The WNV marine surveying consultancy unites the expertise of three reputable companies:
Van Woerkom, Nobels & Ten Veen
Expertisebureau Van Rees BV
Expertiseburo Jos Ceelen

Each unit operates independantly but administrative facilities, expertise and manpower are grouped.

Van Woerkom, Nobels & Ten Veen has a long tradition of excellence, starting over 75 years ago when it was founded as a one-man surveying business in the Dutch town of Sliedrecht, the historical birthplace of modern dredging. The company has evolved into a thriving international marine expertise bureau with a world-wide network of surveyors. While our core business still lies in the dredging sector, we have extensive experience in many other fields, such as sea-going cargo shipping and towage approval certification.

Expertisebureau Van Rees BV is specialized in providing Class inspections and on/off charter surveying of wet contracting equipment for inland waterways. The company brought thirty years' experience and a solid client base to join forces with WNV in 2000.

Expertiseburo Jos Ceelen, as well as being an all-round marine surveying company, is specialized in land-based equipment such as earth-moving machinery, waste recycling installations and agricultural equipment. Ceelen also provides a superintendency service for newbuilding and refitting jobs.

WNV is based in the Dutch town of Sliedrecht, near Rotterdam, and is certified with NEN-EN-ISO 9001:2000.
