AGR, a multidisciplinary consultancy specialising in wells, reservoirs, marine and subsea solutions, has entered into a partnership agreement to onboard the multipurpose offshore support vessel Aquaman II. This addition strengthens AGR’s marine spread, supporting growing North Sea activity across vessel-based subsea operations, plug and abandonment (P&A), cable campaigns, and decommissioning.
AGR’s marine, vessel-based subsea and offshore survey execution capability stems from the acquisition of Ross Offshore in 2024.
AGR’s approach to P&A and decommissioning entails an end-to-end delivery model that integrates well engineering and well abandonment, cost management, vessel provision, and offshore execution within a single, coordinated framework, enabling efficient mobilisation and scalable execution aligned with project activity.
“With AHTS rates accelerating across Northern Europe, the addition of Aquaman II to our vessel portfolio allows us to offer competitive vessel and marine campaigns, providing clients with forward flexibility and operational readiness in an increasingly constrained vessel market,” says Karl Kristian Hasselø, business development and project manager at AGR’s marine division.
Aquaman II
The Aquaman II will be configured as a light Construction-AHTS (CAHTS), well-equipped to support demanding 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 (AHC) system to support efficient subsea operations.
Built in 2005, Aquaman II is 89.3 metres long and 20.6 metres wide, with a deck area of 755 square metres and a deck cargo capacity of 2,100 tonnes.
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.
“Securing capacity such as Aquaman II strengthens our ability to deliver offshore marine campaigns with greater predictability and flexibility. 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,” adds Hasselø.
AGR’s Marine and Subsea Solutions
AGR already operates a fleet of two chartered vessels, the Ross Eagle and Sunny Lady. These support site surveys, towing, subsea operations, vessel-based P&A, and decommissioning for offshore and wind infrastructure projects.
AGR is part of Oslo-listed consultancy group ABL Group ASA.
