Concept Design

Based on a deep understanding of current technology and future development trends, we are able to develop and evaluate innovative and cost-effective design concepts. Working with our clients we undertake concept design studies including review of:

• Commercial, technical and environmental requirements
• Device configuration, dimensions and rating
• Rotor and power train solutions
• Control and safety systems
• Power take-off
• Foundation, support structure and moorings

Mechanical design

We offer a full range of mechanical and structural design services to developers of marine energy devices.

• We provide leading edge design analysis of complex structural components involving bearings, gears and bolts.
• We use rigorous, rapid methods to analyse castings, forgings and welded structures.
• Our engineers undertake the design of components and systems from concept, through detailed analysis, to design documentation, specifications and certification reports.

Electrical System Design

Garrad Hassan has extensive experience of the design offshore electrical systems. Our design service includes all critical issues:

• Load-flow studies
• Fault and protection coordination
• Power quality calculations
• Design for optimum lifetime costs
• Marinisation

We are also able to provide detailed design assistance with:

• Medium and low voltage electrical systems
• Earthing and grounding systems
• Cables
• Transformers and switchgear
• SCADA system cabling

Control Systems Development

We are industry leaders in the design of turbine control systems and development of classical and modern multivariable control algorithms.

Our expertise includes advanced control algorithms for the alleviation of turbine structural loads and optimisation of energy capture.

We offer hardware implementation, testing and on-site commissioning of turbine controllers.

Real time control testing can be carried out using our purpose built facility based on interfacing the turbine controller to a GH Tidal Bladed simulation of the device.
