SIMS3 and data utilization platform
Since 2008, NYK and MTI have developed and installed SIMS (Ship Information Management System), an onboard data server that collects navigational data such as ship position, speed, and fuel consumption. This system has enabled detailed analysis of fuel efficiency for operating vessels. The collected data is transmitted to shore via satellite communication, allowing close collaboration between ship and shore to optimize operations and improve fuel performance.
In 2013, we developed SIMS2, the next-generation system, upgrading it to a data server capable of collecting engine operation data and other engine-related information. This enhanced data collection has supported safer ship operations through early detection of engine abnormalities and preventive maintenance. Leveraging our expertise, we also actively contributed to international standardization efforts for onboard data utilization. In 2018, these efforts led to the establishment of two ISO standards:
- ISO 19847: Functional requirements for onboard data servers
- ISO 19848: Data naming standards for onboard systems
These standards significantly advanced the regulatory framework and environment for maritime data use.
Data utilization platform
Meanwhile, the emergence of faster satellite communication between ship and shore has made it possible to transmit more detailed and frequent data. In response, we developed SIMS3, the latest onboard data server. It complies with ISO standards and incorporates the expertise and technology gained from the previous SIMS generations.
SIMS3 enables real-time transmission of high-resolution onboard data, facilitating earlier detection of equipment anomalies and failures, as well as deeper situational awareness and more accurate responses.
Furthermore, we are enhancing SIMS to support the growing demand for alternative-fuel vessels, such as those powered by LNG and ammonia. These vessels feature larger, more complex engines and require advanced condition monitoring and analysis, including data acquisition from components beyond the main engine.
