Overview

The SmartRacker vertical pipe-handling system triple and quad column rackers are advanced pipe handling systems for jackup rigs, semisubmersible rigs, and drillships. They perform all vertical pipe-handling operations on the drill floor, including racking stands, building stands in the mousehole, picking up singles from the catwalk, laying out singles to the catwalk, and tripping in and out of the fingerboard.

These systems are fully-automated with a robotic control system that controls and monitors all operations and protects the machine and rig from operator failure. The machine can be operated in auto mode, semiautomatic mode, manual mode, override mode, and emergency mode. With its unique gripper head design, the SmartRacker system can handle all types of pipe, including production tubing, drillpipe, casing, and spiral drill collar.

Using AC or hydraulic technology for all main functions, the SmartRacker system is very accurate and reliable as well as easy and quick to operate. This efficient handling system is designed for the most demanding applications in an offshore environment. It is designed according to DNV and NORSOK regulations and is CE marked.
