Overview
Built in 2003 and flagged in the Marshall Islands, *SubCom Resolute* is a mid-sized cable ship operated by SubCom, one of the principal contractors in the submarine cable industry. At 139.1 metres in length with a 21-metre beam and a gross tonnage of 12,184, the vessel is sized for demanding deepwater work across both new-build projects and live-network maintenance.
What the Ship Does
Resolute carries up to 5,465. 5 tonnes of cable coiled into below-deck tanks — enough to lay or repair substantial spans of submarine system. On installation work, cable is paid out over the stern as the ship moves along a surveyed route, with burial depth and seabed contact managed by the equipment aboard.
On repair voyages, the ship locates a fault, recovers the damaged cable section, and technicians splice in a replacement length before returning the system to service.
Equipment and Positioning
The ship is fitted with a sea plough capable of burying cable at either 1. 5 or 3 metres beneath the seabed — deeper burial offering greater protection in shallower, higher-risk zones such as shipping anchorages and fishing grounds. Where a plough cannot operate, a cable-trenching ROV (remotely operated vehicle) takes over, working to depths of 2,500 metres without requiring the ship to be directly overhead.
Cable handling is managed by one 16-tonne linear engine and two 4. 0-metre drum engines, giving the crew fine control over tension during both lay and recovery operations.
Dynamic positioning to DP2 standard — a classification requiring redundant propulsion and power systems so the vessel holds station automatically even if a single component fails — allows precise work over splice sites without anchoring.
Fleet Context
As a dual-role vessel, Resolute sits at the practical centre of SubCom's operational fleet, deployable on new cable contracts or redirected to emergency repair work as demand requires. Its base port is not publicly documented.
