Offshore Wind and Energy Storage are two of our primary focus areas in renewable energy. We cover development through to execution.
Renewable Technologies - how we can help
|
Renewable Energies cover a broad spectrum of technologies, each with its own challenges, advantages and disadvantages. Furthermore, the technology adopted will also depend on the geographical and geological conditions pertinent to the site. In the last few years, there have been considerable technology advancements in the form of hydropower, wind and solar.
Although our skills and experience in Electrical, Instrumentation and Communications are relevant to all technologies, our primary focus is on Offshore Wind Power. This includes the Wind Turbines, Collector Stations, Subsea cables and Onshore Substation. |

Offshore Wind Power
|
Offshore wind technologies have been consistent and rapid. There has been much innovation with locating windmills in deeper waters, where it is not possible to use fixed structures. In these cases, there has been a move towards three principle technologies:
Massachusetts Institute of Technology (MIT) have been investigating TLPs for wind turbine since 2006 and before. Blue-H Technologies of the Netherlands deployed the first floating wind turbine on a TLP. |

Windfarm Electrical Systems Engineering
|
In the case that the farm is typically within 60km from shore and export power is high voltage AC, then the ESPs would typically include the MV/HV Export Transformer.
In the case the farm is located further than 60km from shore, the export power would typically consider High Voltage DC, and the ESPs would include the AC/DC Conversion equipment. Our focus is on "Balance of Plant" The balance of plant includes all the components of the wind farm except the turbines, including transmission assets built as a direct result of the wind farm. |

Offshore Wind Substations
Offshore substations are the heart of the offshore windfarm. The collect all the power from the individual wind turbines and transmit this power to shore.
Our experience in this area includes studies, design engineering, procurement and installation activities related to the scopes of:
|
Racebank
Sandbank
|
Electrical Service Platforms and Converter Stations
|
ESPs and Converter Stations are very similar to eHouses used on other offshore installations. More about our experience can be found in Marine and Offshore
The outfitting of these buildings can be viewed in two parts:
Primary electrical system The primary electrical system for a large 400MW to 800MW wind farm comprises the following main components:
Building and Auxiliary Services. he ESP building (offshore) and in a similar fashion, the onshore substation building will have the following services provided;
|
HV Modular substation, comprising Instrument Room, Control Room, and HV Gas Insulated Switchgear.
