(1)If, on the application of any public utility undertakers who carry on a dock or harbour undertaking the appropriate department so order, the preceding provisions of this Part of this Act relating to the provision of air-raid shelter for persons employed by public utility undertakers, shall apply in relation to the undertakers carrying on the undertaking as if all persons likely to be found during air-raids in the dock or harbour, or any such part thereof as may- be specified in the order, were persons employed by the undertakers; and where any such order is made—
(a)the order may contain such incidental and consequential provisions as the appropriate department thinks proper, including provisions authorising the undertakers, notwithstanding anything in any contract or in any enactment or order relating to them, to do such of the following things as may be specified in the order, that is to say—
(i)to make such increases in their charges as may be specified in the order;

(iii)to borrow such money on such terms as to security and otherwise as may be specified in the order;
(b)the provisions of Part III of this Act relating to the provision of air-raid shelter shall not apply in relation to any factories or commercial buildings situate in the dock or harbour or, as the case may be, in the part thereof specified in the order; and
