OIL IN NAVIGABLE WATERS ACT
An Act to implement the terms of the International Convention for the prevention of pollution of the Sea by Oil 1954 to 1962 and to make provisions for such prevention in the navigable waters of Nigeria.
[COMMENCEMENT] [22nd April 1968]
(1) If any oil to which this section applies is discharged from a Nigerian ship into a part of the sea which, in relation to that ship, is a prohibited sea area, or if any mixture containing not less than 100 parts of oil to which this section applies is discharged from such a ship into such a part of the sea, the owner or master of the ship shall, subject to the provisions of this Act, be guilty of an offence under this section.
(2) This section applies—
(a) to crude oil, fuel and lubricating oil; and
(b) to heavy diesel oil, and shall also apply to any other description of oil which may be prescribed under this subsection by order made by the Minister, having regard to the provisions of any subsequent Convention in so far as it relates to the prevention of pollution of the sea by oil, or having regard to the persistent character of oil of that description and the likelihood that it would cause pollution if discharged from a ship into a prohibited sea area.
(3) The Minister may, by regulations made under this subsection, make exceptions from the operation of subsection (1) of this section, either absolutely or subject to any prescribed conditions, and either generally or as respects particular classes of ships, or in relation to particular descriptions of oil or mixtures in prescribed circumstances, or in relation to particular areas of the sea.
(4) In this Act, “subsequent Convention” means any Convention subsequent to the Convention of 1954 to 1962 being a Convention relating to the aforesaid Convention, and accepted by the Federal Government of Nigeria.
(1) For the purposes of this Act the areas of the sea designated by or in accordance with this section shall be prohibited sea areas.
(2) Subject to the following provisions of this section, the areas specified in the Schedule to this Act shall be prohibited sea areas.
(3) The Minister, if he considers it necessary to do so for the purpose of protecting the coast and territorial waters of Nigeria from pollution by oil, may by order designate any area of the sea outside the territorial waters of Nigeria and outside the areas specified in the Schedule to this Act as a prohibited sea area.
(4) For the purpose of giving effect to any variation of the prohibited zones referred to in the Convention of 1954 to 1962, in accordance with the provisions of that Convention or of any subsequent Convention, the Minister may by order vary any of the areas specified in the Schedule to this Act or declare that any area specified in that Schedule shall cease to be included therein.
(5) For the purpose of giving effect to any subsequent Convention, the Minister may by order designate as a prohibited sea area, any area of the sea, outside the territorial waters of Nigeria, which, apart from the order, is not a prohibited sea area.
(6) The power of the Minister under subsection (4) or (5) of this section shall be exercisable either generally or in relation to different classes of vessels or different circumstances or both.
(1) If any oil or mixture containing oil is discharged into waters to which this section applies from any vessel, or from any place on land, or from any apparatus used for transferring oil from or to any vessel (whether to or from a place on land or to or from another vessel), then subject to the provisions of this Act—
(a) if the discharge is from a vessel, the owner or master of the vessel; or
(b) if the discharge is from a place on land, the occupier of that place; or
(c) if the discharge is from apparatus used for transferring oil from or to a vessel, the person in charge of the apparatus, is guilty of an offence under this section.
(2) This section applies to the following waters, that is—
(a) the whole of the sea within the seaward limits of the territorial waters of Nigeria; and
(b) all other waters (including inland waters) which are within those limits and are navigable by sea-going ships.
(3) The harbour authority may appoint a place within its jurisdiction where the ballast water of vessels in which a cargo of dangerous petroleum has been carried may be discharged into the waters of the harbour, at such times, and subject to such conditions, as the authority may determine, and, where a place is so appointed, the discharge of ballast water from such a vessel shall not constitute an offence under this section, if the ballast water is discharged at that place and at a time and in accordance with the conditions so determined and the ballast water contains no oil other than dangerous petroleum.
(4) In subsection (3) of this section, “dangerous petroleum” has the same meaning as in the Petroleum Act.
(1) Where a person is charged with an offence under section 1 of this Act, or is charged with an offence under section 3 of this Act as the owner or master of a vessel, it shall be a defence to prove that the oil or mixture in question was discharged for the purpose of securing the safety of any vessel, or of preventing damage to any vessel or cargo or of saving life:
Provided that a defence under this subsection shall not have effect if the court is satisfied that the discharge of the oil or mixture was not necessary for the purpose alleged in the defence or was not a reasonable step to take in the circumstances.
(2) Where a person is charged as mentioned in subsection (1) of this section, it shall also be a defence to prove—
(a) that the oil or mixture escaped in consequence of damage to the vessel, and that as soon as practicable after the damage occurred all reasonable steps were taken for preventing, or (if it could not be prevented) for stopping or reducing, the escape of oil or mixture; or
(b) that the oil or mixture escaped by reason of leakage, that the leakage was not due to any want of reasonable care, and that as soon as practicable after the escape was discovered all reasonable steps were taken for stopping or reducing it.
(3) Where a person is charged with an offence under section 3 of this Act as the occupier of a place on land, or as the person in charge of any apparatus, from which oil or a mixture containing oil is alleged to have escaped, it shall be a defence to prove that the escape of the oil or mixture was not due to any want of reasonable care, and that as soon as practicable after the escape was discovered all reasonable steps were taken for stopping or reducing it.
(4) Without prejudice to subsection (3) of this section, it shall be a defence for the occupier of a place on land, who is charged with an offence under the last preceding section, to prove that the discharge was caused by the act of a person who was in that place without the permission (express or implied) of the occupier.
(5) Where a person is charged with an offence under section 3 of this Act in respect of the discharge of a mixture containing oil from a place on land, it shall (without prejudice to any other defence under this section) be a defence to prove—
(a) that the oil was contained in an effluent produced by operations for the refining of oil;
(b) that it was not reasonably practicable to dispose of the effluent otherwise than by discharging it into waters to which the last preceding section applies; and
(c) that all reasonably practicable steps had been taken for eliminating oil from the effluent:
Provided that a defence under this subsection shall not have effect if it is proved that, at a time to which the charge relates, the surface of the waters into which the mixture was discharged from the place in question, or land adjacent to those waters, was fouled by oil, unless the court is satisfied that the fouling was not caused, or contributed to, by oil contained in any effluent discharged at or before that time from that place.
(6) Where any oil, or mixture containing oil, is discharged in consequence of—
(a) the exercise of any power conferred by sections 273 and 275 of the Merchant Shipping Act (which relate to the removal of wrecks by the Receiver of Wreck);
(b) the exercise, for the purpose of preventing an obstruction or danger to navigation, of any power to dispose of sunk, stranded or abandoned vessels which is exercisable by the harbour authority, and apart from this subsection, the person exercising the power under the said sections 273 and 275 or, as the case may be, the harbour authority exercising the power, (or a person employed by or acting on behalf of that person or authority) is guilty of an offence under section 1 of this Act or under section 3 of this Act, in respect of that discharge, the authority or person shall not be convicted of that offence unless it is shown that it or he failed to take such steps (if any) as were reasonable in the circumstances for preventing, stopping or reducing the discharge.
(1) For the purpose of preventing or reducing discharges of oil and mixtures containing oil into the sea, the Minister may make regulations requiring Nigerian ships to be fitted with such equipment, and to comply with such other requirements, as may be prescribed.
(2) Without prejudice to the generality of subsection (1) of this section, where any regulations made thereunder require ships to be fitted with equipment of a prescribed description, the regulations may provide that equipment of that description—
(a) shall not be installed in a ship to which the regulations apply unless it is of a type tested and approved by a person appointed by the Minister;
(b) while installed in such a ship, shall not be treated as satisfying the requirements of the regulations unless, as such times as may be specified in the regulations, it is submitted for testing and approval by a person so appointed.
(3) The Minister may appoint persons to carry out tests for the purposes of any regulations made under this section, and, in respect of the carrying out of such tests, may charge such fees as may be prescribed by the regulations.
(4) Every surveyor of ships shall be taken to be a person appointed by the Minister to carry out tests for the purposes of any regulations made under this section, in so far as

(1) In loading, discharging or bunkering oil, all vessels shall take the following precautions—
(a) where no facilities exist for the proper draining of hoses, the ends should be suitably blanked;
(b) when hose connections are being made or broken, drip trays shall be used to catch any spillage;
(c) all scupper holes to which oil in the event of spillage would have access, shall be tightly plugged for the duration of the operations;
(d) care shall be taken to ensure that the vessel is securely moored so as to avoid any undue strain on the pipe connections between the vessel and the shore or between vessel and vessel;
(e) hoses and all other equipment to be used shall be inspected and where any damage is detected, such damage shall be repaired before commencing operations;
(f) any oil accidentally spilt on deck or on the quay, pier or jetty shall be immediately bailed up and disposed of into the cargo tank or bunkers or ashore;
(g) the means of communication between vessel and shore or between vessel and vessel shall be checked and all signals to be used thoroughly understood;
(h) when the loading of a tanker or tank barge is completed, all tank hatch lids shall be immediately secured and all other openings communicating to the tanks, other than those controlled by a relief valve, rendered impassable to oil.
(2) The following precautions shall be observed in relation to bunkering operations—
(a) the master of any ship being bunkered from any other vessel or from a shore installation shall appoint a responsible officer to personally supervise the bunkering operation;
(b) before bunkering commences—
(i) all air vent pipes shall be inspected to ensure that displaced air and gases can escape freely;
(ii) the master shall ensure that ullages or soundings are taken to determine the quantity of oil on board in order to ensure that the bunker space will accommodate the amount of the expected delivery;
(c) where one of the fuel storage tanks is set aside as an overflow tank it shall be the last to be filled;
(d) during bunkering operations frequent soundings shall be taken and the rate of the delivery shall be slowed down during “topping off”; and where possible, “topping off” of double bottom tanks shall be done from deep banks.
(3) Where fuel oil is being transferred from one space to another within a ship the following precautions shall be observed—
(a) care shall be taken to ensure that overboard discharge connections from the fuel oil transfer pumps are properly closed and secured against accidental overboard discharge;
(b) care shall be taken to ensure that—
(i) the air vent pipes of the settling tanks are free from blockages;
(ii) the overflow pipes leading from the settling tanks to fuel storage tanks are in order and that sounding arrangements or oil level indicating gear on the settling tanks do not allow the escape of oil in the event of accidental overfilling of the settling tanks.
(4) Where tanks used alternately for fuel oil and water ballast are being filled with such ballast the following precautions shall be observed—
(a) if a pump is used, the pump must be started before the sea valves are opened;
(b) during ballasting, all tanks shall be inspected to ensure that only the tanks which are intended as ballast are receiving water;
(c) on completion of ballasting, the sea valves must be closed before the pump is stopped (if used) so as to prevent the escape into the sea of any oil or any oil contaminated water which may be in the lines.
(5) In the engine rooms or other machinery spaces of tankers the following precautions shall be observed—
(a) a close watch shall be kept on the special oily bilge, gutter-ways or other arrangements provided to confine oil leakage from tank sides and mountings, fuel oil pumps and the like; and any accumulation of fuel oil shall be transferred to a bunker or settling tank well before risk or overflow to the ordinary bilges arises;
(b) trays beneath oil pumps, heaters and burners shall be kept clean so that any leakage will be immediately apparent and can be dealt with before it pollutes the ordinary engine room or boiler room bilges;
(c) all fuel oil pipes within the engine or boiler room, and especially those in which the oil is under pressure, shall be inspected regularly to ensure early detection of any leak which would result in contamination of the ordinary bilges with oil fuel.
(6) The master of any ship and the person in charge of any tank barge shall ensure that a careful inspection of the ship’s or barge’s hull is carried out at regular intervals for the purpose of detecting any leakage of oil.
(7) In addition to the foregoing provisions of this regulation, the master of a tanker shall observe the following precautions—
(a) before loading commences—
(i) all sea valves and deck overboard discharge valves on the oil and ballast lines shall be tightly closed;
(ii) all deck valves which are not to be used shall be properly closed and where practicable blanked off; and
(iii) all valves which are to be used shall be inspected to see that they are free and in good order;
(b) loading must begin at a slow rate and after loading has started the tanks which are being loaded shall be inspected and the water round the ship’s side shall also be inspected; and if loading is proceeding satisfactorily the rate may be gradually increased until the desired loading rate is obtained when a further inspection must be made but no more tanks shall be loaded at any one time than can be safely watched and controlled;
(c) the depth of oil in each cargo tank which is being loaded shall be constantly watched and the receiving rate shall be appropriately reduced towards the final stages of loading and to allow time for orderly control the slowing down of the receiving rate necessary during the “topping off” process should be anticipated and appropriate notice given to the staff in charge of the delivery; and after any tank valve has been closed, the liquid level in that tank shall be checked to ensure that the valve is properly closed;
(d) before discharging, all cargo deck line valves, sea valves and any stern loading and discharge valves which are not to be used, shall be inspected to ensure that they are tightly closed and where practicable such valves shall be set to the discharging position and checked to see that they are free and in good order;
(e) after hoses are connected no discharging shall commence until after the shore staff have indicated that they are ready to receive cargo; and where the back pressure in the shore line is such that there is a possibility of oil flowing from the shore to the ship, the ship’s valve at the shore connection shall not be opened until the pressure is equalised;
(f) at the commencement of discharging, the cargo pumps shall be started slowly and the working pressure gradually built up; but during this process a constant watch shall be kept on the discharge pressure in order to ensure that the shore receiving lines are clear and that an excessive pressure is not being built up in the cargo lines; and when the desired rate of discharge has been reached a further inspection shall be made of any stern or other discharge valves not in use, of the cargo, hose and hose connections and of the water round the ship’s side to see that no oil is escaping;
(g) at frequent intervals during the discharging operations conditions in the pump room, the operating pressure in the cargo system and possible points of leakage shall be inspected; and the ship shall always be prepared to stop loading at short notice.
