1.3 Objective

1.3.1 Each buoyant linkspan is to be secured on station by a mooring system or tethering arrangement that is able to adequately and efficiently resist environmental, operational and berthing forces applied to the linkspan.

1.3.2 The mooring system or tethering arrangement adopted is also to accommodate the full tidal range possible at the location without restricting the vertical movement of the linkspan due to the rise and fall of the tide.
