Mooring System
The weaknesses of the traditional Steel Mooring / Navigation Buoys are rusty, worn out, and sharing of pulling forces among the Buoys’ cylindrical structures. In the case of ageing or collision, especially the Private Mooring Buoys, it may be creaked, holed, sunk, or even pulled apart during a heavy storm.
EVA-Polyurea Mooring Buoys
With the availability of new materials and high technology supports nowadays, we develop Non-metal Mooring Buoys that are either made in high-density Ethylene-Vinyl Acetate (EVA) completed with an all-in-one stainless steel middle shaft with top & bottom mooring rings, then thoroughly sprayed with 5–8 mm thick of Polyurea for watertight, maintenance-free and long-lasting; or used the Fiberglass (GRP) Through Chain Module filled with rigid Polyurethane (PU) and fitted with the Reinforced Rubber Fender.
Polyurea is a newly developed material applied by spraying with a Computerized Spraying System. It is a very high abrasive, heat resistant, maintenance-free and long-lasting fabric; it can be mixed with the desired colour and dry immediately upon spraying.
The idea of the Non-metal Mooring Buoys is to remove the stress (pulling forces) from the cylindrical body of the Mooring Buoy; thus, all the pulling forces will be sustained by the Middle Shaft or the Mooring Chain directly, the Mooring Buoy itself only acts as a floatation unit to support the weight of the Mooring Chain and maintains 1/3 – 1/2 stay afloat on the surface as required.
Despite the weight and size of an EVA Mooring Buoy being much less than a Steel Mooring Buoy under the same buoyancy requirement, it is more long-lasting (10 years or more) and maintenance-free for long-term operation. In the case of collision, the soft, lightweight and highly abrasive EVA material will significantly reduce the impact forces and cause no damage to the Boat and the Buoy. Over some time, when marine barnacles are found on the surface and underneath an EVA Mooring Buoy, it (only weighs 1/4 of a Steel Buoy) can be easily flipped over 90 degrees on the surface and cleaned in place without removal and repainting. EVA-Polyurea Mooring Buoys overcame most of the previous problems on the Steel Mooring Buoys and waived the ongoing maintenance costs.
There are many Steel-Fibreglass Through Chain Buoys and HDPE Buoys available nowadays. The cylindrical body of a Steel-Fibreglass or HDPE Mooring Buoy will indeed last better in seawater than a Steel Mooring Buoy; however, its hollow structure or middle shaft made of mild steel may pull apart from the cylindrical body due to rusty and worn out after a couple of years. Eventually, the heavy rust and marine barnacles generated inside the hollow structure will seize the Chain inside the Through Chain Buoy. Besides the middle shaft or hollow structure problems, some HDPE Buoys are too narrow and too high; please note that the higher the Mooring Buoy afloat on the surface, the higher the chance of leaning sideways, causing the growth of marine barnacles on the top half of the Mooring Buoy. That is why we only tailor-made all EVA-Polyurea Mooring Buoys based on the Customer’s Boat and Chain requirements.
EVA Mooring Buoys made by us are available in two versions: Middle Shaft Version consists of a middle shaft with top & bottom mooring rings all-in-one made of stainless steel and fully wrapped around by EVA, then thoroughly sprayed with 5–8 mm thick of Polyurea for watertight, maintenance-free and long-lasting; or the Through Chain Version consists of a stainless steel hollow structure that allows the Chain to go through. The colour choice of Yellow, Green and Red is available upon request.
Mooring Chains, Swivel and Shackles
Concrete Sinkers
Unlike nowadays, most Concrete Sinkers laid before were undersized (did not meet the required weight) due to the lack of prior inspection by the Hong Kong Marine Department. A Concrete Sinker that meets the necessary weight (the cubic volume) for assessment seems a simple matter for most Contractors nowadays. However, the Lifting Eye Ring is always and still undersized!
If the Lifting Eye Ring is too small (Ring diameter and radius), the standard Type-D Anchor Shackle (40 % bigger than a normal Chain-link) can’t go through; thus, a non-standard or undersized Shackle will be used.
Moreover, after these undersized Lifting Eye Ring and Shackle submerge underwater for a couple of years, would they still be able to sustain the Mooring Chain’s pulling forces during a heavy storm? Would they pull apart underwater during the subsequent lift for Chain renewal? If it does happen, the Boat Owner has to pay again for a new Sinker and reinstallation!
Mooring Lines
Finally, no matter how good a Mooring System has been made and installed, improperly secured or misusing an undersized Swivel on the Mooring Lines may cause the Boat to be lost during a heavy storm. About ten Boats were lost after the Super Typhoon [Mangkhut] because of the failure of the stainless steel swivel on the Mooring Lines.
Liability of the Mooring System
Boat Owners or Yacht Clubs are not always aware of all the requirements of a Mooring System. Even some Contractors do not fully understand all the standards and conditions; or choose to ignore them if the fulfilment cost is comparatively higher.
Nevertheless, the Boat Owners are ultimately responsible for the quality and compliance of the entire Mooring System. In case of any failure during a heavy storm, when you proceed with the damage claims (your Boat and the implicated parties) against the Boat Insurance Company, they will then employ an expert to inspect and verify your entire Mooring System for non-compliance. Selecting a Professional and Experienced Contractor for the job in the first place is highly recommended.

EVA-Polyurea Mooring Buoys Vs Traditional Steel Mooring Buoys
Item |
Considerations |
EVA-Polyurea Mooring Buoys |
Traditional Steel Mooring Buoys |
|
1. |
Rusty and Worn Out |
EVA-Polyurea Mooring Buoy will never get rusty and worn out. The top and bottom Mooring Rings and Middle Shaft are all-in-ones made of stainless steel; no painting and maintenance are required. | A Steel Mooring Buoy and its top and bottom Mooring Rings made in mild steel will require continuous maintenance, including removal, repair, anti-fouling painting and replacement almost every two years. |
|
2. |
Pulling Forces |
Sustaining all pulling forces by the Middle Shaft. The Mooring Buoy itself only acts as a floatation unit to support the weight of the Mooring Chain. | Sharing the pulling forces among the cylindrical steel structure of the Mooring Buoy. In case of ageing or lack of maintenance, it may be creaked, holed, sunk or pulled apart during a heavy storm. |
|
3. |
Collision |
The cylindrical body of an EVA-Polyurea Mooring Buoy is a soft, lightweight and highly abrasive material. In a collision, the impact forces will significantly reduce, causing no damage to the Boat and the Buoy. |
Damage to the Steel Mooring Buoy and the Boat even in a minor collision. |
|
4. |
Weight |
An EVA-Polyurea Mooring Buoy of 1.0 meters in diameter only weighs about 120 Kg. The Mooring Buoy’s material (EVA) is lightweight (buoyant), long-lasting and maintenance-free. | A Steel Mooring Buoy of 1.0 meters in diameter weighs about 550 Kg. In case of ageing or damage (cracked and holed), it will sink; unless filled with Styrofoam inside. But it will require additional costs and procedures. |
|
5. |
Buoyancy |
The weight of a Mooring Chain 26 mm x 12 meters in length is about 170 Kg (downward force). In order to maintain 1/3 – 1/2 of the Mooring Buoy stays afloat on the surface as required, an EVA-Polyurea Mooring Buoy of 0.8 meters in diameter only needs 0.8 meters in height to offset the downward forces and maintain about 0.4 meter stays afloat on the surface. | In order to maintain 1/3 – 1/2 of the Mooring Buoy stays afloat on the surface as required, a Steel Mooring Buoy of 1.0 meters in diameter needs about 1.2 meters in height to offset the downward forces and maintain about 0.6 meters to stay afloat on the surface. Higher the Mooring Buoy afloat on the surface, the higher the chance of leaning sideways, which causes the growth of marine barnacles and wearing out on the top half of the Mooring Buoy. |
|

Manufacturing of the Non-metal Mooring Buoys and Marine Solar-lighted Wreck Buoys
All Non-metal Mooring Buoys and Marine Solar-lighted Warning Buoys (Class 1 and Class 2) are tailor-made at our Factories in mainland China (PRC) to the Customer’s Boat and Project requirements. All Products fully meet the needs of the Hong Kong Marine Department.
KKCL also designed and supplied the EVA-Polyurea Wreck Buoys with Solar-lighted Lantern to the Hong Kong Marine Department as requested.
The manufacturing processes of the EVA-Polyurea Middle Shaft Mooring Buoys, Marine Solar-lighted Wreck Buoys and GRP-PU Through Chain Mooring Buoys are as follows:
| 1. | Firstly, assemble the Pre-cast EVA with an all-in-one stainless steel middle shaft; or build up the Fiberglass (GRP) Module with the stainless steel hollow structure to form the size of a required Mooring Buoy. |
| 2. | Secondly, spray the EVA cylindrical body with several coats (5–8 mm thick) of Polyurea mixed with the desired colour by the Computerized Spraying System. Polyurea is a newly developed material that is highly abrasive, heat resistant and never worn out, it will dry immediately upon spraying. For Fiberglass (GRP) Through Chain Buoys, install the Reinforced Rubber Fenders first, then fill up the GRP Module entirely with rigid Polyurethane (PU). For proper chain connection and boat mooring, a separate stainless steel Mooring Ring will be provided with each Through Chain Buoy. |
| 3. | Finally, dress up, mark the Buoy Number assigned, do anti-fouling painting, and pack up for delivery. |

Boat Mooring Requirements in Hong Kong
The size of a Mooring System depends on the Boat’s total length. The Mooring Chain’s size and the Concrete Sinker’s weight required will be specified in the Letter of Permission from the Hong Kong Marine Department. The type and the size of the Mooring Buoy are not listed; however, the Mooring Buoy is required to have sufficient buoyancy to support the weight of the Chain at the fullest stretch and should be 33 – 50 % greater than the combined weight of the suspended components (i.e. 1/3 – 1/2 of the Buoy should stay afloat on the surface after it has been chained up).
Generally, a Boat’s total length between 5 – 8 meters will use a Chain size of 12 – 18 mm, and an EVA Mooring Buoy of 0.6 meters in diameter will be used; a Boat’s total length between 9 – 11 meters will use a Chain size of 25 – 32 mm, and an EVA Buoy of 0.7 – 0.8 meter in diameter will be required. A Boat’s total length between 11 – 26 meters will use a Chain size of 32 – 40 mm, and an EVA Buoy of 1.0 meters in diameter will be required; a Boat’s total length between 24 – 41 meters will use s Chain size of 40 – 45 mm, and an EVA Buoy of 1.1 – 1.2 meters in diameter will be required. A Boat’s total length of 42 – 56 meters will use a Chain size of 50 mm, and an EVA Buoy of 1.3 meters in diameter (dependent upon the water depth and Chain Length) will be required. Please note that the Buoys’ Diameter mentioned above will be much bigger and heavier if Steel Mooring Buoys are used.
EVA Mooring Buoys and Marine Solar-lighted Warning Buoys
Our EVA-Polyurea Mooring Buoy, made with stainless steel Middle Shaft, is very lightweight (buoyant), soft, highly abrasive, and never worn out. It may last for ten years without extensive care.
With our fully equipped Production Lines in mainland China (PRC), the cost of making an EVA-Polyurea Mooring Buoy is very compatible with making a Steel Mooring Buoy with Styrofoam inside and Fiberglass outside, but the durability and maintenance-free are much better.
Kinetic Key Company Limited (KKCL) is more than capable of supplying and installing the full range of Mooring Facilities (Mooring Buoys, Mooring Chains and Concrete Sinkers) and Marine Solar-lighted Warning Buoys (Class 1 or Class 2) for the Yacht Clubs, Private Boat Owners and Marine Construction Companies.
