Action number: AO-2018-022-SAN-001

Collision between the tug Arafura Sea Delta and general cargo ship Thorco Crystal, Weipa Harbour, Qld. on 24 June 2017
Safety message from ATSB
Masters of ships and tugs, pilots and others involved in handling vessels in confined waters or in proximity to other vessels are reminded of the hazards posed by hydrodynamic interaction (interaction). An awareness of the pressure zones around a moving vessel and an appreciation of the effect of speed on interaction forces can help vessel handlers foresee a potential interaction situation developing and allow them to deal with it. The effects of interaction can be amplified by an increase in vessel speed, the presence of another vessel or if the flow of water around the vessel is influenced by tidal streams or by entering a narrow or shallow channel.
Groundings made by bulk carrier Ocean Prefect at Ahmed Bin Rashid Port, Umm Al Qaywayn, United Arab Emirates
On 10 June 2017, the UK registered bulk carrier Ocean Prefect grounded when approaching Ahmed Bin Rashid Port, in Umm Al Qaywayn, United Arab Emirates. The vessel was not damaged and was re-floated 12 hours later. During a second attempted entry into the port the following day, Ocean Prefect again grounded but, despite the breaching of three ballast tanks, the vessel continued to its berth. Two harbour pilots were on board during the groundings. There were no injuries or pollution.
Safety lessons (from MAIB)
Accident during pilot transfer between general cargo vessel Sunmi and pilot transfer vessel Patrol with loss of 1 life - Location: River Thames, London, England.
At 1812 on 5 October 2016, a Port of London Authority sea pilot was in the process of boarding the Bahamas registered general cargo vessel Sunmi from the pilot launch Patrol when he fell and was crushed between the two vessels. He died at the scene despite prompt medical attention from Royal National Lifeboat Institution and local ambulance crew.
Grounding of the ultra-large container vessel CMA CGM Vasco de Gama, Location: Thorn Channel, Southampton, England.
In the early hours of the morning on 22 August 2016, the 399m long ultra-large container vessel CMA CGM Vasco de Gama grounded on the western side of the Thorn Channel whilst approaching the Port of Southampton. The vessel was the largest UK-flagged vessel at the time and had two of the port’s specialist container ship pilots onboard.
The ship ran aground on a rising tide and on a flat shingle/sand sea-bed. A combination of tugs and ship’s engines enabled it to be re-floated soon after grounding.
MAIB has embarked on a study into the human factors associated with the use of modern electronic navigation aids and the implementation of mandated navigation standards.
Collision between pure car carrier City of Rotterdam and ro-ro freight ferry Primula Seaways, Location: River Humber, England.
