The Knuckle Boom Marine Crane, also known as an articulated or folding boom crane, is a specialized lifting solution designed for offshore and marine environments. Unlike conventional straight‑boom cranes, its hinged boom structure provides exceptional flexibility, allowing the crane to fold into a compact footprint when not in use while delivering superior reach and maneuverability in confined spaces.

1. Offshore Platform Supply & Logistics Cargo Transfer: Lifting pipes, drilling equipment, containers, and consumables from supply vessels to fixed platforms or floating installations with precise load control. Deck Handling: Moving heavy equipment across the platform deck, utilizing the knuckle boom’s ability to reach around obstacles and into tight corners. Personnel Basket Transfer: Safely transporting personnel via specialized baskets between vessels and platforms, with smooth hydraulic controls to minimize swinging.

2. Floating Production Storage & Offloading (FPSO) Operations Equipment Maintenance: Lifting pumps, valves, and subsea components from the FPSO deck to workboats or directly to the waterline for servicing. Mooring Operations: Assisting in the deployment and retrieval of mooring lines, chains, and anchors with the crane’s compact stowage and high‑precision control. Subsea Intervention: Supporting remotely operated vehicle (ROV) launches and recovery, as well as handling of subsea modules and umbilical lines.

3. Drilling Rigs & Drill Ships Riser & BOP Handling: Lifting blowout preventers (BOPs), riser joints, and wellhead equipment during drilling operations, utilizing the crane’s capacity and reach. Deck Load Management: Organizing tubular goods, drill collars, and casing stocks across the rig’s pipe deck with minimal obstruction. Crane‑to‑Crane Transfer: Coordinating lifts between multiple knuckle boom cranes for complex installations where precise positioning is required.

4. Subsea Construction & Intervention Subsea Module Deployment: Lowering heavy subsea structures (manifolds, templates, jumpers) to the seabed with active heave compensation to maintain stable loads in wave‑induced vessel motion. ROV & Tool Handling: Launching and retrieving ROVs and specialized intervention tools, with the knuckle boom’s ability to place equipment precisely over moonpools or side‑deployment areas. Cable & Umbilical Lay: Tensioning and guiding flexible pipes, power cables, and control umbilicals during installation or repair campaigns.

5. Offshore Wind Farm Support Turbine Component Handling: Lifting and positioning blades, nacelles, and tower sections during installation, using the crane’s maneuverability to align components in dynamic sea conditions. Crew Transfer Vessel (CTV) Operations: Loading and unloading spare parts, tools, and containers from CTVs to fixed foundations or turbine transition pieces. Foundation Maintenance: Handling corrosion protection equipment, access platforms, and monitoring instruments on monopiles and jacket foundations.

6. Dredging & Marine Construction Pipeline Installation: Placing and aligning dredge pipes, HDPE lines, or steel pipelines from floating barges using the crane’s ability to operate at extended radii. Rock Dumping: Positioning rock grabs or fall pipes for seabed leveling and scour protection around subsea structures. Temporary Works: Lifting cofferdams, sheet piles, and modular construction units in nearshore and offshore construction projects.
