Dutch subsea solutions provider the N-Sea Group is set to welcome a new shallow-draught installation vessel to its fleet by the second quarter of 2026.
Named Altera, the DP2 vessel will be methanol-ready and dual fuel-capable and will be equipped with a 25-tonne offshore knuckle boom crane and mooring system. Accommodation will be available for up to 99 people.
The vessel is under construction in Poland and will be transferred to the Netherlands in Q4 2025 for fitting and commissioning.
The deck spread designed and procured by N-Sea will consist of 4,500-tonne carousel, a 15-tonne tensioner, a quadrant handling system and shutes designed to handle cables with a minimum bending radius of just under five metres. Installation of the deck spread will start in Q1 2026 by the N-Sea mobilisation team in the Netherlands.
N-Sea said that, due to the combination of its mooring system, DP2 capabilities and beaching capacities, the vessel will be able to operate year-round in both very shallow and deep water conditions, on interconnector, export and inter-array cable projects.
