Modular workover rig designed for quick moves between platforms
A new workover rig has a modular design for quick rig up and rig down and easy transport between offshore platforms using field supply boats and platform cranes. Pool Energy Services Co.`s new electric-powered platform workover rig recently left Houston bound for Australia`s Bass Strait, where it began offshore operations for Esso Australia Ltd. in July. This SCR (silicon controlled rectifier) rig is rated at 1,000 hp. A sister rig began operations offshore Malaysia for Esso Production Malaysia Inc. in late 1994. The offshore platforms in Bass Strait are within close proximity of each other. The rig must be able to make quick moves from one location to another. The 427-ton rig has a modular configuration, allowing it to be rigged down, transported, and reassembled in this field in about 5--7 days, depending on the weather and supply boat schedule. The paper describes the design and operation of the workover rig.
