Hull & Deck Structural Survey

A Hull and Deck Survey is a targeted structural inspection designed to evaluate the primary physical integrity of a vessel. It isolates the core structural components from mechanical or domestic systems to provide a clear, focused assessment of the vessel’s structural integrity.

When purchasing a pre-owned vessel, the structural soundness of the hull and deck is your most critical investment factor. Structural repairs are often the most costly and technically complex issues to rectify.

This survey delivers essential clarity before you finalise your acquisition by focusing on the elements that keep the vessel safe, seaworthy, and watertight.

To deliver absolute certainty regarding structural health, the inspection integrates specialised diagnostic technologies tailored to the vessel’s specific construction material.

For Steel and Aluminium Vessels

• Plating Analysis: High-frequency ultrasonic gauges measure the precise thickness of the hull plating without damaging the paint system.
• Corrosion Detection: Scans identify subsurface wastage, pitting, and hidden internal corrosion not visible during a visual inspection.
• Weld Assessment: Evaluation of structural welds and high-stress areas to ensure material continuity and structural safety.

For GRP and Composite Vessels

• Subsurface Moisture Mapping: High-resolution thermal cameras detect temperature deltas caused by trapped water, mapping hidden core saturation in decks and hulls.
• Delamination Detection: Infrared scans reveal internal structural voids, bonding failures, and osmotic blistering before they manifest outwardly.
• Non-Destructive Testing (NDT): Combined with electronic moisture meters and percussion sounding to verify structural integrity without compromising the laminate.
