The SEAS Piston Coring System can be easily mobilised 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 Piston Corer, a 1.5m Gravity/Drop 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.
The Geo-Piston Corer, including the unique launch and recovery system (LARS), has a modular design and is available in four standard lengths of 6 m, 12 m, 18 m and 24 m, but can be customised for your specific project anywhere from 3 m to 30 m lengths. ... More

All systems components fit into a standard 20 ft container that can be used for transportation, storage and for operations offshore. All the carbon steel parts are hot-dip galvanised to protect against corrosion.

The system features a standard storage rack, a comprehensive selection of spares, and a complete set of tools for efficient and safe operation.
High Frequency Vibration The Geo-Corer 6000 Vibrocorer is a high frequency (28 Hz), electrically-driven vibrocoring system. It can penetrate fast (thereby enhancing the quality of the core) into all common unconsolidated sediments, including compact ... Moresands and stiff clays, and structureless chalk.

Deep Water Operation
The Geo-Corer, new models built after 2010, is rated to a maximum water depth of 300 m. It can be upgraded to the pressure-compensated version for operation in water depths down to 600 m and more.

Variable Coring Parameters
The two standard configurations are designed to take high quality cores of 3 m or 6 m length, in ordinary PVC liners with an internal diameter of 106mm. The penetration force can be adjusted by varying the deadweights on the vibrator head.

Lightweight Structure & Small Vessel Operation
This modular vibrocorer system can be assembled manually in less than 2 hours (a crane is required to bring it upright) and can be deployed from a relatively small vessel. Given its lightweight construction and smart pull-out system, it requires a limited hoisting power of maximum 5 tonne. Its low overall weight minimises transportation costs.

Pivoting Core Barrel Head
The pivoting corer head allows rapid change-out of the core barrel and easy retrieval of the core liner, while the vibrocorer remains in the upright position.
OSIL's 6m High Power Vibrocorer has been designed as an easy to use, easy to transport modular vibrocoring system capable of collecting samples up to 6m length in 600m water depth.

The CAT has been designed for use as an underwater instrument location and positioning aid. They have applications as part of the recovery system on oceanographic moorings and platforms. The precision, high output power and commandable transponder feature make these instruments ideal for use with positioning systems in difficult acoustic environments.

The CAT utilises EdgeTech's field proven Binary Acoustic Command System (BACS) code structure. The BACS coding structure provides 12,000 possible secure command codes. Each transponder is factory programmed with its own unique command set which includes transponder ENABLE, DISABLE. Whenever the instrument receives a command it responds with a status reply message which indicates the orientation of the instrument (tilted or not tilted).

The transponder function can be turned on or off with the ENABLE and DISABLE commands. When disabled the transponder will not reply when interrogated. This ensures that the unit will not interfere with nearby instruments and that no battery energy is wasted replying to interrogate signals meant for other systems
