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.

Foundering of the General Cargo Ship Tycoon – Investigation Report

On the morning of 8 January 2012, one of the permanent mooring lines holding the general cargo ship Tycoon in position in the inner moorings at Flying Fish Cove, Christmas Island, came free from its anchor. As a result, the ship moved forward and closer to the nearby terminal rock face, eventually making contact with the rock face as the weather and sea conditions deteriorated. Despite attempts to move it away, Tycoon continued to pound against the rock face. Eventually, the ship’s engine room began to flood through a tear in the hull. Shortly afterwards, the crew safely abandoned the ship. At about 1100 on 9 January, Tycoon suffered a catastrophic failure of its hull and the contents of the ship’s number two cargo hold, about 260 tonnes of bagged phosphate, were exposed to the sea.

Collision Between General Cargo Ship and Chemical Tanker in Dover Strait TSS – Investigation Report

On 9 October 2001, the 1009 gt general cargo ship Ash was en route from Odense, Denmark, to the Spanish port of Pasajes, with a cargo of steel coils. She had six crew on board and was making a speed of about 6.25 knots over the ground in the south-west traffic lane of the Dover Strait TSS to the south-east of Hastings. The 4,671 gt chemical tanker Dutch Aquamarine was also on passage in the same traffic lane, en route from Antwerp to Swansea. She had a mixed chemical cargo and a crew of 12 on board. She was making about 12.5 knots over the ground. Despite the fact that the weather was fine and the visibility good the watchkeeper on Dutch Aquamarine did not notice Ash in the period immediately before the collision until she was very close and right ahead. Ash was holed in the collision, she listed quickly to starboard, capsized and sank. The six persons on board jumped into the water and five of them were rescued by Dutch Aquamarine’s fast rescue craft.

Riser Disconnect and Blowout – Incident Investigation

This accident investigation report refers to the accidental riser disconnect and subsequent uncontrolled flow during drilling operations which occurred on Mississippi Canyon Block 538 in February 2000. The Ocean Concord (semi-submersible mobile offshore drilling unit) was in the process of running a liner on drill pipe when the lower marine riser package (LMRP) was inadvertently disconnected from the blowout preventer (BOP) stack. The disconnect resulted in the discharge to the sea of approximately 806 barrels of synthetic mud from the riser and 150 barrels of synthetic mud and 150-200 barrels of crude oil from the wellbore.
