Hydrographic Survey Category B Course

recognized by the International Hydrographic Organization

Category B training, offered by the CIDCO, covers all aspects of hydrography: geodesy, positioning, underwater acoustics, bathymetry, tides and water levels, hydrographic data management.

This course offers students a quality training based on a combination of theoretical learning and practical fieldwork.

The training is recognized by the International Hydrographic Organization (IHO, Category B) and meets the S-5 standard of competence for hydrographers.

Upon completion of the training, a certificate is issued attesting to the successful completion of an IHO recognized Category B training program.

There is currently a strong industry demand for hydrographers to conduct an increasing number of hydrographic surveys. Whether it is offshore, coastal or inland, the marine industry (dredging, construction) or the petroleum industry, hydrographic surveying companies are quickly growing.

IHO-accredited training can give you the ability to work around the world in a rapidly growing and sustainable field.

As a Class B Hydrographer you will be working for companies or government agencies that have quality standards recognized by the IHO or by the industry itself.

The CIDCO hydrographic survey training is delivered over a 40-week period and consists of three main parts. The theoretical part, the practical field exercises and the Final Field Project (FFP). The theoretical part of the course is given in "e-learning" formula. It takes place over a period of 33 weeks, from October of each year to mid-June of the following year. In total, 9 modules are covered during the theoretical training. It is composed of weekly hours supervised by CIDCO teachers who explain the important concepts of the lessons (readings) and who lead the students to apply the theoretical knowledge and to complete the theoretical component (practical exercises and tutorials).

For each module, participants are required to complete assignments to assess the knowledge acquired during the theoretical and practical sessions. Evaluation is also done through quizzes after each lesson and exams that must be taken throughout the e-learning period of the program.

The practical field exercises (2 weeks) take place at the Rimouski marina and on the St-Lawrence River. Their objective is to put into practice the theoretical concepts acquired during the theoretical training and allow the students to work with and manipulate the different hydrographic equipment.

The Final Field Project (FFP) lasts 5 weeks and takes place in class and in the field, at the Rimouski marina and on the St. Lawrence River. The FFP represents the culmination of the training where students will perform various hydrographic survey tasks. They plan their data acquisition, acquire different hydrographic data, process the data and produce the corresponding products, all under the supervision of the CIDCO teachers.
