how it works
During installation, the hatch is secured in opened position. After suction anchor landing and self-penetration, the ROV will remove the securing mechanism. Thehatch then closes by freefalling. The ROV will operate the handles to closed positions.
During suction anchor retrieval the suction hatch will be opened when the suction anchor is ready to be lifted out of the ground. The operation handles will be released, and the hatch is rotated with the assistance of a lift wire to surface.
