Ship Hatches
There are several types of marine hatches used on ships and other marine structures. Some of the most common types include:
Watertight hatches: these are hatches designed to prevent water from entering the compartment they are covering. They are commonly used to provide access to cargo holds, engine rooms, and other below-deck spaces.
Weathertight hatches: these hatches are designed to prevent the ingress of water from waves, spray, and rain. They are commonly used on the weather deck of ships to provide access to crew spaces and cargo holds.
Non-watertight hatches: these are hatches that are not designed to be watertight or weathertight. They are commonly used for access to non-critical spaces such as storage compartments and voids.
Ship hatches are used to close openings in the deck or hull of a ship, providing watertight seals to prevent water from entering the vessel. Hatches are essential for the safety and functionality of a ship, as they allow for access to the cargo holds, engine room, and other critical areas of the ship.
