Solutions for the future

We are constantly striving to realize and enhance our business idea “to help customers optimize the running of their engines in order to save time and money while keeping the environment in mind”.

We represent a brand that design, develop, manufacture and market their equipment under three strong brands; Chris-Marine®, Obel-P® and LEMAG® Via Safetechnical Supply Co.L.L.C in the entire Middle East region

We offer six portfolios to our customers:

1. Monitoring

The importance of regular monitoring of diesel and gas engines

To ensure reliable engine performance and determine the optimum time for overhaul, regular monitoring of diesel and gas engines is necessary. Monitoring helps to determine when it is time for maintenance and what type of maintenance needs to be done.

Chris-Marine’s portfolio of Monitoring equipment can help you save costs by identifying potential problems before they occur.

The monitoring portfolio includes instruments to:

• measure surface roughness, liner diameter and coating thickness
• take pictures of the liner to visualize potential wear and damage
• analyze shaft power efficiency
• measure cylinder pressure

In addition, the portfolio contains various precision instruments like calibrators, gauges, and a combustion chamber tester.

Chris-Marine’s cylinder condition monitoring portfolio

for 2-stroke engines

Chris-Marine’s cylinder condition monitoring portfolio facilitates the collection of cylinder liner data and piston ring data. All tools can be used without removing the cylinder cover.

Liner Diameter Measuring Instrument (LDM)

LDM measures cylinder liner wear/remaining lifetime, ovality and clover leafing.

Liner time scale: ~1000 Rh. Measurement time: ~1 h/liner.

Coating Thickness Measurement Tool (CTM)

The Coating Thickness Measurement Tool measures the wear rate/ remaining life time for coated piston rings. Liner time scale: ~1000 Rh.

Measurement time: ~15 mins /liner.

Liner Condition Camera (LCC)

Chris-Marine’s Liner Condition Camera documents the condition of cylinder liner surface, exhaust valve, piston rings and piston crown.

Liner time scale: ~100 Rh. Measurement time: ~15 mins /liner.

Replica Analysis & Microscopy

Takes an imprint of the liner for analysis with microscope in Chris-Marine’s laboratory.

Liner time scale: ~100 Rh. Measurement time: ~15 mins /liner.

Chris-Marine’s cylinder condition monitoring reporting service

We know that time is limited for the crew members operating today’s vessels. This is why we have made a great effort in developing user-friendly tools that make data collection straight-forward. However,  interpreting the data can be more difficult. Chris-Marine has therefore

introduced a cost-effective reporting service that allows customers to collect data on their own and send it to Chris-Marine for processing. Chris-Marine reverts with a report summarizing the findings and comparing the results to other engines of similar type.

A report can include:

• Cylinder liner wear, life expectancy and clover data collected with the LDM, with recommended cylinder maintenance actions based on findings.
• Cylinder liner and piston ring pictures taken with the LCC and analysis of the cylinder condition (under-lubricated / over-lubricated / critical).
• Piston ring wear and life expectancy from data collected with the CTM.
• Cylinder condition and cat fine analysis though microscopic images from

replica imprints collected through scavenge air port. This method is especially useful when changing from high-S fuel oil to low-S fuel oil after 2020.

2. Cleaning

Efficient engine parts cleaning

Efficient and careful engine parts cleaning and cleaning fuel system is important for the performance of any engine. Chris-Marine supplies a wide range of cleaning systems to facilitate the cleaning process for maintenance crews onboard ships, in power plants and at workshops. We offer two different cleaning methods: ultrasonic cleaning and spray cleaning:

Ultrasonic cleaning fuel system

The ultrasonic cleaning fuel systems have transducers generating ultrasound waves. The waves vibrate the cleaning fluid at very high velocity, thereby creating a superior cavitation process. Inside the stainless-steel cleaning tank millions of tiny bubbles implode within the cleaning solution and penetrate every orifice of the item being cleaned, removing various contaminants.

Chris-Marine’s ultrasonic cleaning range covers the cleaning of engine parts like valve spindles, fuel injectors, filters, intercoolers, pistons, heat exchangers and cylinder heads.

Spray cleaning

Our spray cleaning fuel system provides excellent cleaning results thanks to a smart design used together with heat, high spray pressures and liquid flow rates achieved by the built-in pump. The spray system rotates around a fixed load giving a perfect cleaning result together with a very easy loading- and unloading system.

SWM, the Chris-Marie spray washing machine efficiently handles cleaning of small and medium sized engine components such as pistons, piston rings, valve spindles, fuel injectors, cylinder heads, intercoolers, and heat exchangers.

Cleaning chemicals

To get the very best cleaning results, appropriate cleaning chemicals should be used. Chris-Marine offers types of cleaning chemicals to suit different cleaning needs; Ultra Rinse Engine, Ultra Rinse Intercooler and Ultra Rinse Descale.

Ultra Rinse Engine

Ultra Rinse Engine is a high alkaline cleaning chemical suitable for  challenging cleaning tasks. It is ideal for cleaning steel, stainless steel and cast-iron components that have been exposed to heavy fuel oil. It efficiently removes fuel, coke, soot and paint.

Ultra Rinse Intercooler

Ultra Rinse Intercooler is a high alkaline cleaning chemical suitable for cleaning of metals like aluminum, titanium, brass and copper. This makes it particularly efficient for cleaning of intercoolers and turbo parts.

Ultra Rinse Descale

Ultra Rinse Descale is an acidic liquid concentrate based on highly efficient surfactants and inhibitors. This cleaning chemical is often used to remove lime scale, iron deposits, carbon deposits and oil deposits from engine parts.

3. Grinding & Machining

Chris-Marine offers complete solutions for diesel and gas engine maintenance to cut downtime and save costs. Our extensive Grinding & Machining portfolio has been developed to overhaul and restore cylinder heads, cylinder liners and sealing surfaces.

Cylinder Heads

Grinding and machining of cylinder heads according to engine makers’ specifications is very important as failure to maintain the condition of cylinder heads means jeopardizing engine performance. This could become a very costly affair. The good news is that there is a variety of machines available to make maintenance accurate and efficient.

Chris-Marine offers a range of high-quality maintenance machines and tools to help customers keep their cylinder liners in top condition. There are products for 2-stroke and 4-stroke cylinder heads. Some products are pneumatically driven and others electrically driven. Some are portable while others are on the heavier side.

However, what they all have in common is that they are of high quality, and fulfilling engine makers’ specifications. As a result our customers can cut costs and avoid unnecessary down-time.

Product portfolio

• valve spindle & seat grinding machines
• valve seat & recess lathes
• working rigs
• valve seat removers

Cylinder Liners

Our extensive range of Grinding & Machining equipment for restoration and overhaul of 2-stroke and 4-stroke cylinder liners includes honing & deglazing machines, as well as machines for wave cut grinding and wear edge milling. We offer machines for honing in-situ or in a honing rig. Our ceramic honing stones and diamond honing stones are of great quality. Together with our honing liquid that prevents residues from clogging the stones, they ensure an efficient honing process. To facilitate the honing process we also have honing rigs and piston ring expanders in our product portfolio.

Why honing of cylinder liners?

The honing process rectifies longitudinal and circumferential surface geometry, thus restoring the cylinder liner’s oil retaining surface properties. Honing is vital to prolong the lifetime of cylinder liners and avoid running-in problems. If honing isn’t performed regularly there is a risk that the maximum wear limit provided by the engine makers won’t be reached before cylinder condition issues occur. Some common cylinder condition problems are broken piston rings and cylinder scuffing.

Honing results

The honing result depends on several process parameters such as honing speed, stone pressure, and number of strokes for each stage. Different types of stones are used throughout the process and up to five surface roughness parameters and several more geometrical parameters should be within a pre-specified range at the end of the honing process. This means that monitoring and controlling the process is challenging also for quite experienced users. Chris-Marine has therefore developed the Chris-Marine Honing App, a tool intended to make it easier to monitor and control the honing process, thereby improving quality while also saving time.

Sealing Surfaces

Grinding and machining of sealing surfaces according to engine makers’ specifications is very important as failure to do so means jeopardizing engine performance. Lower engine performance and possible down-time is costly and should be avoided. The good news is that there is a variety of machines available to make maintenance accurate and efficient.

Close

Ultrasonic Cleaning Chemicals

Our cleaning chemicals have been specifically designed and developed for ultrasonic cleaning methods and they enable enabling rapid penetration and removal of deposits.

Honing Liquid

Honing liquid prevents residues from clogging the honing stones and thereby ensures a smooth and efficient honing process.

Grinding Wheels

Choosing the right grinding wheels for a specific job is the key aspect for achieving superior grinding results. Therefore, the Chris-Marine grinding wheels have been carefully selected, tested and proven for each type of metal alloy, surface finish and workload.

Honing Stones

Honing time and stone consumption increase with cylinder diameter and stroke length. Because of this it is very important to select the right honing stones. We offer two types of honing stones: diamond stones and ceramic stones.

Diamond stones

Diamond stones have superior endurance and remove material faster than ceramic stones. They are therefore suitable for coarse honing of large engines or highly worn smaller engines.

Ceramic stones

Ceramic stones provide superior oil retaining properties for the cylinder liner and are therefore mandatory when finishing the running surface structure.
