RAMONA – regularity

The RAMONA project focuses on regularity and deliverability of the Norwegian gas transport system.

This collaboration embraces researchers at the University of Bergen, the Norwegian University of Science and Technology (NTNU), the SINTEF research foundation, Statoil, Gassco and CognIT.

The aim is to develop methods for optimising regularity and deliverability in Norway’s natural gas production and transport system. 

Efforts will be made through the project to fill the gap between existing methods and future requirements created by the liberalisation and integration of the European energy market.

Particular emphasis is being given to improving predictions of the regularity of the production and transport system, by taking into account pipeline flow and pressure, aging, maintenance and other operational conditions.

One objective is to contribute to optimal planning and operation of the system in relation to capacity utilisation, maintenance and future infrastructure investment.

A total of six research fellowships are planned, of which two will be at the UiS/Iris.

The project has been allocated NOK 20 million by the Research Council of Norway and NOK 10 million from Statoil and Gassco over a five-year period.
