What : Flexible fuel market : Development of a fuel inject ion system for mult i-fuel purposes in most

cost -effect ive manner & comply with regulat ions 3 partnerships with leading inst itut ions, sharing best pract ises (PSI, FHNW,

OMT) Studies expect HFO share between 50 to 70% by 2030 depending on

global sulphur cap. Rest is most ly MDO/ MGO and between 5-15% LNG Why

Drivers: Fuel demand to double unt il 2030 (LR) Shipping indust ry must stay open for opt ions (environmental legislat ions

(ECAs) vs. sulphur cap vs. pricing vs. fuel availabilit y)

Summary and conclusions

27

The further evolution of environmental regulations in combination with changing market requirements is triggering s ubs tantial development efforts

Various technologies are applied and developed for achieving improved overall engine and propuls ion s ys tems performance and lower emis s ions with the focus on:

−Conventional combus tion proces s improvement (increas e P max, injection s ys tem & s trategy, etc.)

− Fuel flexibility

− S CR / E GR

− Intelligent engine lifetime management

The new Generation X E ngine s eries is res ponding to the market need for highly efficient engines s uitable for modern s hip des igns bas ed on s lim hulls and low rated s peeds

WinGD has developed and delivered a new s eries of 2 -s troke low pres s ure dual-fuel engines that is inherently Tier III compliant and offers full fuel flexibility
