When it comes to offshore mooring, choosing the right system is crucial for safety, efficiency, and long-term durability. This guide explains the key differences between single- and multi-point mooring buoys, their typical applications, and how to select the right mooring buoy system for your marine environment.

What is Single Point Mooring (SPM)?

A single-point mooring (SPM) system is a floating buoy or structure anchored to the seabed with a single mooring connection. It allows vessels to moor and rotate freely around the buoy, accommodating changing wind and current directions.

Features:

1) The buoy can rotate on the water surface with waves or wind (with a certain degree of freedom)

2) Simple installation structure

3) Easy to deploy and recover

What is Multi-Point Mooring (MPM)?

A multi-point mooring system uses two or more mooring lines connected to anchors at different angles, offering higher positional stability for fixed platforms or large floating structures.

Features:

1) Redundant anchoring for increased safety

2) Holds the buoy or vessel in a fixed position

3) Ideal for high-current or deep-sea conditions

Choosing the Right Mooring System

When selecting between single-point mooring systems and multi-point mooring, consider:

- Water depth and current strength

- Vessel size and operation frequency

- Buoy type (PE, metal, composite)

- Port or offshore facility requirements
