METHOD FOR PRE-LOADING A CATAMARAN SYSTEM AND CATAMARAN SYSTEM

摘要

method for preloading a catamaran system, and, catamaran system the present invention relates to load reduction and steel savings in dead works and fillet of a catamaran system, by creating an upward lift force from a barge for dead works to shift the bending moment by flexing their own weight in dead works during transport. the present invention can reduce the span of the supports in dead works on floating catamaran barges and move the reaction forces to the inner edges of the floating barges. the upward force can cause a reduction in the tension in the elements of the dead works and fillet caused during the unloading and transportation of the dead works. the reduction of tension can make the elements withstand the additional dynamic load caused by a catamaran system without increasing the sizes of the elements suitable for an unloading operation. the reduction results in significant savings, given the size of a typical dead work for a spar hull or other offshore structure.
