Projects

EMEC are investigating options for deployment of a floating subsystem test platform (FSTP) for use by floating offshore wind technology developers. The scale-platform would enable at sea testing of a range of novel subsystem components such as monitoring equipment, mooring technologies, new materials, and many more.

​

Quoceant developed a Design Basis document for the FSTP to inform onward development. The work carried out with support from First Marine Solutions included OrcaFlex modelling to help inform the platform design choices, targeted user-engagement, pre-FEED to set-out the platfrom configuration and, finally, compilation of a Design Basis document setting out; design principals, site and environmental conditions, high-level functional requirements and applicable codes and standards for onward design. 

Quoceant recently undertook a package of work to analyse the hydrodynamics of long tethers for multi-data collection autonomous underwater vehicles (AUVs) in deep water. The project was completed using OrcaFlex to simulate the effect of different tether lengths, and speeds, and investigated working assumptions to support 3D at Depth's ongoing technology development and operational activity.

Marine Power Systems (MPS) are developers of a flexible modular technology intended for the deployment of floating offshore wind at an industrial scale. Quoceant have been providing engineering support to MPS including input into the platform design and offshore installation systems. Our services have included a mixture of review, design, analysis, and simulation modelling work.

Quoceant have been contracted by thermal energy storage innovators, SynchroStor. Quoceant will work closely with SynchroStor engineers to develop a state-of-the-art physics and control whole-system model along with detailed models of the novel subsystems required to compress and expand a working fluid and transfer heat to and from the storage media. 

​

SynchorStor are developing a patented Pumped Thermal Energy Storage (PTES) system aimed at meeting the changing needs of the grid system as it transitions to greener sources of energy generation

Quoceant have been contracted by Ocean Winds to provide engineering support to the design of the Moray West offshore wind project to be built of the coast off Scotland, in the Moray Firth. The team at Quoceant are working with Ocean Winds on the design of temporary steel work structures for installation of the wind turbines and to provide general, third-party engineering support and analysis to the substructures for the 14.7MW wind turbines. Ocean Winds was created as a 50-50 joint venture in 2020 by EDP Renewables and ENGIE.

​

The work comes on the back of Quoceant's previous support to Moray East Offshore Wind Farm which commenced its first power export in June 2021. Moray West is aiming for first power export in 2024 and will be 882MW in capacity.

Quoceant were contracted by Minesto to design a subsea quick connection system for use on their tidal kite technology. The design solution provides dual mechanical and electrical connection between the kite system and its bottom mounted foundation and subsea cable. Working alongside marine operations specialists, Inyanga Maritime, Quoceant took this project from concept through detailed design, procurement, qualification testing, build and operational support. The delivered subsea connection system is capable of repeated connection and disconnection operations, enabling recovery of the kite technology as desired for inspection and maintenance. Operation is quick and requires no diver interaction allowing the marine operations to be completed within short weather windows.

Quoceant were contracted to provide structural engineering support of the foundation design of the 'Moray East' offshore wind turbines and offshore substations. Moray East is a 950MW wind farm located around 20km off the coast in the Outer Moray Firth, it will be Scotland's biggest offshore wind farm. Quoceant provided client-side expert engineering review services for the project developer, and advice in support of the substructure design, including review of the foundation design, grout interfaces, and fabrication process.

The 'Q-Connect' is a quick connection system being developed by Quoceant to provide combined mechanical and electrical connection to connect a marine renewable device to its mooring and subsea electrical infrastructure.  The 'Q-Connect' is being designed to be adaptable to a range of different marine applications. The project has received funding from Wave Energy Scotland as part of their Quick Connection System development programme. The project is now nearing completion of stage 3 of this programme which includes qualification testing.

​

During the development process, Quoceant are working with project sub-contractors, EMEC, SMD and Inyanga Maritime to progress engineering design and commercial understanding. The long-term vision is to develop a product that has market appeal to a range of marine developers by satisfying their connection needs and being compatible with array scale deployments.

Quoceant have been awarded a stage 1 contract to support the design of Marine Power Systems (MPS)'s power take-off system.  

MPS are a Welsh-based marine energy company developing the WaveSub wave energy device, and the DualSub technology that can simultaneously capture both wave and wind energy in a single machine – at large scale.

Quoceant provided design support to AWS Ocean during their Wave Energy Scotland funded project to demonstrate their Waveswing technology. Quoceant’s involvement spanned all three stages of the project from feasibility assessment through concept optimisation and on to detailed design and demonstration. Quoceant led on aspects of the engineering and concept development work, FEED, and supported the risk and technical assessment activities. Our work has included a range input across PTO, environmental control, structural hull design, and availability analysis.

Building on Orbital’s SR2000, earlier generation machine, Quoceant worked with Orbital Marine Power to invent and develop new features to allow access to nacelles for maintenance and to reduce the cost of structures. A range of concept options were developed by Quoceant, supported by preliminary analysis and engineered costings, to allow selection for onward development and detailed design of the O2 machine by Orbital.

Quoceant are partnered with Artemis Intelligent Power in an innovative project to develop a hydraulic power take-off system, called ‘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.

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.

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.​

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.

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.

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.

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.

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 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.

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.

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.
