Untitled Much bandwidth has been expended on social media, including MAC’s Maritime Investigation group on LinkedIn, following the collision between the German-flagged Hapag-Lloyd Colombo Express and the Singapore-flagged Maersk Tanjong at the northern end of the Suez Canal on 29 September. Captured on a mobile phone, the incident caused serious disruption to canal operations, dunked several containers overboard, and put a 20 metre dent in the port side of Colombo Express.

No-one was hurt there was no environmental impact and both vessels were able to continue on to an anchorage to await recovery of the lost containers and investigators from the Suez Canal Authority.

Even at this early stage there may be lessons to be learned.

A man apart: Fatigue and both physical and cultural differences played key roles in the grounding of the bulker Tundra.

Take one fatigued pilot, add cultural power distance, loss of situational awareness, a dash of unimplemented Bridge Resource Management , inadequate master-pilot exchange and passage planning and there’s a very good change of something unpleasant happening. TSB Canada’s investigation report into grounding of the bulker Tundra off Sainte Anne-de-Sorel, Quebec, is an interesting collection of what-not-to-does.

Groundings in which pilots are involved are among the most expensive. A study by the International Group of P&I Clubs estimated that although groundings only account for 3 per cent of incidents resulting insurance claims of more than $100,000 they accounted for 35 per cent of the cost of claims at a cost of $7.85m for each incident. That compares with collisions, which accounted for 24 per cent of incidents and costs, and fixed and floating object claims which accounted for 64 per cent of incidents but 33 per cent of claims.

There’s money in them thar ills.

When the pilot boarded the Tundra he did not have up-to-date information regarding the buoys he intended to use for navigation. One buoy has been removed, which was not necessarily going to be problem since the next buoy had distinctly different characteristics than the missing device and the pilot would have recognised the situation and adjusted accordingly. He did not have a documented passage plan – his was in his laptop. Continue reading »

Damage to Arklow Raider after grounding at entrance to River Boyne

Two recent reports over the past few months, one a grounding the other collision and both with vessels under pilot’s advice, serve as useful lessons regarding hydrodynamic effects and vessel safety even when an expert is aboard.

In the case of Arklow Raider, she grounded as she passed the bar at the mouth of the River Boyne, Eire.

The Marine Casualty Investigation Board report says: “As the vessel approached the river bar, its speed was reportedly reduced. The data from the port’s VTMS gave a speed over the ground of approximately 5.4
knots between the Green and Bull light marks. The speed was 5.1 knots as the vessel passed Aleria light. The speed then dropped to 4.9
knots. At 19:30 hrs. the course was 053°T at 4.3 knots.

“The predicted time of high water was 19:54 hrs., the grounding occurred 20 minutes before the predicted high water. At 19:34 hrs. the vessel would not respond to rudder commands. The Master used both engine and bow thruster in an attempt to resume the correct course. At 19:35 hrs. the vessel touched bottom, veered to port and ran aground”.

Bad parking led to bump

Bank effect caused the passenger vessel Juno the sailing boat Bolero, but Bolero was moored in the wrong place and difficult for the navigators to see until almost too late.

Says the Swedish Transport Agency report summary:

“On the 27th May 2010 at 09.00 am the passenger vessel Juno departed from Gothenburg with 27 passengers and 11 crew members on board. The destination was Stockholm via Göta kanal.
