06/07/05 Leading companies join Lashing@Sea project to pursue safety and efficiency
The Joint Industry Project Lashing@Sea has been launched to address the need for the right balance between safety and operational efficiency for container, Ro-Ro and heavy lift transport. Renowned companies recently have joined the project.

The new and innovative study in the Netherlands will look at the problem of hundreds of containers that are lost overboard every year. It is of concern that the cause of some of these incidents is unknown. A single container could be a catastrophe in the wrong place at the wrong time, endangering marine navigation as well as the environment. At the same time the growing worldwide economy demands bigger ships, operational efficiency, limited port time and optimised lashing gear. This has led to the start of the Lashing@Sea project to optimize cargo-securing performance, both from a safety and efficiency point of view.

Participants
To achieve this objective a consortium is formed by: Bluestar Ship Management, CMA-CGM, Danaos Shipping, NYK, Holwerda, Norfolk line, Royal Wagenborg, Spliethoff/Biglift, ABS, Bureau Veritas, DNV, Germanischer Lloyd, Lloyds Register, German Lashing, SEC, MacGREGOR, Amarcon, MaxControl, BMT de Beer, Dutch Ministry of Transport and MARIN. The project is supported and co-funded by the Dutch Maritime Innovation board.

Methods
Data will be collected and analyzed in full-scale measurement campaigns on several different vessels, to verify the validity of design assumptions, rules and guidelines and the effect of weather routing and possible over lashing. Parameters that are addressed include wave-induced ship accelerations, additional accelerations due to whipping, bow and stern slamming, container stack flexibility and cargo hatch motions. The results are compared to calculated values and loads occurring in the container stacks, twist locks and lashings. With the comparisons the underlying mechanisms will be investigated to identify how improvements to the current practice can best be achieved both for safety and efficiency.

Issues
For flag states and class societies one of the main questions will be to assess if the current rules, guidelines and specifications for containers still apply for the new generation of vessels. Based on the gained knowledge, class societies and lashing gear manufacturers may improve their rules and products. For operators, an important issue is the investigation concerning weather dependent lashing and routing. In the project the sensitivity of cargo securing loads to wave conditions and the accuracy of weather predictions will be investigated. Health and safety aspects for lashing crews and ship crews are an integrated part of this innovation project.
