Derelict Fishing Net Removal
October , 2015
Over 5,600 derelict fishing nets had been removed from Puget Sound water by volunteer divers from depths up to 105 feet. Yet there remains many more in deeper water. Global Diving, working with Natural Resources Consultants for the Northwest Straits Foundation developed custom tooling and a ‘plan’ to remove the nets using a SAAB Cougar and Falcon ROV. First the ROV’s surveyed the nets, then a plan was developed, utilizing the tooling to gather and cut the nets free from the obstacles they snagged on. Once gathered and free, they were connected to the line from a vessel mounted crane. The balls of net were raised to the surface for proper disposal.
This pilot program was developed to test the feasibility and develop the tools and methods required for this removal.
