Seabed Site Clearance & Subsea Construction


Helix provides solutions for seabed site clearance, subsea preparation, pre-construction, and construction services with a highly versatile fleet of assets.

Designed to support offshore energy and wind farm construction, the i-ROV tool is essential for site preparation, UXO/MEC identification and disposal, and boulder relocation. As the demand for offshore renewables grows, this cost-effective tool efficiently addresses subsea clearance challenges.

The i-ROV features customizable grabs for boulder relocation, handling up to 20-tonne boulders. It offers flexibility for various offshore operations, with smaller grabs there is a mobilized launch and recovery system, where the larger grabs require a crane-equipped vessel which Helix also operates. This adaptability ensures efficient project execution.

Equipped with advanced sensors, thrusters, and sonar, the i-ROV enables precise subsea operations. Operated by a skilled team, it ensures the safe and effective execution of subsea tasks, supporting the continued growth of offshore renewable energy projects. Operated by a team of experienced ROV pilots and technicians, the i-ROV ensures that subsea tasks are completed safely and effectively, supporting the responsible development of offshore renewable energy projects and contributing to the global energy transition.
