Monopiles, composed of steel pipes, are the most widely utilized foundations for
offshore wind turbines. Anchored by pile legs driven into the seabed, these structures
provide secure stability. The upper part of the monopile is connected to the
wind turbine tower through flanges and bolts, making it particularly suitable for
nearshore and shallow water areas.
The transition piece (TP) is a tubular structure made out of high-grade
offshore steel. The TP is the second part of a wind turbine generator
(WTG), which is directly connected to the monopile foundation and the
WTG tower. The most common connection of a TP is with flanges or a
grouted connection.
The wind tower plays a supporting role in the wind turbine and absorbs the
vibration of the unit. Daiin Heavy lndustries is among the worlds' largest suppliers of
wind towers, with 20 years of production experience in tower manufacturing.
A jacket is an infrastructure used for offshore oil exploration and
development operations. It is a Space frame composed of hollow legs
(conduits) and vertical and horizontal bars connecting the legs.
In recent years we have seen the development of a new foundation concept
being the TP-less solutions in which the WTG tower is connected directly to
the monopile. This product maxmum weight 5000-8000 tons. With high
transportation requirements, Dajin Heavy Industry is exploring the process
to manufacture fleating foundations, and is equipped with a
professional international transportation fleet.
