Premas

What Premas does

Premas AS is a Norwegian maritime and offshore software company founded in 1986 and headquartered in Aalesund, with a regional office in Bergen. The company develops and sells two enterprise software platforms: Premaster, a maritime maintenance and HSEQ management system for vessels and offshore installations, and Maisy, an asset integrity and rental management system targeting oil & offshore service companies and land-based industries. Both products run on a distributed architecture using replicated databases that synchronize between vessel/offshore installations and shore-based office systems, enabling crew and shore personnel to work from the same operational dataset regardless of connectivity. Premaster GO is a mobile extension providing crew-level access to certificates, maintenance jobs, and event reporting on tablets and phones. Supporting the platforms is a Data Services business built on a proprietary database of over one million maritime and industrial equipment records used for data enrichment, cataloging, and migration. The company's customer base spans fish farming, fisheries, offshore support, passenger vessels, coast guard and search & rescue, oil & offshore services, and land-based industry, with named customers including Torghatten Nord, Royal Greenland, Redningsselskapet, Island Drilling, and The World cruise ship. Premas holds a market-leading position for Safety Management Systems in Norwegian aquaculture service vessels.

The company operates a direct enterprise sales motion with quote-based pricing on annual subscription cycles, supported by consultancy-led implementation and training services. Revenue streams include software licensing (Premaster and Maisy subscriptions), professional services, and data monetization. In September 2024, Premas merged with Star Information Systems AS in a partnership backed by Norwegian private equity firm Longship, combining two established maritime software vendors under unified ownership with integrated sales, marketing, finance, and HR functions and a combined footprint of five global offices. The company is led by CEO Thor Arhaug, with named Sales Manager (Einar Olsen) and Services Manager (Leif-Arne Remøy) overseeing customer engagement and delivery. The combined entity is positioning itself as a leading global maritime software provider covering Asset Management, Maintenance, QHSE, Supply & Logistics, and Projects.
