35.3 Sea Inlet Chests for Cooling Water Systems and Fire Main (1995)
The sea water system is to be designed to ensure a supply of water for the cooling water system and
for at least one of the fire pumps when navigating in ice. For this purpose, at least one sea water inlet
chest is to be arranged as follows.
35.3.1
The sea inlet is to be situated near the centerline of the vessel and well aft, if possible.
35.3.2
The sea chest volume is to be on the order of 1 cubic meter (35.3 cubic foot) for every
750 kW (1033 mhp; 1019 hp) propulsion engine output including the ship’s service auxiliary
engine output.
35.3.3
The sea chest is to be sufficiently high to allow ice to accumulate above the inlet pipe.
35.3.4
A cooling water discharge pipeline having full capacity discharge is to be connected to the sea
chest.
35.3.5
The open area of the strainer plates is to be not less than four times the inlet pipe sectional
area.
Where it is impractical to meet the requirements of 6-1-2/35.3.2 and 6-1-2/35.3.3 above, two smaller
sea chests may be arranged for alternating the intake and discharge of the cooling water, provided
6-1-2/35.3.1, 6-1-2/35.3.4 and 6-1-2/35.3.5 above are complied with.
求解释: 上面所述主辅机功率是输出功率的总和还是单个主机或者辅机输出功率最大者?
还有 就是是不是冰区航行的船舶才有此要求? 有没有专用的海水箱容积计算公式或者经验公式? |
