Buoyancy repair

At MarLog we have considerable experience with repairs of surface and subsea buoys. We offer a repair program for the complete range of buoys we deliver. Before starting the project, we will inspect the buoys to establish how sever the damage is, and however it will be economically viable for the owner to repair, or we recommended changing the unit.
