The gearbox OptixDrive lower fuel consumption with up to 25% for ships with shaft generator - Enabling main engines to run on variable (optimal) rpm instead of fixed rpm


  • Tests show that OptixDrive can lower fuel consumption with as much as 25% (700 ton fuel per ship and year) through enabling the main engine to run on "combination mode"
  • 95% of all blackouts onboard will be eliminated since OptixDrive gives you the buffer time needed to start your emergency generator before the ship goes pitch black
  • In average OptixDrive is estimated to save 500 ton fuel per ship and year, meaning lowering emissions with as much as 1500 ton CO2







   How does it work?

  • Transmission is installed between the Power Take Out (PTO) and the shaft generator
  • Gearbox uses hydraulic power to compensate for reduced primary speed and adjusts the secondary speed to the generator's prefered rpm
  • Your shaft generator can be connected from idling up to maximum rpm - saving hundreds of tons of fuel annually & lower emissions of CO2, NOx & SOx
  • 95% of all "blackouts" onboard are eliminated through the rpm compensation continuing below idling rpm - resulting in the buffert time needed for starting auxiliary generators taking over electrical power production onboard
  • Optixdrive is provided in different models (e.g. 1,0 / 1,2 / 1,5) with a power range up to 3,5MW
  • Installation is adaptive and can fit your specific vessel with no docking or "off hire" needed during the job that takes approximately 24h

Optixdrive is estimated to save as much as 1 500 tons of CO2 per ship & year

To give an overview of the potential environmental impact, imagine the effect of the world wide fleet of 7 000 ships using shaft generators:

  • 1 500 ton less CO2 per year x 7 000 ships = 10 500 000 ton CO2

We believe that Optixdrive has the possibility to have a serious positive effect on the shipping industry's total emission of CO2, NOx & SOx.





Next generation fuel pump control

The fuel pump controlsystem OptixAutorail lower fuel consumption with up to 10% for engines equipted with individual fuelpumps. Enabling each individual cylinders fuelpump to be controlled to the most optimum power and cylinder-load.

  • Run your main engine with even exhaust temperatures at all rpm levels
  • All cylinders add equal power
  • Even wear on bearings and pistons
  • Load reduction only occurs when all cylinders are overloaded
  • Reduce fuel consumption and emissions from COx, NOx, & SOx

Even cylinder power takeout

On a standard fuelrack controlled engine the power takeout varies between the cylinders. It is common that exhaust temperatures vary of as much as 75 degrees and as a result of this the engine gets big variation in cylinderload. To reduce the fuel consumption on a engine the easiest way is to reduce the rpm and load the engine on lower rpm. However, the result of this is quite common also increased exhaust temperatures. The turbine temperature is a result of the highest cylinder exhaust temperature. When a high turbine temperature occurs the load control system deload the propeller.

With OptixAutorail system installed all cylinders have the same power takeout and therefore the deload only occurs when all cylinders are overloaded. After installation the exhaust deviation is within 5-10 degrees as standard.

Easy installation and tuning

The OptixAutorail controlmodules are installed on each individual fuelpump. The exhaust temperature on each cylinder exhaust is measured and the individual fuel pump module is controlled with this as one of the references. During the installation the original fuelrack is disconnected and the original regulator is replaced by the controlprocessor in the OptixAutorail system. To get a more exact engine rpm the OptixAutorail system has a separate rpm pickup.
Mechanical installation is done in two days by OptixMarine installation team and thereafter one engineer joins the vessel for one day to tune the system to the specific engine. No docking or of-hire is needed for the installation.

Get forecast on wear and maintenance

OptixAutorail is ethernet connected and uploads condition reports of each part in the system. This information includes daily calibration settings, variations in demanded fuelpump settings etc. Based on this data the system is able to perform forecast calculation related to engine wear, maintenance demand and other issues in the engines controlsystem.

OptixAutorail is suitable for all ships

The OptixAutorail can work as a “stand alone” system together with the ships control system or in cooperation with a optimisation system/ software. Most tuning and optimisation systems “listen” to the existing data from the engine as it is today. They do their best to optimise and reduce fuelconsumption on the engine. However, it all come down to the correctness of the received data from the engine. If the temp from one cylinder is too high, the system will reduce the load on the engine. Hence the optimisation system is “fooled” by the engines data.
The OptixAutorail system is active within the engine instead of just listening to it. The result is that all systems that are listening to the engine will get correct data and therefore perform better. An installation of this system will result in fuelconsumption reduction of up to 10%.

The OptixMarine Team have more than 25 years experience in ships systems and believe that the shipping industry has a sustainable future. Our goal is to use this experiences and knowledge to lower energy consumption onboard ships.

2018 November - Rederi AB Donsötank signs contract for two OptixDrives

We welcome Rederi AB Donsötank to the OptixMarine family! The have signed orders for two OptixDrive for their ships M/T Solando and M/T Solero. First delivery in april 2019 for the Solando and august 2019 for the Solero.

2018 September/ October - Veritas Astorias installation summary 

"Free electricity during voyage"

AB Veritas tankers, Veritas Astorias OptixDrive has now been running for almost thousand hours. The final result in savings during a period of two months with same conditions in 2016 and 2018 have resulted in a decrease of main engine fuel consumption with 1kg/Nm including the production of 300kw from the shaft generator for the hotel load during vouage. In short term the increase of main engine efficiency due to the kw load from the shaft generator (that does not affect the hydrodynamics of the hull) has resulted that all kw produced by the main engine is more efficient. The result is a reduction with 1kg/Nm and free electricity during voyage. The annual savings for Veritas tanker and the Veritas Astoria is approx, $240 000.

2018 August - Veritas Astorias installation is finalised

AB Veritas tankers, Veritas Astorias OptixDrive is now installed and in service. The unit has been running stabile and with good results for over 300 hours onboard. Maximum load so far has been 700kw and the output result has been +- 0,2hz in maximum frequency drop.
