Full Revolving Floating Crane Product Introduction
(1) Specifications and Product Parameters
The Full Revolving Floating Crane is a heavy-lift offshore vessel designed for 360-degree rotational operations in marine environments. Key specifications: overall length (LOA) 80-120 m; beam 30-50 m; moulded draft 5-8 m. Lifting capacity ranges from 1,000 to 5,000 tonnes at a radius of 20-50 m, with a maximum outreach of 60-100 m. Revolving speed 0.5-1.0 rpm; powered by dual main engines totalling 5,000-10,000 kW, supported by dynamic positioning (DP2) systems. Ballast capacity 10,000-20,000 tonnes for stability; hook height up to 80 m above waterline.
(2) Product Features, Performance, and Materials
Equipped with an entirely revolving superstructure on a slewing ring bearing for unrestricted 360-degree operation, enabling precise load positioning without vessel repositioning. Performance includes tandem lifting modes for up to 10,000 tonnes combined capacity, with active heave compensation (AHC) systems maintaining ±0.5 m accuracy in wave heights up to 3 m; anti-pendulation controls reduce sway by 70%. Low-emission selective catalytic reduction (SCR) exhaust systems meet IMO Tier III standards; hybrid power options integrate battery storage for 20-30% fuel efficiency in idle modes. Hull and boom fabricated from EH36/FH40 high-tensile steel with yield strength >355 MPa, featuring epoxy-based anti-corrosive coatings and duplex stainless steel for critical components like sheaves and wire ropes. Integrated PLC automation with load moment indicators (LMI), wireless remote controls, and real-time structural health monitoring (SHM) sensors ensures operational reliability and fatigue mitigation.
(3) Product Actual Application Ranges/Scenarios
Primarily deployed in offshore construction for heavy module installation on oil/gas platforms, FPSOs, and wind turbine foundations under IMCA guidelines, handling loads in water depths up to 1,000 m. Supports port infrastructure projects, such as bridge span erection and caisson placement, in coastal zones with Beaufort Scale 6 conditions. Versatile for salvage operations, including sunken vessel recovery per IMO conventions, and decommissioning of subsea structures. Ideal for renewable energy sectors like offshore wind farms for monopile driving and nacelle lifting, as well as shipyard heavy-lift tasks in sheltered harbours, ensuring compliance with ISM Code and flag state regulations across global maritime domains.
