Why Marine electronic logbook is essential?

May 6, 2020
International Maritime regulation requires all ships to carry a deck and engine log book to record 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 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 recording should be permanent and may be handwritten, electronically or mechanical. Why E Logbook is essential? As the manual log book entry is not only tedious and time consuming job but also an important routine activity which 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 engine room.

Practical approach for ISO 19030 analysis

May 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. Client was also notified about the issue in the data quality of their noon report. Recommendations were provided for them to improve the data quality. Background A leading ship management company recently consulted us for an advise on choosing the right marine paint for their vessel which is about to dry dock in 2020. Like any other ship owners in 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 reliability and accuracy of the results as it was based on the noon data reports. Theoretical comparison is easy but when it comes to practical scenario it is difficult to validate the results. In the view of above, we suggested them to categories the data of different paints used in past. Actual gain was not available with them. So we had to depend on the theoretical data. We decided to conduct a 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 used for noon data but with correct exemptions followed. The vessel didn’t had monitoring devices and hence ISO alternative methods and data filters has to be implemented carefully. After mass filtering of data we got result with maximum accuracy. Fuel savings from various paints were provided to client. They used these results to verify the vendor promise and chose a 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 Ship owners 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 theoretically correct method, but on reality it varies. So we recommend and follows the usage of actual scenario in our ISO analysis which will give quantifiable results

BWTS Retrofit – 39,000 DWT Bulk Carrier

May 6, 2020
Vessel : 39,000 DWT Bulk carrier Background : Installing a ballast water treatment system on an existing vessel is typically complicated than a newbuild. Ballast water treatment system retrofit is not simple installation of new equipment, it involves feasibility study and detailed engineering. XShip was contracted to undertake the feasibility study and detailed engineering design for the installation of a BWT system in 39,000 DWT Bulk Carrier. Scope of Assessment : Feasibility study to identify the suitable location & preparation of all the necessary drawings and plans for class approval and final installation of Ballast water treatment system How we achieved? To prepare for installation, we conducted an onboard survey with 3D scanning partner to identify the best possible location for the equipment and to gather information on ballasting operations. After processing the information gathered, a 3D model was developed. It helped to evaluate the suggested installation and determine how the piping should be routed and the need for additional supporting structures of the installation. Once the owner accepted the location, we entered into detailed engineering phase. We used the 3D scan to make the production drawings, piping design drawings and electrical design drawings which included the pipe routing, changes in existing piping system, equipment lowering and access plan, electrical line plans etc.. We submitted all the necessary documents to classification society for the approval and liaison with classification society for the approval of the drawings We also have the capability and experience to undertake the supervision and project management for the installation of Ballast water treatment systems onboard the vessels.  Conclusion : XShip provides services to ship owners all around the world, we can undertake all or part of the technical aspects of the retrofit job from concept and basic design to detail design and supervision

May 6, 2020
Vessel : 104183 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 scrubber. Client engaged us for 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 to analyse the exiting structural drawings, double bottom drawings, engine room construction drawing etc to propose the suitable location for the additional seachest. 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-GLclass. As the 3D scanning and modeling was 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 preparation for the additional sea chest installation.

“ XSHIP FLEET LIVE ” COMPLETE SOLUTION FOR FLEET MANAGEMENT

May 6, 2020
Background It is estimated to have more than100 Ferry operators across the country. We find it bit odd that despite of high experience in operating large number of ferries for long years, efficient fuel monitoring,vessel tracking and advanced online ticketing is still considered to be a technology or solution which exist miles apart. Current Scenario Ferry owners and operators have to rely on information provided by on-board personnel or crew. This information maybe subjected to human errors and manipulations and cannot to be considered reliable.Result is the huge loss in many ways, viz high fuel usage, improper maintenance, unorganized trip schedules etc. XShip Fleet Live Fleet Live is more than a solution, its a platform where all the essential fleet management solutions are arranged and kept customized. It is updated to fulfill the very needs of its customers“Customization” its a big word in the software services industry and XShip very well knows the significance of delivering completely customizable solutions and we believe this as our quality rather than uniqueness.We designed Fleet Live following the same path and procedures we do to serve our shipping industry clients and developed to the perfection to meet the exact requirements or needs and deliver it efficiently. Features in XShip Fleet Live Fleet Live enable the vessel operators and owners to track and locate the boats real-time. It provides accurate locations of vessels and vessel’s speed at periodic time intervals. A vessel tracking system will play a very important role by bringing about long range connectivity. Vessel mishaps can be easily tracked and losses can be minimized by initiating fast – rescue operations. System also improves the operating efficiency as the vessel owners and operators can track their fuel consumption, engine health and plan the vessel maintenance. The system is suitable for electric driven or conventional engine driven boats. Route feasibility reports can be generated with less efforts using this software. XShip Fleet Live is also equipped with features like live weather and voyage planning which will reduce the time and effort of vessel operators. How XShip Fleet Live works ? The on-board units measure the operational parameters of the boats(state of the switches, fuel consumption, engine parameters,etc.), and its position (aided by GPS-based location), and they store the data given by the driver (the name of the actual activity, etc.). These parameters are sent to a central server at the actualization of previously defined events (alarm-signal, sudden decrease in fuel level,etc.) and in previously defined periods of time. On-board units communicate with the central server through mobile systems. The incoming data are evaluated and stored in a relational database. If necessary the central server can send an alarm to a given e-mail address or even a mobile phone. In this structure the communication from the server towards the vehicle is plausible as well. Aided by this the incoming data packages can be confirmed, a text message can be sent to the driver and the parameters of the on-board unit can be set. Boats are

RESISTANCE CALCULATIONS FOR RORO BARGE USING CFD

May 6, 2020
BACKGROUND Design of an Irclass RoRo Barge for the Indian Defense was one of the prestigious project which we undertook. One o of the challenging task in this project was to understand the resistance and powering for the vessel. As an experienced design house we know that correct powering prediction is the first step in a successful vessel design.Hence we used CFD analysis for resistance calculations barge and compared the results with the experimental model tests. Details of one of the iterations were as follows. ANALYSIS-PROCESS The 3D model of the barge was prepared and imported into CFD software. 3D domain was created around the hull form. The complete domain was meshed, with are fined mesh around the hull for better resolution of boundary layer flow. The boundary layer thickness and number of layers were adjusted to account for turbulent flow around the barge hull.Multi-phase analysis was done in this study by using the interface- capturing approach, which solves the RANSE equations on a predetermined grid that covers the entire domain, and the Volume of Fluid (VOF) method, to simulate the free surface flow for the barge. For turbulence modeling, the Shear Stress Transport K–ω (SSTK-ω) model was used for the numerical solution. The boundary condition specified was similar to that of the experimental setup. The motion of the free surface was governed by the gravitational acceleration. The CFD domain was thus modeled as open channel flow, consistent with the experimental setup. At the inlet, a uniform flow was specified. The hydrostatic pressure at the outlet was calculated assuming an undisturbed free surface. Smooth walls with a no slip condition were assumed for the top, floor and the side wall. Finally a multi phase transient solution was carried out to calculate the resistance on the barge. The result plots show the wave pattern ,water elevation, velocity stream lines, velocity vectors and pressure on the hull. MODEL TEST Model test was conducted to validate the CFD results: Vessel had a length of 25 meter, a depth of 7 meter and have a design speed of 9 knots. To suit the model testing facility a scaled down model(1:9) was considered for hydrodynamic calculations. Model was ballasted to represent the loaded condition. Results were obtained by extrapolation on the basis of ITTC78 prediction method using froudes law of scaling. RESULTS The results of CFD analysis was a good match with the experimental study conducted later. The CFD method, in comparison with the model test, has great advantages, such as lower costs, reduced time, accessibility and more visible details in results e.g. pressure and velocity contours, vectors and gradients. It also allows designers to calculate the hull resistance and investigate the flow around the hull without having to do a towing tank test.

UNDER PERFORMANCE CLAIM VERIFICATION

May 6, 2020
Vessel : Bulk Carrier Scope of assessment : Evaluate the vessel performance in view of the under performance claim for the vessel. The vessel underwent a propeller modification to increase the light running margin. Conclusion : On evaluating the reported data after the propeller modification, It was evident that the light running margin has increased and the under performance claim was true. The analysis showed that there was a reporting error in the Power, which was later confirmed by the vessel. How XShip solved the problem ? Data before and after the propeller retrofit was evaluated to check the running margin. Results showed that the light running margin for the vessels has increased from1% to 6% on an average. Under performance claim was verified through the Charter Party Analysis tool of XShip which showed that the claim was right. We analyzed the vessel performance before and after the propeller modification. It was observed that there was no fuel loss due to the propeller modification in running condition, and there was no gain either. As the propeller modification was done to increase LRM and to ensure reserve rpm during maneuvering, the actual purpose was found served and this result was satisfactory. But in contrast to the Fuel analysis result,the vessel was showing an 8% increase in the required power after the modification,which implied that the modification was a loss in terms of power. As XShip gives the result based on the underlying relationship between Fuel and Power with the vessel operating conditions and environmental conditions, The gain/loss in power and fuel must be analogous. The large deviation in power and fuel results led to a detailed investigation and it was noticed that the power reported was high after the modification. The XShip results and conclusion prompted the technical managers to inquire with the vessel. The ship staff agreed that they were reporting a higher ME power to show the charterer that engine was operating at higher load as they were not making CP speed.

PBCF FUEL GAIN ANALYSIS FOR BULK CARRIER

May 6, 2020
Vessel : Bulk Carrier Scope of assessment : Study was conducted to understand the fuel savings from PBCF installation. PBCFs are an energy saving device (ESD) that can enhance propeller efficiency, thus requiring less power to propel the vessel forward at a certain speed. Conclusion : It was identified that the vessel has gained4.8% on Fuel oil consumption after the PBCF installation. From our analysis with the reported data it was clear that no other dry dock effects added to this gain Merits of XShip performance : Normally fuel consumption calculation and prediction is difficult as it is dependent on various vessel operational parameters. Major problem with the assessment of the vessel performance is determining a baseline within the wide operating ranges. This makes both assessment and predictability of ship performance a complex phenomenon. In general the assessment models are based on the model test results or sea trial results which doesn’t consider the actual degradation of vessels. XShip performance creates the bench mark considering the dependency of various operational parameters and weather in FO consumption and power requirement. Hence XShip performance is most reliable in * Identifying the ROI from other dry dock interventions * Understanding the fuel gain from PBCF installations * Predicting the fuel consumption for the vessels in future How XShip performance calculated the PBCF Gain? The reported data before and after the PBCF modification was analyzed using the XShip Performance tool. The model for the bulk carrier was created based on her actual consumption and its dependent variables. The performance of the vessel is compared based the model for post and pre intervention periods. It was found that there was a gain of 4.8% in Fuel consumption with this modification. The gain then was converted to the cost of the fuel for a specific period to know the return on Investment. The analysis was helpful in understanding the payback period of the modification. And the ship management was able to take decision on this kind of investment for the sister vessels.

XShip allows the users to plan and decide the key parameters for tracking and the tool can be customized based on these requirements.Users can generate reliable monthly reports in PDF formats. How XShip identified the error in reporting ? We have been analyzing the live reported data for client over a period of time and it was found that there is a mismatch in the reported FO consumption and ROB against the bunker data.We reported the issue to vessel owners and in further investigation and communication with vessel crew we identified that error in the FO report was due to fuel flow meters. They rectified the calibration issue associated with the fuel flow meters and corrected the reporting. Our study helped the owners to identify and rectify the issues in reporting that would have eventually resulted in wrong calculations of fuel consumption which inturn affects the operational budgets and error in MRV reporting
