Overview
The MARSIC300 ship emissions measuring device from SICK is a customized solution for reliably measuring emissions on ships according to MARPOL Annex VI and IMO MEPC. The MARSIC300 is type-approved for this application by well-known classification organizations. The MARSIC300 measures both SOx and CO2 upstream and downstream of the scrubbers, and NOx upstream and downstream of SCR (selective catalytic reduction) plants.
An experienced manufacturer of emissions measurement technology, SICK is offering the MARSIC300 as a compact complete system. Designed to be used on ships, the measuring device impresses with extremely low maintenance costs and modules that are easy to replace.
- Rugged design and high level of measurement accuracy
- Type-approved by well-known classification organizations in accordance with MARPOL Annex VI and IMO MEPC
- Measuring ranges adapted to low and high concentrations of SO2 and NOx
- Up to 7 measuring components at the same time: SO2, CO2, CO, NO, NO2, NH3, H2O
Advantages
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 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 MARSIC300 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
The MARSIC300 measures CO2 emissions from combustion processes and ship engines. The MARSIC300 also measures methane, which damages the world’s climate. Methane is produced during incomplete combustion of LNG in 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 MARSIC300, 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.

The MARSIC300 has hardly any wear parts or moving parts and can be calibrated using internal calibration filters.

The MARSIC300 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.

Internet use on the high seas enables the MARSIC300 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

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.

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.

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