Since 1996 I have operated as self-employed consultant in offshore survey, positioning and software design.

Mainly I'm serving as offshore Client Representative or Marine Warranty Surveyor on various survey, construction vessels and drilling rigs.

In parallel I'm working with my own portfolio of software, marketed on this web site.

Until May 2012 I had a 25% occupation as Assistant professor at the Maritime University in Tromsø, where I teached Geodesy, Electronic positioning systems, ECDIS and AIS.
