Our journey

A company steeped in tradition is preparing for the journey ahead.

Where we come from

The company’s history goes all the way back to 1960, with development, production and marketing of film projectors. The introduction of new video technology led to production of the original products gradually being scaled back. To utilize its expertise in fine mechanics and electronics, the company searched for new business areas.

In 1975 a new tank measuring system was incorporated into a new instrumentation department. The company now also changed its name to Norapp AS.

By the early 1980s, a significant number of tank monitoring systems had been sold and installed to the land-based oil industry.

In 1984, the Tiedemanns Group took over the company’s operations. Norapp expanded its product range to include addition and automation systems for oil depots.

In the 90’s we invested heavily in innovation through product development with new and advanced software solutions called Accella.

In the years that followed, the company established itself as a leading supplier of automation and administration of depots within the land-based oil and gas industry under the name Petro Online. Since 2022, Morten Solberg became the biggest shareholder in the company. 

Today, Accella is used at more than 70 large tank and distribution facilities throughout the Nordics, including the Faroe Islands, Iceland and parts of the Baltics.
Where we are headed

The global energy sector is undergoing a transformation, and its essential that the storage terminal industry keeps pace with this. We are no exception. Our ambition is to be part of this journey for the years to come.

First and foremost, we must secure and develop our existing customers’ socially critical installations, where Accella TAS is the management system for large liquid process facilities.

At the same time, we will position Accella for a broader market. Our expertise over many years is reflected in the Accella solution. Together with great partners and collaboration we can deliver Accella globally.
