Our Vibro-Corer is ideal for the exploration of near-surface grounds (i. a. for the subsoil investigation of offshore cable routes). The Geo-Corer 3000 + 6000 is a high frequency, electrically driven vibrocoring system. It can penetrate fast into all common unconsolidated sediments, including compact sands and stiff clays. The modular construction of the Geo-Corer enables a core recovery with a length of 3 m, 6 m or 9 m. The Vibro-Corer can be deployed from a relatively small vessel, based on its modular system and lightweight structure.

Deep Sea CPT

Deep Sea CPT is performed with our high-resolution Cone-Penetration System. The Cone-Penetration Tester with pore pressure measurement (CPTu) is ideal for the near-surface exploration of e.g. offshore cable routes. Our system is equally suited on- and offshore for ground reconnaissance by means of CPTu. The Cone-Petration System operates from the seafloor during offshore operations. The tool is lifted just a few meters and stays in the water during continuous offshore surveys. The device reaches with the so-called “Dangling Operation” optimal performance times. The application of the Cone-Penetrtion System is possible within a very short time from almost every platform (truck, jack-up platform, pontoon, vessel) because of its compact construction. The powerful hydraulic drive enables a CPT-penetration depth of up to 30 m. Therefore, it is suited for a variety of exploration.

Dynamic load testing

The realization of measurements, accompanying the installation at the pile, requires an accurate implementation. An early observance throughout the planning saves costs and unpleasant surprises during the construction process. The “ GmbH” offers installation predictions for foundation elements, such as bulkheads or offshore-posts, to support your project.

We perform dynamic measurements at foundation piles as well. The measurements are executed for example as dynamic load testing. Force and deformation on the pile head is measured collateral to the dynamic probing. A measurement for a ramming impact, e. g. on-situ concrete piles, is possible too.

Pile carrying capacity can be arranged from the gained data. The deduction of an increasing factor for the pile carrying capacity is possible depending on the arrangement of the pile-tests. Our clients profit especially from our know-how, which is built on several research papers and project tasks in this field, particularly in the offshore wind sector. During the installation of dynamic probing measurements, a monitoring of the permissible voltage in the pile, according to DIN EN 12699, is possible as well.

The dynamic measurements can be realized on displacements piles, in-situ concrete, injection piles, micro piles, wooden piles, steel profiles or bulkheads. A PAX Pile Driving Analyzer from the “PDI inc.” company is used as an acquisition unit.
