Do you know what a mooring buoy is in the marine environment? Mooring buoys are quite essential for offshore and port operations. In this article, you will gain a complete understanding of mooring buoys — what they are, how they work, and why they are essential for maritime operations.
Mooring buoys are critical tools in maritime operations, providing safe and secure anchoring points for vessels in harbors, ports, and offshore locations. Unlike navigation buoys, which guide vessels, mooring buoys are designed for vessels to tie up to, eliminating the need for dropping anchors directly on the seabed and reducing environmental impact.
A mooring buoy is a floating device used to secure a vessel at a fixed location. Vessels connect to the buoy via ropes or chains, which are attached to a submerged anchor or chain system on the seabed.
Key functions:
Provide safe anchorage without dropping the vessel’s anchor.
Protect sensitive seabed environments like coral reefs or pipelines.
Maintain vessel position even under changing tides and currents.
1) Anchoring System
-- Mooring buoys are connected to heavy anchors or chain systems on the seabed.
-- The buoy floats on the surface, while the anchor keeps it in a fixed location.
2) Vessel Connection
-- Boats tie their lines to the buoy’s eyebolts or rings.
-- This system distributes tension, allowing vessels to move safely through waves and wind.
3) Stability Features
-- Many mooring buoys are equipped with chain passages, protective sleeves, and high-visibility markers to withstand harsh marine conditions.
| Type | Purpose | Features |
|---|---|---|
| Single Point Mooring (SPM) Buoy | Anchors a vessel at a single fixed location | Rotationally molded polyethylene or steel, chain passage, high visibility |
| Multi-Point Mooring (MPM) Buoy | Holds a vessel with multiple anchor points | Larger structure, multiple chain attachments, often used offshore |
| Port/Harbor Mooring Buoy | Temporary or long-term docking | May include fenders, light markers, or protective sleeves |
Commercial Ports & Harbors – Secure cargo ships and ferries safely.
Offshore Projects – Anchor floating platforms, dredgers, and oil/gas vessels.
Environmental Protection – Prevent anchor damage to sensitive seabeds.
Leisure & Marina Operations – Tie-up points for yachts and small boats.
