Safety problems of anchoring in restricted areas in extreme hydrometeorological conditions

The aim of the following article is to analyse the lying of a vessel at anchor in extreme hydrometeorological conditions. As an example it describes the situation of the Panamax type bulk carrier anchoring in Prince Rupert harbour restricted area. The investigation takes into consideration the impact of strong wind on the safety of anchoring in sheltered waters. The presented calculations concern problems of slewing which result in changes of heading. The analysis also includes a description of the wind and current forces. The final part focuses on conclusions whose aim is to improve anchoring safety standards in areas managed by harbour authorities.
