Korean Offshore Operator Deploys OUCO 3T Knuckle Boom Crane for Dredging and OSV Marine Operations

OUCO INDUSTRY successfully delivered a 3T Offshore Knuckle Boom Crane to a Korean marine operator for deployment on crane barges, dredging boats, and OSV platforms. This project highlights OUCO's ability to deliver compact, high-flexibility lifting solutions engineered for Sea Condition Grade 4 environments, where reliability and precision are non-negotiable.

The client, a prominent Korean maritime operator, required a versatile knuckle boom crane for diverse tasks across multiple vessel types — from load transfers and supply handling on floating platforms to subsea equipment deployment. Operating in dynamic sea conditions with wave heights up to approximately 2 meters, the client prioritized maximum lifting performance with minimal deck footprint and maintenance overhead.

The articulated knuckle boom folds inward, reducing the crane's footprint and enabling operations in tight deck zones. This design minimizes pendulum motion during load engagement, enhancing safety and precision near vessel structures. 360° continuous slewing and hoisting speeds of 18–20 m/min ensure rapid cargo transfers and pinpoint positioning for time-sensitive offshore tasks.

Sealed hydraulic circuits and corrosion-resistant coatings minimize maintenance requirements. The energy-efficient hydraulic system reduces power consumption by up to 30% compared to conventional models. The compact design eliminates extensive deck modifications, saving installation costs and maximizing space utilization.

Oil-filled cylinders, marine-grade coatings, and sealed hydraulic systems protect against harsh saline environments and dynamic sea motions. The crane maintains stable performance from -10°C to +50°C, with an optional polar-grade package extending capability down to -40°C. Fail-safe brakes, overload protection, and emergency-stop functionality ensure operational safety aligned with ISO maritime standards.

Dual control modes — radio remote control and onboard console stations — provide operational flexibility. Real-time monitoring displays load weight, boom angle, and environmental conditions, reducing human error and enhancing efficiency.

OUCO INDUSTRY, founded in 1984, operates a 48,000-square-meter manufacturing facility in Jiangsu Province, China, with over 150 skilled professionals. Every knuckle boom crane undergoes a rigorous quality protocol:

1. Classification Society Material Certification: All structural steel is fully traceable and certified to ABS, CCS, and RMRS standards.
2. Hydraulic System Integrity Testing: Pressure testing, leak detection, and functional cycle validation of all sealed circuits.
3. Full-Load Operational Trials: Simulated working conditions including slewing, luffing, hoisting, and load verification.
4. Pre-Shipment Inspection: Final dimensional verification, coating inspection, and complete documentation review prior to containerized shipping.

Founded in 1984, OUCO INDUSTRY is a globally recognized manufacturer of high-quality marine cranes, lifting systems, and material handling solutions. With over 40 years of experience and a 48,000-square-meter facility staffed by 150+ skilled professionals, the company serves clients worldwide across luxury yacht, offshore, port, and industrial sectors. OUCO's commitment to innovation and reliability has made it the preferred partner for maritime operators seeking lifting solutions that deliver consistent performance in the most unforgiving marine environments.

The Korean marine operator received a fully certified, factory-tested 3T Offshore Knuckle Boom Crane delivered within the 30-day timeline. The crane has been commissioned across multiple vessel types — including crane barges, dredging boats, and offshore support vessels — delivering the flexibility, precision, and cost-efficient performance essential for complex multi-role maritime operations.
