Annex - Location of Tank Washing Heaters - Interpretation of Paragraph 4.1.6 of the Revised COW Specifications

  4.1.6 On new oil tankers the steam heater referred to shall be located outside of the machinery spaces if it has permanent piping connection to the crude oil washing system. If the heater and wash water supply source are located in the machinery spaces and so arranged that they can only be connected to the tank washing system when that system is completely and unmistakably disconnected from the cargo system, the heater and the supply source are not regarded as part of the crude oil washing system. The connection arrangements to the tank washing system must be arranged in the cargo tank area. On an existing oil tanker with an existing steam heater located in the machinery spaces no additional isolation will be required other than that which isolates the crude oil washing system from the machinery spaces.
