In general, the construction of the deck is a form of a flat or about flat surface that covers the upper side of the rooms harshly the ship.
In terms of construction, the deck is a buildup of components that comprise horizontal construction of the deck beams (Const system. Crosswise), pembujur deck (konst.memanjang system), leverage the deck and the deck plate bounded by the belly concerning him.
The do something of the deck is to:
- Keeping kekedapan ship,
- Placing and protect the goods or cargo, the crew and passengers,
- Adding strength lengthwise and transversely.
Therefore, the requirements of the planning and installation of the deck in fact should be watertight and meet unmodified size requirements.
Wide - broad deck
In terms of architecture ship, the deck can be divided as follows:
- The main deck, the deck visceral installed as the most important component in the construction of ships that have anew one deck
- Deck second, third and as a result in the region of, which are located frozen deck deck
- Deck superstructure and deck dwelling gekadak is located above the main deck, as kimbul deck, deck lifeboat, deck teens etc.
The ships are relatively large, especially passenger ships, the deck has intensely much both under and above the main deck.
In terms of construction, known as the term deck strength. Deck strength according to the Bureau of Classification Indonesia is defined as follows.
The intensity deck of the boat which is continuous along the circumference of the basic framework of longitude.
Deck superstructure extends regarding 0.4 L amidships and a length of on summit of 0.15 L.
Deck superstructure below 12 m in length, is not considered a strength deck. The main deck can in addition to be considered a strength deck, provided it meets the requirements appreciative by the Bureau of Classification. The deck in addition to means fulfilling two functions, namely as the main deck and deck strength.
A continuous deck and located under the main deck of the ship deck called the second, third, and hence upon. This deck is called the deck in the middle of. So, didifinisi deck amid the deck which is located below the deck in permit assist to-thinking than and above the additional decks In cargo ships, which by yourself has a deck, the deck can sustain as an upper deck, deck strength, and the main deck. Planning deck more profitable., Can be viewed in terms of the gnashing your teeth-sectional ship, is convex. The advantage, the water that is in the center of the ship can flow to the side. This codicil is called camber. Camber has the size of pleasant acceptable height F of functions B, where B is the maximum width of the ship. Shown in Figure 11:28. The deck furthermore has a curved shape, as well as than viewed lengthwise ship. This curvature count lecture to and backward well ahead. Longitudinal arch is called Sheerline.
Camber and sheer usability is to bolster the flow of water out of the middle and merge less of the ship and to origin the strength of the transverse and longitudinal.
1. Construction deck transverse ivory system
As mentioned above, that the deck construction is a buildup of components that comprise horizontal construction of the deck beams, deck beam strength, leverage the deck and the deck plate bounded by the front harshly him.
a. Beam Deck (Deck Beam)
Deck beams mounted transversely at a isolate equal to the estrange of ivory, because
in checking account to the upper side of the hull beam deck - secure behind ivory tied behind
bracket. In general, the form of profiles used
is angled profile (L) or bulb dish (BP).

4. Ivory
b. Strength deck beams (Strong Beams) Beam strength deck mounted crosswise at a estrange equal to the make unapproachable a large ivory (web frames), which used the same profile impinge on following large tusks that profile T
c. Leverage deck (CDG, SDG)
Leverage center deck (deck girder center) and the fulcrum side deck (deck girder side) mounted lengthwise, right in the middle of the boat CDG (centre pedigree), even if the half-width SDG installed in the midst of the boat and the amount of SDG depends re the width of the ship (rules BKI) . Fulcrum fulcrum centre deck and side deck is the seek of the deck beams, for that defense the concern of the profile usually mengguna T profile have an effect on, but there is as well as the use of the form L
d. The deck plate
Deck plate consists of a series of sheets of plate (rows of plates) flat or in the region of flat that extends from front to urge as regards the order of and from left to right side of the hull of the ship. The sheets vis--vis the subject of the edge of the deck plates called side alley deck dish and serves as a liaison along in the middle of the construction of the deck behind the upper hull construction. Plates alleyway deck relinquish tebal.Hal relativ is due plate side alleyway is one important component in supporting longitudinal strength

4. Connection transverse deck dish
2. Deck the lengthy construction system
Construction aft deck construction system is a buildup of components consisting of a horizontal construction pembujur deck, deck pelintang, leverage the deck and the deck dish limited by the stomach following reference to him.
a. Pembujur Deck (Deck Longitudinal)
Pembujur deck mounted lengthwise concerning the deck of a ship, the estrange along along along with pembujur deck should not be on peak of ivory transverse push away. In general, the form of the profile used is angled profile (L) or bulb plate (BP).
b. Pelintang deck (deck tranverses)
Pelintang deck mounted transversely upon the deck, the push away together surrounded by the deck pelintang pelintang equal to the disaffect along after that the sides of the 3 ~ 5 ivory transverse make superior. Pelintang deck is the intend of pembujur - pembujur deck, so the have emotional impact profile in general use T profile
C. leverage deck
Leverage center deck (deck girder center) and the fulcrum side deck (deck girder side), together gone the installation rules in transverse construction system. Central fulcrum aft mounted right in the hands of the deck (center pedigree), even if the fulcrum side deck mounted together in the midst of the half width of the ship and the amount of leverage the side depending upon the size of the width of the deck upon the system construction kapal.konstruksi mixture / combination, concord of construction amassed place together once an lengthy construction
