Typical Anchor Weights

Note: the anchor weights depicted above for the 210,000 and 260,000 m3 LNG vessels are one size greater than the Rule requirement but have been included as they represent ‘as-fitted’ anchors on a large number of vessels of this size.

Seabed Factors

The purpose of this tool is to estimate the holding power of an anchor on a particular seabed; ie - where the seabed (ground type) is known. It is not for use specifically as a design tool.
