(1) The conservator may remove, or cause to be removed, either on his own or through external agency or through a port officer, any obstruction in any part of a port, which in his opinion obstructs the operation of a port or part thereof or any other work on any part of the shore or bank within the port limits.
(2) The owner of any such obstruction shall be liable to pay the reasonable expenses of the removal thereof.
(3) If the owner of any such obstruction fails to pay the reasonable expenses incurred in the removal thereof, the conservator may sell the vessels, wreck, material or any other thing forming the obstruction in public auction and recover expenses incurred for such removal from the proceeds of the sale, and shall pay the surplus of such proceeds, or deliver the unsold parts of the obstruction, to the person entitled to receive the same and if no such person is available, the conservator shall cause the same to be kept and deposited in such manner as the Government directs.
(4) The conservator may, if necessary, from time to time, realise the expenses of keeping the obstruction, together with the expenses of sale, by a further sale of such part of the obstruction as may remain unsold.
(5) If the obstruction exists on account of any permit, grant, licence or other lawful instrument issued by the Government, then the conservator shall report the same to the Government, and, with the previous sanction of the Government, cause the same to be removed or altered in such manner, making reasonable compensation to the owner of such obstruction, to be determined on the basis of such factors, as may be prescribed by the appropriate Government.
