A fail safe interlock device should have prevented the drop

Incorrect electrical installation of a ‘fail-safe’ interlock and early activation of a wave compensator led to a fast rescue craft being dropped 18 metres while being deployed in an emergency, says Australia’s Transport Safety Bureau. The chief engineer, who was being medically evacuated, second mate and fourth engineer were injured in the incident on board the Isle of Man registered liquefied natural gas tanker British Sapphire.

ATSB says that that, in the process of lowering the rescue boat, the wave compensator mechanism on the fast rescue boat’s davit was activated early, before the rescue boat had reached the water. A fail safe interlock device should have prevented this by placing the wave compensator into standby mode, only becoming operational when the fast rescue boat was waterborne. However, the electrical installation of the interlock was incorrect and meant it could not work as designed, allowing the wave compensation unit to always operate and the fast rescue boat to make the uncontrolled descent to the sea.

The investigation identified safety issues relating to the commissioning, maintenance, testing, operating instructions and procedures for the fast rescue boat’s wave compensator and its safety interlock system. Further safety issues were identified relating to the job hazard analysis for the use of the fast rescue boat, crew resource management principles and approved training courses for fast rescue boats.

Tests were carried out on board the three sister ships, British Sapphire, British Emerald and British Ruby. with the wave compensator not working correctly on any of them. However, a crucial discovery was made when the engineers on board one of the ships noticed that the electrical drawings had been altered in red pen. As a result of this finding, BP Shipping asked Davit International to supply a set of ‘original’ electrical drawings. These drawings were then forwarded to the ships for further checking.

At 1145 on September 13, the crew of the BP-operated tanker, British Cormorant was carrying out a drill with the rescue boat when one of the lines snapped injuring three crewmen on the ship and causing the rescue boat to capsize which deposited the six crewmen into the water.

The Coastguard rescue helicopter from Lee on Solent was scrambled and recovered six crewmen from the water and landed them at Bembridge on the Isle of Wight.  The helicopter then recovered a crewman to Queen Alexandra Hospital, Portsmouth with suspected spinal injuries from the ship.

British Sapphire

Australia’s ATSB is investigating injuries to crew members of the BP-owned, Isle of Man registered liquefied natural gas tanker British Sapphire off Darwin, Northern Territory, on 16 May 2010. It is understood that two crew members were injured when the ship’s rescue boat fell after its winches failed during recovery operation. The boat had been launched as part of the evacuation of another crewmember who was suffering a suspected angina attack.
