Our Projects: From small to big we add value, experience and innovation to all projects.

Power Take-Off Development

Artemis Intelligent Power

Quoceant are partnered with Artemis Intelligent Power in an innovative project to develop a hydraulic power take-off system, termed ‘Quantor’.  The project has received £2.5m of funding from Wave Energy Scotland as part of their stage 3 programme and will see the concept demonstrated at full-scale on a unique laboratory test-rig.  The rig will simulate the behaviour of a wave energy converter responding to a range of different real sea conditions.

 

The fundamental Quantor concept is both scalable and adaptable to many different proposed wave energy converters. It may also be applied to challenging controlled force and motion applications in the offshore oil and gas industry and wider afield.

Cable Management System Design

Andritz Hydro Hammerfest

Quoceant were contracted by Andritz Hydro Hammerfest to provide engineering design, analysis services and procurement support in relation to their cable management and subsea connection system for the Meygen project in the Pentland Firth.  Our work has included; mechanical and electrical engineering design, through to system prototyping, piloting, assembly and procurement support.

"Quoceant provided engineering design services in relation to our turbine development for the flagship Meygen project.  We have been very impressed with Quoceant's input and expertise." - Craig Love, Engineering Manager, Andritz Hydro Hammerfest

Structural Analysis of Ocean Basin Wave Tank

Edinburgh Designs Limited

Edinburgh Designs Ltd contracted Quoceant to undertake analysis of a novel moveable floor structure for use in a new-build ocean basin wave tank. The work covered both traditional structural analysis of the structure using finite element methods and fluid-structure interaction simulation using both Coupled Eulerian-Lagrangian and Smoothed Particle Hydrodynamic methods to examine the affect of wave action on the floor structure at shallow water depths.

The project included analysis and comparison of existing and concept floor structural segments and layouts during wave-induced variable pressure loading for strength and deflection, design of floor components, assessment of natural vibrational mode shapes of the floor structure and assessment of floor behaviour during temporary operating states.

Marine Operations Concept Design

Tension Technology International (TTI)

Quoceant provided marine operations planning support to Tension Technology International as part of the concept development stage of a novel marine energy development project.  The work included; story boarding, estimation of weather waiting, availability analysis and costing of deployment and removal operations.

"The Quoceant team bring their real-world experience and ingenuity to bear on the challenge of deploying and maintaining novel technology at sea. We were very happy with their work." - Ben Yates, Consultant & Director, Tension Technology Intenational Marine Renewables

 

Advanced Concrete Materials

Wave Energy Scotland

Wave Energy Scotland have awarded a team lead by Quoceant a contract as part of their 3rd Innovation call which targets development of alternative materials and manufacturing processes for use in the wave energy sector.  The cutting-edge project will focus on the use of advanced concrete engineering.  Quoceant will lead the work with partners Dundee University and consortium members, Black and Veatch, Innosea and David Kerr Engineering.

 

Concrete is fundamentally well suited to wave energy applications.  However, many wave energy designs are demanding for conventional concrete approaches due to high point loads, the requirement to remain water tight, and the potential impacts of salt water on conventional reinforcement materials.  This project will investigate new concrete technologies and manufacturing processes to overcome these challenges and offer wave energy developers the opportunity to significantly lower costs.

Control Landscaping Study

Wave Energy Scotland

Quoceant, working with the Offshore Renewable Energy (ORE) Catapult and Sgurr Energy, successfully undertook a landscaping study focusing on control systems for wave energy convertors on behalf of Wave Energy Scotland (WES).   Quoceant are world-leading experts in the control of wave energy systems our engineers having previously led the development of the control system and novel hydraulic power-take-off concept successfully demonstrated in the Pelamis Wave Power converter.

 

Commissioned in March 2016, the overarching control landscaping study is aimed at helping identify the control requirements of wave energy converters, thus enabling targeted technology development and innovation.

Mooring Analysis and Reuse Options

European Marine Energy Center (EMEC)

Quoceant were contracted by the European Marine Energy Center (EMEC) to undertake a review of a mooring system deployed at the wave test site with a view to inform potential developers of its characteristics.  This included review of previously undertaken failure mode effects analysis, static simulation of the mooring system to define general parameters, inspection considerations and high-level concept ideas for reuse of the moorings.

Fluid Power System Review

Orbital Marine Power (formally ScotRenewables)

Quoceant provided expert hydraulic systems knowledge to the review of the fluid power system for a leading tidal developer. The functionality and criticality of the design was considered in detail. Specific design modifications were recommended and the proposed commissioning procedures were reviewed to ensure safe and rigorous testing and that potential in-service risks were being addressed where possible. Quoceant provided a summary report detailing several observations and associated recommendations.

Third Party Technical Review

Black Rock Tidal Power

Quoceant were selected by Black Rock Tidal Power to provide third party engineering review in relation to their project in the Bay of Fundy, Canada.   The scope included technical review of the platform, maintenance methods and systems, sub-sea connection, survey work undertaken at the site and the reported seabed conditions.  A Failure Modes and Effects Analysis methodology was used to identify and highlight areas of greatest risk to survivability of the platform and to ensure the level of risk was acceptable to the client. 

Concept Development: Variable Hull

Wave Energy Scotland

Quoceant is developing a novel concept to enable a substantial change to a machines hull volume on command.  A selectable hull volume change would allow a wave energy converter to grow substantially to absorb much more power during most of the year, while reverting to a smaller, robustly survivable form in storm conditions.  The idea being developed as part of a Wave Energy Scotland (WES) R&D contract, will design a system capable of automatic inflation and deflation and which is stowable to allow multiple uses.

 

The project includes concept design, analysis, tank testing and cost of energy review.  Read more on our blog.  The stage 1 report is available from Wave Energy Scotland's Library.

Offshore Operations Review

EMEC

Quoceant were contracted by EMEC to provide expert review and advice in relation to planned offshore operations to remove an obsolete mooring system from the wave test site in Orkney.  The operations took place off the coast of Orkney in approximately 50m of water depth and involved removal of a large subsea buoyancy unit, chain and anchoring system.
