SIMAC have established a Student Forum with focus on green ship technologies. The forum consists of a number of SIMAC students writing their final project. The students study different topics related to on-board applications, problems or procedures of green ship technologies. Below is listed some of the project topics examined.
Which problems are there in estimating the fuel savings of trim optimisation at different draughts and speeds when no model test data are available for the ship? How can these problems be overcome and a calculation formula be determined on the basis of model test data from other ships?
”How does the route optimisation program VES (Voyage Efficiency System) affect the navigator’s decisions on RPM of the main engine onboard container ships in the shipping company A.P. Møller-Mærsk? Which improvements should be made to the program in order for VES to provide an improved route optimisation onboard?”
Which possibilities are there of installing wet scrubbers onboard?
“As the international maritime organisation (IMO) has set limits for maximum emission of hazardous particles from ships, I wish to raise and answer the following questions in my bachelor project:
- What will be the consequences of the determined requirements, Tier I, Tier II and Tier III, on the operation of a ship?
- Which adjustments of the daily operations should be implemented in order to meet the requirements?
- With a focus on a few technologies, more specifically selective catalytic reduction (SCR), can this technological improvement realistically be implemented and is it sufficient to reduce the emission from a ship to the required level?
Trim in the fore end of Maersk ships – which problems do the senior officers experience in their daily work as a consequence of the changed trim and how does it affect the operation of the ship.

Considering a future shortage of fossil fuels and a more strict environmental legislation, shipping companies have a both financial and moral incentive to look for alternatives to oil-driven engines. On careful consideration and investigation, we believe that, at present, the easiest solution would be to convert to gas propulsion. However, we do not believe this to be a permanent solution as fossil gasses will not last forever, and the production of biogas is not very energy-efficient and, moreover, insufficient.
We wish to investigate a shipping company’s possibilities to convert their ships from MDO to LNG propulsion and the consequences of this conversion.
Which operational problems occur in the cylinder lubrication system when switching between high and low sulphur fuel?
Which operational problems occur in the fuel system when switching between high and low sulphur fuel?
How is an optimal operation of the cylinder lubrication system achieved when switching between high and low sulphur fuel?
This bachelor thesis will focus on emission of SOx and “wet scrubber systems”. How a so-called wet scrubber system can wash out sulphur dioxide (SOx) from the exhaust gas from the combustion of fuel oil. The construction of the system will be presented as well as a part of the theory behind the function of the system. Furthermore, the environmental aspects related to SOx emission will be briefly dealt with.
“What are the advantages and disadvantages of diesel-electric propulsion of supply ships, primarily the possibilities of meeting DP (Dynamic Positioning) redundancy requirements. Why is diesel-mechanical propulsion still the most common in supply ships.”
