Successful projectsWelcome
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.
