Sammendrag
The IMO 2023 greenhouse gas (GHG) strategy have the ambition to reduce the greenhouse gas emission from vessels worldwide to net-zero by 2050. The emission reduction will be stepwise regulated with a goal of achieving 40% reduction compared to 2008 values by 2030. Ship owners must act and implement energy efficiency measures on their vessels to gradually reduce the fuel consumption and emission. The two categories of energy efficiency measures are technical and operational.
The background of this thesis is to reveal the operational energy efficiency conducted by the officers in charge on board and the communication with the vessel manager in the ship management company. The aim of this thesis is to investigate how the human impact can impose the results in GHG reduction when operating the energy efficiency measures. The specific topic in this thesis is narrowed down to explore the vessel managers role when managing a dual fuel Newcastlemax bulk carrier in cooperation and communication with the officers in charge, and how the operational energy efficiency can be improved on-board.
A single case study was utilized as the research method, and the single case involved the vessel manager`s role acting on behalf of the ship management company and the interaction with the ship officers on-board a 2023 built dual fuel Newcastlemax bulk carrier with 11 similar sister vessels.
The data collection was done by conducting two personal interviews with the vessel managers in Norway and qualitative E-mail questionnaires addressed to a 3rd vessel manager, one chief engineer and one captain. The transcript of the collected qualitative data was evaluated and revied by breaking down and comparing the respondent’s data to reveal categories and codes with theoretical significance for the research questions.
The findings revealed in the results showed that the lack of knowledge and cultural differences within multinational crew and officers could impose the results negatively regarding energy efficiency operations. The lack of knowledge utilized the need of ship specific energy efficiency training in addition to the general in-house computer-based training (CBT). A bonus or other incentives for motivation in performing energy efficiency saving with good results should be evaluated by the ship management company. Extension of on-board contracts should be kept to a minimum since it can impose stress and fatigue among the officers in charge of conducting energy efficient operations (EEO), resulting in less energy efficiency awareness.
Key words: Energy efficiency awareness, knowledge, human impact, communication, training, energy efficiency measures, ship, and officers.
