Whenever in connection with construction or operation of any part of a port system, any municipal port authority shall determine that it is necessary that any such facilities, which now are, or hereafter may be, located in, on, along, over or under any such real property, should be relocated in such real property, or should be removed therefrom, the public utility owning or operating such facilities shall relocate or remove the same in accordance with the order of the municipal port authority, provided, however, that the cost and expenses of such relocation or removal, including the cost of installing such facilities in a new location, or new locations, and the cost of any lands or any rights or interest in lands, or any other rights acquired to accomplish such relocation or removal, less the cost of any lands or any rights or interests in lands or any other rights of the public utility paid to the public utility in connection with the relocation or removal of such property, shall be paid by the municipal port authority and may be included in the cost of such port system. In case of any such relocation or removal of facilities, as aforesaid, the public utility owning or operating the same, its successors or assigns, may maintain and operate such facilities, with the necessary appurtenances, in the new location or new locations for as long a period, and upon the same terms and conditions, as it had the right to maintain and operate such facilities in their former location.
