The primary aspect of the single point mooring (SPM) offshore operation is a special loading buoy that’s anchored offshore. This buoy is designed to allow vessels to easily moor alongside for the efficient transfer of liquid freight, such as petroleum.

  • Location : Single point moorings are most useful in areas where dedicated offshore facilities aren’t available for the regular loading and unloading of cargo. For example, a SPM might be anchored several miles from an onshore base
  • facility : A series of sub-sea pipelines then connects the base facility with the SPM. The benefits of this offshore connection include the ability to facilitate extra large vessels with high drafts, as well as saving on the time otherwise spent for ships to navigate an inlet and dock for traditional loading and offloading.
  • Mooring arrangement : Single point moorings are secured to the sea floor through a series of anchors, anchor chains, chain stoppers, and other ground tackle components. The anchor point secures to the sea floor, which connects to the anchor chains, which then connects to the buoy itself. The anchor points are set up according to the unique sea and wind conditions of the location. Once properly moored, the SPM is capable of moving freely within a set limits according to the wind, current, waves, and other extraneous factors such as the ship conditions.
