Shipek grab

The FT530 shipek grab is designed to sample all types of unconsolidated sediments, from soft ooze to small pebbles, which can be collected from near offshore and deep lakes.

The robust centre-pivot sampler can recover virtually undisturbed and unwashed to the surface from any depth.

The main use for the shipek grab is for sampling benthic organisms living at or immediately below the water and for sediment containing a major populace of non-sessile forms.

Feritech Shipek grab sampler

How does a Shipek grab sampler work?

 

As the Shipek grab comes into contact with the sea floor the trigger weight releases the  helical springs causing the sediment bucket to rotate by 180° scooping up the sediment sample. Once the bucket has rotated it  remains closed by the residual torque of the same helical springs thereby protecting the sediment sample.

The rotation of the bucket is quick and penetrates the sediment cleanly, particularly if sampling  clays, muds, silts or sands. Once closed the sample is completely enclosed therefore preventing washout during retrieval to the surface. Samples can be retrieved even if obstructions prevent the bucket from closing properly. Once recovered to deck, the bucket is simply removed by operating two retaining knobs. The sample is then processed as required.
