• Green Technologies for Existing Ships: RETROFIT & GRIP Midterm Conference

    On 7th November, the two EU FP7 projects RETROFIT and GRIP organise the midterm conference 'Green technologies for existing ships'. The conference will be held during Europort 2013 in Rotterdam, the Netherlands.

    A unique event to foster knowledge, sharing and exchange experiences regarding updating existing ships with the retrofitting of green technologies.

    The conference programme includes presentations of experts, a panel discussion and the possibility to meet the speakers and other conference participants. Download the complete programme of the conference here.

  • Period 1 Review Meeting - Brussels, Belgium, 13th June 2013

    The 1st Periodic Review of GRIP was held during the 13th June 2013 in Brussels, Belgium.

    The project recieved very positive feedback from the EC Project Officer, Mr Ronald Vopel, and the Project Reviewer, Mr Maciej Reichel from CTO. GRIP is now looking forward to the next 18 months with the progress of all work packages and the validation of results obtained.

Organizational Activities

Founded in 1913, HSVA – Hamburgische Schiffbau Versuchsanstalt GmbH - is a private, self-supporting, non profit research centre providing hydrodynamic services to the maritime industry. The model basin operates a number of sophisticated experimental facilities including a 300x18x6 m towing tank, the large hydrodynamics and cavitation tunnel (HYKAT) which permits the use of whole ship models within the test section and a dedicated ice basin.
HSVA has since long pioneered marine CFD development and applications. Starting with free surface potential flow methods in the early 80’s more advanced and refined methods for ship and propeller flows have constantly be developed and applied. This covers dedicated RANS methods for problems related to free surface flows, propeller predictions up to the numerical simulation of propulsion tests.

Role in the Project

HSVA will contribute to the definition and implementation of the early assessment system in WP1, develop design and flow analysis tools in WP2, provide interface with hydrodynamic data in WP3 and design customised ESDs for a number of ship (types) in WP5.
CFD development work covering:

  • Parametric modelling of energy saving devices
  • Grid deformation technique
  • Simulation driven design optimisation of ESDs
  • Verification and validation practices on reference test cases
  • Operational performance
  • Assessment of cavitation
  • Enhanced numerical optimisation models

Key Personnel

Yan Xing-Kaeding, Dr.: has received her master degree in 2000 from Dalian University of Technology (China) and her PhD in 2006 from Technical University Hamburg-Harburg with a thesis on ship seakeeping and manoeuvring by a RANSE method. Since then she worked in the aerospace sector in the field of environmental control systems (ATA21) as systems engineer and CFD project leader. In 2011 she joined Hamburgische Schiffbau-Versuchsanstalt - HSVA, working as a research engineer and project manager. She specialises in RANS code development (e.g. Fresco, the new RANS code jointly developed by HSVA and TUHH) and application with a focus on free surface, ship motions in waves, ship manoeuvring applications and design optimisation.
