Summary
A vessel crane wire failed while overboarding a concrete mattress for a pipeline crossing, dropping the load before it entered the water. The flash examines unresolved magnetic rope testing results, misunderstood operational limits and absent change management, and calls for better shore–vessel communication and lift routing away from existing pipelines.

Summary
A concrete mattress was being deployed as part of the construction of a pipeline crossing. As the load was swung outboard and before it entered the water, the crane wire parted causing the load to fall to the seabed.
