PART 2Specific Provisions (continued)
DIVISION 2Noxious Liquid Substances and Dangerous Chemicals (continued)
SUBDIVISION 8Transfer Operations
72 This Subdivision applies in respect of vessels only when they are in waters under Canadian jurisdiction or, if a transfer operation to which this Subdivision applies does not involve a noxious liquid substance, only when they are in Canadian waters.
73 If a vessel or a handling facility engages in a transfer operation, the vessel’s master and the operator of the facility must, before and during the transfer operation, have the means for two-way voice communication on a continuing basis that enables the supervisor on board the vessel and the supervisor at the facility or on board the other vessel
(a) to communicate immediately as the need arises; and
(b) to direct the immediate shutdown of the transfer operation in case of an emergency.
74 (1) If a vessel or a handling facility engages in a transfer operation between sunset and sunrise, the vessel’s master and the operator of the facility must ensure that illumination is provided that has
(2) For the purposes of subsection (1), lighting intensity is to be measured on a horizontal plane 1 m above the walking surface of the facility or the working deck of the vessel, as applicable.
Marginal note:Transfer conduits
Marginal note:Test certificates
(2) If a transfer conduit used in a transfer operation is part of a vessel’s equipment, the vessel’s master must keep on board the test certificate for the hydrostatic test.
Marginal note:Manufacturer’s specifications
(3) The owner of a transfer conduit that is used in a transfer operation must ensure that the conduit is used, maintained, tested and replaced in accordance with the manufacturer’s specifications.
(4) If a transfer conduit or a connection leaks during a transfer operation, the supervisor on board the vessel and the supervisor at the handling facility or on board the other vessel must, as soon as feasible, slow down or stop the operation to remove the pressure from the conduit or connection.
Marginal note:Requirements for transfer operations — vessels
76 The authorized representative of a vessel that engages in a transfer operation must ensure that it is supervised on board the vessel by a person who is required to be part of the complement of the vessel
- SOR/2013-68, s. 12
Marginal note:Duties of supervisors of transfer operations — vessels
(a) the vessel is secured, having regard to the weather and the tidal and current conditions, and the mooring lines are tended so that the movement of the vessel does not damage the transfer conduit or its connections;
(b) transfer procedures are established with the concurrence of the supervisor of the transfer operation at the handling facility or on board the other vessel, as the case may be, with respect to
(i) the rates of flow and pressures for the transferred liquid,
(ii) the reduction of rates of flow and pressures where required to avoid an overflow of the tanks,
(iii) the time required to stop the transfer operation under normal conditions,
(iv) the time required to shut down the transfer operation under emergency conditions, and
(v) the communication signals for the transfer operation, including
(c) the supervisor of the transfer operation at the handling facility or on board the other vessel, as the case may be, has reported readiness for the commencement of the transfer operation;
(d) the person who is on duty on board the vessel in respect of the transfer operation is fully conversant with the communication signals, maintains watch over the vessel’s tanks to ensure that they do not overflow, and maintains continuous communication with that person’s counterpart at the handling facility or on board the other vessel, as the case may be;
(e) the manifold valves and tank valves on the vessel are not closed until the relevant pumps are stopped, if the closing of the valves would cause dangerous over-pressurization of the pumping system;
(f) the rate of flow is reduced when the tanks are being topped off;
(g) the supervisor of the transfer operation at the handling facility or on board the other vessel, as the case may be, is given sufficient notice of the stopping of the transfer operation to permit them to take the necessary action to reduce the rate of flow or pressure in a safe and efficient manner;
(h) the following measures are taken to prevent the discharge of a noxious liquid substance or dangerous chemical:
(i) all cargo manifold connections that are not being used in the transfer operation are securely closed and fitted with blank flanges or other equivalent means of closure,
(ii) all overboard discharge valves are securely closed and marked to indicate that they are not to be opened during the transfer operation, and
(iii) all scuppers are plugged;
(i) a supply of absorbent material is readily available near every transfer conduit to facilitate the clean-up of any minor spillage of noxious liquid substances or dangerous chemicals that may occur on the vessel or on the shore;
(j) all transfer conduits that are used in the transfer operation are supported to prevent the conduits and their connections from being subjected to any strain that might cause damage to them or cause the conduits to become disconnected;
(k) all systems, equipment, personnel and information necessary for the safety of the transfer are in readiness before the transfer operation begins;
(l) towing-off wires are positioned fore and aft and are ready for use without adjustment if it is necessary to tow the vessel away;
(m) the transfer of a flammable cargo and the gas-freeing that follows the unloading of a flammable cargo is stopped when an electrical storm is in the immediate vicinity of the vessel;
(n) no work is carried out in the cargo tank area without the authorization of the vessel’s master;
(o) the valves in the vent system are checked for the correct setting and the flame arresters are examined for cleanliness and proper installation;
(p) articulated loading booms, if used, are checked for undue strain;
(q) the pump room ventilation is running and all precautions for that area are observed;
(r) a tank that is required to be kept in an inert state (a state in which the oxygen content of the tank must be below a specified level), and to maintain a small positive pressure at all times, has a supply of inert gas available to maintain its inert state during the transfer operation;
(s) during loading,
(i) the tank concerned is free of flammable or toxic vapours or residues,
(ii) the free end of the loading hose is securely lashed to the inside of the tank to prevent movement,
(iii) all flanges and gaskets are suitable for the purpose, and
(iv) all tank openings, other than those that are in use, are closed; and
(t) all reasonable precautions are taken to avoid the discharge of a noxious liquid substance or dangerous chemical.
Marginal note:Duties of supervisors of transfer operations — facilities
(2) The supervisor of a transfer operation at a handling facility must ensure that
(a) the supervisor of the transfer operation on board the vessel has reported readiness for the transfer operation to begin;
(b) continuous communication is maintained with the supervisor on board the vessel; and
(c) the manifold valves and the tank valves at the handling facility are not closed until the relevant pumps are stopped, if the closing of the valves would cause dangerous over-pressurization of the pumping system.
