Ports) which may reasonably be incurred by or occasioned to A. B. Ports by reason of or arising from or in connection with—
(a)the perusal of plans and the inspection of any of the tidal works by A. B. Ports or its duly authorised representative;
(b)the carrying out of such surveys, inspections, tests and sampling within the river as A. B.

B. Ports;
(c)the construction or maintenance of any of the tidal works, the failure of any of the tidal works or the undertaking by A. B. Ports of works or measures to prevent or remedy danger or impediment to navigation or damage to any property of A. B. Ports arising from such construction, exercise or failure;
(d)any act or omission of the undertaker or their servants or agents whilst engaged in the construction of any of the tidal works or the exercise of the powers conferred by article 10.

(3) Nothing in this paragraph shall impose any liability on the undertaker to the extent that any losses, costs, charges, damages, expenses, claims or demands referred to in sub-paragraph (1) or (2) are attributable to negligence on the part of A. B. Ports or of any person in its employ or of its contractors or agents.
(4) A. B. Ports shall give to the undertaker notice in writing of any claim or demand for which the undertaker may be liable under this paragraph and no settlement or compromise of any such claim or demand shall be made without the consent in writing of the undertaker.
