Recent inspections conducted by Australia’s National Offshore Petroleum Safety Authority, NOPSA, and information provided to NOPSA have raised concerns regarding the general condition of some Totally Enclosed Motor Propelled Survival Craft (TEMPSC) currently in use in the offshore regime.


Inspection findings have resulted in nine enforcement actions on facility operators in the past four months.

The enforcement actions focused primarily on the lack of effective routine maintenance and inspections being conducted on facility TEMPSC.

TEMPSC were identified with damaged or broken safety harnesses, unsecured and loose items, and illegible safety and operating instructions. A shortfall in the competencies of personnel assigned to essential lifeboat duties was also noted. Continue reading »

Will the PLC do what's expected or what it's told?

Australia’s National Offshore Petroleum Safety Authority has issued a warning regarding the potential for malware or inadequate design of safety-related control functions to cause death or injury when they do not perform in the intended manner. While the alert is aimed at the offshore industry it applies equally to the maritime industry where there has been a number of accidents involving programmable logic controllers.
What happened?
NOPSA has encountered a number of instances, in a diverse range of applications, where Operators have introduced equipment or systems that have potential weaknesses in the design of their safety-related control systems.
In some cases, Operators have been unaware of the significance of control systems as control measures against Major Accident Events and Dangerous Occurrences, and have consequently not used appropriate safety management techniques in their design and operation. Continue reading »

image Discrepancies between procedures and shipboard practice may have contributed to the death of an integrated rating aboard the floating storage and offloading tanker Karratha Spirit while untying from a buoy off Dampier, Western Australia says Australia’s Transport Safety Bureau, AMSA. Concern is also raised that vagueness regarding precisely when such a vessel can be termed ‘navigable’ means that there are times when a vessel falls outside the jurisdictions of Australia’s National Offshore Petroleum Safety Authority and AMSA.

Manriding Incident – Carabiner Failure

Potential serious injury was avoided because an offshore worker had hold of a cement hose when his carabiner failed. The carabiner was not properly checked before use and was not included in the maintenance regime, says Australia’s National Offshore Petroleum Safety Authority, NOPSA. Dirt in the carabiner seems to have cause the failure.

Says NOPSA: “On a semi-submersible drilling rig, the drill crew had completed rigging up for a cement job. After pressure testing the cement line, a crew member was required to open the low-torque valve. The valve was located at a height of seven metres above the rig floor and could only be accessed by using a tugger and man-riding harness.

With the assistance of a roustabout, the person in the man-riding harness connected to the wire rope from the man-riding tugger using a carabiner. Another crew member then operated the tugger to raise the man-rider up to the height of the low-torque valve.
