Shipek grab
This grab system is designed to recover small sea bed surface samples of up to 2 Kg. The system can operate in water depths of 300 m. The grab operates by means of a hand priming system that is set on the surface. The grab is then lowered to the sea bed where, upon contact, a trigger weight on the grab strikes a release mechanism and the sample compartment closes to encapsulate a sample of sea-bed sediment.

An electro-hydraulic winch complete with metering system, is used to lower the grab to the sea bed on a 6mm wire at a speed of 60/70 m/minute. This allows you to record the depth of sample.

This system is ideal for taking a large number of small volume samples and is often used to take sediment samples in conjunction with other equipment on the same project.
