Foundation installation

The monopile has been the most commonly used foundation type for offshore wind farms. As projects move futher offshore into deeper water monopiles are becoming larger in terms of length and diameter and consequently weights are increasing significantly. The powerful heavy lift crane onboard SEA JACK is the ideal tool for handling these huge steel tubes. 

Whilst having the right equipment is important, it is the know-how of A2SEA’s employees that is critical in successfully planning and implementing the complex upending and lifting procedures. A2SEA is able to design and install the deck spread and sea-fastening to ensure that monopiles and transition pieces are securely stowed on board for transfer from the logistics harbour to the offshore site. We also offer a full lifting design and supervision service that meets the demanding requirements of the BS7121 standard.

New foundation designs are also being developed as the industry evolves and projects move into even deeper water. SEA JACK is also capable of handling jacket and tripod foundations and A2SEA has recently been involved in the trial installation of a new suction bucket foundation design. Safety and precision is critical when lifting large, heavy structures and our dedicated team of lifting supervisors will ensure that those key criteria are met.
