 In order to reduce fuel consumption and increase efficiency, our systems engineering experts specialize in simulating and optimizing your vessel's systems. Modern vessels consist of a complex arrangement of many different systems. A vessel where all systems are optimized to work together as efficiently as possible can significantly increase fuel utilization.
Our methodology is built on Marorka’s specialized energy system simulation and optimization software Marorka EDT. The Marorka Energy System Design Tool (EDT) system allows us to efficiently build mathematical simulation models of energy systems for analyzing and optimization purposes. Running the simulation models highlights the energy consumers and their behaviour in the different operating modes.
Based on this holistic simulation FutureShip conducts a number of investigations to optimize the fuel utilization of your vessel including:
- Machinery simulation to predict fuel consumption for different operating modes and components
- Analysis of auxiliary engine layout including number of engines, subsequent output, and interaction with alternative generation systems
- Optimization of electrical systems with advanced layout for a frequency converted e-system
- pecifications for alternative energy sources
- Onboard monitoring of systems to assess performance compared against simulation results
Principle systems components typically investigated by FutureShip:
- Main engine
- Auxiliary engine
- Auxiliary systems (fuel system, lubrication system and cooling system)
- Other e-driven systems
- Additional energy sources
Examples for increasing the efficiency through changes in the systems' arrangements:
- Recovery of exhaust gas heat
Energy in the exhaust gas is converted to electrical energy using steam turbines or direct turbo generators. As a result, the output required directly from the installed auxiliary engines can be reduced and efficiency gains of the entire system can be up to 10%.
- Monitoring of the main engine
Performance monitoring allows early detection of abnormalities. Fuel savings of up to 4% are possible through correctly timed maintenance intervals. Additional benefits can be reached through condition-based maintenance and inspection. Due to the increased efficiency and an accurately determined "Sea Margin" it is often possible to select a smaller engine. For ships in service the engine can be adapted to the reduced power requirement through appropriate measures - such as derating and turbocharger and cylinder cutout. Close cooperation with engine manufactures ensures a maximum utilization of potential efficiency gains.
- Frequency converted e-system
An advanced layout of the electrical system can be achieved where consumer output is adjusted by frequency control rather than conventional throttle control. Savings of 30-40% can usually be achieved. Example: A pump with capacity of 45m3/h operates in normal onboard operation only at a rate of 25m3/h. With a frequency converted system, this pump requires an input of 6.1 kW compared to 9 kW with a conventional throttle control; a saving of 32%.
