Drilling Platform Belongs to Diamond Offshore and National Safety Agency Issues Operations Prohibition Notice on the Rig.
An offshore oil worker sustained serious injuries on the Ocean Monarch drilling platform owned by Diamond Offshore while operating in the Bass Strait in Australia, leading the national offshore safety agency (NOPSEMA) to issue a “prohibition notice”.
Read here also the news about the Petrobras operator who suffered a serious accident aboard the P74.
NOPSEMA stated that the worker was injured on September 17, after a drill line fell onto the drilling floor of the “Ocean Monarch” when the tension applied during the drilling line replacement work exceeded the breaking strength of the steel cable, causing it to fail.

According to the safety agency, the impact resulted in significant injuries, and the equipment that fell from a considerable height had the potential for fatal injuries.
In understanding why the incident occurred, the NOPSEMA stated: “While changing the drill line, the operator could not monitor the amount of tension applied during the pulling operations; as a result, excessive tension was applied to the drill line, exceeding its breaking point, causing the steel cable to fail, resulting in the drill line falling onto the drilling floor and significantly injuring a member of the workforce.”
After an inspection of the site, NOPSEMA determined that operations should not resume until Diamond Offshore implements appropriate systems and work practices to remove the threat to the health and safety of the vessel’s crew.
“NOPSEMA continues to investigate this matter, and other enforcement actions, if necessary, may be taken,” the regulatory agency said on Friday.
According to available information, at the time of the incident, the rig was working for Cooper Energy on the Annie-1 well. The incident occurred one day after Cooper announced it would cease its drilling program off the coast of Australia due to the failure of two mooring chains on the “Ocean Monarch.”
