Summary

Description
Français :

Le pénétromètre Penfeld est un appareil de sondage géotechnique. Posé sur le fond, il effectue des mesures à l'aide d'une pointe instrumentée (piézocône) dans le sédiment.

Le pénétromètre est conçu pour travailler jusqu'à une profondeur d'eau maximale de 6 000 mètres.
Il est doté d'une tige poussée dans le sédiment à 2 cm par seconde, jusqu'à une profondeur de 50 mètres.

La tige de 36 mm de diamètre est enroulée sur un tambour de 2,20 mètres de diamètre et redressée plastiquement lors de la pénétration suivant la technique du « coiled tubing ».

Sur ces images, l'instrument est réglé avant d'être mis à l'eau dans le bassin d'essais.

The Penfeld penetrometer is a geotechnical survey device. Placed on the bottom, it takes measurements using an instrumented tip (piezocone) in the sediment.
The penetrometer is designed to work up to a maximum water depth of 6,000 meters.
It is equipped with a rod pushed into the sediment at 2 cm per second, up to a depth of 50 meters.
The 36 mm diameter rod is wound onto a 2.20 meter diameter drum and plastically straightened during penetration using the “coiled tubing” technique.

In these images, the instrument is adjusted before being put into the water in the test basin.
