TMC Compressors has secured a contract from Hyundai Heavy Industries (HHI) to supply marine air lubrication system compressors to three LNG carriers that the Korean shipbuilder is constructing for Pan Ocean.

ALS reduces the resistance between the ship’s hull and seawater by using air bubbles. The air bubble distribution across the hull surface reduces the frictional resistance on the ship’s hull and results and facilitates energy savings.

TMC has developed a range of frequency-controlled marine compressors for use with air lubrication systems to help ships further reduce fuel consumption and emissions to air.

Each of three LNG carriers will be equipped with three ALS compressors from TMC. The ALS compressors will then be coupled with HHI’s Hi-ALS system.

‘ALS is about reducing fuel consumption, energy costs and emissions to air. It is a great way of reducing the shipping industry’s environmental footprint while also reducing shipowners’ OPEX,’ said Hans Petter Tanum, TMC’s director of sales and business development.

According to TMC, frequency-controlled ALS compressors also offer fuel savings compared to conventional compressors. As the frequency-controlled technology offers precise control of the compressor speed, the speed of the electrical motor will adjust 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.

The equipment will be manufactured in Scandinavia and shipped to Hyundai Heavy Industries in Korea.
