Chemical burn injury during maintenance
A concentrated fuel biocide—intended solely as a fuel additive—was incorrectly used as a soaking and rinsing cleaning agent. The chemical mixture soaked through the worker’s standard cotton coveralls. Unaware of the chemical’s corrosive nature, the worker did not wash the skin immediately and wore the contaminated coveralls the following day, resulting in prolonged skin contact and severe burns requiring hospital treatment.

Unsafe attempt to transfer between vessels with no gangway
The unsafe act was immediately stopped and the individual was reminded of the company’s safe access requirements.
The attempted transfer was in clear view of both vessel bridges; however, no action was taken to stop the unsafe act or provide a safe means of access, indicating a lack of effective controls and a silent acceptance of unsafe behaviour. Although no injury occurred, the situation had the potential to result in a serious incident.

BSEE: poorly maintained crane components cause multiple injuries during personnel transfers
The Bureau of Safety and Environmental Enforcement investigated two incidents involving injuries to offshore personnel during basket transfers. In both incidents, a crane’s auxiliary line descended unexpectedly while personnel were being transferred. The incidents show the importance of timely maintenance, correcting known deficiencies, using stop-work authority, communicating clearly during transfers, and planning for medical evacuations before work begins.

High Voltage isolation near miss
The isolation and grounding were applied to the wrong system. Believing that the correct system had been isolated, the ROV team proceeded with the maintenance task on the junction box. After the maintenance was completed, it was discovered that the wrong system was isolated and grounded. The ROV being worked on had never been electrically isolated and had only ever been switched off using topsides computer control.
No injuries, electric shock or equipment damage occurred. However, the potential consequences were severe.

Diver injured foot during high pressure water jetting
he incident occurred during saturation diving operations on an Underwater Wellhead Completion (UWC) at a depth of 34m. The task involved using handheld high pressure (8000psi) water jetting equipment to remove marine growth in preparation for inspection and pressure testing. The diver momentarily lost body position when the hogging line slipped off the UWC. As this happened, the HPWJ lance/nozzle passed across the diver’s left foot, causing a high-pressure injection injury and an approximately 4 cm laceration to the left big toe.
