发明名称 IMPACT ABSORBING ACCESS PLATFORM FOR DRILLING STRUCTURES
摘要 Generally, the subject matter disclosed herein relates to an impact absorbing "diving board," or access platform, of a drilling rig "fingerboard," or pipe racking assembly. One illustrative diving board assembly of a drilling rig fingerboard assembly disclosed herein includes a first end proximate the drilling rig and a second end positioned remote from the first end, where the first end is more proximal to the drilling rig than the second end. The illustrative diving board assembly further includes a clamping assembly operatively coupled to the first end and to the second end, where the clamping assembly is positioned between the first and second ends and defines a pinned connection adapted to permit a rotation of the first and second ends relative to a plane defined by the fingerboard assembly.
