ClassNK has introduced new guidelines for the container shipping industry aimed at enhancing stowage efficiency while ensuring safety against cargo collapse. These updated protocols utilize advanced technologies in weather forecasting, ship motion analysis, and digital twin technology. The new documents include the ‘Guidelines for Maritime Cargo Safety Based on Weather Forecasts,’ the ‘Guidelines for Anti-Rolling Devices,’ and the revised ‘Guidelines for Container Stowage and Securing Arrangements (Edition 3.3).’ Collectively, they seek to elevate both safety and capacity in container shipping, tailoring stowage practices according to short-term weather conditions.
The ‘Guidelines for Maritime Cargo Safety Based on Weather Forecasts’ advocate for route selection based on metocean data, spotlighting the importance of understanding forecast uncertainties to enhance safety. By analyzing over one million AIS records alongside historical weather data through big data techniques, these guidelines set new technical standards for evaluating cargo safety and introduce standard assessment methodologies. They also propose a calculation system for adjusting load factors based on weather predictions.
The ‘Guidelines for Anti-Rolling Devices’ address the increasing use of technology to combat ship rolling motions, a growing concern as cargo collapse risks rise. While these devices are becoming more common, uniform safety standards have yet to be established. This guideline outlines technical and inspection criteria necessary for deployment, drawing from previous experiences with parametric roll challenges.
Lastly, the revised ‘Guidelines for Container Stowage and Securing Arrangements’ reflect changes to incorporate weather forecasting and anti-rolling systems into current practices. This edition updates protocols to align with the complexities of modern container vessel operations. Interested parties can access the guidelines through ClassNK’s website upon registration. ClassNK is dedicated to promoting safe maritime practices in varied operational conditions through these comprehensive guidelines.
