Daewoo Shipbuilding and Marine Engineering (DSME) has engaged TMC Compressors to supply a marine compressed air system for four newbuild LNG vessels the South Korean shipbuilder is constructing for BW LNG
TMC’s Smart Air compressors are based on a frequency-controlled technology that offers precise control of the compressor speed.
The company said the speed of the electrical motor adjusts itself according to what is required to produce the exact air volume necessary to meet the actual compressed air consumption at all times. In turn, lower air consumption requires less speed on the compressor, and this directly results in less power consumption.
According to BW LNG, the new vessels feature a low profile fuel consumption with ME-GI propulsion, a full reliquefaction system, air lubrification system and shaft generators.
“When you look at the environmental profile of the four LNG vessels, with BW LNG investing in enabling the lowest possible fuel consumption, emissions and operating costs, we are proud DSME opted to go for our Smart Air compressors. The various fuel-reducing technologies are a great match for each other,” said TMC international sales manager, Jens Erik Tøstad.
The Norway-based manufacturer claims the Smart Air compressors can offer up to 40% energy savings compared with conventional compressors. The system will consist of control and service air compressors.
TMC will manufacture, assemble and test the equipment in Europe and ship it to DSME in South Korea. DSME will deliver the four 174,000m3 LNG carriers in 2025.
