Precision Coating Thickness Measurement with CTM
Chris-Marine’s Coating Thickness Measurement tool (CTM) delivers precise readings of coating thickness on both magnetic and non-magnetic base materials. This tool is essential for assessing the remaining lifetime of coated piston rings in 2-stroke engines. With a liner time scale of approximately 1000 Rh and a measurement time of just 15 minutes per liner, CTM provides fast, accurate results.
Key Benefits for Condition-Based Monitoring
CTM is designed for condition-based monitoring of piston rings, ensuring optimal engine performance. It measures non-magnetic coatings on magnetic materials, such as chromium-plated or plasma-coated cast iron, and non-magnetic coatings on non-magnetic materials, like plastic-coated stainless steel. The tool automatically detects the base material’s type, simplifying the process for users.
Compact, user-friendly and enables reliable measurements even in hard-to-reach areas. This makes it a practical choice for in-situ, non-destructive testing, contributing to more efficient maintenance planning.
The CTM combines ease of use with advanced technology, providing accurate measurements and helping optimize engine maintenance strategies.

Fast In-Situ Cylinder Liner Inspection
The Chris-Marine Liner Condition Camera (LCC) enables accurate cylinder liner condition monitoring without removing the cylinder cover or exhaust valve housing. Designed for 2-stroke engines with bore sizes from 480 to 980 mm, the LCC captures high-quality images of the entire liner wall and piston ring pack. As a result, engineers reduce inspection time significantly while improving documentation accuracy compared to traditional borescope inspections.
High-Resolution Imaging for Condition-Based Maintenance
Using the LCC, operators can precisely evaluate liner cleanliness, wear edge formation, honing marks, wave-cut groove extension, and corrosive wear. Moreover, the system clearly documents black lacquering and bore polishing, enabling early detection of abnormal wear. Consequently, maintenance decisions become faster, more reliable, and more cost-efficient than with competing liner condition camera.
Advanced Multi-Camera Technology
The LCC features four integrated cameras that together document the complete running surface. Cameras 1–3 capture slightly overlapping liner wall sectors, while Camera 4 inspects injectors and the exhaust valve area. Additionally, a tablet-mounted camera documents the piston ring pack and top land condition. Thanks to the laser-triggered LED flash system, the LCC collects only relevant images, thereby minimizing battery consumption and unnecessary data storage.
Time-Saving, Heat-Resistant, and Easy to Use
Unlike many alternative cylinder inspection tools, the LCC operates with high-temperature-resistant electronics and batteries, allowing inspections without lowering engine coolant temperature. Therefore, operators save valuable time during routine checks. Furthermore, only combustion chamber venting is required. On average, the system documents one cylinder in approximately 15 minutes, while a fully charged battery set supports up to 14 cylinders per session.

Fast and Accurate Cylinder Liner Measurements Onboard
The Chris-Marine Liner Diameter Measurement (LDM) system enables precise cylinder liner diameter measurements without removing the cylinder head or exhaust valve housing. Designed for 2-stroke engines with bore sizes from 500 to 980 mm, the LDM measures liner wear and clover-leaf deformation quickly and reliably. As a result, operators save significant time compared to traditional liner measurement methods.
Efficient Condition-Based Liner Maintenance
With the LDM, a single operator can measure one cylinder in approximately one hour, capturing up to 26 measurement levels. In contrast, conventional measurement techniques often require a three-person team and a full working day. Therefore, the LDM significantly reduces downtime, labor costs, and preparation time, making it an efficient alternative to other liner wear measurement tools.
Detect Abnormal Wear and Clover Leafing Early
The LDM accurately identifies non-oval liner wear, including clover leafing caused by slow steaming retrofits, injector erosion, and uneven lubrication. Consequently, engineers can implement corrective actions before damage escalates. Moreover, the system supports continuous liner wear monitoring, ideal for dock preparation and condition-based maintenance strategies. Compared with competing liner measurement systems, the LDM delivers higher accuracy and faster diagnostics.
User-Friendly Design for Onboard and Workshop Use
Chris-Marine offers the LDM in both an easy-to-use onboard version and a workshop version with a rugged case, micrometer set, and calibration rig. In addition, the handheld tablet interface provides remote technical support and software updates. The latest generation also delivers up to 13 hours of continuous operation, further improving usability. The LDM supports MAN B&W, Wärtsilä, and Mitsubishi 2-stroke engines, offering broad compatibility unmatched by many alternative brands.

The IMO has set the target to mitigate CO2 emissions from ships by at least 40% by 2030 compared to 2008 levels. To meet this target, IMO has adopted Energy Efficiency Existing Ship Index (EEXI) and CII, a set of amendments to existing regulations to reduce greenhouse gas emissions from vessels.
Where CII is an indicator of how efficient vessels operate, EEXI is the new IMO framework setting the minimum design efficiency of existing ships with Gross Tonnage over 400 GT falling under MARPOL Annex VI.
With just few months to go, ship owners and managers will need to prepare for EEXI requirements in advance by investing in appropriate solutions, taking the time needed to assess and improve their vessels. This is crucial to ensure that their fleets are ready by the beginning of 2023, having demonstrated compliance and having been granted the proper certificates to carry on trading internationally.
To help its customers comply with EEXI requirements, Chris-Marine has developed a Shaft Power Limitation (ShaPoLi) solution that will enable existing ships to meet the minimal energy efficiency level to comply with the upcoming regulations.
ShaPoLi system
The Shaftpower system measures the actual power and limits it at the maximum allowed to meet the ship’s required EEXI. The system is designed according to the GUIDANCE of major classification societies and the approval process is ongoing.
Override function
To ensure safety at sea, the system is overridable in case of an emergency and overrides are automatically logged and easily audited by the relevant authorities through our SPEAT display on the bridge.
Combine EEXI compliance with an Optimum CII rating
The Carbon Intensity Indicator (CII) is an operational measure, targeting the continuous improvement of the actual energy efficiency of the vessel and is measured in grams of CO2 emitted by cargo-carrying capacity and nautical mile.
For ship owners to optimize their ship´s performance, there are several concrete actions they may undertake to enhance how efficient they can operate their fleet and lower CO2 emissions. One effective way to keep the CII under control is to monitor ship performance, including fuel consumption, and power output and use the data to decide on timely engine maintenance and hull cleaning. Those actions may be performed immediately, with up-to-date ship performance data enabling safe and efficient way of vessel operation.
Our onboard SPEAT system is designed to monitor and improve ship operation by raising crew awareness through Key Performance Indicators, allowing a cut in fuel consumption, and enabling ship operators to remain competitive in the market while increasing profitability at the same time. Our ship performance monitor provides a set of tools to operate ships in more economical, environmentally friendly, and thus sustainable ways.
How it works
LEMAG SPEAT is designed to give the ship operator instantaneous status of the vessel’s operational performance. Data is collected from the shaft power meter, fuel flowmeters and different navigational instruments. Collected data is analyzed and compared against a benchmark using Key Performance Indicators in real-time, enabling the master or the officer of the watch to assess, evaluate and take the best decision. LEMAG SPEAT is a future-proof system which can be extended with further interfaces to monitor new process areas and enhance functionality.
