How are watertight doors classified?
doors, except doors between cargo spaces, are classed as follows: (1) Class 1—Hinged. Class 2—Sliding door, operated by hand gear only. (3) Class 3—Sliding door, operated by power and by hand gear. (b) The following.
What are watertight compartments on a ship?
Watertight bulkheads are vertically designed watertight divisions/walls within the ship’s structure to avoid ingress of water in the compartment if the adjacent compartment is flooded due to damage in ship’s hull.
What makes watertight doors watertight?
A watertight ship door or hatch withstands a so-called ‘water column’ (water pressure) from both sides. The closure between two compartments below the waterline will typically be watertight. It is essential that these compartments are resistant against great water pressure, as is the case during a major water leakage.
What are watertight doors made of?
The watertight ship door is designed mainly for mounting in walls of ship’s superstructures. The door can be made of steel, aluminum or stainless steel. Pins of closures are settled in bronze sleeves.
What is the difference between watertight and weathertight?
In practical terms, the difference between weathertight and watertight is that a weatertight fitting shall withstand water pressure from the outside (be watertight from outside), whilst a watertight fitting shall withstand water pressure from both sides.
What is a common place for leakage at watertight closures?
Where is a common place for leakage on doors or hatches? Around dog spindles where the spindles pass through door frames.
How many watertight compartments did the Titanic have?
16 watertight compartments
The Titanic had 16 watertight compartments, and the ship could stay afloat with up to four of these compartments flooded. After hitting the iceberg, water began flooding the Titanic’s forward six compartments.
What are the 3 types of bulkhead?
The three basic types of bulkheads found on most ships, are: i. watertight, ii. non-watertight and iii. oiltight or tank bulkheads.

What is GT and NT?
Gross tonnage (GT) is a function of the volume of all of a ship’s enclosed spaces (from keel to funnel) measured to the outside of the hull framing. Net tonnage (NT) is based on a calculation of the volume of all cargo spaces of the ship.
