Tritex NDT launches a thickness gauge for mounting onto drones

Posted on February 27, 2018February 27, 2018 by News Hound

Tritex NDT has launched a new ultrasonic metal thickness gauge specifically designed for mounting onto drones for high level inspections.

The gauge uses multiple echo to completely ignore coatings up to 20mm thick and the single crystal probe ensures accurate readings on curved surfaces, such as storage tanks and pipelines. Remaining metal thickness and corrosion levels can be quickly and more easily checked without the need for scaffolding or rope access.

The Multigauge 6000 Drone Thickness Gauge OEM transmits real time measurements wirelessly up to a distance of 500 metres using its integrated RF transmitter. The readings are displayed and stored on dedicated Communicator software within templates in a grid or string format.

The gauge weighs just 45 grams and the plastic probe weighs only 15 grams. Jon Sharland, Sales Manager at Tritex NDT Ltd, said Continue reading “Tritex NDT launches a thickness gauge for mounting onto drones”

Libya releases tanker carrying fuel to rival government

In order to improve ship standards, the International Group of P&I Clubs has said it will continue to conduct survey triggers for seagoing vessels of 10 years of age or more carrying heavy fuel oil cargoes.

As a result, all sea-going vessels that are 10 years old or more and have carried heavy fuel oil as cargo within the previous 12 months will be subject to condition survey, unless:

– The vessel has undergone a P&I club condition survey during the previous 12 months.
– The vessel has undergone a Special Survey during the previous 6 months.
– The vessel has a valid Condition Assessment Program (CAP) rating of 1 or 2 with a classification society having membership in the International Association of Classification Societies (IACS).

Operators should have in mind that a declaration is now required so that Continue reading “Ships carrying heavy fuel oil cargoes subject to ongoing condition surveys”

Liberia Maritime Authority issues an advisory notice for the safe transport of bauxite

Posted on February 22, 2018November 13, 2024 by News Hound

The Liberia Maritime Authority has released a Marine Advisory notice to provide guidance for the safe transport of bauxite. It also gives the potential risks regarding the carriage of certain Group A bauxite in bulk due to its potential to undergo dynamic separation.

After the investigation into the loss of the M.V. BULK JUPITER in 2015 with a cargo of bauxite, IMO published CCC.1/Circ.2 on Carriage of Bauxite that may liquefy. At the time, bauxite was listed in the IMSBC Code as a Group C cargo (cargoes neither liable to liquefy- Group A or possess chemical hazards Group B).

For a more peer reviewed report on the nature of bauxite cargoes and to develop a globally applicable transportable moisture limit (TML) test for bauxite cargoes, the Global Bauxite Working Group (GBWG) was established in 2016.

GBWG indicated that Bauxite Fines containing more than Continue reading “Liberia Maritime Authority issues an advisory notice for the safe transport of bauxite”

UK P&I Club releases a detailed guidance report on packing dangerous goods for carriage by sea

Posted on February 22, 2018April 9, 2025 by News Hound

As accidents involving dangerous goods continue to occur with regularity at sea, the UK P&I Club has published a comprehensive guide running to more than 100 pages to support operators who pack dangerous goods into cargo units for onward transportation by sea.

As part of the new guide, UK P&I Club makes the following points and advice:
– Improper packing practices and loads not properly secured increase the number of accidents across the supply chain and have as a result caused damages, loss and injuries, both on land and at sea.
– There is a lack of guidance regarding personnel working in the cargo handling industry. That is where the Code of Practice for Packing of Cargo Transport Units (CTU) becomes relevant. The CTU provides information regarding packing cargo in containers, in order to comply with the requirements of sea and land transport.
– Classification of dangerous goods: The first key task for an operator is to make sure that the dangerous goods on board have the correct UN classification.
– Selection of Continue reading “UK P&I Club releases a detailed guidance report on packing dangerous goods for carriage by sea”

Guidelines for ensuring the safe carriage of cocoa butter

Posted on February 22, 2018May 12, 2025 by News Hound

Members of the CINS Organisation (the Cargo Incident Notification System) have issued guidance and guidelines for the carriage of cocoa butter in freight containers, under the principles set out in the IMO/ILO/UNECE Code of Practice for Packing of Cargo Transport Units (CTU Code).

Nature of cocoa nutter cargo

Cocoa butter is derived from whole cocoa beans which are fermented, roasted, and then separated. About 54–58% of the residue is cocoa butter, containing 57-64% of saturated fats and 43-36% unsaturated fats. Cocoa butter becomes soft and malleable at 30-32°C and can melt at 37°C. Having become warm or molten, it can retain the latent heat and remain in such a condition down to as low as 17°C.

Upon heating, cocoa butter expands and may cause it to Continue reading “Guidelines for ensuring the safe carriage of cocoa butter”

New class notations aim to improve stern tube bearing performance

Posted on February 16, 2018April 9, 2025 by News Hound

DNV GL has revised its class rules for single stern tube bearing installations and introduced two new class notations, “Shaft align(1)” and “Shaft align(2)”, to help customers better manage the risk of stern tube bearing failure. The new class notations can be assigned to both newbuilds and vessels in service in conjunction with propeller shaft withdrawal.

The classification rules covering shaft alignment are formulated to achieve an acceptable distribution of loading on the shaft bearings and lubrication of the aft bearing, taking into consideration the bending moment induced by the propeller during operation. However, during turning manoeuvers at higher ship speeds, exaggerated propeller bending moments can occur, potentially resulting in a reduced shaft- Continue reading “New class notations aim to improve stern tube bearing performance”

Operators and surveyors urged to test cargo hold’s bilge system to minimise claims

Operators and surveyors urged to test cargo hold bilge systems to minimise claims

The UK P&I Club has reminded those working in the marine industry that significant insurance damage claims can result if a bulk cargo is damaged due to the leakage of the bilge system into a loaded bulk cargo hold.

To reduce the chance of such cargo damage, operators and surveyors are advised to inspect and test the cargo hold bilge system as part of the routine pre-loading checks of the cargo holds.

Inspection and testing of cargo hold bilge system non-return valves should be included in routine pre-loading checks of the holds. These non-return valves may not be seated tightly, because of the Continue reading “Operators and surveyors urged to test cargo hold’s bilge system to minimise claims”

ILO adopts a new Code of Practice to improve safety and health in shipbuilding and ship repair

Posted on February 12, 2018February 12, 2018 by News Hound

Representatives of governments and the social partners from around the world gathered at the ILO from 22 to 26 January 2018 to adopt a revised code of practice on safety and health in shipbuilding and ship repair.

The new code reflects the many changes in the industry, including the use of robotic systems, over the last 43 years since an earlier code was adopted by the ILO. It focuses on the need for a preventive approach based on occupational safety and health (OSH) management systems, management of change and safe work plans among others.

Participants emphasized the importance of improving occupational safety and health (OSH) in shipbuilding and ship repair. Improved OSH performance will reduce Continue reading “ILO adopts a new Code of Practice to improve safety and health in shipbuilding and ship repair”

Autonomous vessels – the challenges and opportunities in design

Posted on February 9, 2018April 9, 2025 by News Hound

Automation presents a set of unique challenges to designers, insurers and operators of ships. In this article, reprinted from the Shipowners P&I Club website Keir Gravil, a naval architect at Frazer-Nash Consultancy in Bristol, UK discusses some of the key issues that could face automated ships of the future from a design perspective.

It is a truth recognised by many industries that the future of transportation lies with greater automation. Over the last 50 years we have seen huge changes not only in shipping, but in every form of transportation and vehicle. Aircraft now incorporate automation routinely on flights around the world, cars are being developed to drive themselves and many railways have been totally automated for some time. As each step in the evolution of transportation progresses, the human element of control is reduced or eliminated altogether. But what of shipping? Surely an industry the size and scope of international shipping faces unique challenges in the realm of automation?

The background

It is often the job of ship designers, especially those in the naval defence industry, to think ahead and anticipate future technological changes. One could argue that Continue reading “Autonomous vessels – the challenges and opportunities in design”
