The recommended guideline for avoiding the risk of electrostatic potential in a mist produced by using oil and water during Crude Oil Washing operations is that:

Before washing begins, any tank that is to be used as a source of oil for Crude Oil Washing should be partly discharged to remove any water that has settled out during the voyage. The discharge of a layer of at least 1 metres necessary for this purpose.

If a slop tank is to be used to supply oil to drive a Crude Oil Washing operation in a cargo tank, then that slop tank must not have contained slops with a water content of more than 2 %.

As washing begins, any water observed in the stream should be diverted to a slop tank, before Crude Oil Washing of any cargo compartment is commenced.

Crude Oil Washing, where the oil source is stored in a slop tank or other tank that has previously contained slops, should be avoided.

The current test includes Seagull CES questions on the topic of «Deck, Management, Oil Tanker». These questions are designed to assess the competence of specialists in preventing accidents related to transport safety and can also be used for self-assessment.

The «Management» subject provides both theoretical and practical knowledge essential for advanced training on any type of vessel. Proficiency in this area is a direct indicator of an employee's competence in their specific role on a vessel. On an oil tanker, the Deck Management Officer is responsible for a wide range of duties that ensure the vessel's safe operation and compliance with international standards, including command, navigation, and cargo management. The specific responsibilities for deck management on an oil tanker can vary depending on company policies, as well as international regulations and standards governing maritime safety and operations at sea.
