FORESHORE LEADING LIGHTS OPTIONS STUDY

PRDW was requested by SIP Project Managers to carry out an assessment of options for the repositioning of the Port of Cape Town foreshore leading lights in order to accommodate development of the foreshore area. The leading lights are used for vessel navigation for vessels entering and departing Duncan Dock.

The study involved the completion of a full bridge ship simulation to verify that the proposed leading light configurations did not reduce the functionality of the aid to navigation and provided a suitable margin of safety. The full bridge simulation was undertaken considering multiple vessel classes for multiple leading light configurations.

The objectives of the study were:

• To determine the existing leading light requirements
• To investigate layout options for the repositioning of the leading light structures which will result in an increase in the vertical building restriction for the development
• To determine the new vertical building restrictions of the proposed solution
• To verify the preferred solution in a full mission ship simulator considering a range of vessels and conditions

On completion of the studies for the re-positioning of the leading lights, PRDW was requested to specify, request and adjudicate quotations and monitor construction and installation of the new leading light structures and lights.

The new structures and leading lights were successfully constructed and installed and have been operational since January 2015.
