6.2 Cargo ships carrying timber deck cargoes
1 A new paragraph 6.2.3 is added after the existing paragraph 6.2.2, as follows:
- "6.2.3 Allowance for ice accretion
- .1 The ice accretion weight, w (kg/m2), may be taken as
follows:
- where:
- ftl = timber and lashing factor = 1.2
- L = length of ship in m
- LFB = freeboard height in mm
- lbow = length of bow flare
region in m, to be taken as the distance from the longitudinal
position at which the maximum breadth occurs on a water line
located 0.5 metres below the freeboard deck at side to the
foremost point of the bow at that waterline.
- .2 The ice accretion weight, w (kg/m2), over the timber deck
region should be applied to each of the load cases as illustrated in
figure 1:
