Nautisches Buero Bremen was founded in 1986 by Capt. John P. Marcus as a small business enterprise.

Activities started mainly with construction supervisions and special marine operation consultancy.

In the end of the 80th the founder became member of the sea trials team of Bremer Vulkan Werft in Vegesack.

From 1992 on he acted as sea trials captain on behalf of this yard.

Specialising on this business segment John Marcus developed concentrated sea trials programs and sophisticated methods cutting non-productive and therefore expensive sea trials time to two-third. This advantage was possible by using own developed measurement programs, becoming compass adjuster and being appointed as sworn marine surveyor. This concept was honoured by various shipyards and time-by-time Nautisches Buero Bremen became sea trials partners for up to ten Europe ship builders.
