Norway's Eidesvik Offshore believes its pioneering work on eco-ships will help it turn around results in tough offshore support vessel (OSV) markets.

In its fourth quarter results statement, the OSV owner said its oil and gas clients have been affected by an accelerating global shift away from fossil fuels.

Investors and other capital sources are demanding that companies in the sector take action and implement initiatives that will reduce each company's impact on the climate, the company added.
