Offshore Solutions Group
Developing multiple wet storage facilities - known as FLOW-Parks™ - to optimise logistics, manage risk and enable delivery of the UK's floating offshore wind ambitions.
What we deliver
OSG's multi-disciplined, international team uses highly developed and proprietary processes, systems and software to develop multiple wet storage locations around the UK. Our FLOW-Parks™ uniquely provide floating-wind exclusive wet storage capacity and capability to UK port and construction yards and global suppliers of FLOW foundations.
01 / 03
Advice for FLOW project owners, developers, port operators on wet storage requirements, site suitability and operational planning. Support to EPC(I), T&I, technical, commercial and financial specialists on wet storage requirements within integrated logistics planning including interface management, commercial contracting and operational delivery.
02 / 03
Providing full lifecycle FLOW-Park™ development - consenting, licensing, construction, operation and decommissioning - from initial survey through to operational readiness.
03 / 03
OSG work with local partners to assess and deliver FLOW-Park™ wet storage opportunities across the UK and internationally.
What is a FLOW-Park™?
Floating wind assets are large (c. 100m x 100m, approximately 6,000 tonnes), unmanned, and have no marine propulsion. During construction, they must be marshalled and stored safely in a designated offshore location - wet storage - before being integrated with their towers and turbines and installed offshore.
A FLOW-Park™ is a carefully selected, assessed and operationally configured offshore location with pre-installed moorings, anchors and a full suite of safety and monitoring systems. It is the enabling infrastructure for the UK's floating wind ambition.
100m x 100m each base (foundation)
Floating wind foundations weigh approximately 6,000 tonnes, are unmanned and have no marine propulsion. They require temporary seasonal storage during the construction process.
Pre-installed systems
Pre-installed moorings and specialised safety and security systems. No rigid structures in the water. Re-use of existing marine anchorage areas. Sensitive to the local environment and other users of the sea.
24/7/365 manned
Live 24/7/365 environment, asset and vessel management from a local, manned operations base.
Development lifecycle
Site identification, desktop studies, early stakeholder engagement and Crown Estate seabed exclusivity agreements. Agreements covering access, operations and the seabed.
Geophysical surveys, EIA Scoping, Environmental Impact Assessment, Habitats Regulations Appraisal and consultation programme.
FLOW-Park™
Wet Storage
Procurement, installation of mooring systems, anchors, monitoring infrastructure and operational readiness.
24/7/365 staffed operations with FLOW-Monitor units, satellite, cellular and radio communications on each asset within a specialised Management & Control System.
Active projects
SW England / Celtic Sea
The Celtic Sea FLOW-Park is under early evaluation as a facility to provide critical infrastructure support to the region's ports and harbours and their ambitions for floating wind development across the Celtic Sea. An initial site suitability assessment has been completed and a 3-year exclusivity agreement signed with a major regional port to facilitate more detailed site-specific assessment and early stakeholder engagement prior to a more formalised development process.
Moray Firth, Scotland
The Moray FLOW-Park has been undergoing technical evaluation, environmental planning, extensive stakeholder consultations and site investigation activities and is close to finalising an initial development plan that is both fit-for-purpose and minimises the potential impact on other users of the sea and the wider environment. These efforts are illustrated by the completion of a comprehensive and wide-ranging Scoping Report as part of a full Environmental Impact Assessment programme of activities that goes beyond the minimum statutory requirements and reflects the unique first-of-a kind nature of the Moray FLOW-Park.
The policy context
Wet storage has been formally recognised at the highest levels of government and industry as essential to delivering the UK's floating offshore wind ambitions.
UK Government
The UK Government's Department of Energy Security and Net Zero (DESNZ) has specifically recognised wet storage as a qualifying investment for the Clean Industry Bonus under CfD Allocation Round 7.
Scottish Government / SOWEC
The Scottish Offshore Wind Energy Council (SOWEC) Strategic Investment Model (SIM) recognises OSG as strategically important to Scotland's offshore wind industry, specifically for temporary offshore storage of floating wind assets.
Renewable UK
The Renewable UK FLOW Taskforce Industry Roadmap 2040 specifically notes the wet storage need for UK floating wind projects and port operations as a sector-wide requirement.
