Takeaways
Key points from this episode
- An in-water survey can satisfy some class intermediate or renewal requirements during a cargo port call, subject to the society's acceptance.
- Propulsion, thrusters and sea suctions are isolated and locked out before any diver enters the water.
- Shaft withdrawal, major steel renewal and full coating renewal remain dock work.
- Survey documentation and any non-destructive testing results are what the class society and technical manager use to decide whether a drydocking is actually required.
