Vroegh-edc developed an operations manual for Boskalis in order to launch and recover as well as operating the Boulder Clearance Tool (BCT) from an oceangoing tug making use of the stern roller and towing winches. This operations manual included the step-by-step plans, storyboards, risk analysis, lifting plans, etc.

Removing obstacles (boulders) from the seabed

The BCT is used to clear large boulders and other obstacles from the seabed to create a corridor where in example a power cable for windfarm’s can be installed.
