The Sea Helix 1 is classed as a Well Intervention Vessel (WIV) and can operate in up to 3,000 m of water with a transit speed of more than 15 kn, capable of providing service quickly and efficiently where needed.
The vessel can complete a wide range of subsea projects, including well intervention; well decommissioning; top hole drilling; subsea installation work; offshore crane and ROV operations; offshore construction work; and emergency response capabilities.
Combining exceptional operational capabilities with excellent performance and stationkeeping, the vessel helps optimize through-tubing well interventions. It incorporates the latest technology in testing, handling, deploying, operating, and retrieving the intervention riser system and associated well services.
The Sea Helix 1 can operate in up to 3,000 m of water, and with a transit speed of over 15 knots, it is capable of providing service quickly and efficiently where required. It provides a cost-effective, readily mobilized alternative to mobile offshore drilling units (MODUs) for intervention and abandonment. The vessel is equipped with two 200-hp Triton XLX work-class ROVs (WROVs) and high-sea-state launch and recovery system controls.
Helix’s comprehensive range of services enables our customers to safely access offshore wells to perform production enhancement or decommissioning operations. In addition, we can integrate and operate Helix Intervention Riser Systems (IRS) or client supplied subsea well intervention packages.
