What is commonly included in a barrier aside from a void space?

A barrier on a tanker typically consists of elements designed to enhance safety and prevent the release of hazardous substances, particularly in the event of a hull breach. In addition to void spaces, which serve as structural reinforcement and a safety buffer to absorb pressures, barriers can also include various operational components.

Ballast is included for the purpose of enhancing the vessel’s stability and safety, especially when the tanker is not fully loaded. It is essential for maintaining a proper trim and offsetting the potential for rolling or pitching.

Pumprooms are integral to the functioning of the tanker, as they house the machinery necessary for managing the cargo and ballast systems. Having them positioned within the barrier area helps in safeguarding the equipment from potential damage during incidents.

Empty cargo tanks, when not in use, are treated as part of the barrier system. They allow for flexibility in handling different types of cargo while providing additional safety space.

Thus, a comprehensive approach to safety is reflected in the inclusion of ballast, pumprooms, and empty cargo tanks alongside void spaces in barriers. This not only maximizes structural integrity but also enhances operational safety.
