Arrangements shall be made so that boiler soot blowers cannot be operated when the corresponding flue gas valve is open; (f) (i) a flue gas scrubber shall be fitted which will effectively cool the volume of gas specified in paragraph (c) and remove solids and sulphur combustion products. The cooling water arrangements shall be such that an adequate supply of water will always be available without interfering with any essential services on the ship. Provision shall be made for an alternative supply of cooling water; (ii) filters or equivalent devices shall be fitted to minimise the amount of water carried over to the inert gas blowers;(g) (i) at least 2 blowers shall be fitted which together shall be capable of delivering to the cargo tanks and slop tanks, at least the volume of gas required by paragraph (c). In a system provided with a gas generator, the Director may permit only one blower if that system is capable of delivering the total volume of gas required by paragraph (c) to the protected cargo tanks, on condition that sufficient spares and replacement parts for the blower and its prime mover are carried on board to enable any failure of the blower and its prime mover to be rectified by the ship's crew; (ii) 2 fuel oil pumps shall be fitted
