Where can fuel oil sounding tubes and access openings for fuel oil tanks on cargo vessels be located?

Fuel oil sounding tubes and access openings for fuel oil tanks on cargo vessels are generally found in cargo holds. This location is strategically advantageous because it allows for easy access during cargo operations, inspections, and maintenance. The cargo hold is an area designed to accommodate heavy equipment and machinery, making it feasible to store and manage fuel oil necessary for vessel operations.

In contrast, areas such as laundries, crew lounges, and washrooms are designated for the comfort and amenities of the crew and passengers. These spaces do not serve functional purposes related to the operation of the vessel's fuel systems and would not facilitate the required access to tanks for monitoring or maintenance. Therefore, locating fuel oil sounding tubes in the cargo holds ensures that they are easily accessible for necessary operational activities while remaining compliant with safety and regulatory standards.
