Microbial attack is a concern on some ships says Lloyd’s Register

Lloyd’s Register (LR) has said that certain ship’s tanks could be subjected to severe microbial attack, causing significant losses in plating thickness. According to LR, this is a result of biological action where the fluid in the tank has been stagnant during an enforced period of reduced operational status. Tanks likely to be affected are those that may have higher biological loads, such as Grey Water and Treated Black Water. Also vulnerable are Distillate (MGO) Tanks, which, if not used, could exhibit this phenomenon due to the presence of condensation.

The UK’s shipbuilding industry will be revitalised through a refreshed national strategy, the UK government has announced.

First published in 2017, the National Shipbuilding Strategy outlined ambitions to transform naval procurement, securing export and design contracts for British naval ships. Building on that success, the new release outlines the government’s further ambitions to reinvigorate the whole British shipbuilding industry while contributing to its levelling up mission to boost productivity, pay, jobs and living standards across the country.

Over £4bn of government investment aims to galvanise and support shipyards and suppliers across the UK, with new measures including Continue reading “UK government launches new national shipbuilding strategy”

Leading Maritime Cities report 2022 by DNV and Menon published

The 2022 edition of the Leading Maritime Cities (LMC) report was launched at an event hosted by the Singapore Maritime Foundation (SMF).

There have been many dramatic developments since the last edition of the LMC report was published in 2019. For one, we are still living with the pandemic. Two years of fluctuating restrictions have caused severe trade and travel upsets. Extreme weather events have made us all more acutely aware of the climate crisis, another major driver of change. Shipowners, charterers, cargo owners and lenders are gearing up for a decarbonized future, with rapid adoption of zero-carbon fuels expected over the next decade. Ongoing digitalization, including Continue reading “Leading Maritime Cities report 2022 by DNV and Menon published”

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.

The exterior houses a set of components, viewed via a bright LED display with polarised filter, in either metric or imperial measurement to suit the user’s preference. These features include an echo strength indicator to aid measurement, measurement self-verification to ensure Continue reading “Cygnus 1 ultrasonic thickness gauge certified to Class 1”

Practical aspects of the carriage of containers on dry bulk vessels

Practical aspects of the carriage of containers on dry bulk vessels

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”

Preventing wet cargo damage

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.
