Parker Kittiwake LinerSCAN Brochure

  1. 1. A new era in asset protectionLinerSCANThe worlds first real time liner alarmEarly warning system formain engine damage
  2. 2. The world’s first real-time alarm system for engine liner wear. LinerSCAN marksa new era in asset protection, providing early warning against critical enginedamage whilst providing the information needed to save on lube oil costs.Kittiwake’s LinerScan system is designed to remove theuncertainty on cylinder damage resulting from low fuelquality, slow steaming, low sulphur levels, lower oilfeed rates and cylinder oil formulation changes.Financial savingsOptimize feed ratesHighlight problems with low sulphur fuelAid in preventative maintenanceIncrease lifetime of your cylinder linersPrevent engine damage and down timeLinerSCAN provides highly accurate feedback about the wearcondition in your engine. Trials have shown that LinerSCANhighlights the first signs of damage earlier than other systemsand enables safe reduction of lubricant feed rate. If the wearrate increases during normal conditions the system will generatean alarm which, when connected to the ships alarm, providesinstant feedback allowing for immediate action. This allows forpreventative maintenance during the ships passage to the nextport, or even a route change. LinerSCAN is a fully automatedsystem and will help save money by optimizing the lubricantfeed rate, reducing your maintenance loads and by helping youprevent unnecessary engine damage.Why it is becoming increasingly important to monitor wear?System BenefitsProvides accurate and actionable data on yourengine wear levelsEnables safe reduction of cylinder oil feed ratesDramatically reduce engine damage by spottingthe first signs of scuffing or piston ring damageHighlights the issues caused by fuel problemsAllows an informed running-in processRuns fully automated – with no humaninterferenceProvides savings immediately after installationSimple installation for both new and retrofit Highly capable communications enable the system to link with ships management systems. Bespoke user-friendly software interface for data evaluation onboard or in the office. LinerSCAN takes the usage of oil analysis data a stage further than is possible with laboratory or test kit results Reliable and robust – Once installed, the workings of it can be ignored Compact units require little space per cylinder LinerSCAN utilises patented ANALEX technology from KittiwakeLinerSCAN Features
  3. 3. An ‘Overview’ tab shows all readings, an event log andallows exporting of the data and log information which canbe sent to the head office for further investigation if needed.Using the ‘Configuration’ tab you can set individual alarmsfor each liner to allow for informed running in processes onindividual liners.The LinerSCAN system can be connected to your shipsalarm system via a 4 - 20 mA connection or the use oftrip amplifiers which communicate alarms for liner wear,blockages, and other system alarms.An extremely informative graphing tool allows for in depthdata evaluation on-board and in the office. Simple on-screen options enable the viewer to alter the scaling ofrunning hours and ppm values for detailed and personalisedinterpretation.LinerSCAN software provides an informed view of singleor multiple liners and (if connected to the system) plots ofessential engine information such as rpm, load, sulphur orfeed rate can also be included.The data provided then enables the user to react to changesand adjust the feed rate according to the actual liner / engineneeds and requirements based on real time data.An office based version of this software, called LinerSCANView, is available for easy evaluation of data from remote orshore based locations. Data is easily exported from onboardand then imported into the LinerSCAN view software.Measurement PrincipleLinerSCAN measures the amount of iron in cylinder lubricant by a method known as magnetometry, where a sample is testedin a magnetic field. Utilising a novel shielding method the system exploits a fundamental physical effect: namely the change ofinductance due to the presence of a magnetic material.Analysing the scavenging air space drain oil from each cylinder for iron (Fe) has been proven to give the operators an indicationof relative changes of cylinder liner wear. At very early stages, the sensors reported the onset of severe wear and other engineproblems such as cat fines in the fuel.The system will also highlight periods where the engine is subjected to increased stress levels and indicate changes in iron levelscaused by imbedding processes and increases in wear caused by routine inspection.Simple Interpretation and Communications with Ships Automation System LinerSCAN software enables you to continually monitor critical cylinder information on screen using a bespoke graphical user interface.A ‘Dashboard’ highlights all critical information at a glance with colour coded liner symbols showing wear levels and current readings.Alarms are displayed on the screen for system alerts and engine / air status and are also communicated (optional) to the alarm systemof your ships automation system.This chart shows the ability of LinerSCAN to detectand trend the amount of iron particles in thecylinder oil in real time.Feed rate was reduced by 10% on cylinders 4 and5 at 59961 engine hours. Wear levels increased fora short time and were monitored before returningto normal levels.This process was then repeated across the other5 cylinders providing an overall 10% decrease incylinder oil usage.
  4. 4. The following work is required prior to commissioning:Welding of bosses to scrape down oil pipe with valvesfor oil in and out.Mounting of the LinerSCAN boxes.Install pipe for compressed air along the engine.Run cables from Engine to ECRWindows PCProvide connection to engine control or ship alarmsystemSimple Installation and CommissioningLinerSCAN is very simple to install on new buildings andas a retrofit to existing ships. Previous installations haveproven that the system can be installed by the crew althoughKittiwake also provides a commissioning service usingexperienced engineers. Kittiwake can also assist with dataevaluation if requested.MAN B&W Diesel SupportedMAN / B&W Diesel: “...Analysing the scavengingair space drain for iron (Fe) has been proven to givean indication of cylinder liner wear. ...

Price and details available on request.Contact Kittiwake for more information about your specific engine type and application.ECON Waterin Oil Test KitOrdering InformationProduct Code DescriptionSince 1993 Kittiwake has provided the industry withinnovative ship-based solutions to help onboardengineers monitor and test fuel, lubricant and waterconditions to achieve better operational performance.Operating from 6 international offices and through anetwork of agents and distributors, our innovative approachto solving real life problems has made us a favouredsupplier to many large organisations worldwide includinginternational navies, oil majors, offshore platform operatorsand thousands of other industrial users.The Kittiwake critical fluid test kits, developed usingpatented technology, have pioneered machinery conditionmonitoring at sea, enabling engineers to check fueland lubricant condition and take remedial action whereneccessary at short notice.In the past, this kind of precision analysis was confined toshore-based laboratories. Detailed testing of fluids on anyvessel required samples to be packaged and then sent awaywith results returned typically after a period of days, weeksor even months. Kittiwake solutions for sampling andanalysis provide instant results when your ship needs themthe most.Visit for more information aboutKittiwake and the LinerSCAN system.About KittiwakeThe use of LinerSCAN is not solely limited tothe prevention of engine damage. Constantreal-time monitoring gives engineers a vitaltool in maintaining and optimizing cylinderoil feed rates and helps reduce many otherassociated costs.The chart to the right shows that the cost ofcylinder oil and the liner itself are the biggestcost factors when operating a main engine.Existing installations have proved that significantcost savings can be achieved with return oninvestment achieved in less than a year in somecases.Visit for further informationas well as a reference list.Rapid Return on investmentRef: Dev.
