Paragraph 18 Facilities for navigationI1

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

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

The undertaker must comply with the directions of the harbour master from time to time with regard to the lighting on the tidal works or within the harbour, or the screening of such lighting, so as to ensure safe navigation on the river.
