Piston Coring System

The SEAS Piston Coring System is a robust multipurpose coring tool that can be configured for
Piston Coring or gravity / drop coring in water
depths to 7000m and core samples up to 24m in
length.
The SEAS Piston Coring System can be easily
mobilized by road or sea freight and can be
configured on-site for different coring conditions.
The weight package can include up to ten 250kg
weights to cater for varying seafloor conditions
and core lengths. The core barrels include reuseable outer steel barrels and matching PVC or
polycarbonate core liners to facilitate easy
handling of core samples. For short cores, a
single-use 3m aluminium barrel can also be used.
In addition to the main core a 1.5m gravity corer
can also be attached to the trigger weight. This
can provide a good sample of the uppermost
sediments which are often disturbed in long
piston or gravity cores.
