Welcome to SAJ Instrument Ab Ltd,
Maker of dynamic measurement systems and software. The SAJ-DMS® Dynamic Monitoring System is a complete and intelligent concept for real time measurement of ship dynamics and considering hull flex bending and floating condition, in the most accurate and optimal way.

SAJ Instrument Ab Ltd is today considered as the pioneer within dynamic measurement of ships. The company introduced its first solution for dynamic measurement specifically designed for its purpose back in the seventies when the first oil crises hit the industry.  Developing unique instrumentation combining advanced formulas of mathematics ensure todays most complete and accurate real time measurement concept SAJ-DMS (Dynamic Monitoring System). On line measurement of ship dynamics and floating condition considering also the structural hull bending and torsion represents key information when operating ships. Information needed during cargo handling for exact verification prior sailing or once in seaway verifying the actual onset of dynamics.

It is a big difference from predicting a ship operation and trying to verify the historical performance all made based on estimates! SAJ Instrument have experienced that the most correct optimization can be direct obtained when accurate dynamic real measurement together with information from propulsion and navigation systems.  Specific modules have been developed as add-ons to the SAJ-DMS concept which makes it easy to update for optimal applicability and payback.
 
The SAJ system been installed in hundreds onboard all types of ships and floating constructions.
The goal of the SAJ Instrument has always been accuracy and functionality by well-proven features based on experience and continuous development.  
Because a system requires access to correct basic information about the ship's dynamics, it is natural that the SAJ-DMS concept can be supplemented with specific application modules that can guide carefully and accurately the user on the optimum dynamic operating condition. SAJ-DMS can thereby provide you with bunker savings, safety and operation improvement in many ways.

Any ship, regardless of size, is affected by dynamic effects when setting speed through water which makes it important to monitor the direct onset of dynamic forces due to depth under keel, wind, sea state, ice etc. It is a fact that the dynamic condition has a major impact on bunker consumption and safety when navigating in shallow water.

Get a dynamic measuring mind-set!

Considering today's conventional standards of simple gauges and devices with low accuracy that neither work satisfactory in port nor at sea, are known to require continuous calibration and repair, its time to consider a modern standard that works and benefit Your operation.

When a ship's initial design is made, the dynamic effects on the hull is evaluated and determined for different cargo load, trim and power outtake by computer simulations or tank towing tests. All to document the optimal running condition. With respect to that, each one realize it is important to have instrumentation capable of measuring the actual dynamic condition in order to operate closer to the optimal dynamic running condition.

Its time to stop operating on feelings!

The SAJ-DMS® system is easy to install also as retrofit. The system uses tailor made core technology utilizing intelligent hardware and software modules that are all based on experience obtained under three decades of developing dynamic systems.

Its time to consider a SAJ-DMS® standard for your ships and new build projects!

We are committed to supplying the best standard of system for measuring of ship dynamics considering our customers demand now and in the future.
