Abstract:
1. An anchor line pretensioning method comprising the steps of: connecting a first end of a first anchor line and a first end of a tensioning line to the seabed at respective first and second anchoring points, said first anchor line and said tensioning line being at respective opposite first and second sides of an installation vessel; connecting a second end of the first anchor line and a second end of the tensioning line to the installation vessel, at least one of said first anchor line and said tensioning line being connected to a tensioning device on the installation vessel; connecting a second anchor line to the seabed at a third anchoring point spaced at a distance from the first anchoring point and to the installation vessel at said first side of the installation vessel; mutually connecting the first and second anchor lines via a connecting member, said connecting member being attached to the installation vessel; and exerting a pull force on the connecting member, the pull force being oriented in a direction of the tensioning line such that the first and second anchor lines are pulled substantially along their theoretical routes away from the first and third anchoring points, wherein the connecting member comprises a generally triangularly shaped plate.
