This conceptual design for vertical and horizontal navigation requirements should be optimised or assessed in greater
detail by using ship manoeuvring simulation in the next steps of the design process. These simulations can also be
used to assess the requirements for manoeuvring in difficult situations, such as the usual south-west monsoon
conditions, with heavy cross winds, heavy swell or a combination of both.
9.4.3. Aids to navigation
For this first approach to determine the navigational marks and aids, IALA (The International Association of Marine
Aids to Navigation and Lighthouse Authorities) recommendations have been considered to design it. Also, opinions
from navigational and Port Authority experts have been collected.
The following navigational marks have been defined:
• Starboard and port marks to be used in the entrance to the port.
• Special buoys set near south breakwater and south west breakwater to signal the area is not planned for
dredging in Phase 1.
• Leading lights to indicate the navigation course.
• Cardinal marks to indicate depth limitation in approach channel.
Further information on navigational marks is included in Drawing-05.
Vessel Traffic Management System (VTMS) is also expected to be necessary for a proper operation of the port. This
system should include at least a Radar, an Automated Identification System (AIS) base station, a VHF radio system,
and a control station to integrate all components of the system.
9.5. DREDGING AND RECLAMATION
9.5.1. Introduction
In order to select suitable dredging equipment, it is necessary to take into account considerations about soil, dredging
depth, environmental conditions, logistic factors, etc. This proposed methodology and equipment is prepared based
on the information available at this stage but the final approach has to be developed by the contractors who are
experienced and innovative in the field of marine dredging operation.
9.5.2. Dredging works
The total quantity of material to be dredged has been obtained by comparing the current bathymetry to the final
geometry of the sea bottom as shown in Drawing-05: Dredging Plan:
