Statoil senior vice-president for operations Astrid Sørensen said: "These contracts, which will involve a long-term cooperation with the chosen suppliers, will result in great savings for Statoil’s logistical operations.

"Logistics represent some 10% of our field costs and making base operations more efficient is essential for extending the lifetime of the fields we operate.

"In addition, Statoil is taking several steps to increase the efficiency of the logistics chain between the coastal bases and our offshore installations.

"We will be achieving considerable economies of scale and synergies by introducing new sailing schedules for the supply of our offshore installations and a greater degree of specialisation at the different bases in the forthcoming contract period."
