The APC is a hydraulically activated coring tool that is designed to recover undisturbed core samples from soft ooze and sediments up to 250 meters beneath the seafloor. References the recovered cores to magnetic north. Add or remove set screws to control scoping velocity. Prevents rotation of the corer relative to the piston rod. Full BHA compatability with XCB tool.
All components require care in handling beyond the normal for drill collars.
