20、n vessels Studless anchor chain Accessories 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 14606 and the following apply. 3.1 chain locker compartment where the anchor chain is stored 3.2 end fastening fastening of the anchor chain to the vessel 3.3
21、chain stopper device connected to the vessel, separate from the chain lifter, for holding the anchor chain when the windlass is released 4 Safety requirements 4.1 Chain locker The chain locker shall accommodate the whole length of the anchor chain as it comes to rest in the chain locker without any
22、outside aid. Each chain shall have its own chain locker. The chain length and size are based on the national specifications as a function of the area of travel and vessel size. If no data are available, some calculation aids are given in Annex B. It shall be possible to store the anchor chain in the
23、 chain locker, e.g. on a perforated plate, so that water and solid material cannot be deposited there. 4.2 End fastening The anchor chain fastening to the vessel shall be easily accessible in the event of an emergency and be detachable safely and in a controlled manner with a simple tool. EN 15271:2
24、007 (E) 5 A slip hook as shown in Figure A.1 is suitable, for example. It shall be possible to knock out a bolt, if necessary fitted with a split pin, or a wedge, see Figure A.2. Bolted connections or bolted shackles are not permissible. The strength of the end fastening shall be such that it is cap
25、able of withstanding a minimum breaking load 20 % greater than that of the anchor chain according to EN 14330. No permanent deformation of the chain end fastening is permitted in this case. The substructure of the vessel shall have the same strength at least as the end fastening. 4.3 Chain stopper T
26、he chain stopper shall lock the anchor chain when the vessel is lying at anchor or the anchor is raised. Handling the chain stopper shall be simple and safe for the operator. With hand-operated chain stoppers, the manual force required to unlock the unloaded chain shall not exceed 350 N. Chain stopp
27、ers and, in particular, the locking element shall be designed so that the anchor chain held in the chain stopper is not damaged when loaded with 80 % of its production test load, e.g. by indentations. They shall remain fully functional afterwards, see example in A.3. 5 Material Materials for chain s
28、toppers shall have at least the mechanical characteristics of the round steel link chain as specified in EN 14330. Grey cast iron materials are not suitable for chain end fastenings or chain stoppers. 6 Manufacturers certificate The manufacturer shall declare conformity of the components to this sta

37、d according to equation (B.1): P = k B T (B.1) Where: P is the total mass of the anchor, in kg; B is the width of the vessel, in m; T is the draught of the vessel, in m; k is the coefficient that takes account of the ratio of L and B and the type of vessel: B8 Lck = (B.2) c is the coefficient accord
38、ing to Table B.1, for lighters, however, k = c; L is the length of the vessel, in m.

39、 pushers, shall be equipped with bower anchors of total mass P in kg to be calculated according to equation (B.1). For passenger vessels intended to operate below Rhine kilometre 885 (Emmerich), however, the total mass P shall be calculated according to equation (B.3) taking into account the surface
40、 exposed to wind: P = k B T + 4 A1 (B.3) Where: k is the coefficient according to B.1, but when determining coefficient c the displacement in m recorded in the vessel certificate shall be used instead of the deadweight-carrying capacity; A1 is the frontal surface exposed to the wind in m2. EN 15271:
41、2007 (E) 12 B.3 Vessels according to B.1 shall be equipped with stern anchors of total mass 25 % of mass P. Vessels with L greater than 86 m, however, shall be equipped with stern anchors of total mass 50 % of mass P according to B.1 or B.2. B.4 Anchor masses determined according to B.1 to B.3 may b
42、e reduced for certain special anchors. The total mass P specified for bower anchors may be distributed between one or two anchors. It may be reduced by 15 % if the vessel is equipped with only one bower anchor and the hawse hole is located in the centre-line plane. B.5 Bower anchor chains shall have
43、 the following minimum lengths: a) 40 m for vessels with L not exceeding 30 m; b) 10 m more than L, if L is between 30 m and 50 m; c) 80 m for vessels with L exceeding 50 m. Chains of the stern anchors shall each be at least 40 m long. However, vessels that have to be able to stop with the bow downs
44、tream shall have stern anchor chains each at least 60 m long. B.6 The minimum breaking load R of an anchor chain shall be calculated according to the following equations: a) for anchors of mass up to 500 kg: R = 0,35 P kN; (B.4) b) for anchors of mass over 500 kg to 2 000 kg: R = ;kNP00015 500P0,35
45、(B.5) c) for anchors of mass over 2 000 kg: R = 0,25 square2 P kN (B.6) Where: R is the required minimum breaking load of the anchor chain in kN; P is the theoretical mass of the individual anchor determined according to B.1 to B.3 and B.4. The breaking load of the anchor chains shall be taken from
46、EN 14330. If heavier anchors are selected than result from B.1 to B.4, the minimum breaking load of the anchor chain shall be determined in accordance with the larger mass available.
