Large Ocean Buoys

In practical applications, large ocean buoys are either used individually as "offshore markers", such as delineating oil field operation areas and marking prohibited navigation zones; Either multiple devices are strung together to form a "floating array", supporting deep-sea aquaculture cages or auxiliary equipment for offshore wind power. Due to its large size and strong buoyancy, even equipment weighing several tons can float steadily on the sea surface and sway slightly with the waves, avoiding being overturned by strong winds and waves. It is a "key buoyancy role" in offshore aquaculture, marine exploration, and maritime rescue.

Product advantages

1. Strong and stable buoyancy, reliable load-bearing capacity: Large ocean buoys utilize a closed cavity structure and a large volume design, resulting in exceptional buoyancy. Even when supporting aquaculture cages and monitoring equipment weighing several tons, they remain stable and stable on the sea surface. The even distribution of force prevents tilting or capsizing due to excessive weight. They can easily support entire fish cages during offshore aquaculture operations.

2. The fiberglass material is UV resistant and does not age even after prolonged exposure to sunlight, eliminating the need for frequent replacement and saving a lot of trouble.

3. Flexible in function and adaptable to various scenarios: signal lights can be installed on the top GPS， Easy to locate and identify;

4. The bottom can be connected to breeding cages, monitoring equipment, and can also be used to tie small boats. Whether it is a "buoyancy base" for offshore aquaculture, a "no navigation mark" for oilfield operation areas, or a "temporary floating platform" for maritime rescue, it can be used with slight adjustments and has strong versatility.

5. Good durability and low long-term cost: Although it may not be cheap at the beginning of purchase, it is resistant to manufacturing and not easy to break, so there is no need for frequent maintenance or replacement in the future. For example, a floating float with a steel frame and anti-corrosion coating can last for more than ten years; Even HDPE can be used for more than five to six years, and the annual cost is actually more cost-effective than a small float.

6. Convenient management, no need to spend too much effort: Large ocean buoys are large and easy to locate, making them less likely to be lost at sea. GPS can be used to accurately locate them. Daily inspections are also very convenient. Simply inspect the buoy from a distance for damage and use equipment to verify proper positioning. This eliminates the need for frequent close-up inspections by a vessel, saving manpower and resources.

FAQ

Q: How long can a large ocean float last? Will it break down quickly?

A: Normally, the energy pipe can be used for 5-15 years, depending on the material - HDPE material has good corrosion resistance and can last for 8-10 years without serious collisions; Fiberglass reinforced plastic (FRP) is more durable and can last for 10-15 years; As long as the coating of the steel frame is not damaged, it can still be used for more than 10 years. As long as you avoid the impact of rocks and repair small cracks in a timely manner, it is not easy to break.

Q: Will the float be knocked over by waves on the sea? Or washed away by ocean currents?

A: It generally does not flip over. It is designed to be stable, with a large enclosed cavity and a low center of gravity. Even when encountering waves of 3-4 meters, it will only sway slightly; As for being washed away, most floats will be fixed to the seabed with anchor chains or sandbags. As long as the anchor chains are thick enough and firmly fixed, ordinary ocean currents cannot pull them, and only extreme typhoon days may require early reinforcement.

Q: How should we maintain it on a daily basis? Do we need to send ships to inspect regularly?

A: There is no need to run frequently, mainly do three things: first, check the location through GPS every month to confirm that there is no drift; Secondly, every three months, send a ship to take a close look and inspect the surface for cracks, paint peeling, and loose straps or connectors; The third is to promptly repair minor damages - for example, if HDPE floats and cracks, use special glue to stick them together, or use fiberglass repair resin for easy maintenance.

Q: How much weight can the float bear? Can heavy equipment be mounted?

A: The load-bearing capacity depends on the size and material. Small ones (with a diameter of 1-2 meters) can hold 1-2 tons, such as small monitoring instruments; Large HDPE floats (with a diameter of 3-5 meters) can bear 3-5 tons, while those with steel frames can reach 8-10 tons. They are suitable for hanging deep-sea aquaculture cages and large-scale exploration equipment. When making a purchase, inform the manufacturer of the load-bearing requirements and they will customize the appropriate specifications.

Q: Will shellfish and algae in seawater attached to floats affect their use?

A: It may have some impact. If attached too much, it will increase weight and slow down the flexibility of the float. Therefore, an anti adhesion coating is usually applied to the surface of the float, which can reduce adhesion by about 80%; If it's already grown, just rinse it off with a high-pressure water gun during maintenance every year. There's no need to clean it thoroughly, and a small amount of adhesion won't affect buoyancy.

Q: How to repair a damaged float? For example, what if there is a hole or an air leak (inflatable)?

A: Repair according to the situation - if there is a hole in the HDPE or fiberglass float, first wipe the area around the hole clean, apply a patch of the same material and special adhesive, and let it dry for 24 hours before use; Inflatable float leaks, first find the leak point (you can apply soapy water to the surface, the area where bubbles appear), then use a leak patch to fix it. After filling, let it sit for a day. If there is no leak, it can be used normally.

Q: Will the float freeze and crack when used in cold sea areas?

A:As long as the right material is selected, the manufacturer will make adjustments for low-temperature environments, such as adding antifreeze to HDPE floats to prevent them from becoming brittle even at -20 ℃; Fiberglass floats will thicken the surface layer to prevent cracking caused by freeze-thaw cycles (daytime thawing and nighttime freezing). When purchasing in northern sea areas or high latitude regions, mention "low temperature resistance" and the manufacturer will provide a suitable model.
