Genuinely sustainable development will inevitably be economically successful. We are aware of our responsibilities in the locations where we work and are passionate about the creation of sustainable employment and training opportunities for local people.

Benefiting the Local Economy

We advocate a sustainable procurement approach and believe that, wherever possible, this should include using a local supply chain. We feel this adds value to our business as well as to the local economy, and we build it into our advice to clients as we offer the best practical, economic and environmental options when we procure on their behalf.

Ocean Resource Renewables' self installing foundations have a number of environmental advantages over the whole life of the foundation, not just in the design or installation.  In the offshore wind market, this attribute supports the key reason for using wind turbines to reduce emissions and provide clean energy.

In Manufacture

The superstructure of SeaBreeze™ is a concrete fabrication.  Whilst CO2 is produced in the manufacture of cement, concrete during its life absorbs CO2. The airborne pollutant levels from a concrete plant are much lower than those from a steel plant and the long term impact on the land on which it is based is lower than for a steel plant.

One study based on the use of the ATHENA™ software suggests that for similar strength structures, concrete energy cost is ½ that of a steel structure (ref How Sustainable is Concrete - Leslie Struble and Jonathan Godfrey, University of Illinois at Urbana-Champaign, USA)

Low Noise Installation

In recent times, the UK Department for Energy and Climate Change has highlighted the negative impact piling has towards dolphins e.g. masking of their audio communication signals and extended noise emissions resulting from the piling.

Our gravity foundations have a very low audio footprint and therefore has no significant impact on sea mammals.  The only noise is generated from the flooding of the buoyancy tanks, a natural water noise, and this is limited to approximately a 3 hour period of installation.

Low Emission Installation Vessels

An installation round trip is expected to take 6-12 hours (dependent on distance from port to wind farm location).  Note that by using basic ocean-going tugs, the CO2 emissions are reduced during installation to an estimated 1/10th of the output from a large North Sea assembly / installation vessel.

There are much fewer vessel hours required too since the SeaBreeze™ installation is a one-trip activity whereas piling and offshore assembly requires vessels to be on station offshore for weeks and months during installation for assembly and shuttling components to site.

Operation and Maintenance

Concrete is well known as a stable low maintenance material in marine environments.  In addition it continues to absorb CO2 as stated above.  Since little maintenance is required, unlike steel marine structures, this minimises offshore time for O&M vessels and the CO2 emissions from them.
