Portsmouth based composites specialists Magma Structures, have delivered three of the world’s tallest carbon composite free-standing masts. The rigs are designed to withstand bending loads of more than 40Mn; more than twice the load on a Boeing Dreamliner wing. The masts were ordered by a German shipyard and are destined for a sailing superyacht.
Built at Magma Structures’ waterside manufacturing facility near Portsmouth, the masts have taken over 3 years to develop, test, design and build using advanced composite manufacturing processes. Over 70 people have worked on the build of the rigs, including an in-house team of specialist composite design engineers.
The rig concept was designed by Dykstra Naval Architects in the Netherlands; the load analysis and engineering drawings were compiled by Magma Structures’ in-house engineering design team. Each mast is able to rotate using systems mounted on ‘wings’ at the side of each of mast; adding to both the design complexity and build challenge.
