About This Presentation

Slide 1 - API Recommendation Practice Temporary Crane Installation
Slide 2 - Crane Design Temporary cranes are frequently utilized for construction, maintenance and/or for installing equipment that the platform crane may be incapable of achieving within it’s operating limits. These temporary cranes are transported and installed on marine facilities and placed into service once the rig up and testing are completed. Since they are not the permanent crane, their fitness for purpose are more specifically identified in the tasks they are mobilized to address. Consideration should be given to setting a threshold standard such as API RP 2C 5th edition for example, or other recognized industry standard for cranes that are placed into service. A threshold standard could help in providing both the lease and lessor an objective recognized standard by which to measure a cranes design standard. Critical components shall meet API Spec 2 C Criteria at time of manufacture Other “fit for purpose” standards or specific operating requirements can help assure that an adequate crane is selected for the specific job(s). Provider of the temporary crane should submit, if requested, any documentation or design parameters that the crane was designed and manufactured to. This could be in the form of certification such as a API Spec 2C 5th Edition or other justification by engineering analysis, review and materials of construction. Crane Pedestal, substructure, base beams and all crane tie-down connections should be designed in accordance with API Recommended Practice 2A, latest edition. The load capacity of these components should be included in rating the load limits of the crane. Continued
Slide 3 - Crane Design-Cont. Provider should submit substructure, base beam, substructure-to-base beam connections and base beam tie-down design in writing for the subject crane setup and certify that such design is performed by a qualified person and that such design is specific to the setup of the proposed crane at the proposed platform. The design submittal should include, but not be limited to, the following: A. Drawing or sketch of substructure, base beams, substructure-base beam connection and base beam tie-down detail. B. Specification of materials and/or weld electrodes to be used C. Welding and/or bolt torque procedures D. Maximum pedestal reactions:
Slide 4 - 1) Maximum moment, corresponding thrust, boom length, radius static, rate load, load factor 2) Maximum Thrust, corresponding moment, boom length, radius, static, rate load, load factor 3) Maximum reaction at tie-down points should be provided. E. Weights of the crane components F. Outside-to-Outside Dimensions of the crane components G. Substructure and base beam drawings (plan, elevations, and sections) showing all dimensions, stiffener locations and thicknesses All substructure, base beam, connections, and tie-down details should be reviewed by a qualified person prior to commencement of a job. The qualified engineers review of the substructure, base beam and tie-down details should not limit the contractor’s design and operating liability, nor should such review replace the requirements of any or all of this and other applicable codes and specifications. Stresses and loads transferred to offshore platform by the crane will be analyzed by the customer. Platform modifications, not including tie-down details, necessary to support the transferred stresses and loads will be analyzed by the facility owner. Crane Design (Continued)
Slide 5 - Crane Equipment All Cranes operating on offshore structures should Shall have anti-two-blocks devices on main and auxiliary lines. Crane should shall be equipped with boom high angle limiting devices if required Crane should shall have a load indicator. Temporary Crane Provider should shall supply emergency lowering equipment if requested when handling personnel Temporary Crane Provider should supply certification for boom hoist, main hoist, auxiliary hoist cable, and pendent lines in accordance with 6.1.6 Temporary Crane Provider should furnish slings which are certified in accordance with 6.2.2.1. for temporary crane component pre rigging components Crane should be equipped with emergency slew and swing procedure. Access should be provided to the boom for inspections on boom tip and two-block system.
Slide 6 - Load Testing Requirements Temporary Crane Provider should shall perform load tests of the temporary cranes in accordance with Annex C of this standard. Temporary cranes will be subject to the appropriate inspections and load testing after each rig-up or relocation of cranes as per Annex C. If performing a dynamometer load test, Temporary Crane Provider should furnish a properly calibrated dynamometer with appropriate dial range for the specific load testing requirements. In addition, it is suggested that the Temporary Crane Provider submit a calibration certificate furnished by a third party for the subject dynamometer prior to beginning offshore work. Function Test of Temporary Crane Minimum should include rated load to water level and back up, boom up and down through radius, slew/swing with rated load in the quadrants of the lift to be performed as determined by crane customer.
Slide 7 - Preventive Maintenance Temporary Crane Provider should Shall inspect, maintain, repair and document work on crane in accordance with the following guidelines: API RP 2D Section 5.1.1.4 – Annex D and relevant manufacturer recommendations. Temporary Crane Provider’s preventative maintenance and repair program should Shall be performed by qualified personnel in accordance with API RP 2D Section 5.3.1. While the temporary crane is in use on the customers property, the temporary crane provider is responsible for all pre use, monthly, quarterly and annual inspections of the crane. Upon installation of crane on offshore structure, contractor should Shall perform and document an annual crane inspection in accordance with Section 5.3.1. An annual inspection form should be submitted verifying that the inspection was completed. Quarterly crane inspections should Shall be performed and documented by a qualified crane inspector designated by the temporary crane provider. Pre use and monthly crane inspections should Shall be performed and documented by a qualified crane operator designated by the temporary crane provider. Documentation of all inspections should be submitted to the customer representative in accordance with 5.1.2.6.3 - 5.1.2.6.4, unless waived by the customer. Temporary Crane documentation should Shall be kept for a period of four (4) years, and accessible upon request. Temporary Crane documentation can May be copies of originals. Temporary Crane bare rental customers are responsible for pre use inspections, monthly inspections, quarterly inspections, annual inspections, maintenance, operations and documentation of work of temporary crane.
Slide 8 - Work History Temporary Crane Provider should be prepared to submit a work history report of the proposed crane for the last ten (10) jobs or for all jobs in the last twelve (12) months (whichever is shorter). The subject report should include, but not be limited to, the following minimum job specific information: Company, contact name and phone number of reference Location and duration of job Crane Configuration, including boom length, sub-base and/or base beam arrangements, etc. Report of any crane modifications, repairs and/or maintenance performed (i.e., pendant lines) If applicable, number of times that crane bolts have been torqued Bare Rentals of Temporary Crane records as provided by users
Slide 9 - Checklist of Information to submit upon Award Temporary Crane Provider should submit the following information to the customer. Layout of Crane on Platform Drawings Crane Sub-base Beam Drawings Crane Base Beam Drawings Sub-base to Base Beam Connections Base Beam to Platform Tie-Down Design These drawings should be reviewed by a qualified person Tie-Down Weld Design The weld design may be indicated on the tie-down drawings. Weld type, size and location should be indicated. These drawings are recommended to be reviewed by a qualified person. Torque Procedure If the crane pedestal is attached to the structure via bolts, then a recommended torque procedure should be submitted. Bolt size, nut size, torque sequence and torque should be indicated Weld Procedure If the crane pedestal is attached to the structure via welding, then a weld procedure should be submitted. A typical AWS format is sufficient.
Slide 10 - Load Testing Procedure Whenever a Temporary Crane is Installed, Annex C requires that a load test be performed in accordance with the following table The API 2D Load Test do not require that the load be swung Continued
Slide 11 - Load Testing Procedure (Continued) Pre-Load test Inspection is done performed by a qualified inspector on temporary crane Perform Recommended Inspection Perform post Pre NDE on temporary crane tie town welds Load test performed on temporary crane The Test Load should be applied by one of the following methods: Suspended Weight Method – Select a suitable test load (per load testing table.) Assemble the load, lift load and boom out to the desired radius. With the load suspended set the load hoist and boom hoist brakes and check for drum rotation (the load test does not require that the test load be boomed or swung). Dynamometer Method – Determine the available dynamometer tie-down locations. Measure and record the radius value. Align the boom point with the tie-down and attach the dynamometer. Verify that the load hoist line is vertical, pull with the load hoist until the desired test load is indicated on the dynamometer. Set the load hoist brake and check for drum rotation. Tie down points must be in all the working quadrants of the lifts Initial rig up the suspended method is recommended. Dynamometer method can be utilized for a pull test. The load test report should include, but not be limited to, the following information. Auxiliary Line, select appropriate load for components being tested. Actual Test Load Actual Test Radius Indicated Load Hydraulic Hoist Pressure Main Hoist Line, Select appropriate load for components being tested. Actual Test Load Actual Test Radius Indicated Load Hydraulic Hoist Pressure Check Radius or Boom Angle Indicator at four (4) values including maximum and minimum. After Load Testing is completed re-inspect the crane (Annual Inspection) and all NDE Tie Down welds. If everything passes inspections temporary crane can be put in service upon completing NDT.
