Exploration Offshore / Onshore

Hydrographic survey

Survey of water bodies (bathymetry)
Scour monitoring
Surface exploration

Survey of water bodies (bathymetry)

Various hydrographic sounding methods are suitable for bathymetric surveying of river bottoms. For example, vertical sounders (singlebeam echosounders) are used to map the morphology of river bottoms along profiles. This serves e.g. for the survey of dredging lakes to determine residual deposits of raw materials or for control soundings. If dual-frequency sounders are used, sedimented silt layers and their thickness can also be determined. With a multibeam echosounder, on the other hand, it is possible to record the bottom of a water body with a higher density of measuring points. In addition, a multibeam echosounder can be used for the investigation of dredging obstacles, shallows and for the quantification of scour formations. In combination with suitable positioning systems (PDGNSS) the river bed can be measured in centimetre raster and smallest structures <20cm at the river bed can be identified.

Scour Monitoring

The formation of flow-induced scours on the foundations of offshore structures is a frequent problem for their operators, as they have to ensure sufficient stability of the structures. Patzold, Köbke Engineers GmbH & Co.KG offer high-resolution fan-type plumb bob measurements for monitoring scour formation, which are repeated at regular intervals. By comparing measurements taken at different times, the extent and spatial development of scour phenomena can be verified in the form of difference plans or vertical sections in order to initiate scour protection measures in time.

Surface exploration

Hydrographic systems such as side-scan sonars or fan-type sounders are used for surface exploration of river bottoms. For side scan sonar data, the acoustic backscatter of surfaces is displayed monochromatically. In principle, the data have only a qualitative statement. A Sidescan Sonar (SSS) can also be used for mapping sediments and habitats or for the detection of natural obstacles such as blocks, rock fields, etc. on the river bed. However, lost objects and disturbing bodies such as fishing nets, ammunition or other anthropogenic objects can also be detected. The method is therefore ideally suited for area-wide exploration and for proving the purity of the seabed at hydraulic construction sites such as offshore wind farms. Modern, high-resolution fan-type plumb bob systems also provide data on surface backscattering and can map the smallest morphological structures on the river bed at microbathymetric level. With special computer programs it is possible to generate a simple soil classification of the river bed from the surface characteristics. By using representative soil samples, e.g. by using a Van Veen grab, it is possible to derive specific soil types and map them over an area.

Exploration Offshore / Onshore

Geophysical survey

Geophysical and geotechnical site investigation

For subsoil investigation in water, the engineering company Patzold, Köbke Engineers GmbH & Co. KG use, among other things, sub-bottom profiling methods for subsoil exploration in water. These include, for example, sediment echo sounders such as the parametric plummet or towed systems such as the Boomer or Chirp, with which the underground layer structure of riverbeds can be explored down to a depth of 20 m. In addition, seismic measurements can be used to identify objects embedded in the subsurface, such as boulders, stone fields, etc. Identified strata can be calibrated via corresponding exploratory drillings such as vibratory core drillings (VC) or pressure soundings (CPT), from which a building ground model can be created. In the land sector, geotechnical exploration methods such as pile-driving core or pile-driving soundings are primarily used. In addition, geophysical methods such as georadar or multipole geoelectrics are also used. In comparison to georadar, multipole geoelectrics penetrates cohesive soils and the groundwater table and can also be carried out in water, for example to determine layer boundaries below a river bed.

Explosive ordnance survey

Explosive ordnance detection
Explosive ordnance monitoring

Explosive ordnance detection

The engineering company Patzold, Köbke & Partner Engineers GmbH uses various probing methods to detect unexploded ordnance (UXO). By means of gradiometry, ferromagnetic objects can be detected both in water and on land. Depending on the problem at hand, electromagnetic surface soundings (metal detectors) are also carried out, which can also be used to detect ammunition containing aluminium. Detected suspicious objects are presented in the form of anomaly maps and tables. Special inversion methods are used to derive anomaly properties such as the depth and mass of an object. The identification, verification and recovery of marine ammunition bodies can then be carried out by Remotely Operated Vehicle (ROV) or diving personnel. In the case of ammunition bodies on land, specially trained technical personnel (holders of a certificate of competence in accordance with §20 SprengG) are used for this purpose. On land, area soundings are less used in the case of existing buildings or for greater exploration depths, e.g. in the case of hit dud bombs. In this case, borehole soundings in a specific grid are used instead. In the case of borehole soundings, the anomaly is displayed along a depth profile and an anomaly is correlated with surrounding borehole results.

For the investigation of areas contaminated with explosive ordnance, Patzold, Köbke Engineers GmbH & Co. KG uses different detection systems for the exploration of areas contaminated with UXO. Depending on the task, conventional handheld detection as well as computer-aided surface and borehole detection are used. (Link to 2.6) Occasionally, preliminary detection work on areas suspected of being contaminated with explosive ordnance during construction work is not feasible for various reasons. In this case, our specially trained, technical supervisory staff (holders of a certificate of competence according to §20 SprengG) will be deployed during construction. Our range of services includes:

Historical-geological research
Exploratory consulting
Stake out and measurement of probing and clearing areas
Explosive ordnance survey: Surface and borehole detection
Construction supervision by certificate holders according to § 20 SprengG
Identification and recovery of ammunition
Ordnance release documentation

Exploration Offshore / Onshore

Cable detection

Cable (depth) exploration (DOB - depth of burial)

Cable (depth) exploration (DOB - depth of burial)

Various geophysical methods can be used in combination to investigate cables buried underground. For example, magnetometric or electromagnetic methods can be used to depict the planar course of land and submarine cables, whereby the subsurface depth is essentially derived from model calculations. A more precise method for determining the depth of submarine cables, on the other hand, is provided by shallow seismic methods towed close to the bed of the water. The combined methodology of seismics and magnetometry can be used to verify, among other things, the minimum coverage of submarine cables. In contrast, cables resting on the bed of a water body can be explored by means of a side-scan sonar or a multibeam sonar. The course of cables is visualised in coloured area maps. For the representation of the depth position, profile sections along a cable course are particularly suitable.

Geotechnical survey

Exploration of deposits of loose and solid rock
Geophysical and geotechnical site investigation
Surface exploration

Exploration of deposits of loose and solid rock

Multipole geoelectrics is suitable for the exploration of gravel and sand deposits. Its fields of application are manifold and include the exploration of flood protection dams, aquifers and disturbing bodies in the underground. Depending on the task, geoelectric exploration is carried out in individual sections of up to 200 m in length with penetration depths of up to 40 m. Results of the geoelectrics are imaged in the form of a 2-D resistance tomography as a section of the subsoil from which soil types can be derived. A distinction can be made between non-cohesive and cohesive soils. In addition to geoelectrics, shallow seismic methods are also suitable for exploring deposits in water, with which exploration depths of up to 15 m below the river bed can be achieved. By combining seismic and geoelectric measurements, the quality of a deposit exploration can be increased. For this purpose, geoelectric and seismic results can be calibrated more precisely by means of exploratory drillings such as pile core soundings or spill and auger drillings. In the context of gravel and sand exploration, this forms the basis of a deposit-related interpretation.

ROV inspection

ROV inspection

ROV inspection

The onshore and offshore exploration of Patzold, Köbke Engineers GmbH & Co. KG undertakes a variety of tasks in which the use of Remotely Operated Vehicles (ROV) plays an essential role. Typical applications of a ROV are depth measurements of submarine cables by means of magnetometric or electromagnetic methods as well as investigations of the cleanliness of the seafloor after completion of work. This investigation is a requirement of the German Federal Maritime and Hydrographic Agency (BSH) when working in German waters. Furthermore, a ROV can be used for structural inspections, e.g. for the foundations of wind turbines, or for the inspection of explosive ordnance. As a rule, a ROV is equipped with a wide range of measuring instruments such as depth sensors, altimeters, a sonar, a grappler, lamps and underwater cameras. In addition, the ROV can be equipped with a variety of other measuring equipment, such as magnetic probes for explosive ordnance inspection, probes for cable depth determination, measuring instruments for determining the state of corrosion of underwater structures or devices for cleaning and flushing objects.

Against the background of high deadline and cost pressure, the construction of civil engineering structures in building construction and civil engineering nowadays requires a high level of interdisciplinary competence in control and coordination, which the client often cannot access in-house. In this case the involvement of an external project controller is recommended.

As experienced project managers, we provide building owners with a competent contact person who provides you with an overview of complex project processes and advises you in the selection and coordination of the project participants (e.g. object and specialist planners, implementing companies, experts). The project controller and his team recognize risks and possible obstacles for your project at an early stage and thus enable a target-oriented planning as well as a tight control and management of all upcoming tasks and measures.

We offer our clients not only practical experience and reliable know-how, but also additional added value through the bundling of our in-house fields of competence, from geology and geophysics, object and specialist planning to expert knowledge of explosive ordnance detection and public procurement law.
