Abstract
The offshore support fleet, crucial for the oil and gas operations on the Norwegian Continental Shelf, faces a pressing need for decarbonization. Platform supply vessels (PSVs) contribute ca 1 million tonnes of CO2 annually, making them the largest greenhouse gas source in the offshore logistics supply chain. The government's directive to implement zero- and low-emission solutions by 2030 sets the stage for transformative change. The goal of the competence-building project ZeroLog is to develop a framework for unified analysis of future ship modifications and vessel operations. The research partners will advance their efforts on the topics of energy system and hydrodynamic vessel performance, fleet level and operational planning, vessel design, resource sharing and cooperation. All partners together will work towards identifying and analysing the relevant fleet compositions and renewal strategies towards 2030 and 2050 goals.
