Ro-Ro Ramps

Alternatives Study for the development of Isla Verde and Simulation Maneuvers at the Ro-Ro Ramp in the Port of Algeciras (Spain)

Location: Algeciras Bay, Cadiz (Spain)
Client: Algeciras Bay Port Authority

Project Objectives

  • Assess the operation and safety of maritime access to new facilities in relation to the navigation area, as well as detect eventual interferences in the manoeuvres.
  • Analyze access manoeuvres to the Ro-Ro Isla Verde ramp in order to determine the limit operating conditions for these vessels, analyze the interference with adjacent berths and define the most appropriate manoeuvring strategy.

The ship reference models were:

  • Container ship, 347 m length and 42.9 m beam (reference Maersk class “S”) and 42.9 m beam (reference Maersk class “S”)
  • Container ship, 397 m length and 56 m beam (reference “Emma Maersk”)
  • Ro-Ro Superfast 185 m length and 25.2 m beam

Tools and Methodology

For this purpose, the manoeuvring numerical model SHIPMA was used. This is a numerical autopilot model for ship manoeuvring under the influence of wind, waves and current developed by Delft Hydraulics and MARIN (The Netherlands).

Also, a Real-time Ship Bridge Simulator (MERMAID 500 model developed by MARIN-MSCN (The Netherlands)) was used. This tool is property of Siport21 and located in Madrid. This is the only privately-owned simulator of this kind in Spain.The analysis was carried out following the methodology described by PIANC (International Navigation Association).
