Nippon Paint adds XShip to its Hull Condition Monitoring Solution

October 31, 2020
Nippon Paint Marine has enhanced its existing hull condition monitoring software by adding the XShip Performance tool to its established KP Analysis fuel-saving system. While Nippon Paint Marine’s in-house KP Analysis Team’s service has been offered to verify the fuel and power saving of its low-friction LF-Sea antifouling range since 2006, the introduction of the ISO 19030 standard in 2016 has been widely accepted by the industry as a means of verifying the performance of hull coatings. The decision to add the ISO 19030-compliant XShip methodology has already paid dividends, resulting in Singapore-headquartered shipowner Berge Bulk Maritime specifying the low-friction A-LF Sea coating for its fleet of bulk carriers. Bill Phua, Nippon Paint Marine Managing Director, Singapore, said: “Our enhanced hull performance measurement software enables the shipowner to have a continuous evaluation of the interaction between a vessel’s hull and propeller. We can provide more precise data on how the hull coating is affecting speed loss, fuel efficiency, and emissions. “Dependent on the coating applied, ship operators can benefit from significant fuel savings, but these annual savings reduce over time due to hull and propeller fouling. Vessel performance monitoring between two drydock intervals can help maximise the coating efficiency and, as a result, lower fuel consumption and emissions.” The XShip software enhances Nippon Paint Marine’s existing capability to monitor and verify the performance of vessels with a low-friction A-LF Sea coating application, by generating real-time management reports, weather reports, and performance assessments. “A monitoring system compliant with the ISO 19030 standard was a key factor in Berge Bulk Maritime’s decision to apply A-LF Sea hull coating as part of its current drydocking program,” said Nippon Paint Marine Director John Drew. “The additional performance verification delivers further confidence to shipowners that an A-LF Sea application not only reduces a vessel’s impact on the environment but also results in energy and cost efficiencies.” The Singapore-based owner operates a fleet of 78 modern bulk carrier ships of between 34,000dwt and 388,000dwt. Berge Bulk Maritime superintendent Chai Teck Chaw, said: “Based on the performance data provided by its monitoring system we decided to apply Nippon’s A-LF-Sea system to our vessels. The reporting and monitoring of the ship’s hull condition are clear and provides us with insights about hull condition and its effect on energy efficiency.” Bill Phua added: “We are delighted to be working with such a forward-thinking owner. CO2 emissions are a major global concern and as a paint manufacturer, we can help towards reducing a shipowner’s carbon footprint by reducing drag on the underwater hull surfaces. “Together with our advanced hull condition software, the A-LF Sea can help shipowners reduce the amount of high-cost bunker fuels required.” A-LF Sea has been applied to more than 3,000 ships since the product was introduced in 2013.

Creating meaningful reports from reliable data – Changing perspective

September 22, 2020
The adaptation of newer technologies in the marine industry is not so common unless the technology yields significant outcomes. Since the marine industry is now changing its phase to more digitally dependent/enhanced to reduce the operational cost and increase economic growth. The introduction of Data analytics in the vessel performance equation had become a remarkable breakthrough in deciding the parameters that in turn drives the performance overall. Data-driven decision making will secure added profit while optimizing the fleet operation. Data gathered from the vessel is very crucial in performance monitoring and further analysis. Noon data reporting is the traditional way of collecting the vessel data to the shore and sending for accessing the vessel performance measurement. The quality and integrity of the data and in-turn performance measurement have become so important nowadays as the ship owners and managers around the world are becoming quite enthusiastic to yield better results. The performance measurement is carried out in determining Speed loss/ Fuel Saving/ Fuel Loss of the vessel which are driven by parameters like Wind, Weather, Sea state, Trim, Draft, etc. The real question arises how this quantifiable data is captured and how reliable is the output? Consider Fuel Consumption, for example, Trim, Draft, and environmental parameters are directly driving the high and low state of fuel consumption. The data is gathered on daily basis for the noon report and the average of this report decides the performance graph. The noon report data is significant as the most commonly used reporting tool. However, the technology in the marine sector is becoming advanced so that the data gathering and sending for analysis are far replaced without much human interference. Automated frequent data collected using several sensors equipped onboard is one of these advancements. The data thus gathered is delivered to the shore where it is processed. In the noon report, the percentage of error occurrence is quite high as the whole process is manually maneuverer. However, the dependency of noon reports still predominantly exists and Even in the current scenarios, this traditional approach is widely popular. Automated frequent data allows a more detailed and precise analysis than the noon reports due to the reduction of human error by minimizing the manual inputs. When analyzing parameters like the weather which has high uncertainty relying completely on the noon report will affect the quality of performance measurement. Automated frequent data will increase the reliability in such scenarios. The availability of high-frequency data allows for better analysis and more accuracy. Let’s interpret with numbers, If we take the 3 months vessel data for performance measurement from noon report and automated frequent data it would be evident that after deducting the errors and outlier only 45 -50 good quality data points will be available from noon report. Whereas automated frequent data that fetch the data continuously in every 15minutes will provide around 5000 good quality data for performance analysis. We XShip is completely equipped to give quality results. XShip is now an industry leader in processing and

Saving Fuel by Trim Optimisation

July 22, 2020
Vessel type: 36000 DWT Bulk carrier Scope of assessment: To find out the Power & Fuel saving of the bulk carrier vessel by following the optimum trim condition and validate the CFD method of optimum trim. Result: The vessel operated under the optimum trim condition for 4 months. The vessel had 5.9% fuel savings. This translates to a significant annual savings of 323 tonnes of fuel and 162K US$. Background: Effect of trim  Ship trim optimization simply advocates selecting the trim condition for minimum resistance at the given draft (displacement) and speed. The resistance through water decides the power and the fuel consumed. Hence, less resistance implies lesser emission and more economical operation by fuel savings. The power required varies with trim, draft, and speed of a ship. Determining the most efficient trim from analyzing all these combinations through experimentation is impractical whereas thorough computational fluid dynamics (CFD) simulation, can easily be obtained. Ship management can further focus on creating awareness in the crew about the economic and ecological value of the fuel savings and emission reduction, through operation at optimum trim. The information can then be used to adjust the trim of the vessel. If extra ballast is required to re-trim the vessel, this can be considered to find the new optimum trim including the ballast weight. Optimum trim: Various trim cases were considered for finding the condition in which power consumption could be minimized. This study was carried out for numerous cases by varying speed and draft ranges. A significant decrease of the ship resistance for the analysed models was achieved and validated by the comparison with the well-known sea-trial and model test result database. After considering all factors, where the power consumption is minimal is termed as the optimum trim. Power trim table for scantling and ballast draft at various draft shown above the red marked point shows the lowest power corresponding to the various speed Savings Potential: Optimum trim for the vessel may be different from the current operation trim of the vessel. Vessels can attain the optimum trim in two ways – by keeping the same displacement without extra ballast or by adding ballast. In the former case, there is a fuel-saving which the ship can achieve by just re-arranging the ballast or cargo. In the latter case, a different saving is achieved by adding extra ballast. In any case, it is evident that the ship can attain some fuel savings by changing the trim compared to the current operating conditions which is called saving potential. Each trim different from the current operating trim has some saving potential which may not be optimum but maybe the best achievable trim. The saving potential is calculated considering the improvement that can be made from the current operating trim. Methodology: Optimum trim of the subject vessel is 1 m by aft for laden conditions. The ideal way to find the fuel savings is to compare the fuel consumption of the vessel during the period of optimum trim and non-optimum trim. To avoid the effect of displacement in fuel consumption, we have taken a constant displacement for comparison. So comparing the fuel consumption between both the voyages, we can see the savings for keeping the optimum trim. The vessel has reported wrong power values for some period, hence brake power, converted from the fuel using the SFOC curve is considered for the analysis. Since we are interested in the change

Why Marine electronic logbook is essential?

April 30, 2020
International Maritime regulation requires all ships to carry a deck and engine logbook to record the performance of the ship, her machinery, boilers, and other daily events including ship’s position, speed, course, weather conditions, fuel consumption, tank soundings, machinery operating pressures and temperatures, and any incidents which may appear to be of importance to the safety of life at sea, prevention of pollution to the marine environment, etc. It maintains a record of navigation and engineering activities and incidents which must contain sufficient details to restore a complete record of the voyage. Methods of the recording should be permanent and may be handwritten, electronically, or mechanical. Why E-Logbook is essential? As the manual logbook entry is not only a tedious and time-consuming job but also an important routine activity that has no space for carelessness. Moreover maintaining such paper records is very difficult and risky as a small accident or carelessness can wipe out the entire history of the engine room. As an important document, it should be free of errors. It is for these reasons that there is a strong need to replace paper logbooks with an electronic logbook and one of our clients had approached us to offer a suitable solution for their container fleet.

Practical approach for ISO 19030 analysis

April 6, 2020
Vessel type: Bulk carrier Scope of assessment: Counter verification of the claims from various paint suppliers and suggesting the best grade and vendor. Result: A suitable vendor was suggested to the client for their paint requirement. The client was also notified about the issue in the data quality of their noon report. Recommendations were provided for them to improve data quality. Background A leading ship management company recently consulted us for advice on choosing the right marine paint for their vessel which is about to dry dock in 2020. Like any other shipowner in the maritime industry, they were also confused by the promises offered by various paint suppliers regarding the potential fuel savings. They were confused on choosing different grades (Low friction or Normal) and suppliers as the cost v/s benefit scenario was not clear for them. They were not confident with the reliability and accuracy of the results as it was based on the noon data reports. Theoretical comparison is easy but when it comes to the practical scenario it is difficult to validate the results. In the view of the above, we suggested they categories the data of different paints used in past. The actual gain was not available with them. So we had to depend on the theoretical data. We decided to conduct an ISO 19030 Analysis with the data available. ISO 19030 – Speed loss analysis Even though ISO speed loss analysis is preferred for ADA data, it can also be used for noon data but with correct exemptions followed. The vessel didn’t have monitoring devices and hence ISO alternative methods and data filters have to be implemented carefully. After filtering of data, we got the result with maximum accuracy. Fuel savings from various paints were provided to the client. They used these results to verify the vendor promise and chose the right vendor for their vessel. With this study, they also understood the issues they are facing with the data quality in their noon reports and have started to take corrective measures with our consultancy. Conclusion Shipowners are always facing difficulty in counter verifying the results submitted by paint suppliers. Even though paint suppliers use ISO methods it is an industrial practice followed by the paint suppliers to use the cubic relation between power and velocity. It is the theoretically correct method, but in reality it varies. So we recommend and follows the usage of actual scenario in our ISO analysis which will give quantifiable results

How Vessel Data Management System Simplifies Operations

March 6, 2020

Engineering study for installation of additional sea chest

November 6, 2019
Vessel: 104,183 DWT Bulk carrier Background: As the vessel is planned to undertake scrubber installation, there is a requirement of additional sea chest fabrication for the intakes and outlets of the scrubber. The client engaged us in an engineering study and design solutions to finalize the sea chest position and piping onboard. Scope of Assessment: Engineering study to identify the position of additional sea chest and preparation of all necessary drawings in the most cost-effective way. How we achieved? As the vessel, 3D scanned model was not available. Usually, in such cases, designers undertake 3D scanning and prepare a 3D model to prepare the engineering drawings. Our vast experience and expertise made us analyse the exiting structural drawings, double bottom drawings, and engine room construction drawings to propose a suitable location for the additional sea chest. Once the location was finalized we conducted a feasibility study onboard the vessel to finalize the same. Sea chest drawings, hull penetration, side shell cutting drawings, piping diagrams, and other production drawings were prepared and made approved by DNV-class. As the 3D scanning and modeling were not considered for this engineering study there was a huge advantage in savings for the client. Conclusion: At a very low cost incurred client could complete the engineering study and drawings prepared for the additional sea chest installation.
