Reliably on the right course

The MARSIC280 from SICK is a cost-optimized solution for reliably measuring emissions on ships according to MARPOL Annex VI and IMO MEPC. MARSIC280 is designed for measurement of SO2 and CO2 downstream of the scrubber. Classification organizations have type-approved the measuring device for this application.

With the MARSIC280, SICK, an experienced manufacturer of maritime emission measurement technology, has created a solution based on many years of practical experience. It impresses thanks to its simple mounting and minimal maintenance requirements. Modules can be easily exchanged due to a replacement concept. Thanks to the use of standardized units, for example from the MARSIC300, the MARSIC280 offers flexibility and reduces the need for spare parts storage.

At a glance
  • Rugged design and high level of measurement accuracy
  • Type-approved by classification organizations in accordance with MARPOL Annex VI and IMO MEPC
  • Designed for SO2 and CO2 measurement downstream of the scrubber
  • Use of field-tested MARSIC300 components


Intelligent solutions for the shipping industry

As one of the proven suppliers in onshore emissions measurement technology, SICK has decades of experience in the development of gas analyzers and emissions measurement. In addition, SICK offers a comprehensive portfolio of on-board measurement systems and has many years of experience in maritime applications. The MARSIC280 ship emission measuring device therefore consists of proven technology, which has demonstrated its quality and reliability a thousand times over. SICK has installed a large number of ship emissions measuring devices and has established itself as a reliable manufacturer in the area of maritime emission monitoring.

For clean air on the high seas

The MARSIC280 measures CO2 emissions from combustion processes and ship engines. The sensors from SICK send the measured values from on board directly to the cloud and show the corresponding data, e.g. energy efficiency, in a transparent manner. With the MARSIC280, the ship emission measuring device from SICK, you can sail across all seas with DNV certification with the knowledge that the measured values are reliably accessible in maritime emission control areas. You can also rest assured that device maintenance and calibration costs will stay low in the long term.
Efficient solution that reduces costs

The MARSIC280 boasts minimal maintenance requirements, has almost no wear and tear parts or moving parts and can be calibrated using internal calibration filters.

Modular design enables quick and easy installation

Short installation time due to pre-assembled mounting frame for the analyzer and preconfigured connecting cables.

The MARSIC280 pays for itself quickly

The MARSIC280 quickly pays for itself in combination with modern exhaust gas purification systems, as it can save costs depending on the type of fuel.

More transparency on the world’s oceans

Internet use on the high seas enables the MARSIC280 to continuously send data to cloud-based solutions. This means that the ship operator can monitor what the emission measurement device is currently measuring at sea.

SICK Maritime Suite: More transparency on the world’s oceans

Benefit from the experience of a leading manufacturer in maritime emission monitoring! Using the digital services in the SICK Maritime Suite such as the MARtracker, the live data of the emission monitoring device of the ship can be combined with other data such as the position of the ship as well as ECA and local emission regulations. The result: Tailored status messages, more transparency over your entire fleet, and an optimization of operating costs.

On a safe course with the right service

With its extensive network of employees, SICK makes sure that services and spare parts are available. To satisfy its international demand, SICK has established several regional maritime service hubs to coordinate and actively support its service activities. In addition, training centers enable the company to pass on its detailed knowledge about the products and their peripherals to customers. Qualified staff from SICK and its partners are ready to serve you along the main international shipping routes. The staff provides technical support, solves problems, helps with preventive maintenance and provides other services for measurement technology.

MARITIME SERVICES from SICK – on site where you need us

We help you help yourself

SICK supports you with regular maintenance with its network of service experts. And with proper training, customers can perform common maintenance activities on their own. If the ship has a changing crew, e-learning is a good way to explain the maintenance tasks that need to be performed. As often as you want, regardless of the time or location.

More transparency on the world’s oceans In the cloud-based SICK AssetHub, a web service for SICK customers, various SICK sensors can be mapped out and the data from the devices displayed promptly. This means that the ship operator can monitor what the device is currently measuring at sea. In the event of a problem, such as a clogged filter, the crew as well as the shipping company receives a notification and can initiate appropriate measures.
International availability for high efficiency

Extended warranty, SICK Remote Service, 24-hour help desk, maintenance, availability guarantees and other modular services can be individually combined on request.
