Why our Low-Pressure Overshot?

The Aquaterra Energy Low-Pressure Overshot has been designed to support low-pressure riser top hole drilling activities. The Overshot provides a safe and effective method of fluid and pressure containment on any API cut casing or conductor profile and a means of connection to the drilling unit’s diverter system or riser. The overshot can be deployed both at the surface or subsea, having a manual drive bolt or alternative hydraulic seal activation.
