Wind energy as a power source is
favored as an alternative to fossil fuels, as it is plentiful, renewable,
widely distributed, clean and produces lower greenhouses gas
emissions.
Offshore
wind farms are often preferred over onshore farms. In that case, each turbine’s
tower rests on a pile foundation, usually a mono pile or a tripod. During
installation of the upper part, the tower is positioned over or in the pile.
The space between tower and the pile is sealed by a rubber seal. On top of the
seal grout is injected in order to make a solid connection. This construction
method secures the perfect vertical position of the tower. Because of the
application the seal is called a grout seal. Trelleborg Engineered Products is
specialized in the design and supply of active (inflatable seal) and
passive (lip seal) grout seals. With the increasing size of the power
substations, a float over process is increasingly used. In the floatover
process, a topside structure is installed onto an in-situ base structure (e.g.
jacket). Our Leg Mating Units are a critical part in this mating
process.
