A commissioning survey would usually include and IDT or IAT commonly known in the industry.
As part of the unit acceptance testing, an operating and load test would be carried out to fully test all equipment and systems operating at as close to full capacity as practicable and also to place the engines and generators under as much load as possible in the rig-up environment.
One of the primary objectives of completing this test is to ensure that ALL systems of the drilling rig, once built will work in harmony with each other in simultaneous operations similar to those that will be experienced in an operating environment as opposed to the singular tests of individual component testing in a construction and rig-up atmosphere.
