Construction hull transverse construction system.
Hull construction is share of the skeletal system is eseluruhan kkapal construction as the side wall of the vessel put it on:
- Withstand the compressive force of the sea water side
- Together the base and the deck is a longitudinal strength of the vessel
- Local load bearing, between others, the load going re for the launch, collisions subsequent to ships or adjunct objects
As the successor to the forces usual channeled kekonstruksi deck pads, especially in the construction of the transverse frame
Therefore hull plate reinforced when vertical stiffener stiffener-called tusks.
Joist is named / called according to location.
- Middle share of the ship numb the main deck called the main ivory
- Niche areas (recess recess stern and bow) called tusks recess
- Ivory tusks and loud tusks In the hull mounted at any remove from ivory, but at a colossal surgically remove from (3 ~ 5 distance ivory) mounted large ivory.
Rules in accordance gone the installation of large ivory pedestal mounting wrang full concerning double pedestal.
The make standoffish along together surrounded by the ivory is one of the most important factors in determining the sizes of ship construction.
Distance ivory adequate (ao) of the aft bulkhead niche to 0.2 L of the tip of the bow of the boat is calculated by the formula: ao = L / 500 + 0.48 (m) ao max = 1 m
In the niche place stern and bow recess ivory distance condensed, that should not be on top of 600 mm, because the bay areas bow withstand large all-powerful quantity of splashing (answer). While the stern niche withstand vibration and rotation engine propeller shaft (propeller).
At the summit of the joist beams connected in the melody of the deck, though the lower share is amalgamated as soon as the base plate and to tie unwavering the knee dish (bracket).

Senta side (side stringers)
Sentra side mounted lengthwise on the order of the hull, even if the number of Senta installation depends re the size of the high ships.
- If the summit of the double pedestal kesisi deck less than 4.5 m are not required to install Senta side.
- If the size of the high-mounted 1 m 6 Senta side
- If the size is 9m high mounted 2 Senta side
Hull construction in system construction lengthwise.
In this system the main joist is not installed vertically, but mounted horisontalmemanjang / lengthwise concerning the side of the ship to the estrange in the midst of 500mm-1000mm, this joist (going in this area speaking for the side) called pembujur side (longitudinal side). Pembujur this side of the edges are supported by transverse watertight bulkhead and watertight bulkhead surrounded by the two walls, pembujur-pembujur side joist are supported by a large irate called pelintang each side is surrounded by 3 ~ 5 ivory transverse set against.
In tankers which have double walls upon both sides (double hull / double skin), sometimes pelintang side not use the T profile, but using a plate.
Pembujur-pembujur side for ever and a day / penetrate pelintang side and welded upon rushed- but pelintang side. While the transverse watertight bulkhead pembujur-pembujur side scrape and tied / welded to the bracket. The estrange along in the middle of pembujur hand held together along with pliers melin- ivory estrange, where the remove from should not be greater than 1000 mm

As considering the transverse construction system, Senta side (side stringers) can in addition to -pasang the outstretched hull construction system, and installation rules Senta this side is equal to the transverse construction system.
