Floating Jetty Anchoring and Marine Mooring Systems
MoorTech is a Tasmanian-owned company offering a variety of marine services from surveys to diving platform services.
As part of this offering, MoorTech introduces the N-Viro Mooring & Anchor System, which brings a unique and innovative development to the marine and aquaculture industry.
For most people, environmental awareness of the marine environment is based on visual impact at the surface.
At MoorTech we believe there is also a case for environmental awareness and responsibility at the seabed.
History of screw piling
The MoorTech/N-Viro system is based on screw pile technology which were first used in the 1830’s by Alexander Mitchell for foundations of lighthouses in tidal regions around the Thames Estuary and other parts of England.
Screw pile technology came to Australia in 1872 and used on the Cape Jaffa Lighthouse (Sth Australia). The oldest known screw pile structure still operating in Australia is the Victor Harbour Jetty, (sth Aust) known as “the screw pile jetty”, built in 1881.
In Tasmania, the New Norfolk bridge, built in the early 1900’s was founded on screw piles; this was replaced by the present structure in the 1980’s.
