“…Although the combustion process is responsible for the power generation, it is also the cause for emissions of GHG and other components, including carbon monoxide and dioxide (CO and CO 2 ), water vapour (H 2 O), nitrogen and sulphur oxides (NOx and SOx), unburned hydrocarbons (HC), as well as particulate matter (PM) [6].…”

“…They require a highly dynamical response, including Dynamic Positioning (DP) with high levels of reliability and safety [15], which is generally associated with power source redundancy and operation in low loads (compared to optimal loads). Also, OSVs have large variations in their power demand, with different operational modes, making it hard to keep the engines operating within desired optimal ranges [6].…”

“…According to [6], until recently, the majority of energy management control in the industry was based on rules/heuristic techniques. Rule-based techniques require the knowledge of the system and experience to exploit the potential of hybrid systems.…”

“…The energy management objectives depend on the vessel type, priorities, and load profiles, requiring specific control policies given the application. For example, navy vessels require a system able to supply power to balance short-pulsed loads related to weapons, ferries for passengers require low emissions and noise, while tugboats have multiple operational modes, with a requirement of full bollard pull during vessel assistance [6].…”

“…However, this is not true for all components. As mentioned in [6], the NOx emissions and fuel consumption can be conflicting goals. Some of the more efficient operation regions of engines also increase the emissions of NOx.…”

Climate concerns, regulations, and fuel costs are driving higher efficiency designs in the shipping industry. Research works suggest that hybrid power systems can be a viable option to reduce fuel consumption and emissions. However, more studies are required to analyze its net gains in different applications. In this work, numerical simulations of power systems are performed in a causal approach, including a non-hybrid or base case and a hybrid case, for a diesel-electric Platform Supply Vessel (PSV). Dynamical and static models are considered for the power sources, namely, diesel generator sets (gensets) and a lithium-ion battery pack connected through an AC electrical network. For the Energy Management System (EMS) of the base case, an optimization of gensets is performed, and for the hybrid case, a rulebased control combined with an optimization of the generators is considered. The analysis shows, for the case study, that the greatest potential for battery usage is achieved in near port operations. Cleaner operations were allowed in these regions due to the increase in energy efficiency and the disconnection of generators. A fuel consumption reduction of 6.35% and CO 2 emission reductions of 5.81% were achieved for the complete mission. Also, an increase of 1.73% in the overall energy efficiency was accomplished.

Environmental sustainability has become a significant policy concern in global maritime transport in recent years. To achieve high energy efficiency and low emissions, the all-electric ship (AES) integrated with an energy storage system (ESS) is believed to be one of the most promising technologies for complying with environmental regulations. The traditional rule-based power management system (PMS) I would like to thank my co-supervisor, Prof. Tegoeh Tjahjowidodo from Katholieke Universiteit Leuven, Belgium and Prof. Michael Lau from Newcastle University in Singapore.
