxide, sulphur dioxide and particulate emissions in normal operating conditions. The vessels are fitted with compressors as part of the fuel system, that can also be used to run a reliquification plant, condensing and saving gas that would otherwise have to be flared.
