Preface

This thesis is submitted to the Norwegian University of Science and Technology (NTNU) for partial fulfilment of the requirements for the degree of Philosophiae Doctor. The work was carried out at the Department of Marine Technology at NTNU, in Trondheim, Norway. Professors Harald Ellingsen and Ingrid Bouwer Utne from the Department of Marine Technology at NTNU were the main supervisor and cosupervisor, respectively. NTNU funded the doctoral work. Norwegian Shipowners’ Association Fund and Anders Jahre’s Grant provided partial funding for attendance to conferences during the research period. The target audience of this work include researchers and practitioners interested in the following areas: energy efficiency and emissions of fishing vessels, Norwegian fisheries, energy efficiency gap in shipping, LNG-powered vessels, Bond Graph method, institutional interactions between environmental regulations, and systems engineering.

Summary

Operation of fishing vessels is energy demanding. On one hand, fuel costs and preference of customers for buying “green” seafood products challenge economic feasibility of fisheries. On the other hand, environmental concerns and regulations further complicate the situation. All these call for an improved environmental profile within fisheries. This PhD study aims at contributing to the research body by focusing on energy efficiency and emission reduction within fisheries. The topic of emission reduction spans across several disciplines. Different factors, such as vessel characteristics, regulations, and social aspects affect fuel consumption and air emissions of fishing vessels. As a result, this PhD study is interdisciplinary. Since the focus is on several disciplines rather than one specific area, systems thinking has dominated this study. In this way, the focus is on “the big picture” and various factors and interactions that affect energy consumption and emissions rather than on one specific factor. First, this study focuses on reducing the air emissions indirectly by increasing energy efficiency of vessels. To set a baseline, it statistically analyses energy efficiency of Norwegian fisheries in recent years. Then, through literature review and focus groups, this study investigates barriers that prevent the adoption of energy-efficient measures that are cost-effective. A framework is also offered to assist ship owners and operators in alleviating these barriers. Then, the study focuses on increasing the knowledge of ship owners and operators about the energy efficiency of their vessels and available measures in order to facilitate their adoption. In this regard, the power system of a fishing vessel is modelled and simulated to study energy consumption for various operations. Second, this study explores the possibility of fuelling fis
