Norwegian offshore vessel operator DOF Group ASA has secured an extension to the Skandi Mariner contract, keeping the anchor handling tug supply (AHTS) vessel under firm contract through the third quarter of 2028.

The extension follows the exercise of an option under the vessel’s existing agreement, which had previously been scheduled to expire in the second quarter of 2027.

In a statement issued on 9 November 2026, DOF classified the value of the extension period as Significant, a category the company defines as covering contracts worth between USD 15 million and USD 25 million.

The disclosed value range applies only to the additional contract period, rather than the full duration of the existing agreement. DOF did not specify the exact extension value, the client or the vessel’s operating region.

The option exercise secures continued contractual employment for Skandi Mariner beyond its previously scheduled expiry, extending the AHTS vessel’s firm contract coverage into the second half of 2028.
