As COP26 continues, we are publishing some of the great advances we have made in the area of sustainability, our first feature is on our Marine offerings which can reduce CO2 emissions by up to 38,000 tonnes every year.

The Marine industry faces a significant challenge to improve environmental emissions and transition to a lower carbon future. The industry target is to reduce emissions by 50% by 2050.

To support our customers in meeting this environmental goal, without sacrificing speed, we have developed a hull air lubrication system, built around our HV-Turbo compressors, which reduces the friction between the vessel and the water giving significant fuel efficiency gain of 7–10%. A typical commercial vessel uses around 400 tonnes of fuel oil a day.

The technology is based on blowing air under the hull of the vessel creating a carpet of bubbles. The air bubbles’ distribution across the hull surface reduces the resistance generated between the ship’s hull and the water.

Air lubrication systems can be used in all types of vessel operations, and can be retro – fitted to existing vessels. For every tonne of fuel we avoid using, we also reduce the harmful SO2 emissions from the fuel oil.

Environmental Benefits

Cuts fuel consumption by 7–10 %.

Reduces CO2 emissions by up to 129 tonnes a day or 38,000 tonnes a year.

Also contributes to SO2 reduction.
