Precise Fuel Consumption Measurement on Board Ships.

Innovative metering devices help the Hamburg shipping transport company John T. Essberger in the everyday hunt for unnecessary fuel consumption.
KRAL Flowmeters provide precise SPM measurement values on the Essberger ships Swakop, Zambesi and Selinda.

The ongoing crisis is one of the most difficult that the shipping industry has ever experienced. Financial resources have become more scarce secondary to decreased freight and chartering rates, and high bunker costs are putting additional pressure on companies active in the shipping industry. This is why the John T. Essberger Group (DAL/JTE), a German-African line, has been putting more emphasis on the precise measurement of the fuel as well as the lubricating oil used on its ships. With groundbreaking ship performance monitoring and the use of precise fuel measurement technologies, Essberger is able to offer its charter customers the ultimate in competitiveness and transparency in shipping. These are the best conditions for consolidating business partnerships while successfully enduring the crisis.

The Hamburg shipping company John T. Essberger has invested in a ship performance monitoring (SPM) system from a company called M.A.C. System Solutions of Egestorf, Germany. This system provides for the precise analysis of usage measurement using flowmeters from KRAL, which presents the information in a practical way. In the M.A.C. system the data from shop tests, sea trials and tank tests form the foundation for a basis curve (base line).

Thomas David, head of new building with Essberger, follows a very self-evident logic: shipping companies and charterers have to do business in a way that delivers profit in a difficult market environment. As a result, charterers opt for ships with low fuel consumption, and shipping operators have to offer ships with optimal usage efficiency. The shipping concern sets the consumption for the chartering party in metric tons per day [mt/day] with approximately +5%. The agreement is valid under defined weather conditions, defined load and the two operating points slow steaming and normal operation. The shipyard and the component supplier have to have concrete agreements concerning both fuel consumption and lubrication consumption in terms of new ship construction. All concerned must agree so that the calculated profitability of the ship is later realisable in actual sea service, and so that this profitability can be maintained over the lifetime of the ship.
