The biggest risk of cargo escape occurs at the ship/shore manifold area. Reliable equipment at the jetty is vital for safe transfer of cargo between the ship and shore.

 

Maintenance of this equipment is important due to the harsh environmental conditions that are experienced. However, difficulties with access and the need to interface with shipping operators will often make maintenance more difficult.

 

In many countries, it is a legal requirement to keep records of maintenance work that is carried out. These records should, as a minimum, consist of the inspection results, measurements and the tests that were carried out. The results should also itemise what work was carried out and whether any replacements were required. Monitoring this information is necessary as it is an indication of the deterioration rates, failure rates and the general standard of the work being carried out.

 

This book provides information on the basic function, failure, inspection, maintenance and repair of all the key equipment items and systems. It is not intended to provide guidance on safety management procedures or to replace the manufacturers’ instruction manuals. However, it is designed to provide a description of a typical jetty and the likely faults that may occur if maintenance work is not carried out regularly.
