Digital Templates for Hull Glazing – Shipset

Optical laser scan of finished (faired) vessel hull openings. Provide shipset of digital template drawings for manufacture of window glasses.

Dynamic Stability Investigation

The vessel was suffering sudden and uncontrollable broaches in relatively benign sea conditions. The unpredictable onset of the problem made the vessel virtually unusable. After doing basic static stability checks we surveyed the boat out of water, and determined rudder ventilation to be the main cause. Simple fences were designed and added, which cured the problem.

Preliminary structural design for dual (“stacked”) gyro-stabiliser installation. Aluminium hull vessel with steel subframe for upper stabiliser. Finite Element Analysis for fatigue life assessment.
