Economic Benefits of SOPass

  • Example01

    What can SOPass do for a voyage from Japan to Panama Canal?
    For your particular vessel, SOPass proposes the optimum cargo operation with fuel unit prices factored in, and the most fuel-efficient route.
    You will be saving as much as 30, 000 US dollars in one single voyage of this route over the Pacific Ocean!!
  • Example02

    What happens when SOPass optimizes amount of heel for my LNG carrier?
    Using SOPass, you will be having your voyage with just the right amount of heel in the tank—not too much, not too little. That way you will be maximizing the amount of LNG that can be carried and traded.
    Within a year you will be transporting 600,000 US dollars more worth of LNG!!

SOPass is not just for visualizing data. Look into your future.

Collect, analyze, and visualize data. SOPass does all of that, and then some- looking into the future with our forecasting feature. Our team of experts has developed models for ship-motions and for heat transfer for LNG tanks. These models are used to simulate voyages at a high level, reflecting changes in rolling/pitching or heat ingress, and to forecast how your cargo and optimum routing may transition over the course of your voyage.

Support your vessel operation with Land-Sea communication

SOPass not only collects information from ships, but also sends forecast information about voyages to vessels to support optimal vessel operations. Voyage forecast information carefully examined on land can be easily shared with the vessel with a single click, and the same voyage simulation can be viewed onboard.

Get New Insights

Based on the big data that have accumulated over the years, SOPass provides insightful information in an easy-to-see format.

Data-Driven Decision Making

Make decisions based on data analyzed by SOPass, rather than relying on experience and intuition. Reliable analysis data support customers’ business decisions and solves problems.

The first-in-the industry functionality, specialized for LNG carriers

BOG-Navigation, one of the SOPass applications, is the first-in- the-industry functionality specialized for LNG carriers. Based on the data on weather and sea conditions as well as ship motion models, this app accurately predicts natural BOG (boil- off gas) that is produced during LNG transportation, and proposes the most fuel-efficient route.
In addition, during laden voyages, BOG-Navigation proposes the optimum amount of heel for voyage operation, so you can maximize the amount of LNG to be unloaded.
By improving the efficiency of LNG carrier operation with SOPass, economic benefits will greatly exceed initial cost of installation.


“Monitoring” and “Reporting”
applications are customizable

SOPass not only allows you to choose apps that match your business flow, but also to customize apps. For example, with the “Monitoring” application, you can check the cargo status and propulsion plant status on a graphics screen catered to your vessel.
The “Reporting” application is equipped with a report generation function that meet your needs, considerably reducing your work load. Many kinds of reports are available for customization to reflect customers’ voices, including Daily Report, Voyage Report, Environmental Report, and CII Report.

Simulation technology
that takes full advantage of our expertise in shipbuilding

Utilizing the knowledge of shipbuilding accumulated over many years here at Kawasaki Heavy Industries, SOPass has realized advanced voyage simulation and weather routing that reflect the ship motion characteristics and the heat transfer status of the tanks. Our expertise in shipbuilding is also fully applied to applications that analyze the propulsion performance and fuel efficiency of vessels.

We follow through- From the first step of SOPass installation

We will be there by your side from the contract stage through SOPass installation, to answer any of the questions you may have. We support customers every step of the way—together with customers, Kawasaki Heavy Industries serves to achieve economic voyage operation and reduce operational burden.
