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. Several classification organizations have type-approved the measuring device for this application.

With the MARSIC280, SICK, a leading manufacturer of maritime emission measurement technology, has created a solution based on many years of practical experience. It shines due 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.

Intelligent solutions for the shipping industry

As one of the market leaders in onshore emissions measurement technology, SICK has decades of experience in the development of gas analyzers s 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 repeatedly proven technology, which has demonstrated its quality and reliability all over the world. SICK now has one of the largest numbers of ship emissions measuring devices installed worldwide and has established itself as one of the leading manufacturers in the area of maritime emission control.

For clean air on the high seas

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, safe in 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 has hardly any wear 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 state-of-the-art 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 always monitor what the emission measurement device is currently measuring at sea.

Always on a safe course with the right service

With its worldwide network of employees, SICK makes sure that services and spare parts are available. To satisfy its global demand, SICK has established several maritime service hubs to coordinate and actively support its worldwide 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 global 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 most 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 in real time. This means that the ship operator can always 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.

Global availability for maximum efficiency

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