5.5 External environment
The transport of LPG and petrochemical gases by sea entails little risk of emissions or leakage into the sea. Loading and unloading operations are conducted in closed systems, and strict quality and safety requirements reduce the risk of emissions to a minimum.
All transport at sea entails emissions to the air from the combustion of oil by the ships’ main and auxiliary engines. Our policy in this area is thus to reduce such emissions as much as practically possible. The group focuses primarily on reducing the consumption of bunkers and lubricants, and has through active measures been able to continue the positive trend achieved in recent years. The modern ships today use up to 40% less fuel compared to ships of same size 20 years ago.
Measurements are carried out regularly using a number of systems. Fuel consumption measured against the distance travelled is one of the most important key figures. Wherever possible, we optimise our speed, in other words the speed that gives the lowest emissions and consumption given the contractual obligations we have towards our customers. These systematic analyses have generated excellent results in only a short timeframe. Our modern fleet is also significantly more environmentally friendly than older ships.
In 2010, the company was certified and approved in accordance with the ISO 14001 environmental standard, and will continue in its work to comply with the standard in future.
