40、neral principles4.1 Provision and overall design of fendering systemsBerths should be provided with a suitable fendering system to protect berthstructures and vessels from damage, taking into account operating conditions asdefined in BS 6349-1-1:2013 and stated in the facility operating manual, unle
41、ss aclear justification can be made that such a system is not required.NOTE 1 Historically it has been the practice in some ports not to provide fenderingto berths other than simple timber rubbing strips, particularly where they aresituated in sheltered locations such as impounded dock basins. For c
42、ommercialvessels, and where berths are situated in more exposed locations such as the outerreaches of rivers and in the open sea, fendering systems are widespread.The fendering system should be designed taking account of:a) the range of vessels berthing;b) the methods used to berth the vessel;NOTE 2
43、 Where a vessel berthing alongside is manoeuvred by tugs and/or theuse of thrusters, it is generally stopped a short distance off and parallel to theberth. The vessel is then pushed or warped slowly onto the berth, ideallyachieving a gentle contact as near as parallel to the berthing line as possibl
44、e.NOTE 3 Tugs, launches and other small vessels tend to approach their berthsmore directly than large vessels.NOTE 4 Ferries and roll-on/roll-off (Ro-Ro) vessels approach their berths in adifferent way, which is explained in 4.5.2.c) vessels moored during cargo handling operations;d) vessels moored
45、during extreme events caused by adverse metocean or otherconditions;e) the normal operating conditions of the berth;f) the risks and consequences as a result of an extreme or accidental eventoccurring;g) the features appropriate to the location of the berth, as shown in Table 1;h) the features appro
46、priate to the characteristics of the vessels that areexpected to use the berth, as shown in Table 2;i) the intended service life of the system, making due allowance fordegradation and wear and tear during operations.NOTE 5 The fendering system might need to be designed to work with themooring system
47、 to reduce vessel movements.NOTE 6 Fendering systems are required to be suitable for all operational waterlevels that might occur, and with large variations this becomes particularlyimportant. Winds, waves, current and other factors also vary depending on the berthlocation.BRITISH STANDARDBS 6349-4:
