67.—(1) The undertaker must provide guard vessels to be positioned both upstream and downstream of the relevant part of the river during any tidal works and temporary closures of the river.

(2) The number and position of any such guard vessels must be agreed in advance in writing with the Port Authority, such agreement not to be unreasonably delayed or withheld.

(3) The undertaker must, at or near any tidal work, exhibit such lights, lay down such buoys and take such other steps for preventing danger to navigation as the Port Authority may from time to time reasonably require.

(4) All vessels must, at all relevant times, display lights, shapes and signals in accordance with all applicable law, regulation and international conventions.

(5) The Port Authority must give the undertaker not less than 20 business days’ written notice of a requirement under sub-paragraph (3) except in the case of increased risk or emergency when the Port Authority must give such notice as is reasonably practicable.

(6) The undertaker must comply with any directions of the Port Authority given from time to time with regard to the lighting of tidal works, or the screening of such lighting, so as to ensure that it is not a hazard to navigation on the river.
