What happened - icon

What happened?

A 30in (76cm) conductor pipe was being hoisted by a starboard crane.

What happened - icon

Why did it happen?

Protection collar was not torqued tight enough on the pipe end.

Collars were only visually inspected to make sure they were covering the pipe ends.

No mandatory checks for physical tightening.

Factors that can affect protectors during loading/unloading/transport:

  • Protectors may not be torqued tight enough.
  • Protectors are made of rubber and when knocked, they slacken easily.
  • Protectors could slacken in transit due to vibrations or knocked by other objects, hit by water etc).

What did they learn?

Ensure protection collars are secured before starting to load the pipes.

Gantry team should visually inspect pipe protectors that are accessible and visible/practical to check.

  • Any slackness observed should be reported to the relevant authority.

Incident details should be passed to the vendors, requesting for extra vigilance on securing protectors on pipes.

Ask yourself or your crew

Has anything like this ever happened on your site/vessel?

How do we check that all protection collars are in place and protect the pipes effectively before starting the job?

  • If you observe anything abnormal, who do you report it to?

What other checks do we perform before lifting pipes/other loads?

What other risks are there with lifting and hoisting activities on vessels?
