High fuel prices and stricter regulations are increasingly determining the operating costs of ships. KEM offers field-tested and proven solutions for the maritime industry based on years of experience in flow measurement technology.

Working closely with our customers, we help save costs and meet legal environmental requirements by optimizing ship operations.

Our measurement technology ensures that processes such as bunkering and consumption measurement are optimized. For example, by accurately measuring and monitoring fuel consumption on a daily basis, it is possible to sustainably reduce fuel consumption.

With our expertise in automation and instrumentation processes, we can provide the best solution for your measurement needs from the KEM product range.

The combination of high-quality materials, specific designs and geometries, and the use of different measurement principles allows for a precisely fitting range of flow meters for typical applications in the marine industry.

With decades of experience in automation and instrumentation, we are able to offer optimal solutions from the KEM product range.

Coriolis measurement and performance monitoring in real time

NSB GROUP has developed tools for real-time data collection to improve the measurement of fuel consumption. Around 6 million containers are shipped by sea daily worldwide. As a leading provider of tonnage in the container segment, the NSB Group has a substantial share of this market with its vessels. With capacities ranging between 1,000 and 11,000 TEU, NSB reaches a total carrying capacity of more than 3.5 million tdw and a total TEU capacity of about 325,000 TEU. Since 2011, NSB Group has also managed tankers and offshore jack-up vessels.

Thanks to the know-how of our nautical and technical superintendents, all with years of experience on board and ashore, the NSB Group makes the best use of the German maritime location. Thus, customers can rely on its reliability, efficiency and innovative strength. It is also important for NSB to combine economic success and sustainability.

NSB uses the TRICOR Coriolis mass flow meter (TCM) from KEM Küppers. In the past, when fuel was relatively cheap, ships operated at full capacity and were moving quickly. Existing measurement methods for determining fuel consumption were adequate. However, because of inaccuracies in the calculations, converting volumetric flow to mass flow, proper management of the ship's fuel supply was difficult. Moreover, gauges were designed to match the full capabilities of the main engine (ME) and auxiliary engine (AUX). Today, the old systems have reached their limits. Due to slow steaming, fluctuations in fuel prices and increasing environmental and efficiency requirements, efficient ship management is no longer possible. At the same time, charterers and owners are demanding cost control and transparency.

Solution

After extensive research into what is available on the market, NSB chose the TRICOR Coriolis massflowmeter. The high flexibility of the system output, appropriate to the performance data module, and easy commissioning were additional criteria. NSB also paid particular attention to system reliability.

To improve the accuracy of fuel measurement, volumetric measuring instruments are gradually being replaced by modern mass flow meters based on the Coriolis principle. These meters allow direct mass balance of consumption and can provide sustainably assessable data due to high accuracy and reproducibility. This gives NSB an above-average ability to meet the transparency requirements on the cost structure of ships combined with the accuracy of fuel invoicing.

All ship-relevant operating data are communicated via MODBUS to the performance monitor co-developed by NSB. This modular system consists of a "reporting module" and a "performance module." The core of the on-board system is a small server unit containing the program, the reporting module and the database. The server is integrated into the ship's computer network. The transmitted data are stored in the ship's database, the contents of which are automatically sent ashore several times a day. Thus, the shipping company always receives the information "live.

Importantly, the "performance module" automatically collects all relevant operating data using data collectors installed on the bridge and in the machine control room. The collected data are stored in the ship's database. In this way, for example, all data on fuel consumption, engine performance and speeds are measured "online" and transmitted with the regular data transmission. The modular design of the measurement system allows continuous expansion to adapt to increasing demand and needs.

This globally distributed system from NSB Marine Solutions digitally prepares the collected data in such a way that it provides NSB management as well as charterers, ship owners and other users with valid performance indicators that serve as the basis for further optimization of the vessel. operation. The TRICOR Coriolis flowmeter and performance monitoring system form a comprehensive management solution.
