1. Issues Relating to Safety management of GHG Less Fuel for Ships (2:30-3:10 PM) UK Time
The talk begins by examining the relation between climate change and shipping before defining the term “GHG-less” (Green House Glass) fuels and review possible fuels. Fundamental characteristics of safety is then explained before assessing available methods for safety management. The Generic Safety Management Circuit (GMSC) approach is outlined and its application is given by a brief illustrative example. The main conclusion is safety must be given proper attention at all times and especially when new fuels are introduced when there is little operational experience.
2.Development of A Maintenance Framework Based on Component Critically Analysis (3:10-3:50 PM) UK TimeThe demandin
nature of the operational requirements of Naval ships leads to rapid deterioration and decline in operational reliability especially that of machineries as they are pushed to operate at the limits of their operational envelop. This therefore results to high levels of wear leading to performance degradation and frequent failures of critical ship equipment components. In this regard it is important to identify which machinery component and failure events are most critical to ship’s availability that can be improve through other alternatives in maintenance, inspection, operation, and training. Therefore, this research presents a combination of tools to identify ship critical component and faults by analyzing ship machinery operation records. The tools employed are, Dynamic Fault Tree Analysis (DFTA) to identify critical equipment reliability, Failure Mechanism Effect and Criticality Analysis (FMECA) to identify Mission Critical Component and Machine Learning approach based on Artificial Neural Network (ANN) was used to analyse the machinery performance data. The outputs from the DFTA, FMECA and ANN were used to obtain vital insights and inputs for Bayesian Belief Network (BBN) to help with maintenance decision support system platform for the generator that can be utilized for the systems. A case study analyses on a 400KVA diesel generator used for power generation onboard an Offshore Patrol Vessel (OPV) was conducted using the methodology
3.Prospects of Alternative Fuels In Energy Shipping (4:00-4:40 UK Time)
The world is embarked on the process towards the energy transition for decarbonization. The main way to achieve this objective is through electrification with renewable energies, however there are several sectors that are difficult to decarbonize directly and it is believed that hydrogen and alternative fuels can play an important role in this process. Examples of these sectors are maritime transport, aviation, long-haul transport and heavy industry. Hydrogen is bound to be a highly demanded commodity in the main industrialized regions. In this presentation we will discuss the global energy landscape, the expected uses of hydrogen and alternative fuels in the energy sector, the need for its transport, along with some economic insights. Finally, the main research lines of the research group the presenters belong to will be summarized.Speakers

- Abdullahi Abdulkarim Daya
Abdullahi Abdulkarim Daya is a PhD research student at the University of Strathclyde, Department of Naval Architecture, Ocean, and Marine Engineering. He is a serving marine engineer officer in the Nigerian Navy and has extensive experience as an engineering officer onboard different class of ships, fleet maintenance depot and ship spare parts procurement management. Over this period, he has been privileged to participate in wide variety of activities on ship life cycle management from initial design conception, procurement, acceptance trials, through life management to life extension process. His research interests include ship system condition monitoring, marine systems risk and reliability, ship operations, maintenance and asset management. I am currently working on the development of a maintenance framework using artificial neural network and expert system for optimal maintenance planning on board ships.
