Framing System

It is the various methods used to stiffen the bottom shel and side, plating of a ship against the compressive forces of the sea.


  1. Transverse Framing System.
  2. Longitudinal Framing System.
  3. Combined Framing System.
1. Transverse Framing System:

  • A framing system which is often adopted for the ships experiencing severe racking stress and having dominance over sagging and hogging stress.
  • Deck beams are used to support deck and beams are supported by deck girders, knees are used to connect beam to ship side framing.
  • Transverse frames at 3 m interval used to support the ship side plating through the length of the ship.
  • Floor plates at 3 m intervals with center and side girders used to stiffen the double bottom space. 
2. Longitudinal Framing System : 

  • A framing system which is often adopted for tankers and must be used for vessels greater than 198 metres in length.
  • Longitudinal stiffeners are used along the ships sides and throughout the tanks length.
  • Side and bottom transverses are used to support the longitudinals against compressive loading.
  • Longitudinal bulkheads are provided to divide the cargo tank into center tank and wing tanks.
  • Griders are used to support deck and bottom plating.
3. Combined Framing System :

  • A framing system with best compromise to suite the INSITU structural demand to counter act the composite stress and strain.
  • Decks are supported by deck transverse with deck longitudinals interconnected the deck girders are used to support deck transverse.
  • Transverse frames along with side longitudinals used to support the ship side plating.
  • Floor plates with longitudinals and girders are used to strengthen the double bottle space. Brackets and knees are used to connecting members.


  1. Are all warships use the combined approach? Or only certain warships?

  2. Since it has such an effect, proficient framing ought to be considered for any of your craft.
