Siport21 recently presented the ‘Methodology to Analyze the Moored Ship Behaviour Due to Passing Ships Effects’ during the ‘Hydrodynamic and Simulation Applied to Inland Waterways and Port Approaches’ conference organised by Société Hydrotechnique de France in Paris.
This methodology was applied to analyse the feasibility of a new terminal from an operational point of view.
The analysis combined calculations with four different numerical models: fast-time manoeuvring simulation, ship-ship interaction, dynamic mooring analysis and real-time manoeuvring simulator.
The aim of the study was to analyse the effects of passing ships, selected from traffic data in the area, on moored vessels at the new terminal.
In view of all the previous results, different alternatives were proposed in order to improve the conditions obtained in the analysis and raise the operation limits.
A new solid bulk terminal is planned to operate in the Port of Barcelona, Spain, and before it starts operating, this methodology has been applied in the new terminal.
The design vessels to operate in the terminal are two bulk carriers; 230 metres and 186 metres, respectively. These ships will be moored at the berth simultaneously and may be affected by the passing ship effect (car-carriers and tankers sailing to the inner basin).
The access manoeuvres of the vessels were analysed in different scenarios, in order to assess the operative limits, passing speed and distance required.
Afterwards, the effects were analysed of suction forces and moments generated by the passing vessel on the moored vessels. Finally, Siport21 carried out recommendations for minimising these effects and optimising their operations.
Fact File: Siport21 is a pioneer in the installation and implementation of numerical ship manoeuvring models and ship manoeuvring simulators in a private company in Spain. Since 1999, Siport21 has developed approximately 700 technical studies spread out over almost all the Spanish coast and they have worked in 33 other countries.
