AGR strengthens marine spread with additional vessel capacity

The company said the addition of the vessel to the fleet it controls strengthens its marine spread, supporting growing North Sea activity including subsea operations, plug and abandonment (P&A), cable campaigns and decommissioning.

AGR business development and project manager Karl Kristian Hasselø said, “With AHTS rates accelerating across Northern Europe, the addition of Aquaman II to our vessel portfolio allows us to provide competitive vessel and marine campaigns, providing clients with forward flexibility and operational readiness in an increasingly constrained vessel market.”

“Securing capacity such as Aquaman II strengthens our ability to deliver offshore marine campaigns with greater predictability and flexibility,” said Mr Hasselø. “By integrating vessel capacity into our P&A and decom delivery model, we reduce interfaces, improve decision making, and lower overall project risk for our clients, even under tight market conditions.”

AGR said the converted vessel “provides a flexible and cost-effective alternative to heavier construction tonnage, particularly suited for campaigns where operability, schedule certainty, and cost control are critical.”

Aquaman II will be configured as a ‘light construction-AHTS’ (CAHTS), equipped to support P&A, wellhead severance, cable operations and decommissioning scopes. The vessel is owned by Star Matrix Ltd and will be operated by AGR.

The vessel retains its original towing and anchor-handling capabilities, and is equipped with a work-class ROV, subsea and active heave compensation system to support efficient subsea operations. Built in 2005, Aquaman II is 89.3 m long with a beam of 20.6 m and a deck area of 755 m2. The deck cargo capacity is 2,100 tonnes.

AGR already operates a fleet of two chartered vessels, Ross Eagle and Sunny Lady. The vessels support site surveys, towing, subsea operations, vessel-based P&A, and decommissioning for offshore and wind infrastructure projects.

AGR’s marine, vessel-based subsea and offshore survey execution capability stems from the acquisition of Ross Offshore in 2024.
