The Greenstick Innovation
Greenstick technology offers a brand new solution
for a wide range of applications that require
mooring in water.
The Greenstick is a helical pile or suction pile with
a patented* lockable and unlockable joint,
allowing vertical deployment at sea, in depth, and
the ability to configure to a support angle of 45
degrees +/-, as required, once the Greenstick has
been secured to the sea or ocean floor.
No other deployment system offers this
capability, making Greenstick technology
unique.
Depending on the size of the Greenstick and the
installation zone, there are various methods of
locking and unlocking the joint which are covered in
the Greenstick patent, such as manual, electronic
and hydraulic.
Locking sleeve
Linkage not to scale
Shaft
Universal joint
Rotating arm
Screw blade
Patented lockable & unlockable joint
* UK Patent granted Dec 2013. International Patents for Australia, Canada,
Japan and South Korea also granted (Europe and U.S.A., pending).
In contrast to other anchoring systems, its innovative design allows the 360◦
rotating arm to be locked via a sleeve on deployment, unlocked when the
Greenstick is in position and configured according to requirements.
According to the patent [1], Greenstick piles can be of different types and
immersed in different ways; screw, driven, suction etc. This allows the
Greenstick pile to achieve the bearing capacity on horizontal loads of tens of
tons, enabling the technology to be used in many different applications.
