Roughneck Crushed from Falling Container – Incident Investigation

During a lifting operation in connection with offloading of a vessel, a roughneck was crushed between a container hanging in a crane hook and a row of containers on the cargo deck. At the time, he was in a position which made it impossible to escape the cargo.

Maersk Drilling Ultra Deepwater Semi-Submersible Rig

A Brief History of US Offshore Oil Drilling

The BP Deepwater Horizon explosion in April 2010 occurred after a dramatic, three-decade-long reconfiguration of how the United States and several other nations drill for oil. Technology, law, and geology pushed oil exploration farther from U.S. shores, as land-based exploration became less fruitful, and the global demand for energy ramped up. Oil production off American coasts began well over a century ago, but the move into deepwater and ultra-deepwater is a relatively recent phenomenon. This post presents a brief history of offshore oil drilling based on a relevant staff working paper by the National Commission on the BP Deepwater Horizon oil spill.

Fatal Fall Through “V” Door Onboard Offshore Platform – Investigation Report

This accident investigation report refers to the occupational accident that occurred onboard the platform workover rig Pride 14 on 17 June 2002. The rig was being erected preparatory to conducting workover operations. While the derrick was being raised, a gate across the V-door inadvertently opened. The driller, who was apparently braced against that gate, fell backwards, lost his hard hat, and was fatally injured when he impacted equipment on the lower level, 19 feet below the rig floor.

PSA Report on Status and Trends for Work Accidents for 2012

Last April PSA Norway released its annual report on trends in risk level on the Norwegian shelf (project started in the year 2000). The objective of this annual report is to measure the impact of the industry’s HSE work, to identify any areas that are critical to HSE and to increase insight into potential causes of accidents. In this post we present the results of the report regarding work accidents involving fatalities and serious personnel injuries.

The Probability of an Offshore Accident

Risk is the product of frequency and consequence. Accordingly, high consequence events which occur infrequently may contribute as much risk as frequent events which have smaller consequences. Estimating the frequency with which events occur is as important to overall risk as accurately predicting the consequences. One way of estimating frequency is to look at historical records. The information presented below are an abstract from the “Safety of offshore oil & gas Impact Assessment Annex I” working paper from the European Commission, published in 2011 to accompany the proposal for a regulation of the European Parliament on safety of offshore oil and gas prospection, exploration and production activities.

Fire on Offshore Platform Caused by HVAC Unit – Investigation Report

This investigation report refers to the fire that broke out on Songa Dee on 4 December 2007. At 13.52 hours on 4 December 2007, the fire alarm sounded on the Songa Dee. The living quarters and important rooms such as the radio room, control room and emergency preparedness center were efficiently evacuated during the course of a few minutes. The fire was located in HVAC Unit No.2 and large parts of the living quarters were filled with thick smoke from the cooling and filter unit in the HVAC system. No one was injured during the incident, but the rapid, intense spread of smoke means that the incident is classified as a potential major accident.

Hydrocarbon Leak from Well Flexible Riser – Investigation Report

This investigation report refers to a hydrocarbon leak which occurred from a well flexible riser during a planned shutdown on Visund on 9 April 2011. Oil film and gas bubbles were observed in the sea near the production risers on the east side of the facility.
