摘要
船舶在海上抛锚时,可抛锚的极限水深主要取决于锚机的起锚能力、锚链及锚的质量等因素。基于此,用锚机功率、锚重以及单位长度的链重等因素来确定可抛锚的水深极限值。此外,由于锚机的可用功率会随着船龄的增加而有一定的损耗,因此用合理的经验值来估算锚机的实际可用功率,并计算锚机在实际可用功率下可抛锚水深的极限值。
When dropping an anchor, the limit of the allowed anchoring depth is limited by the ability of windlass heaving anchor, weight of anchor chain and anchor etc. The method of calculating the limit of anchoring depth is proposed according to the power of windlass, the weight of the anchor and the anchor chain and some other factors. Windlass power usually gradually degrades due to aging, therefore, the effective power of windlass is adjusted according to practical experience when calculating the limit of anchoring depth.
