What is the primary concern addressed by installing dog wedges on watertight doors?

The primary concern addressed by installing dog wedges on watertight doors is wear prevention. Dog wedges are designed to hold watertight doors securely closed, preventing them from rattling or moving due to environmental factors or operational conditions. This secure closure minimizes the risk of wear that can occur from repeated opening and closing, as well as from the stresses imposed by water pressure on the seals of the door when it is shut. The integrity of watertight doors is crucial in maintaining compartmentalization within a vessel to prevent flooding; thus, ensuring they function without excessive wear maximizes their lifespan and effectiveness in fulfilling their role in safety and waterproofing.

While weather protection, access control, and separation of compartments are important considerations in the functionality of watertight doors, the main focus of installing dog wedges is to prevent wear and tear, ensuring that these doors can maintain a reliable seal and operate efficiently over time.
