Skilltrade was founded to provide vocational training to professionals who are affiliated with the offshore survey industry. Because of the demand for training in general, courses are now also given to personnel who have minimal offshore survey exposure. The training is focused on providing the individuals with knowledge fitting their professional competencies through a series of multi-level and multi-skilled courses, based on the industries own requirements and verifiable standards.

Hydrographic Surveyors and Geo-Scientists, each with a specific field of expertise, have written this Two-Volume Handbook. All examples detailed in the books are derived from situations encountered in their years as Surveyors.
