This project was carried out by Menon Business Economics on behalf of the Node Cluster (Norwegian Offshore and Drilling Engineering). It entails a comparative value added analysis and an extensive international ripple effects analysis. The value added analysis makes use of Menon’s activity database for the Norwegian business sector and Menon’s offshore and maritime population. The international ripple effect analysis utilizes Menon’s advanced international ripple effect model, the International Total Effect Model (ITEM).
