GREEN SHIP OF THE FUTURE
Comprehensive retrofit-project with focus on optimisation of vessels by using already know technologies
A unique cooperation between the partners in Green Ship of the Future (GSF) network has highlighted the potential for energy optimisation of a mere three-year-old tanker. By implementing the energy saving solutions, the tanker will achieve a fuel saving of at least 17,5 %.
Danish Energy Consulting has participated in the first of three retrofit projects in cooperation with several member companies in the non-profit organization GSF. The projects aim to explore the possibilities of energy optimisation of different types of vessels using existing technology – a theme that is highly relevant in the international shipping industry, which is challenged by requirements for reducing CO2and GHG emissions.
17% FUEL SAVINGS ON NEWER TANKER
The first project was completed on a series-made tanker in the MR class, which was built in 2016. Despite being a three-year vessel, the retrofit project has shed light on several energy optimisation options that could reduce the vessel's fuel consumption by 17,5% with a payback period of less than 3 years. In this way, the tanker can achieve great economic and environmental benefits.
LACK OF FOCUS ON ENERGY EFFICIENCY CAN BE EXPENSIVE
The word ”decarbonization” can't be avoided in the shipping industry, and GSF's project shows that it requires a systematic approach to energy optimisation if greenhouse gas emissions from vessel transport are to be significantly reduced.
”When a new ship is being built, or an existing vessel is to carry out a retrofit project, one tends to focus on the economics of the individual solutions rather than systematically working on creating whole technical solutions that are the most energy efficient and not least financially good,” says senior project manager in the maritime department at Danish Energy Consulting, Ole Jakobsen.
Ole Jakobsen's task in the projects is to collect information regarding consumption and operation, etc. as well as make calculations of energy consumption to assess energy savings as well as ensure consistency between the chosen technical solutions in the retrofit projects.
According to Ole Jakobsen, the retrofit projects carried out in cooperation with GSF are a good example of how close cooperation between consultants, manufacturers and suppliers ensures optimal, technical solutions that increase energy efficiency and thereby reduce vessels' fuel consumption and optimise daily operations.
NEXT PROJECTS ARE UNDERWAY
Now that the first of the projects is successfully completed, it's time to look at the next two projects, which are a RO-PAX from DFDS and an LR-tanker from Maersk Tankers. The next two vessels are both approx. 10 years old, so here the expectation is that there is significant optimisation potential.
