Warranty Services

Since the late 1970’s Van Woerkom, Nobels & Ten Veen is involved in a vast variety of marine transports and associated subsequent inspections; eventually this has led to our dedicated department WNV Warranty Services.  Acting on behalf of owners and underwriters we approve worldwide towage and stowage transports.

During the years we gained experience in reviewing and accompanying the marine and inland water transports of amongst others new building hulls, offshore units, semi-subs, all sorts of dredging vessels and equipment, harbour and container cranes, etc. Not only with oceangoing transport projects, but definitely also with delicate short distance or coastal transports we are highly familiar.

To conduct transport inspections worldwide and to provide our consultancy and input professionally a team of well-trained surveyors is available. Because of this broad surveyors pool and because of our almost continuous in-field worldwide presence we are able to respond fast and efficiently.

For each unique transport during the engineering, design, preparation and actual transport stages we work from a project team where at least 2 surveyors and an office based assistant are part of. We consider our job not finished after issuing the (s)towage approval certificate, but follow the transport and provide assistance up to its completion. Final and most important goal of our involvements is a successful fulfilment of the transport.

Unlike other work methods in the marine warranty industry our approaches are practical and down-to-earth, combined with a theoretical background, always keeping in mind that the entire transport should be carried out with the maximum achievable combination of reliability, safety and efficiency.

  • Towage Approval Certificates
  • Long - term Towage Approval Certificates
  • Towage Manuals
  • Review of procedures and method statements
  • Advice

After thorough preparation and positive inspections of tug and towed object and subsequent approval of the spread, a Towage Approval Certificate will be issued.

It is common practice and normal procedure for WNV to set and discuss clear and realistic conditions and recommendations for the towage. Only after successful delivery our involvement stops; throughout the entire voyage we monitor and advise the tow.
