Optimization of electrical energy production in off shore installations (EOOS)
The overall goal of the project is to suggest measures that reduce the energy consumption and emissions in the range of 15-20 percent in off shore applications. The Draugen oil and gas off shore platform in the Norwegian Sea operated by A/S Norske Shell is considered as a first practical case study within this project. Read more.

The influence of fuel sulphur on the operation of large two-stroke marine diesel engines
Large ships that operate outside the near coast areas—known as the Emission Controlled Areas—are allowed to burn heavy fuel oil that contains a few percent of sulphur. After combustion of a fraction of the fuel, sulphur is converted to gaseous SO3 in the combustion products in the engine cylinder. SO3 is problematic as it is known to condense as corrosive sulphuric acid (H2SO4) and reduce the lifetime of cylinder liners. Condensed acid is partly neutralized by base additives in the lube oil from which corrosion is also hampered. Read more.

D
esign and optimization of highefficiency energy systems for offshore platforms
The project has dealt with the possibility of improving current and future energy systems on offshore platforms. At present, the oil and gas extraction sector is responsible for a significant share of the CO2 emissions, representing about 4 percent of Denmark’s and 26 percent of Norway’s emissions, respectively. In this context, reducing the energy use on offshore facilities and improving the energy conversion system would reduce fuel consumption and as a consequence lower CO2 emissions. Read more.

Design and modelling of innovative machinery systems for large ships
Eighty percent of the growing global merchandise trade is transported by sea. The shipping industry is required to reduce the pollution and increase the energy efficiency of ships in the near future. There is a relatively large potential for approaching these requirements by implementing waste heat recovery (WHR) systems. Read more.

Modelling of innovative gas turbine and waste heat recovery systems for offshore platforms
This project focused on exploring the opportunity of implementing bottoming units, e.g., organic and steam Rankine engines, to recuperate the heat dispersed by the gas turbines installed on board. Novel design methods based on evolutionary multiobjective optimization algorithms were developed to adapt onshore technologies to offshore applications. This allowed projecting compact and light waste heat recovery units, while at the same time pursuing high efficiencies and reliability. Read more.
