Anchor and Chain Cable Survey
Anchors and chain cables are ranged/examined at Special Survey; gauging is required from Special Survey No.2 onward or where class Rules/surveyor require, not link-by-link every cycle.
Operational Explanation
Anchors and chain cables are ranged/examined at Special Survey; gauging is required from Special Survey No.2 onward or where class Rules/surveyor require, not link-by-link every cycle.
Regulatory Reference
Applicable class survey Rules; IACS UR A1.6 12% mean-diameter wastage criterion; W18 for manufacture/testing.
Scope of Application
Measurement extent/locations follow survey number, Rules and surveyor. Renew affected length where mean diameter at most worn part is reduced by 12% or more.
Procedure / How to Complete It
- Range and clean cable as required.
- Examine anchors, joining shackles and links.
- Gauge from SS No.2 or where required.
- Use class-Rule extent/locations.
- Apply A1.6 and surveyor decision to renewal.
Practical Example
At first Special Survey cable may be ranged/examined without a universal full link-by-link campaign; findings may extend gauging.
What Typically Goes Wrong
Declaring full five-year gauging and measuring every link at every Renewal/Special Survey.
