BSEE: Hazards associated with cranes on idle facilities

BSEE inspectors have observed multiple crane components in poor condition on idle facilities throughout the Gulf of Mexico. Additionally, BSEE inspectors have noted various crane components missing that were previously attached by crane cables.

After extended periods of inactivity, with little or no operator inspection and maintenance, lifting equipment deteriorates due to harsh offshore environmental conditions. BSEE inspectors have observed corrosion on numerous crane cables, which support main blocks, auxiliary balls, overhaul/headache hook balls, and anti-two block equipment. Without proper oversight, the weakened cables have parted, resulting in cables and associated crane components dropping from elevation.

In addition, diminished integrity of wire rope and synthetic slings exposed to weather elements have also been identified as dropped object hazards. These slings are sometimes used to support heavy water hoses and diesel fuel hoses. If the slings fail, there is a potential for severe consequences. The dropped objects can potentially pose a safety risk to personnel boarding the facility or individuals nearby the facility, such as offshore support vessel crewmembers or commercial/recreational fishermen. The dropped objects can also become marine debris, posing environmental risks.

Along with dropped object hazards, potential pollution threats associated with inactive cranes on idle facilities have been identified by BSEE inspectors. Defective fittings, hoses, and leaking diesel/hydraulic reservoirs have been observed across multiple idle platforms.

As most inactive cranes on idle structures have been taken permanently out of service, they no longer require an annual inspection by a qualified inspector. Consequently, in most cases preventative or corrective maintenance has been disregarded.
