DESIGN, SUPPLY AND INSTALLATION OF BOAT MOORING SYSTEMS
The weaknesses of the traditional Steel Mooring Buoys are rusty, worn out and bearing of all pulling forces among the cylindrical structure of the Mooring Buoy. In case of aging and/or collision, the Steel Mooring Buoys will be creaked, holed, sunk or even pulled apart during a heavy storm.
Non-metal Mooring Buoys are available in two versions: Middle Shaft Version (Stainless Steel Middle Shaft with top and bottom Mooring Rings) and Through Chain Version (The Mooring Buoy with Stainless Steel Hollow Structure that allow the Chain to go through). The idea of the Non-metal Mooring Buoys is to remove the stress (pulling forces) from the cylindrical structure of the Mooring Buoy, thus, all the pulling forces will be directly taken over by the middle shaft or mooring chain and the mooring lines to the Boat, the Mooring Buoy itself only acts as a floatation unit to support the weight of the mooring chain and maintain 50 % of its height stays afloat on the surface as required.
high technology support and availability of new material nowadays,
the new designed Non-metal Mooring Buoys are either made with high density
Ethylene-co-Vinyl Acetate (EVA) inside and sprayed with several coats of
Polyurea outside, or Fiberglass Module filled with
hard Polyurethane Foam inside.
Despite the weight and size of a Non-metal Mooring Buoy is much
less than a Steel Mooring Buoy under
the same requirement, a Non-metal
Mooring Buoy is more long lasting
(10 years under normal usage)
and maintenance free for long term operation. It really overcome most of the previous
problems on the Steel Mooring Buoys
and significantly reduce the on-going maintenance costs. Colour Choice in Yellow / Green / Red is also available upon request.
KKCL is a Supplier for Mooring Components, such as Mooring Buoys, Mooring Chains, Swivels, Shackles and Concrete Sinkers etc. and is more than capable to design, supply and install the full set of Mooring System to meet your Boat requirement. Sample of the Non-metal Mooring Buoy is available at our Warehouse at Aberdeen, HK for your inspection and hand-on experience upon request.
Manufacturing of the Non-metal Mooring / Navigation Buoys
All Non-metal Mooring Buoys and Navigation Buoys are tailor-made at our Factory in mainland China (PRC) based on individual requirement and are approved by Hong Kong Marine Department. The manufacturing processes of the EVA / Polyurea Mooring / Navigation Buoys are:
The size of a Mooring System is dependent upon the total length of the Boat, the sizes of the Mooring Chains and Concrete Sinkers used will be specified in the Letter from the HK Marine Department. The size of the Mooring Buoy used will not be listed, however, the requirement is the Mooring Buoy (Buoyancy) should be 50 % stayed afloat on the surface after Chain installation.Higher the Mooring Buoy afloat on the surface, higher the chance of titling sideway that cause the growth of marine barnacles on the top half of the Mooring Buoy. Generally, a Boat of total length less than 9 meters will use Chain size 12 - 26 mm, a Mooring Buoy of 0.8 meter in Diameter will be required. A Boat of total length between 10 - 15 meters will use Chain size 28 - 36 mm, a Mooring Buoy of 1.0 meter in Diameter will be required. A Boat of total length between 17 - 26 meters will use Chain size 37 - 40 mm, a Mooring Buoy of 1.2 - 1.3 meter in Diameter will be required. The entire cylindrical body of the Non-metal Mooring Buoy is very light-weight (buoyant), never get rusty and worn out, no painting is required, it may last for 10 years or more under normal usage without extensive care.
The cost of making a Non-metal Mooring Buoy is very compatible to those Steel Mooring Buoys that are required to fill with Styrofoam inside and fully covered with Fiberglass outside, but the durability and maintenance free is much better. KKCL may design, tailor-made and install the full set of Mooring System to suit your Boat requirement, including Mooring Buoys, Mooring Chains with Swivels, Shackles and Concrete Sinkers etc. upon request.
