The most important engineering feat on an U. Naval vessel is its watertight doors. Watertight doors do not move the ship through the water, nor do they act as any sort of weapon and they really do not contribute much to the ships main mission in general, but they can be a very valuable asset when they are needed to be used for what they do. The water tight doors protect the ship and its personnel from sinking and drowning in the case of a flooding casualty, by sectioning of the ship to contain the casualty. Watertight doors seem like a nuisance in everyday life on the ship when you have to bend over and crawl through them time after time, but if a ship were to ever to encounter a situation in which there was flooding you would not consider them to be a nuisance. .
Watertight doors are designed to section off compartments of a ship so that if there is flooding in one section it does not spread to the rest of the ship thus isolating the casualty. Isolation of the casualty will allow for the crew to hopefully continue to keep the ship afloat and continue with their mission. Isolation allows for the ship to stay afloat, in that only part of the ship with fill with water and hopefully only one section, allowing the crew to escape from that section. Isolation also allows for the ships personnel to detect where exactly the casualty is and then can make a decision as to what they are going to do to combat it. Depending upon the sever ness of the casualty in the sectioned off compartment, which may be determined by looking through the peephole that is built onto the water tight doors, the ships crew may be able to enter the section in which the casualty is and stop or slow the flooding. Once the crew has gotten out of harms way they will be able to adjust the ballast of the ship in order to make up for the extra weight from the addition of the water. If the water tight door works correctly the ship will still be able to stay afloat and somewhat righted depending on how much water was brought on.
There were sixteen watertight compartments connected by electric doors on the Titanic. ... The watertight emergency doors were ordered to be shut (Foster 63-64). Water filled the first five watertight compartments, and the damage slowly crept into the sixth (Lord 70). Several boiler room workers were trapped in watertight compartment number five (Foster 66). ...
Though 85 percent of the Avalanche's components are shared with the Suburban, only the door handles and side mirrors are the same on the outside. ... This Avalanche also heralds the exclusive debut of North Face's Water Duffalo bags, which are claimed to be completely airtight and watertight. ...
A white cement that connected the stones and made them watertight is still intact and stronger than the blocks that it joins (Zulac). ... Not very many cultures can build pyramids and temples with mortar, and a glue that is watertight and lasts thousands of years. ...
The locks worked with massive sets of doors placed widely enough apart to well accommodate the longest ships of the time. When a ship enters the lock, both sets of doors are closed, entombing the ship in a watertight compartment. The chamber is then filled until level with the upstream water, when the front doors are opened, allowing the ship to pass. ...
On the morning of April 11, 1912, Thomas Andrews (Appendix A: Portraits), a ship builder, and the nine-member "guarantee group- from Harland & Wolff's yards, held a full dress drill of the watertight safety doors. ...
The choice of life: Does a person have the right to decide between life and death? Should a patient be allowed to take the easy way out and get help from a doctor to commit suicide, or die according to their destiny? There is a major clash of opinions between the people who think that assisted suici...
Using an ingenious system of sixteen watertight compartments in her hull and more lifeboats than the current law required. ... Many had tried to go to the boat deck but had found it blocked by closed doors or crewmen who refused to allow them to enter the first-class or second-class areas. ...
