There are many classification methods for windows on ships according to their setting position, form, structure, material and function.
There are fixed and movable portholes. The former cannot be opened, and the latter can be opened. According to the watertight pressure capacity, they are divided into heavy-duty type below 20Pa, ordinary type 50-100Pa, and light type (below 20Pa). Heavy-duty movable porthole stone windows in watertight areas are equipped with anti-riot covers, so that such windows cannot keep daylight in stormy weather. The porthole is round, and the specifications are indicated by the diameter of the transparent glass. Usually there are ø200mm, ø250mm, ø300mm, ø350mm, ø400mm, depending on the size of the ship (rib distance). Those who also serve as escape ports must be above ø350mm.
Rectangular windows are used in superstructures without watertight requirements. The pressure is less than 50Pa, and the larger the light transmission size (width hm × height bw), the lower the pressure.
The deck daylighting window is installed flush with the deck plane, and the translucent surface is made of prismatic glass, so that the space under the deck does not receive direct sunlight, but uniform and soft scattered light, which is usually used for top daylighting of public cabins and passages.
The skylight window cover can be opened and covered with round or rectangular translucent glass. In addition to daylighting, it also serves as natural ventilation. It is generally installed on the top of the engine room, stove compartment, kitchen or small cabin.
Generally, the crew cabin has one window, and the senior crew’s living room has two windows. There are 2 to 4 windows in public cabins, such as restaurants and smoking rooms, where the outer sidewall is viewed. If the structural reinforcement is not restricted, the cabins below the boundary line should be provided with daylighting portholes, but the number should be minimized.
Portholes, boats generally use ø300mm, the minimum is ø250mm, and large and medium-sized ones usually use ø350mm or more. For square windows, suitable windows are also matched according to the rib spacing, and watertight pressure requirements are also considered. The light transmission size 300mm×400mm can bear 50Pa pressure, 350mm×50mm, 400mm×550mm, 450mm×600mm can bear 20Pa pressure. In the general cabin windows in the superstructure, large-size (550mm×600mm, 600mm×700mm, 800mm×900mm) windows are used for cabs that require a wide field of vision.
The window layout should be conducive to reasonable and even lighting in the room. If the two adjacent walls of the cabin are both outer walls, the windows are opened on both walls at the same time, and they deviate from the angle of the two walls, which is conducive to the uniform distribution of the entire indoor illuminance. In fact, opening windows relative to the two walls can make the light distribution more ideal. However, in addition to the halls or cabins, the general empty cabins or living rooms are less likely to be set up in this way, and the rooms that can be opened on both adjacent walls are not. many. When the windows can only be arranged on one side, one window is best in the middle of the room length. The two windows should be properly opened so that there is a certain amount of light on both sides.
The influence of the setting of doors and windows on the ship’s appearance should be reviewed. The size, height, and form of the windows on each deck should be as uniform as possible, and the height of the windows should be parallel to the arc, so that the spacing of the windows has a sense of rhythm.
The height of the eyes when a person stands is 1300~1700mm. Generally, the height of the center line of the cabin window can be set at 1500mm or 1650mm, except for those who are required to be able to watch the outside scenery while sitting on the cruise ship.
