On the morning of Sunday, 5 May 2002, construction operations were underway to install a new flare boom and to remove the old, 18,000-lb flare boom from Devon's MP-255 "A" platform (see Attachment 2). The old flare boom was to be removed from the platform's north side and lowered onto a work boat by using a temporarily installed rental crane. The old flare boom was cut loose from the platform and held by the rental crane. While the load was being swung around the northeast corner of the platform, prior to lowering it onto the boat, the welded base of one of the rental crane's two support braces failed. This caused the crane suddenly to be uprooted from the platform and be pulled overboard into the Gulf of Mexico.
