Sino-Greek research project examines LNG usage by ships

NhognwmwnSince 2012 Greece and China have co-operated at the research level in order to examine the potential usage of LNG by open type ferries and large containerships. The Greek partners of the project are the Hellenic Register of Shipping S.A. and the Department of Naval Architecture of Technological Educational Institute of Athens. The the Harbin Engineering University and the China International Marine Containers Ltd.  The basic concept of the present work has been the development of new technology and technical Regulatory framework for conversion of the existing shuttle ferries and containerships in order their diesel propulsion plants to operate on either using LNG or Diesel fuel. Two types of ships were involved; open type ferries and large containerships. The Greek side focused on the shuttle ferries operating on (Greek) domestic routes and the Chinese side on the containerships operating on national and international routes.

The results of the project can be summarised as follows:

  • Full set of plans and procedures required for an open type ferry to be issued a conversion permit towards the conversion of her propulsion plant into a dual fueled Diesel-LNG engine. Development of new technical Rules and Regulations governing the conversion of open type ferries and operate their main propulsion engines on either natural gas or diesel fuel.
  • Theoretical and experimental investigations of the parameters affecting the Diesel-LNG fueled engine performance (power output, emissions etc.).
  • Theoretical investigation of the critical parts/assemblies of the LNG fueling system (i.e. storage tanks, piping, cryogenic system, gasification system etc.) for open type ferries and containerships.
  • Technical requirements and specifications of ship safety arrangements (i.e. fire fighting, gas detection, ship evacuation etc.).
  • Investigation of LNG bunkering alternatives at national (Greece-China) and international level.
  •  Estimate the cost effectiveness of the proposed schemes for the Greek and Chinese sides.
  • Environmental evaluation of the proposed schemes (gaseous emissions, EEDI, EEOI).

The research project LNG-COMSHIP is implemented under the Bilateral R&T Cooperation between Greece and China 2012-2014, under the National Action “Bilateral, Multilateral and Regional R&T Cooperation” of the General Secretary of Research and Technology and co-financed by the European Regional Development Fund (ERDF) of the European Union and by National resources.
