In addition, the metacentric height for floating establishments under option A (see 4.4) under impacts as per A.5 to A.7 and A.11 shall be at least 0,15 m. For these structures, heeling motions caused by the vessel’s movement or by the mooring equipment as well as open areas of liquid, which occur during the
operation of the floating establishment, shall also be taken into consideration. Intact stability shall be tested as specified in 7.3.1. 4.3.3 Damaged stability
It shall be ensured that the floating establishment will neither sink nor capsize in the case, that one air chamber is damaged. In this case, a residual freeboard and a residual safety distance each of not less than 10 cm shall be maintained; if greater residual safety distances or residual freeboards are required by the specifics of the waterway, these shall be taken into account. Free surfaces of liquids that can occur during operation shall also be taken into account. If all buoyancy bodies are completely flled with a material according to 4.5.4, proof of leak stability may be omitted. Damage stability shall be tested as specified in 7.3.2. 4.4 Anchorages for floating establishments Floating establishments shall be anchored in their positions to prevent them from being torn loose or being displaced by currents, wind, waves, fluctuations in water level or the draught or wash of passing vessels or possible special loads. In the case of floating landing stages, the influence of berthing ships shall also be taken into consideration. The functioning capability of the anchoring of the floating establishment shall also be proven for the case that the floating body of the floating establishment springs a leak.Taking into account 4.3, for floating landing stages the height difference between the traffic areas of the floating body and the deck of the vessel shall be as small as possible for the berthing vessels expected. For floating bridges the height of the traffic areas of the floating body shall be selected taking 4.3 into account, so that no waves enter the traffic areas under predictable wind and wave conditions.BS EN 14504 pdf download.
