Energy efficiency has become and will remain the key differentiator in shipping for the future. This is mainly due to high bunker costs, low global transport demand and the steadily increasing environmental requirements from legislation. Thus, in order to stay competitive, shipping companies are required to work much harder on the energy efficiency of their vessels.The Swedish tanker company Laurin Maritime has recognized this industry requirement and is working constantly on further improving the energy efficiency of their fleet. Part of this continuous improvement initiatives are the installation of energy efficiency systems by Marorka on large parts of their fleet.An additional propulsion optimization module has been implemented on Laurin Maritime's three C-type tankers. So far the company has not registered any significant benefits resulting from this installation. Thus, this paper aims on evaluating its overall performance on these three ships and the benefits in energy management, which this additional Marorka module provides to the company. Based on the evaluation results recommendations for further improvement are provided. The information provided in this paper is mainly based on a number of interviews that have been conducted with both the shoreside management as well as the responsible chief engineers of Laurin Maritime. In addition the system manufacturer Marorka has been interviewed online as well. Also a literature review has been carried out for collecting further information.
