Designing of mooring positioning system for an existing salvage ship

In designing the mooring positioning system of the ship two basic requirements for limitation of the ship displacements and mooring wire strength are to be complied with. Apart from these conditions, additional technical service requirements are also imposed. It is quite easy to observe the additional requirements for the mooring positioning system to be fitted on a new ship. However, ensuring compliance with the requirements for the existing ship, especially especially small one, is a difficult task and therefore some optimizing calculations are then necessary. This paper describes design of the mooring positioning system for a small salvage ship. Working out of the project required the system to be adapted to the ship parameters.
