Welcome

For 27 years, VBW Weigt GmbH (Survey Office Weigt) has been a reliable service provider in the fields of engineering surveying, hydrography (inland waters, nearshore and offshore), geotechnical engineering and satellite geodesy.

Company Profile

Since the German Federal Maritime and Hydrographic Agency (BSH) gave the green light for the first offshore wind farm in Germany, the VBW service spectrum has continuously shifted towards offshore engineering for the planning, installation and maintenance of offshore wind turbines and their export cables.

With a redundant portfolio of measurement technology (geophysical and geotechnical) as well as own measurement vessels, customer-specific complete or selective services are provided according to national and international standards. VBW is ISO 9001, ISO 45001 and ISO 14001 certified.

The surveying office is based in Ziesendorf and has further branch in Hamburg.

We are proud to be able to count almost all well-known participants in the industry segment “Offshore Wind” among our long-term customers.

 

SERVICES

The range of services includes the preparation and implementation of geophysical and geotechnical investigations in the North Sea and Baltic Sea and is rounded off by georeferenced and laboratory supported evaluations as well as expert reports according to the highest offshore standards.

ENGINEERING SURVEY

Engineering surveying is the core area of applied geodesy and is a necessary and important task in connection with the realization of a construction project - whether in civil engineering or structural engineering, whether on land or in water.

Geotechnics

In particular for subsoil investigations of offshore wind farms and the associated cable routes, the portfolio has been expanded to include the corresponding technology and decades of geological know-how. For the core extraction of marine sediments for geotechnical laboratory investigations and lithological stratification, we have a Vibro Corer (vibratory core device) at our disposal, and a CPT for the associated mechanical parameters.

GEOPHYSICS

Our range of geophysical services has already been used in more than 80% of the wind farms in Germany's North and Baltic Sea territories that have already been approved and are currently being approved. In this regard, our clients have primarily tasked us with surveys to be conducted in line with the BSH standard "Ground Investigations for Offshore Wind Farms":

Vessel positioning

As soon as ships are used in the course of construction work, exploration of subsoil or search for explosive ordnance, the demands on positioning accuracy are significantly higher than in general shipping.

GIS Geographic Information Systems

Geographic information systems allow you to systematically organize and manage your digital geometric and factual data as well as a variety of possible spatial analyses.

CONSTRUCTION MONITORING

No construction project on land or at sea today can do without detailed and immediate documentation of the work progress and the associated logistics. Professional and continuous construction supervision is indispensable to ensure this.

Range of services

Engineering surveying describes various measurement methods and uses a wide range of measurement sensors. Especially satellite and laser technologies offer a wide range of applications within the field of engineering surveying due to the permanent updating and improvement of the systems. In the course of the erection of offshore foundations, e.g. for wind energy plants, we have made the construction-accompanying surveying on erection platforms and work ships one of our main fields of activity for several years now. We develop customized measurement concepts and equip platforms and ships with the necessary sensors.

Range of services

VBW Weigt GmbH uses modern technologies to position vehicles with centimeter accuracy. The location of the project area and the distance to the coast are not important. In addition to the global position, further information about the ship's position is determined in real time and displayed graphically and numerically. Each point of the ship is precisely defined with coordinates at any time. With the help of special positioning software, the ship's guidance is supplied with information about the current spatial position of your vehicle in real time. The complexity of the positioning system varies depending on the requirements and type of ship. Only tested sensors and systems are used which have proven themselves in numerous measures in tough offshore applications.

Areas of work

  • ship measurement
  • Build-accompanying positioning (RTK)
  • installation documentation
  • Positioning of UW systems (USBL)
