Use a open-loop pump system
Posted by Maarten Kanters to Equipment, 2009-10-27 14:26:47
A single pipe will transport seawater from each turbine base to the generator platform.
This makes the wind farm an open-loop system.
For conventional turbines, electricity is already generated in the nacelle. A system of gears and
a generator converts the power in the rotor shaft to electric power. The electricity is conducted
through a cable, along the base of the turbine support struct...
Two Bladed wind turbines

The current standard for onshore wind turbines is to have three blades. The main reason for this is that human spectators experience three blades as the more tranquil view. Offshore, where spectators do not have to be taken into account, the advantages of having two blades can be exploited.
Such advantages are:
- lower production costs
- easier to assemble
- higher rotational speed
Remove the generator from the nacelle

The transport of energy from the nacelle to the base will be done using a closed-loop
system of pumps and pipelines. This way the heavy generator in the nacelle can be removed. As a result installation, maintanance, etc. will become easier.
Wind energy will grow in the coming years

Even though there is crisis allover, OWE will keep growing. At least, that's what Benno van Dongen says. Benno is consultant at Roland Berger, a worldwide strategy consultancy.
Roland notices a couple of trends:
1. Smaller players will enter the market
2. Market share of the top 4 producers will therefore decline further so they have to keep on top of innovation.
Between 2011 and 2020 E...
Production line at port
Posted by Joyce van Heijzen to Installation, 2009-09-30 10:12:59
The expectations are that a lot of offshore wind turbine fields are going to be installed, why not start working together in the supply chain.
Starting a cooperation with a wind turbine manufacturer, foundation manufacturer and a port
will make it possible to start a production line at the port.
This will reduce the transport needed to get big structures to the port and will reduce producti...
