From finance in London to shipping professor at NHH
Haiying Jia was recently appointed full professor at NHH. She is an expert on shipping and finance. During her PhD in UK, she worked as an investment analyst in London.
Maritime transport applications in an operational efficiency perspective
On Tuesday 21 February 2023 Gabriel Fuentes Lezcano will hold a trial lecture on a prescribed topic and defend his thesis for the PhD degree at NHH.
The thesis explores the impact of operational efficiency solutions for two shipping applications: Bunkering (refueling) a vessel operating in the tramp market and reducing greenhouse gas emissions from efficient arrivals at chokepoints.
In the first two chapters, the focus is on fuel management and the effect of waiting times on fuel selection. The first chapter outlines a new framework for gathering data on fuel efficiency using vessels Automatic Identification System (AIS) data and machine learning and generates statistics for fuel operations in the Mediterranean Sea. The results validate earlier results and hypotheses in the literature on bunkering operations, commonly obtained from qualitative methods.
The second chapter explores what is the value of efficiency in an optimal bunkering management plan for tramp ships?
The research question is explored by a set of experiments using different settings a shipowner would face if trading in the Mediterranean Sea. The experiments are based in a multistage stochastic model with consideration of stochastic waiting times and stochastic bunker prices. The results suggest that when there is significant uncertainty in waiting times, a decision based solely on price could result in significant losses. The study provides insight for shipowners to evaluate waiting times at potential refueling ports as part of their standard practice.
Finally, the third chapter looks at the impact of reducing speed on GHG emissions at maritime chokepoints, such as canals. Reducing speed is an operational measure with a high potential to reduce emissions. The study shows that more efficient scheduling at chokepoints, such as the Panama Canal, can significantly impact overall emissions.
From a qualitative point of view, this work highlights how many of the well-known contractual barriers to operational efficiency in ports are mitigated in the case of canal operation, making this a suitable avenue for the gradual implementation of policies driven by the need for emission reduction.
