Windcat formalised a contract with Damen Shipyards Group on 25 November 2025 for a new Multi-Purpose Accommodation Support Vessel (MP-ASV), initiating the Innovation Series with options for five additional units. The design merges a large open deck, a 150-ton subsea crane, and long-duration accommodation for offshore personnel.
The MP-ASV builds on experience from the Elevation Series CSOVs, yet introduces a larger 102m x 20m platform with 750m² deck capacity and support for ROV deployment. Efficiency upgrades include a 3,981kWh battery system on a DC grid, enabling peak-shaving during DP operations. As with Windcat’s CSOVs, the vessels integrate low-carbon fuels through a dual-fuel hydrogen engine for the auxiliary genset.
Accommodation is arranged for up to 190 people with an endurance of 28 days. Transfers to offshore assets will use a motion-compensated gangway capable of maintaining a fixed link. Interior planning focuses on explicit routing and material quality to support crew well-being.
A DP2+ configuration combines azimuth units with forward and aft tunnel thrusters, preserving DP2 capability if a thruster becomes unavailable—an essential safeguard in remote operations.
Damen Sales Manager Joost van der Weiden highlighted the partnership’s continued progress following the Elevation Series. Windcat Managing Director Willem van der Wel described the MP-ASV as a new vessel class combining MPSV-scale deck capability with ASV-level accommodation.
Construction will begin in February 2026 at Ha Long Shipyard in Vietnam, with delivery planned for 2028.
