MarPrime Instruct is part of the MarPrime System, an all-in-one solution of cylinder pressure handheld devices: New key feature of this software evaluating engine performance is the ability to calculate the Carbon Intensity Indicator (CII), including the calculation of the CII snapshot, based on the current measurement, the identification of potential fuel savings to optimize the CII and a preview of the trend of the CII. MarPrime Instruct optimizes the engine operation for high engine reliability, low fuel and cylinder consumption. Errors and saving potentials will be identified and analyzed, clear instructions for efficient usage will be shown to the operator.

The software MarPrime Instruct makes any other additional software expendable


In combination with MarPrime Ultra, our software MarPrime Instruct makes any further additional software dispensable. It determines the performance of your engine and provides comparisons with other parameters. Once installed, MarPrime Instruct immediately provides all the critical information you need to ensure optimal performance. Data regarding potential savings in fuel and lubricating oil consumption is compiled for immediate conclusions. Charterers receive a compelling report that meets their requirements in all respects: A successful operation of the vessel and a transparent, economically convincing performance are comprehensively presented to your partners. With its interface to the PMI system, MarPrime Instruct works on every vessel worldwide via the CoCoS system. This import option can be used for all electronic controlled engines – analyze, optimize and operate efficiently.

MarPrime and MarPrime Ultra, offering full assessment of your engines, coming from a single unit: A “one-hand/ one-person” tool and part of the MarPrime System. The Ultra version includes an ultrasonic sensor.

FULLY compatible SOFTWARE SYSTEM, Immediately usable on all devices

MarPrime Instruct not only forms a central part of the MarPrime System, our highly compatible software also works on all relevant third-party devices. This provides the crucial basis for a fast and trouble-free conversion ensuring all-in-one reports immediately after installation. The software can be easily installed and works directly on every vessel worldwide via the CoCoS system. This data import option can be used for all electronic controlled engines and results in two decisive advantages:

  1. Secure data import: The operation data from an exported CSV file will be imported automatically into the input mask of MarPrime Instruct to avoid manual readings, incorrect entries and additional measurements.

  2. Adjustment to your needs: Parameter names may differ between CoCos installations on different vessels. For this reason, these names were outsourced to an external file and can be adapted to the configuration without carrying out another MarPrime Instruct update.
