Shen Neng 1 Grounding on the Great Barrier Reef

On Saturday 3rd April 2010 the coal carrier "Shen Neng 1" grounded at Douglas Shoal, in the middle of the Great Barrier Reef. The ship sustained damage during and after the grounding which resulted in some oil pollution.

Within 20 minutes of the grounding the RPS APASA RESPONSE duty officer had been activated and was running trajectory modelling in order to determine the fate and trajectory of the released oil.

The RPS APASA RESPONSE personnel assisted the client (the Australian Maritime Safety Authority) with the response for the Shen Neng 1 for over a month by providing 4 trajectory bulletins a day (for the first week), a comparison of possible Places of Refuge and 3D fates modelling.

Montara Well Blow-Out

On the 21st August 2009 the Montara well head platform in the Timor Sea suffered a blow-out resulting in oil, gas and condensate being released into the sea.

RPS APASA RESPONSE was tasked with trajectory modelling and oil spill forecasts were issued from day one. Ongoing spill forecast bulletins were required and issued to the client (AMSA and DEHWA) using OILMAP and various forecast datasets to develop a "consensus forecast" of what was expected to occur.

The bulletins typically included forecasts of the winds and currents and the forecast of the spill movement. These spill forecasts were checked daily against aerial observations and satellite imagery to ensure accuracy was maintained throughout the incident.

RPS APASA RESPONSE used a combination of daily overflight operations, spill trajectory modelling and the use of satellite images to ensure the most detailed understanding of the movement and fate of the spilt Montara oil throughout the entire 73-day incident.

Pacific Adventurer Oil Spill

On the 11th March 2009, the 185 metre container ship the Pacific Adventurer lost 31 containers in heavy seas about seven nautical miles east of Cape Moreton. The fallen containers caused damage to the ship and resulted in the loss of heavy fuel oil.

The RPS APASA RESPONSE duty officer was activated and asked to model not only the trajectory of the heavy fuel oil but also the fate and trajectory of the contents of the containers; ammonium nitrate.

An RPS APASA RESPONSE officer was also involved in the beach clean-up assessment.

"Maritime Safety Queensland-led clean-up operations formally concluded on 19 June 2009 after an independent consultant (Asia Pacific Applied Science Associates) declared that beaches were clean (according to national plan guidelines)."
