SpiralWeld™ assembled and overlaid helicopter tie down arrangements have been deployed in navy fast strike vessels around the world.
Working with Vosper Thornicroft design engineers SpiralWeld™ developed procedures to allow the cast super-alloy helicopter tie-downs to be installed into the ship deck plates, which were tyically of lower grade steel. The arrangments were finihsed withe a machined prep to allow easy weld instalation to the deck with extremely high structural integrity.
Three hundred of these mission critical components were produced over a period of 2 years and installed into a number of naval fast strike vessels.
These high integrity, differential material welds were qualified to an international standard to meet with the vessel classification requirements. A number of designs were produced with different overlays to achieve various deck installation methods.
