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)
