The HOLISHIP approach brings together all relevant main disciplines of maritime product design under the umbrella of advanced parametric modelling tools and integrated s/w platforms enabling the parametric, multi-objective and -disciplinary optimisation of maritime products. The approach includes: market analysis and demand, economic and efficiency considerations, hull form design, structural design, selection of prime movers and outfitting. Together they form the mission requirements and enable the formulation of a rational foresight analysis for the viability of the product model over its life cycle (“from cradle to cradle”). It considers all fundamental steps of the traditional “ship – design spiral”, which, however, are better illustrated today by a systemic approach, which is herein implemented in practice by a “shell/synthesis of integrated design s/w tools”, as shown in 1.

Resistance and Powering Demonstrator

HOLISHIP Platform: Web App using CAESES and ν-Shallo

As the first stage in the on-going project developments, a demonstration of the resistance & power prediction for a RoPax ferry is available.This demonstrator of the HOLISHIP platform combines the parametric design capabilities of CAESES with the potential-based resistance prediction of ν-Shallo. Click on the screenshot, or follow this link to launch the web app. This is a live preview of CAESES running on a remote server.
More information on ν-Shallo is available on the HSVA website.
More information and other web apps are available on the CAESES website.

The proposed HOLISHIP synthesis model follows modern Computer Aided Engineering (CAE) procedures and integrates techno-economic databases, calculation and optimisation modules and s/w tools along with a complete virtual model [Virtual Vessel Framework – VVF] which will allow the virtual testing before the building phase of a new vessel. Modern GUI and information exchange systems will allow the exploration of the huge design space to a much larger extent than today and will lead to new insights and promising new design alternatives. The coverage of the ship systems will not be limited to conceptual design, but extend also to relevant major onboard systems / components. Their assessment in terms of life-cycle performance is expected to build up further knowledge of suitable outfitting details, this being a highly relevant aspect especially for the outfitting-intensive products of European Shipyards.

Consequently, the project is structured into three main work clusters:

  • Tool development: methods and s/w tools for the individual design aspects will be developed and adapted to the intended automated use in the HOLISHIP integrated design platforms.
  • Software Integration: of s/w tools developed in Cluster 1 to be integrated into HOLISHIP design platforms and the Virtual Vessel Framework.
  • Application Cases/Demonstrators: in which the integrated s/w platforms will be applied to the design and operation of ship and other maritime assets and the use and benefit of the developed frameworks will be demonstrated.

This overall project structure is sketched in 2 with a further detailing of the concept of the Application Case Cluster in the following 3.
