INT_IMCA_Dropped GRP cover during subsea lifting_09.2026.pdf

What happened?

A vessel was lifting and relocating a Pipe Line End Manifold (PLEM) GRP Top Cover when the load became detached and dropped approx. 7m, landing on the side of the PLEM bottom GRP structure. The fibreglass lifting points failed on the GRP cover, but there was no damage to the PLEM or bottom GRP structure, nor any injuries to personnel. The Top Cover has two different types of lifting points. One set is designed for deployment and consists of pairs of profiled, reinforced holes where round slings are routed. The other set is designed for subsea relocation and consists of bars designed for easy connection to ROV hooks.
