Spread
Mooring System
Spread moored systems are mooring systems that allow
tankers to moor at a fixed location at a fixed heading and allows tankers
to (off)load their products. The main difference between this system and
buoy moorings, turret moorings and tower moorings, is that the mooring and
product transfer functions of the Spread Moored system are not integrated.
They are completely separated
Conventional
Buoy Mooring (CBM) or Multiple Buoy Mooring (MBM) for temporary mooring
This
mooring system utilises a minimum of three buoys. The tanker moored to such
a system is restricted from weathervaning. A Conventional Buoy Mooring
(CBM), also called a Multi Buoy Mooring (MBM), is in fact, a spread moored
system. It is generally used in
areas where the environmental conditions are moderate and the frequency of
offloading operations is limited, or for projects where smaller tankers are
received.
Since
this system does not allow the tanker to weathervane, it can cause severe
operational limitations. It typically consists of the following main
components:
- Multiple mooring buoys
- Anchor arrangement
- PLEM with submersible
hose string
