Cable Lay Vessel(VARD C:V design)
Owner: SEAWAY AIMERY AS · Operator: Subsea7
Also known as: Siem Aimery



Seaway Aimery was built in 2016 by Remontowa Shipbuilding S.A. in Gdańsk, Poland and was originally delivered as Siem Aimery for Siem Offshore Contractors before being renamed under the Seaway brand. Reference material describes it as now owned within the Seaway7/Subsea 7 group, with design documentation noting ownership by Seaway Offshore Cables, and registry data listing the registered owner as SEAWAY AIMERY AS under the United Kingdom flag. Technically, the vessel is a DNV-GL classed cable laying vessel with notation +1A1, Cable Laying Vessel, BIS, DYNPOS-AUTR, COMF(C3, V3), E0, NAUT-(AW) (A), SPS, and is equipped with a DP2 dynamic positioning system. It is 95.3m long with a breadth of 21.5m, carries up to 4,250t of cable on two sheltered electric carousels (2,500t and 1,750t), and has a sheltered cable hangar with workshop and three firing lanes. Key deck and subsea systems include a 5t/10t offshore crane, a 20t AHC A‑frame, electric linear cable engines, and a spread of two work-class ROVs plus an electric trenching ROV, with accommodation for about 60 persons. The vessel is explicitly described as an advanced cable installation, repair and maintenance vessel intended to meet the cable lay demands of offshore wind, renewables and oil & gas industries, with design emphasis on operations in harsh environments. Design notes identify the North Sea as its target area of operations, and recent AIS-based voyage records show frequent calls at Eemshaven and work off the US East Coast, including Revolution Offshore Wind Farm, indicating a focus on offshore wind farm inter-array and export cable projects in both European and North American markets.
The vessel is equipped with four main generator sets driven by MTU main engines, arranged as four main engines each rated 1,840 kW at 1,800 rpm, with the engines and generators mounted on common frames and resiliently mounted. Propulsion and manoeuvring are provided by a total of five Kongsberg thruster/propeller units: two main azimuth propulsion thrusters of 2,200 kW each, one retractable thruster rated 1,200 kW, and two tunnel thrusters rated 1,200 kW each, configured for DP-2 dynamic positioning operations.
