Berth operators

Table 15.15 summarizes the preeautions to be followed by the berth operator for the transfer of dangerous bulk liquids. 

Berth operator should possess a supplier s certificate for any hose forming part of the pipeline confirming that tests have shown it is unlikely to burst in service. 

Prior to the transfer the berth operator and master should agree maximum loading or unloading rate. Berth operator to check periodically these are not exceeded. 

Berth operator to take reasonably practicable steps to control flammable or toxic gas escapes (e.g. hose support, flange couplings liquid- or gas-tight, drip trays). 

At the completion of the transfer of dangerous liquids the berth operator should render pipework, valves and associated equipment safe valves and tanks should be closed and shore pipeline blanked off. 

If you are a berth operator or terminal operator you will carry out dock operations at specific berths or on a terminal. You may own the berths or terminal, or you may lease them. In some cases you will simply be allowed to use them by the SHA, dock company or dock operator. You may employ dockworkers and be a stevedoring company, or you may make use of stevedores or workers from other labour suppliers.

Loads monitoring has another economic aspect. The seabed protection in the form of mattress, made of single elements, pinned and tight together with ropes, should be repaired immediately after the damage of a few elements because the next excess of loads can result in extensive damage. The cost of not detected repair can include replacement of several dozen elements and delays in berth operation. 

The loads monitoring system presented in the paper operated on line allows for the detection of all emergency situations, when ship master uses the power of propellers and thrusters over the permissible limits. This is the most important factor in the prediction of the condition of seabed protection made as geotextile sand filled bags mattresses. It can save maintenance costs related to the replacement of wide area of damaged elements and are the most important for a modern port as allows avoiding the delay in the berth operation. 

The wide variety of duties (e.g. pilot boarding arrangements, directing the vessels for the specific ETA, communicating with dock masters/berth operators, etc.) to the VTS officer seriously reducing proactivity in order to shipping safety. 

Mooring Mooring during berthing operations is normally undertaken in a conventional manner using rope mooring lines, fairleads, bollards and winches.
