Use of Rudder Trunk for Smuggling

On more than one occasion, vessels have been arrested in port, after discovering cocaine (as much as 100–300 kg) and stowaways in the rudder trunk of these vessels. The void space has been accessed from sea level, by climbing up into the trunk from underneath.

Cracks in Main Deck in Way of Hatch Corners

During survey several fatigue cracks were found in way of the elliptic curved corner of the opening in way of cargo hatch ways on the main deck. A shedder plate had been welded to the main deck in way of the hatch opening corner. This is believed to be the most probable cause of the crack in the deck plate.

Corrosion Under Walkways on Oil Tankers

During the main hull survey of an oil tanker, it was noted that deep spots of grooving corrosion had taken place under the walk ways, which is an almost inaccessible area, when the walkways are in place. The original plate thickness was 15 mm, but several grooved and corroded areas were found with only 5 mm of plate thickness; extending in the transverse direction of the deck.

Incident Information on Lifeboat Drill Near Casualty

During a lifeboat drill at sea in good weather conditions, the starboard lifeboat was lowered to the embarkation deck. In this operation the top link of the forward chain for the connection between the davit floating block and the hook on the lifeboat parted, such that the entire load from the lifeboat was transferred to the aft hook/chain. As the aft chain could not withstand the excessive weight, the lifeboat accidentally dropped to the sea.
