REDUCING CONTAINER LOSSES – OPERATIONAL GUIDANCE
Published: 21 September 2022
When a vessel experiences adverse weather conditions, it is likely to face various kinds of dangerous phenomena that can lead to excessive rolling motions. For container vessels excessive rolling can result in stowage collapse and loss of containers which may endanger both the safety of the vessel and the environment – and potentially become very costly for a shipowner.
In situations where a vessel encounters excessive rolling, swift actions are required and just a minor course, or speed adjustment, may be enough to prevent the situation from developing dangerously. However, maintaining situational awareness and making the right decision in an often rapid-changing and stressful situation can be difficult. Furthermore, various support tools may be lengthy and impractical to use. Therefore, Britannia P&I, in collaboration with Waves Group and Lloyd’s Register, has developed simple onboard guidance to assist the bridge team of container ships in identifying the conditions that may lead to parametric or synchronous rolling and in taking the appropriate actions to mitigate against these risks.
The operational guidance is freely available on our webpage and covers container vessels from 3,000 up to 23,000 TEU in size. When printed, this information can be placed on the bridge as an easy-to-use support tool to determine what change in the vessel’s speed and heading may be required to bring it to a safer operating condition.
