22 Apr '09 Successful Marorka conference in Greece
Over 70 people, representing 50 shipping companies, attended Marorka’s conference last week in Piraeus, the shipping hub in Greece. The event was titled Marine Energy Management – the only way ahead, emphasizing the imperative need for the shipping industry to make a long-term commitment to energy efficiency as a means to reduce cost and emissions of harmful greenhouse gases. The interest in the subject of energy management was evidenced by the excellent attendance and fruitful discussion on this pressing topic. Uncertainty regarding the future price of fuel, environmental concerns and anticipated legislation is high in shipping companies’agenda nowadays.
An elite line-up of guest speakers included Dr. Vasileios Lampropoulos, Technical Manager of leading tanker company Thenamaris (Greece) who presented Thenamaris’ on-going energy efficiency project it started in 2007 in cooperation with DNV. Initial assessment revealed large savings potential on energy consumers, such as steam systems, cylinder oil consumption, and diesel engine performance. In the same token, savings potential on voyage performance improvements would be substantial. Lampropoulos gave a best-practice example of their on-going pilot study with SEABRAVERY, a 105.000 dwt aframax oil tanker using Marorka’s Maren energy management system. He demonstrated the system’s architecture onboard and the benefits of having an integrated energy management system, providing a comprehensive overview of the vessel’s energy performance.
Mr. Esa Jokioinen, Manager of R&D Services at Deltamarin (Finland) introduced a systematic approach to improving energy efficiency of existing vessels, putting the process into a practical four-step process. The first step is named ´Step zero´ where companies should analyze existing operations, set targets and start the planning process. Next, the ´easy wins´ should be addressed as all shipping companies have the opportunity to make simple operational improvements that do not require a large investment and have pay-back time of less than 2 years. Larger and more complex projects that DELTAMARIN offers include minor hull opening and appendix modifications, propeller optimization, weld seam smoothing, turning waste heat into electricity and others. Finally, Jokioinen discussed energy savings program offered by V.DELTA, a company their co-owned by DELTAMARIN and V.SHIPS.
Dr. Takis Varelas, Projects Management Director of Danaos Corporation (Greece) and Mr. Dimitris Theodosiou, Managing Director of Danaos Management Consultants jointly gave a presentation titled Energy consumption minimization vs. exergy potential maximization. The view of Varelas is that there is overflow of information on how to save energy, but we should be most concerned with putting the energy to use for the core elements in our operation that serve an economic purpose. The term exergy evolves around turning one form of energy into another form of productive energy. Mr. Theodosiou demonstrated a voyage of a vessel that needs to find a new route as a result of bad weather. With technology developed by DANAOS, the optimum route is calculated as going as close as possible to the bad weather without experiencing any significant delays.
Dr. Jon Agust Thorsteinsson, Managing Director of Marorka discussed future trends for energy management and environmental legislation. IMO estimates that under unchanged scenario, emissions from the shipping sector will more than double by 2020 and could increase three-fold by 2050. This, combined with anticipated environmental legislation, is of big concern for the shipping industry which should make a serious commitment to reduce its footprint on the environment. Jon introduced the work of IMO’s greenhouse gas working group which has put together a framework around energy management, including the so-called Ship Efficiency Management Plan (SEMP), a company plan for improved efficiency of ships. In order to meet the need for the industry to measure its own performance, the group is introducing two indexes: Energy Efficiency Operational Index (EEOI) and Energy Efficiency Design Index (EEDI).
Mr. Kristinn Aspelund, Director of Sales and Marketing at Marorka stated the primary objective of energy management as follows: to optimize the use of fuel, that is, to maximize profits and minimize environmental effect by more effective use of fuel. He introduced Marorka Marine Energy Management Cycle, a useful tool in managing the implementation of energy management. This follows a philosophy similar to classical quality and management programs, including several key steps that follow a cycle to ensure continuous improvement. The steps are Commit, Plan, Implement, Evaluate and Act. Finally, Kristinn gave an overview of Marorka’s flagship product Maren.
