Chain Through Buoys

Engineered for the most demanding offshore environments, Hongruntong Marine's Chain Through Buoy delivers critical catenary support and chain protection in SPM systems. Featuring a robust center through-hole design and advanced polyurethane-foam composite construction, this buoy withstands dynamic ocean loads, extreme depths, and corrosive elements – ensuring operational continuity for FPSOs, CALM buoys, and offshore oil & gas installations.

Key Features & Technical Advantages

• OCIMF 2000 Compliant Design – Manufactured in accordance with the OCIMF 2000 guidelines, ensuring safe and reliable performance in offshore mooring and SPM applications.

• Durable Polyurethane Outer Skin – The heavy-duty PU elastomer shell provides superior resistance to abrasion, impact, and harsh marine conditions.

• Resilient Foam Core – Filled with high-energy absorbing EVA/PE closed-cell foam, offering unsinkable buoyancy and excellent recovery performance even after puncture or surface damage.

• Chain-Through Configuration – The integrated chain-through design enhances load distribution, minimizes stress concentration, and extends service life in demanding mooring operations.

• Corrosion & UV Resistance – Engineered to withstand seawater, chemicals, and ultraviolet exposure, reducing long-term maintenance costs.

• Operational Safety & Reliability – High energy absorption with low reaction force provides effective protection for vessels, mooring lines, and offshore structures.

• Customizable Options – Available in various sizes, chain diameters, and buoyancy capacities to meet specific project requirements.

Applications
