High
Potential Near Miss on THE West Aquarius drilling rig. ExxonMobil AND CHEVRON CANADA ARE the PRINCIPAL
current oil rig operatorS.
December 3, 2014
Hibernia Management and Development Company (HMDC) reported a
high potential near miss on West Aquarius drilling rig that occurred on
December 3, 2014. A bracket for the
derrick elevator service loop dropped 22.5 meters (67 feet). The service loop bracket is installed in the derrick/mast. The service loops are
power cables and/or hydraulic hoses for providing either power or fluids
service. The bracket holds the wires/hoses together, that is also called wire
holder. The bracket weighs
approximately 5 kg (11 pounds).
Personnel were working on the drill floor, but not in the area
of the dropped object. Nobody was
injured.
There are ways of minimizing the fall of a bracket. In an oil
derrick separate service loops which are power cables and/or hydraulic hoses are
affixed at one end to a top drive and affixed at an opposite end to an oil
derrick end, adding a series of polyurethane supports or rungs along the length
of the separate service loops to provide a little lateral motion but to limit
the overall amount of lateral motion. The
rungs will also help insure that the cables and hoses do not wrap themselves
around everything when the wind blows. In
order to carry the weight of the cables, two parallel steel cables are affixed
on either side of the copper cables, and two steel cables are affixed on either
side of the hydraulic hoses. These steel cables will be terminated at the
derrick and the top drive by being affixed to steel brackets received in steel
mounting plates all designed to withstand the loads.
