LINKS AND PARTNERSHIP	THE MARINE SURVEYOR'S JOB	THE MARINE SURVEYOR'S TOOLS	INQUIRIES

We intervene in all the maritime world i e yachting, fishing and sailing. We use a very high-tech equipment regularly checked in laboratories. This equipment is also used by the French Navy, Aéronautics, the Aerospace Industry, the French Electricity Board, etc...

For the hull and the deck

ultrasonics analysis in oder to define :
- the thickness of the materials.
- the homogeneity and the thickness of the polyester fiber glass so as to reveal the possible delaminations or faults (osmosis).
- the thickness of paint or gel coat.
- the thickness of plating steel sheets to reveal any corrosion or electrolysis phenomenons.

For the keel, the rudder blade and the.
center board

- checking of the breaking of the keel bolts (without dismanthing them).
- checking of the corrosion of the keel (steel, aluminium)

For the masts
and the rigging

- checking by chemical application and ultrasonics.
- detection of mini fails.
- checking of the thickness of anodisation and paint.
- checking of the level of corrosion.

For the engines

- search for internal corrosions.
- oil analysis.

Others

any examination by ultrasonics :
- corrosions of the hulks, the barges, the landing stage pillars, the piping, the tanks, etc...
- the osmosis level of the polyester fibre glass.
- the wear of the coating (gel coat, epoxy)
- checking of the thicknesses (antifouling, coating)

Mobile equipment used

- numerical ultrasonics device : Epoch III
- detector of the omosis in of the fibre glass : Sovereign.
- measure of the thicknesses :Elcometer
- regulator of the hardness of the material : Durometre Barcol et Rockwell
- Sound level indicator...Noise meter 30 to 130 DB
- Computer interfaces.
