For the test suction bucket jacket of Borkum Riffgrund I, Ørsted (Dong), and DEME required a seafastening solution. This seafastening would serve as a solid example for future suction bucket jacket seafastening operations.
TWD designed an innovative and operation-friendly structure that claps the suction buckets to the deck. The relatively thin buckets were clamped by utilizing pre-tensioned threaded bars in order to avoid welding or difficult accessible lashing. To prevent the buckets from getting damaged, the clamps were outfitted with a wooden interface. This seafastening structure has brought many tangible benefits, resulting in a more efficient and cheaper installation process.
