Summary
A mezzanine deck shifted during installation on a floating offshore facility, damaging pressurised gas piping and a valve. The crew subsequently cut a brace without a change request or work permits before the installation manager stopped work. The alert examines shortcomings in lift planning, hazard communication and supervision, and recommends reinforcing effective stop-work arrangements.
