MARINE APPLICATIONS
Ultra High Tensile Steel Applications are Available for the Marine Industry.
Weight Saving Will Be The Keyword From Now On.
CISI is your specialist for solving the weight problems in the Marine Industry by introducing HT-steel applications.
Some examples of weight saving in our program are:
- Helidecks made out of HT-Steel:

This results in the same weight figures as existing aluminum helidecks.
Compared to helidecks designed with mild steel a weight reduction of approx. 40 Tons can be expected when using our unique HT-steel concept.
- Living Quarters made out of HT-Steel will give a weight reduction up to 25% on standard unit weight.
- Drill Floor to plating at impact sensitive areas replaced by our HT-Steel design will reduce approx. 40% of weight.
- Spreader Beams re-designed into HT-Steel results in average weight reduction of 35%.
- Crane Booms / Hoisting Structures and other high loaded non-buckling sensitive crane structures.
- Main Supporting Frame for ROV's proves to withstand clashes and the harsh ocean environment.
approx. 3x longer as conventional aluminum frames
- Pressure Vessels. Significant weight reduction can be expected because wall thickness of subject vessels is linear related to the yield strength.
- Winches (including drums)
- Risers
- Many Other Applications
Note: Quoted percentages are a rough estimate of weight reduction compared to standard steel structures.
