Engine control system WECS 8000

The functionality of WECS 8000 comprises the following main categories: Handling of engine slowturning, start & stop sequences

Changing of fuel modes

Instrumentation & communication

Speed measurement

Engine safety

Speed/load control

Gas pressure- & gas admission control

Pilot pressure- & pilot injection control

Air/fuel ratio control

Cylinder balancing & knock control

Hardwired engine safety module (backup)

NATURAL GAS IS VERY CLEAN FUEL!

LESS ABRASIVE AND CORROSIVE COMBUSTION PRODUCTS

CLEANER LUBRICATING OIL

LESS CLEANING OF ENGINE PARTS DURING MAINTENANCE

LONGER TIME PERIODS BETWEEN OVERHAULS MINOR ROUTINE MAINTENANCE CAN BE PERFORMED DURING TERMINAL CALLS OR DURING SAILING OVERHAULS CAN MOSTLY BE TIMED TO BE CARRIED OUT DURING DOCKING (DEPENDING ON 2.5 OR 5 YEARS DOCKING INTERVALS) Flexibly mounted constant speed engine transmits minimum vibration to hull structure. The generator can be rigidly mounted.

This concept is well proven in cruise ship installations.

(148 flexibly mounted W46 engines with rigidly mounted generators in 33

cruise ships!)

Dual-fuel engines:

Have a higher thermalefficiency

Use cleaner fuel

Apply lean burncombustion principle

And therefore have:

Virtually no SOX

Lowest CO2

Lowest NOX
