20100186650PRELOADING TO REDUCE LOADS AND SAVE STEEL ON TOPSIDES AND GRILLAGE OF CATAMARAN SYSTEMS - The present invention reduces loads and saves steel on topsides and grillage of a catamaran system by creating a counteracting moment to offset a sagging bending moment of its self-weight on the topsides during transportation. The present invention can reduce the span of the supports on the topsides on the catamaran float-over barges and move the reaction forces toward inner edges of the float-over barges. The counteracting moment can cause a reduction of stress on the topsides' and grillage's members caused during the topside offloading and transportation. The stress reduction can result in the members withstanding the additional dynamic load caused by a catamaran system without increasing member sizes adequate for an offloading operation. The reduction results in a significant savings, given the size of a typical topsides for a Spar hull.07-29-2010

The frame member can be concurrently engageable with the posts to fix the pontoon halves together in the operating configuration. The posts can be interconnected with one another when the first pontoon half and the second pontoon half are in the stowed configuration.02-11-2016
20160052602MODULAR PONTOON BOAT - According to embodiments disclosed herein, there is provided a modular boat that includes a first pontoon, a second pontoon, an arched coupling member, a deck frame, a deck surface and at least one inflatable seat. The first pontoon has a first longitudinal axis and the second pontoon has a second longitudinal axis. The arched coupling member is removably coupleable to the first pontoon and the second pontoon so that the arched coupling member is perpendicular to the first and second longitudinal axis. The deck frame is removably coupleable to the arched coupling member. The deck surface is removably coupleable to the deck frame and extends in a first plane that is parallel to a second plane that contains the first and second longitudinal axis. The inflatable seat is removably coupleable to the deck surface.02-25-2016
