UK-based Ocean Scientific International Ltd (OSIL) has added a new hydraulic vibrocorer to their existing range of products.

The hydraulic system can be used as a standalone sediment corer, or can be adapted to allow integration with subsea vehicles.

The use of hydraulics opens the system up for use in very deep water in conjunction with a seabed hydraulic power pack.

According to OSIL, a range of systems are available depending on the specific application, offering from 2500kg to over 7000Kg centrifugal force, and each providing a well-structured core sample that retains the individual layers.

The hydraulic model is based around the existing modular electrical vibrocorer, which allows for a 3m, 6m, or 9m system to be constructed depending on requirements. This can be assembled dockside, or on the vessel itself, before deploying over the stern.
