Deep Ocean Buoys and Mooring Systems
 Recall
Buoy Systems
Makai
was contracted by Exxon, USA, to design, fabricate, and test a timed and
acoustic released recall buoy for Exxon's subsea production system. This 2,500
pound buoy of syntactic foam and aluminum was designed for 3,000' depths and its
capability proven in deep water offshore of the Makai Pier.
Boat Mooring
Makai
has designed a series of small boat moorings off Molokini Island for the State
of Hawaii. Makai has also developed a large 25 ton mooring for an Atlantis
submarine and support boat off Lahaina, Maui.
Deep 2-Point Mooring
Makai
designed and developed the deployment plan for a 2-point barge mooring in
1,300' depth off Honolulu, Hawaii. The mooring was used for a suspended OTEC
pipeline test and therefore the environmental loading on the mooring was quite
severe. The mooring was deployed and performed as required.
Fish Aggregation Devices
Fish
Aggregation Devices (FADs) are buoys which are moored in deep water, used to
attract fish, and to improve overall fishing.
Makai has designed 3 separate buoy systems and their moorings for the
State of Hawaii. These buoys are located in depths ranging from 2,400' to 6,000'
at 26 different sites. To date, the Fish Aggregation Buoy program of the State
of Hawaii has proved very successful and the Makai designed buoys and moorings
have been in use for many years.
Deep
Barge Moorings using HDPE Pipe
Makai
developed the mooring and pipe concept for Mini-OTEC which was the first
successfully operated at-sea OTEC plant. Makai supervised the installation
of this 3,000' deep mooring and cold water intake system.
Makai recently completed a conceptual design for a similar but much
larger system for India's National Institute of Ocean
Technology.
Mooring
for Simulated Submarine
Makai
developed a Mooring Analysis and Engineering Recommendations for a Simulated
Submarine Target to be installed off the coast of Marine Corps Base Hawaii
at Kaneohe during 2000. The buoyant 50' long, 8' wide simulator system will be
moored 60' below the surface in water of 130' depth.
