Section 3 General installation requirements

Parent topic: Chapter 14 Foundations

3.1 General installation requirements

3.1.1 Details of the proposed method of anchor and anchor line installation are to be submitted.

3.1.2 Except where stated, anchors are not required to be test loaded at installation. However, for catenary mooring systems preloading of the anchor line is to be performed to ensure its alignment through the seabed and to minimise in-service anchor line slack.

3.1.3 Visual surveys of the seabed are to be performed at the proposed anchor point locations immediately prior to installation. The visual survey should provide confirmation that the anchor point locations and immediate surrounding area are free of any other seabed obstacles or obstructions that may have appeared in the period since the geophysical survey was performed.

3.1.4 Design installation tolerances shall be included in the installation philosophy and where tolerances are not met further confirmation of anchor suitability should be provided. Anchor approval shall be based upon demonstration that the anchors remain suitable.
