Nautical Structures
Nautical Structures was contracted to design, engineer and build a series of very custom cranes for a recent 98-meter build in Germany. The most challenging of the cranes were two sets of two 4500-Kg / 10,000-Lb capacity overhead beam cranes providing a total hoisting capacity of 9000-Kgs / 20,000-Lbs per side. Due to the unique and spectacular naval architecture of this build, these large-capacity cranes are installed in the overhead of the vessel's full-beam beach club, below the main deck. To enhance the utility of the beach club space, the large shell-doors are designed to fold-down to open, and are treated with the same teak surfaces as the primary sole in the Beach Club. Once open the tenders may be removed from this space and a very large and opulent lounging and entertainment area is made available to owner and guests. This naval architecture added significantly to the complexities of the cranes. Because the shell-doors open down instead of up, the tender has to be transported a total of 7.6-meters to pass over and clear the door when launching. The cranes stow in a space only 4.3-meters long and telescope outboard in three sections. Built entirely from stainless steel plate these massive crane structures weigh 8-tonnes each! These cranes are synchronized together to ensure that when launching the tender the two crane systems move together.
