Gravity corer

The FT510 Feritech gravity corer offers an easy to use and extremely cost effective alternative to other coring techniques.

Our latest gravity corer is robust and simple to operate in almost any water depth. The design is based on proven concepts but with innovative improvements in offering increased survey productivity. Examples of which include the quick swap barrel release and adjustable weights to control penetration.

The strong stabilising head with integral fins ensures that the corer penetrates the seabed as close to vertical as possible. The system is supplied with configurable weights allowing for 200-1000kg of additional weight, controlling penetration for a range of projects –  coastal environments to deep water locations, and everything in between.

Quick release and non-return valve

The non-return valve retains both the barrel and the sample obtained. The same non-return value is used on the piston corer and the vibrocorer and many customers now use our valve instead of the piston with comparable results.

This means operation is much simpler and safer and you still get excellent recovery. If a traditional piston is required we can offer this but with the added advantage of our hydrostatic safety release making the entire operation much safer.

Our quick release system means that barrel can be removed in a matter of minute thanks to the quick release horseshoe design used on all our systems.

Launch and recovery system

The piston corer has an optional,  over-the-side, launch and recovery system (LARS).  This greatly improves deployment and recovery efficiency, it also makes the changing of barrels much simpler and safer.

The LARS improves safety for the engineers working with the equipment ensuring the corer is securely held on deck and can be handled securely.
