The FEED will define the facilities needed for the ensuing engineering, procurement, construction, and installation bidding phase, while the surveys, including a geotechnical borehole survey at the location of the production facilities, will provide site-specific data for the next phase of engineering.
In operation, they have zero backlash and thus can attain and hold a set position with precision accuracy, ideal for the borehole survey work to be undertaken.
