-Beluga is a deepwater post-lay trenching machine, designed for pipeline trenching upto a maximum slope angle of 40°, in water depths ranging from 10m to 2200m. Trenching is performed by two “up-milling” cutting discs, promoting trenching in soils varying from very soft clays to 30MPa clay-stone. Trench clearance is via two retracted
impeller pumps, capable of managing cobbles without risk of damage.

-The trench width angle and deployment of the cutting discs are individually adjustable, enabling multi-pass deep trench formation. A trench depth of 1.5m can be achieved in a single pass, and a maximum trench depth of 5.1m is achievable by multi-pass. Beluga is a technological development of the successful Giano™ system, aspects of its key operating features have been optimised to enhance the Beluga performance.

-The trencher is free-swimming (neutrally buoyant) allowing independent, controlled attachment to the pipeline with minimal risk of damage. Once attached to the pipeline the Beluga propels itself using eight polyurethane-coated rollers capable of overcoming anodes and buckle arrestors. Pipeline safety features are included in all aspects of Beluga operations.



We try to provide the most up to date, recent specifications on these ROV systems. However, ROV system specifications are changing all the time, so please double check with the manufacturer to insure the specifications are correct before making a decision in using or purchasing these systems.
