2.2.2 The operators are to confirm to the Surveyor that vessels utilizing the linkspan do not exceed the maximum displacement or berthing speed and approach angles specified in the current approval. Operators are to provide evidence that the maximum displacement and approach speeds/angles have been communicated to the users of the installation.

2.2.3 The mooring or tethering arrangements are to be examined, as far as practicable, for all linkspans that have been assigned the class character symbol T.

2.2.4 The Surveyor is to confirm that, where provided, fendering arrangements continue to remain efficient.
