The Cygnus 1 ultrasonic thickness gauge is certified to Class 1, Div 1 (“Zone 0”) for ATEX, IECEx and CSA-US. The Cygnus 1 is specifically designed for measuring metal thickness to determine wastage or corrosion in Zone 0, Zone 1 hazardous and potentially explosive environments. It has a highly durable, shock-proof and splash-proof (IP65 rated) construction – this heavy-duty unit is supplied ready to use, and offers up to 12 hours continuous testing before recharge is necessary, with no plant shutdown or hot work permit required.
Mark Dunbar, Surveys Manager at West P&I Club, has highlighted practical aspects on the carriage of containers onboard dry bulk vessels. And as he says, individual cases will vary widely so the following should not be taken as exhaustive, but as an aide memoire for the major factors that need to be considered and addressed.
– Bridge visibility needs to meet SOLAS requirements.
– Vessel stability including bending moments and shear forces to be verified as within limits.
– Container stacking weights – check CSC plate for maximum allowable – US 53 foot containers are usually significantlylower than standard ISO containers.
– Strength of tanktop/hatch covers/deck plating – remember all the weight of a container is distributed Continue reading “Practical aspects of the carriage of containers on dry bulk vessels”
Claims relating to wet cargo damage are all too frequent. Many of these can be avoided entirely with a robust pre-loading condition checking procedure. While humidity and condensation are inevitable challenges through the supply chain, pre-existing CTU damages should be an easy check.
As TT Club regularly articulates, around 65% of cargo damage incidents are attributable in part to the way that goods are packed within the cargo transport unit (CTU). The CTU Code and the more recent ‘CTU Code – a quick guide’ and complementary container packing checklist published by the Cargo Integrity Group, provide invaluable guidance for actors in the supply chain to mitigate such risks.
