Skilltrade has provided Hydrographic Survey training since 2000. The Category B course in Hydrographic Surveying began in 2007 in coöperation with STC in Rotterdam. The course was first recognized by the FIG/IHO/ICA International Board on Standards of Competence for Hydrographic Surveyors and Nautical Cartographers (IBSC) in 2008. Since it began, Skilltrade
has trained over 230 individuals from various countries around the world in the field of hydrographic survey. The Category B course has been enthusiastically welcomed and endorsed by a range of international authorities and market leaders operating in the marine oil and gas industry, coastal and port environment and hydrographic fields. In January 2014 the course was transferred to a new location, the Nova Nautical College in IJmuiden. Addressing demands of a changing industry while adhering to ISBC requirements, the program is under continuous revision.
