Land based dynamic sea motion simulating test drilling rig and method.

摘要

A land based dynamic sea motion simulating test drilling rig comprising: - a soil bound foundation, - a pivot structure secured to said foundation and providing at least one horizontal pivot axis, - a motion base mounted on said pivot structure and pivotable about said at least one horizontal pivot axis relative to the foundation, - a drilling tower erected on said motion base and having a foot that is secured to said motion base, the drilling tower being provided with a hoisting device adapted to manipulate a drill string section in a vertical firing line, - a drilling tubulars storage adapted for vertical storage of drilling tubulars, said tubulars storage secured to said motion base, - a tubulars racker device arranged and configured to move drilling tubulars between the drilling tubulars storage device and the firing line allowing for assembly and disassembly of a drill string section in the firing line, - a motion drive adapted to impart cyclic pivoting motion about said at least one horizontal pivot axis to the assembly of the drilling tower, drilling tubulars storage, and tubulars racker device in order to simulate said assembly being subjected to sea state induced motion.
