Marine platform design

This joint project between instream energy systems and it power consulting will complete a second generation platform design for the deployment of instream's multi-turbine array hydrokinetic system for marine applications.

This project will support the development of Instream’s pre-commercial multi-turbine array hydrokinetic system for marine applications by completing the preliminary repeating unit size turbine platform design, the turbine deployment unit (TDU). This project further aims to produce a design framework and associated design software tools to enable the design of similar floating marine energy devices. Instream and ITP will develop a standardized replicable flotation platform that can be deployed in marine and targeted inland environments for future revenue generating commercial projects. Instream’s product development road-map includes proposed system enhancements to transition from a technology demonstration technology readiness level to a commercially representative system. The proposed project is a component of Instream broader turbine system commercialization program which is being implemented through a multi-generational development strategy, with each generation of the product achieving specific milestones for overall performance and cost. Each phase of turbine development is intended to open up new market opportunities as per Instream’s market rollout strategy. ITP intends to market the design tools and increase know-how to attract new market opportunities. Preliminary Gen 2 development, design and architecture of the platform includes but is not limited to: • Base unit structure design (define approach to deployment system modularity and deployment, design Turbine Deployment Unit [TDU: a collection of turbines on a single structure], design platform for marine environment, design for 3rd party manufacture.) • Unit Grouping (Identify optimal number of turbines per TDU deployment structure, Identify optimal number of TDU groupings per turbine block, design group structure with allowances for configurability.) • Mooring (develop mooring approach for multi-turbine configuration and deployment structure base units, consider universal structure for multiple applications.) • Deployment and service (develop deployment and service strategy and guidelines for 3rd parties, create reference designs and application / installation guides.) Preliminary definition of the Gen 2 system design considers a multi-turbine platform as a single deployment unit, which can be aggregated to higher power scales with shared power conversion infrastructure to reduce costs. This collection of deployment units can be replicated along a waterway and connected to the grid via a common feeder. This multi-level scalability will reduce cost through: • Commoditization of base unit as system ‘building block”, • Standardization of platforms and deployment solutions, and • Standardization of power conversion and grid-tie electronics. The Gen 2 design phase represents a significant step in the commercialization of a productized power generation system. This step requires an architectural shift that will be fundamental to the realization of the overall product strategy of employing multiple smaller turbines in aggregate for utility scale deployments. The Gen 2 phase will result in the identification of the optimum scale and architecture for, and design of multi-unit floating turbine deployment unit (TDU) platforms.
