What are the two types of shoring used onboard?

The correct answer identifies wood and steel as the two primary types of shoring used onboard. This is because both wood and steel have unique properties that make them suitable for providing structural support during damage control operations.

Wood is commonly used in shoring due to its availability, ease of handling, and versatility. It can be cut and shaped to fit various dimensions and can effectively bear loads when properly assembled. Wood shoring is particularly valuable in situations where access or weight limits are considerations.

Steel, on the other hand, offers superior strength compared to wood, making it ideal for heavy loads or situations requiring robust support. Steel shoring can withstand greater forces and is often used in conjunction with wood to reinforce structures during repair operations.

The combination of wood and steel provides a balanced approach, offering both flexibility and strength, which is essential for effective damage control in various conditions onboard a vessel.
