Arash is a PhD student at the department of hydraulic engineering at Delft University of Technology. His expertise is in logistics management and he’s currently working on optimising the port processes’ efficiency when quantifying a trade-off between port accessibility and maintenance. The expected result from his research is selecting the optimal strategies for port maintenance. Arash’s previous research has focused mainly on safety assessments in ocean engineering projects and developing sustainability in port management systems.

Simulating for sustainability: alternative operating strategies for energy efficiency

In the 2015 Paris agreement, countries committed to implementing measures to reduce greenhouse gas emissions to limit global warming. For the maritime industry specifically, the International Maritime Organization (IMO) has proposed measures for energy efficiency of vessels and candidate measures regarding fuel choice and speed optimisation. This article aims to contribute to the latter by showing how logistical simulations can be used to optimise fleet operations. We will illustrate this in the form of a conceptual case using one cutter and a range of barge fleets. Running simulations with all possible fleets, we will demonstrate the value of extra energy-based alternatives to challenge the fastest, cheapest and most flexible alternatives.
