Marine Applications

Marine applications have included, lifeboats and other fast surface craft, luxury yachts, high performance racing yachts, naval vessels and submarines.

Application Example

Rambler 88 keel monitoring

Rambler 88

The keel is probably the most critical structure on a modern race boat as a failure can mean instant capsize and an acute risk for crew safely. Epsilon Optics has supplied a fibre-optic strain sensing system to Rambler 88 to enable continuous strain monitoring of the canting keel. This generates a complete load history which, supplemented with regular NDT inspection, helps ensure the continued integrity of this critical and highly stressed component.


Application Example

Oracle Racing LogoEpsilon Optics provided all the fibre-optic strain sensing for Oracle Racing during their last two successful America’s Cup campaigns. Virtually all critical structures were monitored including hulls, foils and rig, providing vital feedback for the designers and reassurance for the sailing team. This involved working very closely with the design and build teams in order to meet the tight deadlines and rapidly changing requirements.

Epsilon Optics sensing systems have now been applied to a wide range of high performance race boats and luxury yachts world-wide. Our sensor interrogation units are very well suited to this type of application where high performance and reliability are absolute requirements in very demanding environmental conditions.

Epsilon Optics has developed a range of sensors and installation methods suitable for virtually all key structures including hull, mast, keel, movable foils and standing rigging. These range from surface bonding of composite patches, to direct embedment of the sensors in the laminate during lay-up. For the majority of structures, sensor installation can be carried out quickly and simply with minimum impact on the build program.

Key Benefits Heading

High performance yachts and race boats

  • Verification of design loads (particularly dynamic loads which can be difficult to predict)
  • Performance enhancement, both during competition and during set-up and tuning
  • Long term structural health monitoring
    Mitigating the risk of overload and structural failure during competition

Fast surface craft

  • Monitoring of slamming loads (Our AE-3030 high-speed acquisition system is particularly well suited for this)

Large surface vessels

  • Monitoring of hull stresses due to sea conditions and cargo distribution. (typically using long gauge length sensors)
  • Suitable for ships carrying hazardous cargos such as oil and LNG (fibre optic sensors are intrinsically safe)
