Osaka’s soft
skin chain through buoys have an empty steel pipe core, where either a chain is
already attached and has two shackle ends to be connected to the main chain
line, or can be left empty so it can go through inside a chain or a cable,
which can be used for different applications, such as support.
Their
resilient soft skin exterior provides strong resistance to impact and harmful
environments, reducing maintenance needs and ensuring long-lasting performance
in offshore applications.
NOTE: Weight in kg. Measurements in mm.
These are our standard dimensions, after product customization deviation margins might apply.
Our smallest sizes of Chain Through Buoys are typically between 1 Ton and 2,2 Tons net buoyancy, which can be achieved with buoys as small as 1 and 1,5 m in diameter. These are typically used on smaller mooring lines, as a support component of fish farms in the aquaculture industry. They distribute the load equally or as desired across the chains connecting longer rows of fish farm cages, and thanks to their superior design and durability from Osaka, they are ideal for farms exposed to all sorts of weather conditions, including the harsher weathers. They are also commonly used for floating marine barriers or floating booms. Smaller sizes are also available at Osaka Industry, as they are very useful in other industrial applications and for fishing boats and in private markets, although we would usually recommend our other product, our spherical buoys, which are able to achieve even lower ranges of buoyancy, are easier to transport and install, and are a product that we work with just as much as this.

These sizes are our most commonly requested models from this serie of buoys, starting at 2,7 T and up to 4,5 T, and they are used for most standard applications in the offshore and Oil & Gas industry. These sizes can be reliably used on general mooring chain support in the Offshore, such as for oil rigs or tanker ships, even for SPM (Single Point Mooring) anchoring or in ancilliary larger systems, or in any application where a class certified offshore chain of grade R4, R4, or the needed grade, has to pass directly through the buoy, and this one needs to be able to move free in the event of a drastic chain movement or other scenarios.

The 5.5 T buoy is the largest standard size of this type of chain-through buoy, and is typically employed in the larger offshore applications. For even larger sizes, we would recommend other types of support buoys that we have available on our website, or to directly contact our team who will present you a tailored commercial and technical proposal, completely adapted to your project requirements. These even larger options can achieve a range between 10 tons to even 50 tons of net buoyancy. For special offshore projects where 100 Tons or more is necessary, our modular chain through support buoys, our finest piece of technology in the field of Offshore Buoyancy, simply send an email to osaka@osakaindustry.com and let us do the rest.
