The aim is to scrutinize the idea of separating the cargo holding part from the sail-carrying system and at the same time identify the most promising related solutions and associated needs for detailed follow-up research and finally the development of commercially attractive shipping solutions for maritime cargo transportation in a zero emission world.
Scrutinize the idea of separating the cargo-holding part from the sail-carrying system
The investigation and development of new sailing ship concepts and its integration into the existing transportation processes based on the principal idea of separating the sail carrying system from the cargo holding part of the vessel. Special interest will be given to technical aspects seen from the ship building perspective, as well as logistic aspects, issues of safe transportation and handling of different kinds of cargo. Concerns of ship owners, as well as the demands of the ship’s crew, who in turn must handle this new kind of vessel in all weather conditions, will play a major role in early concept design phase.
Quantification of the Economic Potential
The key aspects of commercial vessels are their economical benefits that differ depending on the shipping route and the transported cargo. These critical parameters must be identified and investigated after close consultation with ship investors, owners and operators. The overall costs for the building of cargo sailing ships, the higher investment costs (including the higher interests) and the potential savings in operational costs during a lifetime operation using wind as the main energy source, must be thoroughly assessed for each design. The overall costs can then be compared to conventional engine driven shipping solutions in order to evaluate the benefit and ROI for a new generation of maritime transport powered by wind-propulsion technologies.
Outline of Ship Theoretical and Engine Solutions
Conventional merchant ships have difficulties to utilize sailing systems, because their hull-shape can not deal with the strong side forces induced by large wind sail systems. From a ship building perspective the aero- and hydrodynamic qualities of the concepts must be investigated in greater detail to balance the interplay between the aero- and hydrodynamic forces as well as to comply with hydrostatic, seakeeping and maneuvering requirements for the classification of the vessel concept. Moreover the engine-assistance has to be configured in line with the wind-propulsion system and the requirements for safety and classification. The results of those comparisons will clarify the benefits and disadvantages of the systems in question and will help to decide which system should be used for a specific cargo transportation task on a specific sea-route.
Define a Route to Classification for Secure and Safe Operation
The concept must be technically secure and comply with classification rules.
