Jacket Seafastening â€“ Borkum Riffgrund
An innovative structure for the future suction bucket jacket seafastenings
For the test suction bucket jacket of Borkum Riffgrund I, Ã˜rsted (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 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.
Our close partnership with DEME and Ã˜rsted (Dong) successfully installed the Borkum Riffgrund wind farm (277 MW) that currently supplies green energy to 320.000 homes per year.
