LeanShips Project General Principles The project has received funding from the European’s Horizon 2020 research and innovation programme (Contract No.: 636146)

Project goal: To develop green technologies…… The missing link between green technology availability and large scale market uptake is: “Hard” evidence on green technology reliability, impact on energy use and on emissions and the economic gains to compensate for the necessary investments.

The Smart, Green, Integrated Transport Challenge Mobility for Growth, technical development, modes and integration Better use of existing resources, reduced congestion, intelligent systems Cleaner, safer vehicles

It’s all about innovation! Getting new green technology to the market! And LeanShips sets a green example: - in the maritime sector; - in line with EU; - worldwide energy and emission policies.

Work Package 04 LNG/CNG combined with RSD for shiphandling tug Sneak inside the project Partners : Start up: May 2015 Duration: 48 months Work Package 04 LNG/CNG combined with RSD for shiphandling tug

Objective of the Work Package 04 Design and build a new generation ship handling prototype tug with two NG-fuelled prototype engines; NG-fuelled high speed engines concept; Build and (bench) test 3 prototype high-speed NG fuelled engines; Validate (at full scale) new generation ship handling tug by operating the tug for one year; Based on sea measurements & bench tests, develop 2nd generation NG-fuelled engines; Retrofit/update/modify the NG-fuelled engines on-board the tug with the 2nd generation engine technology.
