The Liberia Maritime Authority has released a Marine Advisory notice to provide guidance for the safe transportation 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.
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.
The International Centre of Island Technology (ICIT) and the European Marine Energy Centre (EMEC) have joined forces in a year-long project to tackle biofouling in the marine renewable energy sector.
Under the auspices of the Biofouling in Renewable Energy Environments – Marine (BioFREE) project researchers will look at practical strategies to minimise the impacts of biofouling which can decrease the efficiency of energy generation and lead to corrosion of renewable technologies.
You are invited to join the International Institute of Marine Surveying, Marine Surveying Academy and International Marine Contractors Association in person, or as an online delegate, for a special one-day eCMID AVI seminar. During the day, delegates will be given an update on the eCMID accreditation programme, the use of the new eDatabase, concluding with some essential presentations in the afternoon session.
Following the successful seminars held last year in Amsterdam and Singapore, the team has chosen London this year. The seminar will take place on Tuesday 22nd May at the Park Inn by Radisson, Bath Road, Sipson, Heathrow UB7 0DU adjacent to London Heathrow Airport for ease of transportation.
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”
