ABSTRACT:

This invention relates to a system for mooring ships, in particular for operations in connection with oil and gas activity, whereby the ships concerned are equipped with mooring means at their bow part, and where there is included anchor means located at the seabed, as well as at least one achoring line adapted to connect the anchor means to the mooring means on the ship.
In offshore oil and gas activity there is often the question of very important operations that can be difficult under certain conditions, and whereby there is usually involved transfer of fluids either between two ships, of which one can be moored, or between a pipeline connected to the anchor means at the seabed and a moored ship. Under varying and difficult conditions, whereby wind, waves and ocean current have influence, great stresses and forces can occur during such mooring and carrying out of these operations. Such stresses in the first place can lead to interruption of the operations and in the worst case can lead to wrecking and e.g. uncontrolled oil discharge. It is obvious that the system according to the invention depending on the circumstances, can also be utilized for other types of operations at sea, than in connection with oil and gas activity.
On the background of mooring systems being known for corresponding purposes, this invention involves novel and specific features as stated more closely in the claims.
Among the advantages obtained by means of the invention, it is emphasized in particular that the challenging operations mentioned, can be carried out under difficult conditions with higher security and reliability in most situations, compared to previously known methods and systems. In this connection it is to be noted in particular that the system according to the invention makes possible a type of elasticity or flexibility in the mooring and possibly the fluid transfer, that involves adaptation of the whole system according to the stresses and forces occurring during the operations to be performed.
