ClassNK has investigated behaviour of waves acting on windows located considerably above the freeboard deck of ships where the navigation bridges are located forward of the midship, such as onboard Ro-Ro cargo ships. Based on the investigation results, ClassNK has issued amendment of rules for ship windows.

It has been found out that there is possibility waves can hit the windows located considerably above the freeboard deck due to waves rolling over the foredeck and running up along the front walls, even though the wave height may not be so high that the wave directly reaches the windows. In fact, cases have been confirmed in which navigation bridge windows seem to have been damaged by the aforementioned phenomenon.

The single most predominant factor associated with the failure of cargo lashings is the incorrect application of bulldog grips. Tony Watson, Risk Assessor at UK P&I Club has issued some advice on the correct application of bulldog grips in order to minimise damage to cargo.

Bulldog grips are commonly used for the securing of project cargo, both under and below deck. They are also used on ships on mast stays and crane wires, although swaged connections are now more common. Failed lashings can result in significant damage to cargoes and can also pose significant risk to the wellbeing of crew members and the safety of the ship.

Isle of Man Ship Registry has issued a Manx Shipping Notice (MSN) to provide guidance to all Isle of Man Registered vessels on the installation and maintenance of oxy-acetylene and refrigeration gas equipment. This MSN replaces Industry Circulars 14 and 20 which are withdrawn.

Gas cylinders containing refrigeration gas and nitrogen are normally sent to the ship full and returned to a service provider when empty. These gases are not corrosive and providing the bottle contains the original gas sent from the supplier (and gas has not been added to the bottle on board) the bottles can be periodically inspected and tested at intervals in accordance with the RID/ADR regulations. In most cases, for refrigeration gases and nitrogen this is at 10 yearly intervals.
