Geotechnical services

Herman Senior has many years of experience in different kinds of geotechnical works. A few examples of the works that can be done on board of our vessels:

  • Hydrographic survey
  • CPT
  • Vibro core

All of our vessels are equipped with a moonpool so survey equipment can be installed without any problems.

Our vessels are also equipped with the latest amenities for easy connection of survey equipment. There are connections for GPS applications and there is a special 19-inch survey rack where all the equipment can be safely stored and connected to the main power of the vessel. 

On many projects in the past the vessels from Herman Senior have functioned as a survey vessel in some cases combining the survey works with ploughing, towing or other services. Because the survey pole is easily adjustable in height there will be no risk of damaging the survey equipment that is installed on the vessel. 

Our fleet of ships is very versatile and all vessels have a fixed crew on board for better than average performance.
