Une nouvelle technique pour les mesures de precision sous-marines (metrologie) est en train de devenir un standard dans l'industrie petroliere: la metrologie inertielle.
Cette technique est basee sur les mesures inertielles de haute precision en topographie inertielle terrestre que j'ai mis au point depuis 1996 (il s'agit simplement du relever repetitif en 3D d'un point inconnu a partir d'un point connu).
J'ai forme et entraine plusieurs compagnies a ces techniques pour l'offshore depuis 4 ou 5 ans.
Je peux developper ces capacites dans votre compagnie.

* la metrologie inertielle "pure" (sans autres senseurs comme DVL ou LBL) fut testee en 1976 par Alain Stankoff et presentee a l' OTC a Houston en 1977.

Contact me if you are interested in developing INERTIAL positioning capabilities, including inertial land survey or subsea metrology, because you need positions and orientations in a more efficient and accurate way.
Inertial navigation will deliver high precision position and orientation in any environment (land,
underground or off-
shore, particularly
subsea).
This inertial technique is now requested more and more frequently by Oil and Gas companies for subsea metrology for example because:
> it is faster than acoustic or mixed methods (~3h)
> the method is not patented or proprietary, neither is the hardware
> it doesn't require line of sight or visibility (U jumpers, platform legs, obstacles, sediments)
> it is not affected by the acoustic environment (drilling, simops, product flow)
> you can complete the metrology while drilling is being done nearby. You can actually do the metrology using the drilling rig ROV.
> in the ARCTIC environment it doesn't affect marine life (no acoustic signature)
Since 1996, Inertial Land Survey has been successfully used under canopy instead of GPS or theodolites, in particular in the land seismic business (For Oil and Gas exploration). While it is now common in North and South America, it would be beneficial to any survey operation in Jungle or Forested area of the world (Asia, Africa, Australia).
