Naval Applications of Spar Technology in a Seabasing Environment

Abstract

Spar technology was initially explored in a 2003 CISD study for the application of a Deep Water Stable Craneship. This vessel used the enhanced seakeeping properties of a spar to dramatically increase operability in a seaway. Whilst the spar concepts developed to date have offered a range of particularly strong, and sometimes unique, capabilities the design has required an undesirably long spar, restricting use to deeper waters. The first part of this study shows the practicality of reduction of the spar length by changes to spar geometry, reduction of platform mass, and reductions in freeboard. The study then explores a range of potential applications for spar technology and in a particular three concept designs are detailed; a helo 'lily pad', boat support platform and weapons platforms.
