Fishing Vessels
Naval Consultant Herman Jansen has designed a wide range of vessel types for the professional fishing industry over the years. The most successful and well-known design is the Concorde series — a 40 to 45-metre beam trawler concept originally developed for the flatfish fishery.

Inspections and Classification Support
Naval Consultant Herman Jansen BV carries out inspections under the supervision of all internationally recognised classification societies. In addition to mandatory surveys, we also offer pre-purchase inspections across various maritime sectors.

Changing a vessel’s flag requires specialist knowledge of legal frameworks, documentation and coordination with various authorities. Naval Consultant Herman Jansen has years of experience in managing the complete flagging and re-flagging process for (fishing) vessels across several EU and EEA member states.

In the event of damage or even a collision, we can take a great deal of work off your hands as owner or operator. With our technical expertise, we manage the entire process — from the initial report to final completion.
What do we handle in the case of damage or collision?

International Energy Efficiency Certificate (IEEC)
