Rever Offshore says it has extended its charter of a dive support vessel (DSV) from Norwegian owners Volstad Maritime.

The UK-based subsea company said it had taken the Rever Topaz (built 2007) for another three years. Financial terms were not disclosed.

Rever said the contract will see it secure “exclusive and uninterrupted access” to the asset until December 2022, with “flexible options” to further extend the charter to the end of 2025.
