Designing and Building Single Point Mooring Systems
Our News Update
The MONOBUOY company was set up in 1998 to provide multi-disciplined engineering, project management and construction services to oil and gas companies throughout the world.
Our staff has accumulated well over 50 years experience in the fields of offshore offloading terminals.
We design, build and install CALM Buoys, FSO's and FPSO's.
We also overhaul CALM buoys and often have used refurbished buoys for sale.
In addition we support terminal operators by supplying spare parts, engineering and consultancy services.
The two buoys have been completed and are awaiting their onward transportation by heavy lift vessel to Libya. The buoy design and
subsequent fabrication were followed by ABS who have now issued their final design review letter and survey report.
delivery of these two buoys to the exacting standards set by ABS marks a major milestone for Monobuoy. We will now take this experience
and continue discussions with our growing list of potential clients that are looking for more cost effective options for their CALM
Itís a tough time with oil prices around the 50 dollar mark and we can offer proven, innovative and cost effective
solutions backed by our demonstrable ability to meet the standards set by international Class Societies.
