Fuel savings from

hydrodynamic conditions

The SAJ-DMS system

is the marine industry’s most accurate, reliable and proven dynamic remote measuring system. The system is well suited for newbuild projects as well as for retrofit projects. The system can replace outdated and failing older systems and this upgrade will give the users the added benefit of the industry’s best accuracy and reliability.

On-line Optimization

Trim optimization is a key factor for vessel performance and efficiency. We use Computer Fluid Dynamics (CFD) data to find out and continously calculate the most optimal trim in different conditions. This will save fuel and  lower the environmental footprint. We provide tools to calculate and display optimization data on-line and in real time on the bridge.

Our Solutions

Ultimate DYNAMIC MEASURING solutions

Measuring platform

The SAJ-DMS system comprises one to three dynamic sensors depending on the type and length of the ship. Our dynamic sensors measure the ship’s trim and heel.

Trim List Indication

Dynamic trim and heel indication presented on-line! Extreme accuracy and resilience in operation will benefit to increased safety and better economy!

Trim Optimization

The SAJ-DMS dynamic monitoring platform brings trim optimization to a new level. The module can easily be added to the DMS system and will immediately increase your fuel efficency.

Our services

We provide all the services required to successfully make use of the full potential of the SAJ-DMS system thrugout the lifetime of the system. We are available to help in all situations.

Project planning

A vital part of the installation is proper planning. Proper location of the sensors are required to get full benefits of the advanced dynamic measuring system.


When it is time for installation of the system onboard we provide the required support as well as on-site installation of the system.

Service & Support

After successful implementation we will provide you with service and support to make sure you make efficient use of your new measuring system.
