Mooring Buoy

A Mooring Buoy system consists of multiple steel buoys. The exact configuration depends on water depth, field requirements and environmental conditions. Typically it is a pattern of four to eight mooring points used to moor tankers. Each point consists of a rigid buoy moored to the seabed by a chain and an anchor. The prime purpose of each buoy is to act as an anchoring point for the tanker to berth. The buoys are moored to the seabed, therefore, the tanker berths without use of its own anchors.
Each buoy has a chain hawser assembly through the centre of the buoy unit, terminating in a chainstopper on deck. The buoys are normally fitted with double quick release hooks to disconnect quickly from the tanker. Hawsers are connected to the bow or stern of the tanker on one end and to the quick release hook of the buoy on the other end.
After mooring to the buoys, the tanker may start (off)loading by connecting a subsea hose string to the ships manifold. The other end of the hose string connects to the PipeLine End Manifold (PLEM), fixed to the seabed or any other pipeline transferring the product to or from any installation located onshore or offshore. Should the tanker leave the berth, the hose string will be laid down on the seabed, to be picked up again when the next tanker arrives.


Anchor arrangement - An anchor arrangement is deployed to connect the buoy to the seabed. For each buoy, dynamic behaviour calcultions predict the behaviour of the buoy for various wind, wave and current conditions. These calculations determine the optimum anchor leg arrangement, and the size of the various anchor leg components.


Basic anchor leg components are:

1、Anchors or piles, depending on the soil data, to connect the anchor legs to the seabed

2、Anchor chain
3、Chainstoppers to connect the chain to the buoy

  • Mooring Buoy A Mooring Buoy system consists of multiple steel buoys. The exact configuration depends on water depth, field requirements and environmental conditions. Typically it is a pattern of four to eight mooring points used to moor tankers. Each point consists of a rigid buoy moored to the seabed by a chain and an anchor. The prime purpose of each buoy is to act as an anchoring point for the tanker to berth. The buoys are moored to the seabed, therefore, the tanker berths without use of its own anchors.

  • Polyethylene Foam Mooring Buoy Mooring Buoy is available in different shapes, such as cylindrical, barrel, peg-top or custom design. Mooring buoys are used for inland waterways and offshore applications. It is constructed by resilient closed cell polyethylene or EVA foam around the inner central steelwork, covered by polyuretane outer skin. The polyethylene foam core make the mooring buoy unsinkable even in case of damage.

  • Cylindrical Mooring Buoy Cylindrical buoys, chain-through buoys, pick-up buoys are the three main types of support buoys, which are used extensively in the single point mooring system. Mooring bouys are made of composite materials including polyurea elastomer material, PE high elastic foam and steel. We supply all types of mooring buoys and other marine equipment.

  • Floating Mooring Buoy Mooring buoys are an important mooring facility for ship mooring. It is cylindrical shaped mooring equipment that floats on the surface and connects anchor on the bottom of water with anchor chains. Mooring buoy consists of mooring ring, buoy body, anchor chains and anchor. Mooring ring is used to join the ship cables and transfer the mooring force to the steel ring of the anchor chains. Mooring rings has two forms: flat type mooring ring and insert type mooring ring.

  • Foam filled mooring buoy is made of steel and closed cell foam. This unsinkable construction can withstand the toughest mooring application and environment. We provide services of design, production and sample processing of mooring buoys. If you want to know more about our products, please feel free to contact us.

  • UHMWPE mooring buoy is made of ultra high molecular weight polyethylene material whose molecular weight is more than 2.5millions and its chemical structure is saturated molecules. This type of mooring buoy works much better than polyethylene modular buoy and steel buoy. It is maintenance free and has long-term service life.

  • Marine Steel Floating Mooring Buoy Mooring buoys are used for ship mooring to recharge, shelter,degauss, standby etc.. It is an important cylindrical floating mooring facility for ship berthing.

  • Steel mooring buoy is widely used for ship’s anchorage mooring. It floats on the surface and connects the anchor at the bottom of water with anchor chains. Ships can do the following operations when park: recharging, sheltering, degaussing or standby etc..
