Mass flow excavator refurbished and set to work on power cable projectVessel & ROV News // January 21, 2016
After a four week refurbishment of its recently acquired SeaVex, Pharos Offshore says it currently has a team of seven personnel manning the mass flow excavator.
SeaVex is based on a hybrid subsea excavation system which is extremely adaptable, compact and controllable.
The equipment houses a large single cast impellor complete with direct drive and torque restrictor driven by a powerful compact hydraulic motor. Fitted with adjustable sized outlet nozzles at the base of the tool it allows enhanced kPa cutting of a comprehensive range of seabed materials. Each system is fitted with a Narrow Beam Imager for live monitoring of operations.
SeaVex, currently on-board DPV Supporter, will be burying a live power cable section of 100m to a depth of 4m in the Estuary of the River Weser, Germany. The system was prepared and shipped in five days.
