RESEARCH AND INNOVATION HOW IT WORKS


The hatch is placed on top of the suction pile and locked in the open position during the lowering process. When the pile reaches the sea bed, a remotely operated vehicle is used to unlock the hatch, close it and lock it shut using an industry-standard torque interface. When closed, the hatch is designed and optimised using finite element analysis to be able to withstand the large installation loads encountered during the suction process which is used to embed the pile.


The hatch is not only capable of coping with external pressure forces, it is also designed to work in reverse, in the event there is a problem during installation or at the end-of-life of the pile when the installation is being decommissioned.

SUCTION PILE VENT SOLUTION


Forum Energy Technologies’ suction pile vent solution attracts offshore wind interest – suction piles offer a quick low-cost method of mooring all sorts of equipment offshore and subsea


Commonly used for mooring vessels and buoyancy tanks on oil & gas installations, they are now being considered for the installation of offshore wind turbines. A key technical challenge encountered during the installation suction pile from its installation vessel is that it must be quickly vented of air and filled with seawater as it is lowered through the splash-zone.


Forum’s suction pile vent hatch offers a rugged, simple to use and low- cost solution to this problem. It has completed extensive qualification processes including hyperbaric testing and has been trusted and proven during hundreds of successful installations worldwide.


EXTENSIVE QUALIFICATION PROCESSES INCLUDING HYPERBARIC TESTING


SUITABILITY


The hatch is available in sizes up to 48” and in a range of materials to suit the particular installation being considered in the field. In the case of critical installations, the hatch can also be supplied with a remediation cover which, in the event of failure, means the installation can still be carried out. The company also supplies an extensive range of hotstabs that are used in the suction process of pumping seawater out of the suction pile.
