Abstract

Un corps étanche est proposé pour utilisation dans des opérations de forage telles que des opérations de forage de puits de pétrole et de gaz. Le corps étanche comprend une coque qui définit une cavité fermée; la coque est constituée d'un alliage métallique. Le corps étanche possède une flottabilité neutre ou positive. Dans un mode de réalisation, le corps étanche comprend en outre une structure de renforcement dans la cavité. La structure de renforcement peut comprend une ou plusieurs paires de nervures contiguës à une surface intérieure de la coque du corps étanche.
