Managing environmental impact and energy use
Although not yet covered by agreements such as the Kyoto protocol, shipping and its environmental performance is increasingly coming under the spotlight. For shipping lines, environmental concerns are broad. Some of the major ones are: – Improving fuel use – Implementing energy saving technology – Identifying suitable energy using applications for improvement – Energy monitoring
Improving fuel use Running auxiliary engines in port to create on-board power raises fuel costs and creates emissions that affect health and the environment for passengers, crew, dock workers and local residents. A solution to this is a shore-to-ship electric power supply, which involves a ship shutting down its engines while berthed and plugging into an onshore power source. The power load is seamlessly transferred to the shore side power supply with no disruption to on-board services. A shore-to-ship electric power supply can help eliminate pollution problems as well as noise and vibration from ships in port. ABB offers a complete, seamlessly integrated shore-to-ship power solution for safe and reliable power transfer from the public electric power grid to the ship while in port. This complies with international standards laid out by the relevant professional bodies. Implementing energy saving technology Among the large energy consumers on board vessels are seawater cooling pumps, chilled water pumps and engine

room ventilation fans. These applications are often overdimensioned to handle the most extreme conditions. In addition they typically operate at full capacity even when demand is not high. Any flow control is often through mechanical devices such as bypass valves and dampers which are inefficient in that they effectively waste energy. A more energy efficient option is the variable-speed drive. Drives can reduce energy use by 50 percent with payback, from fuel savings alone, in less than one year. Identifying applications for improvement To help the shipping industry find the applications that can most benefit from energy-saving technologies, ABB has devised a marine energy appraisal service that aims to identify the motor-driven applications that can benefit from the use of variable-speed drives, with payback often under two years. An on-board energy appraisal survey results in a report that shows the comparison between power consumption and demand. Typical findings may show that the: – Vessel has been designed for worst case climate condition – Motors of fans and pumps run only at fixed speed – The current system may be wasting up to 70% of energy A cost proposal for implementing improvements is presented showing investment costs, payback and environmental improvements. Energy monitoring Effective energy monitoring on board ships is a major step towards more efficient use of this expensive resource. To hope achieve this, ABB has developed its energy monitoring and management (EMMA) tool. It is highly developed software running on ordinary PCs on-board and ashore and optimises energy-related processes, practices and decisions, from engine room to the board room.
Solution: – Ship to shore power supplies – Energy saving technology such as variable speed drives – Energy monitoring tools Benefits: – Cut energy costs – Reduce carbon emissions to comply with possible regulations – Cut vibration, noise and pollution at dockside

ABB Service - Marine: Energy efficiency factfile/April 2012
EMMA has been developed specifically for marine companies to operate a ship, several ships or a whole fleet with best possible energy efficiency and environmental responsibility. It puts energy on the agenda throughout the company and makes it possible to optimise energy-related processes, practices and decisions, all the way from the engine room to the board room.
