OSIL's 3m Gravity Corer is a simple and reliable instrument for collecting sediment cores from coastal and deepwater sites for sample analysis. The corer uses the pull of gravity to penetrate the seabed with its carbon steel core barrel, which can collect ... Moresamples of up to 3m in length.

The 3m Gravity Corer is easy to use and very cost-effective. The entire corer is made from carbon steel and is fitted with stabilising fins to ensure that the corer penetrates the seabed in a straight line. The standard lead weights supplied with the corer comprise of 4 layers, each weighing 62kg. Each layer comes in two segments and the total added weight is 248kg.

A replaceable core liner is housed within the carbon steel barrel to ensure that it is simple to remove the collected sample. The barrel is fitted with a sharpened replaceable carbon steel core cutter to ensure minimal disturbance. Sample loss on retrieval is minimised by a core catcher fitted inside the end of the barrel.

The robust design of OSIL's 3m Gravity Corer can be easily customised for a wide variety of applications. The corer's simplistic design means it calls for little maintenance and can be galvanised or painted to the customers requirements.
OSIL's 6m Gravity Corer is a simple and reliable instrument for collecting sediment cores from coastal and deepwater sites for sample analysis. The corer uses the pull of gravity to penetrate the seabed with its carbon steel core barrel, which can collect ... Moresamples of up to 6m in length.

Feritech's 2m Electric Vibrocorer features the most advanced technology available. Designed to withstand the harsh offshore environment, it combines exceptionally robust build quality with state-of-the-art real-time data sensors. The system is modular ... Moreand can be configured to collect up to 12m long cores, offering class-leading performance with ultimate system dependability. Our vibrocorer systems are available for purchase or to rent.
The SEAS DC-01S Gravity/Drop Corer is designed to recover high quality core samples up to 3m in length from a variety of soft sediments. Like all SEAS equipment, the DC-01S Gravity/Drop Corer is manufactured from quality materials. With a range of core ... Morebarrel options available, the DC-01S Gravity/Drop Corer can be configured for whatever your sampling program objectives are - environmental, contamination studies, anchor surveys, mineral exploration, sedimentology, etc.

The DC-01S Gravity/Drop Corer can also be deployed with the SEAS PC-24L Long Piston Corer to acquire undisturbed surface samples that are often missed from long piston core samples.
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.... More

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 OSIL Box Corer is a simple and reliable corer for sampling an area of 0.1 m2 of sediment with minimal disturbance and sample contamination. Its unique double shovel design allows easy access to the sediment for subsampling for subsequent scientific ... Moreinvestigation. OSIL Box Corers are widely used for sampling in biological, chemical and geochemical, applications as the relatively large block of sediment provides a large well preserved sample.

The OSIL Box Corer is easily deployed from a deck stand and lowered on a standard lifeboat no-load release, which activates after sediment penetration. The box is closed, top and bottom, by two closely-fitting shovels, mounted on pivot arms. Removable weights allow the corer to be used successfully in a range of sediment types.
The OSIL Mini Box Corer is a simple and reliable corer for sampling an area of 0.05m2 of sediment with minimal disturbance and sample contamination. Its unique double shovel design allows easy access to the sediment for subsampling for subsequent scientific ... Moreinvestigation.
