Atlas Copco Gas and Process has been selected to provide oil-free compressor technology to feed modern LNG carriers.

Drawing from its large experience serving the LNG market, turbomachinery manufacturer Atlas Copco Gas and Process Division has secured a breakthrough compressor order for the carrier LNG market.

The order – placed by Samsung Heavy Industries in Korea – is for a total of eight HD centrifugal gas compressors, eight oil-free gas screw compressors along with the necessary heaters and vaporisers. The equipment will be used on four 180,000 m3 vessels commissioned by Celsius Tankers. The first units will begin shipping from Atlas Copco Gas and Process to the customer beginning October 2019, with the remainder of the machinery to be delivered in the second quarter of 2020.

The new vessels will utilise Atlas Copco’s new oil-free gas screw compressors to feed their XDF engines - a first in the Carrier LNG industry. This new compressor technology was specifically designed to meet modern carrier needs, including the XDF pressure requirements and reduced flow of boil-off gas from improved insulation measures. The oilfree design also allows for significantly longer maintenance intervals compared to oil flooded  compressors and can be used with a reliquefaction system without any risk of oil contamination in heat exchangers or LNG cargo.

“This order is a milestone in our marine LNG product development. To be able to provide the first ever oil-free gas screw compression technology for carrier vessels is a significant step in the evolution of our products,” said Robert Radimeczky, president of the Gas and Process Division.
