The crane is designed for the life, duty and service conditions as stated in the technical data and in the Shipyard’s Technical Specification. The electro-hydraulic pedestal crane is Type A as shown in figure 1 crane assembly of API Spec. 2C 6th Edition, September 2004. The crane is capable of lifting, swinging, luffing and lowering loads at capacities, radii and speeds in conditions as specified in the technical data, specifications and drawings. Safe Working Load (SWL) is the actual loads that can be lifted and are not include the hook, block and hoist rope weights. The crane is self-contained, electro-hydraulic driven, hydraulically operated, ram luffing, stiff boom box type, pedestal mounted and fully revolving; furnished with a pedestal adaptor, an enclosed cabin and all auxiliary equipment suitable for duties associated with an offshore vessel. The function of the crane includes but not necessarily be limited to the following: A) Offloading item such as wire line equipment and coil tubing package, the heaviest maintenance item materials (drilling tubular goods) from supply boat. B) Transportation of personnel to/ from a supply boat. C) Handling materials on platform deck. D) Removing heavy components with various characteristics for their installation on the deck at permanent locations (lay down areas). The crane is provided with lifting lugs on all major assemblies to facilitate erection or disassembly of the complete crane package. The crane is equipped with a main hoist and auxiliary hoist. The main hoist is capable of reeving various multi-falls of rope to achieve a range of lifts for heavy loads. The auxiliary hoist is of single fall, used for lifting light loads. The crane’s flood-lights and electric equipment installed on the boom are certified for safe area (unless otherwise specified). The crane is continuous rotary type, rotating in both direction through 400° limited. The cranes power is sufficient to ensure that the one movement under full load, full speed and under worst conditions. Simultaneous operation is possible at reduced speed. All areas of the crane are accessible for inspection, maintenance and repairs. No feature on the crane presents or creates a safety hazard to personnel.84
  • 85. Nunce Deck operating manual Deck cargo crane DESIGN The crane is designed and constructed in accordance with API SPEC 2C, Specification for Offshore Cranes, 6th edition, September 2004. The crane is designed to provide the SWL capacities at the required load, radii and speeds. These SWL capacities are used to determine the Category 1 (static) and Category 2 (dynamic) design loads as defined in API SPEC 2C. For the purpose of evaluating the dynamic ratings for lifts from boats, off-lead and side-lead angles are used as stated in the technical data for the sea states indicated. Also the maximum operating wind speed is included in the evaluation of side forces. The out-of-service wind speed is considered with the boom in the horizontal position restrained in a rest. Detailed calculations are prepared for all primary loaded members of the crane, such as: • Pedestal adaptor. • Swing Circle bearing. • Revolving Base structure. • Frame. • Boom. • Running ropes. • Boom foot pins and sheave pins, etc. • Hoist winches drums and shafts.85
