The Piston Corers operate in a very similar manner to traditional gravity coring systems, with the exception of the piston itself, which acts as a plug on the coring barrel array once the corer has been fully deployed into the sediment that, together with the core catcher, holds the sample more securely inside the core liner than in a regular gravity corer system and prevents sediment slump. The piston also reduces internal friction within the core liner and prevents clumping of the sample. This ensures that the OSIL Piston Corer systems deliver a more well-defined sediment sample to the operator.
Piston Corers are one of the most important basic tools used in the study of marine sediments, and OSIL offers customisable systems (including Launch and Recovery Systems and Winches) from 4m to 60m in length. Recent shipments have been destined for West Africa, Korea, Spain, South America and the Philippines
OSIL are experts in the manufacture, global supply and operation of sediment corers up to full ocean depth, with particular experience in the oil and gas and marine mining industries and a worldwide customer base that covers a wide range of sectors including offshore renewable energy, coastal engineering, ports and harbours, oil and gas, aquaculture, water and utilities, academia, research and statutory monitoring.
