Paragraph 13 I1

The Harbour Authority shall not in the exercise of the powers granted by this Order interfere with any marks, lights or other navigational aids in the river without the agreement of the PLA, and shall ensure that access to such aids remains available during and following construction of any tidal works.

The Harbour Authority shall provide at any tidal works, or shall afford reasonable facilities at such works (including an electricity supply) for the PLA to provide at the Harbour Authority’s cost, from time to time, such navigational lights, signals, radar or other apparatus for the benefit, control and direction of navigation as the PLA may deem necessary by reason of the construction of any tidal works, and shall ensure that access remains available to apparatus during and following construction of such works.

Without prejudice to section 133 of the 1968 Act (Lights detrimental to navigation), the Harbour Authority shall comply with the directions of the Harbour Master from time to time with regard to the lighting on the tidal works or within London Gateway Port, or the screening of such lighting, so as to ensure that it is not a hazard to navigation on the river.
