More than storage reelers, Logan’s CT reelers are CT winches, where the reelers provide full torque control for the tubing without the need for a standard injector head. This reduces space required compared to standard tubing reeler/injection head combination, and it allows for a larger fluid storage footprint on deck. When the equipment required to handle CT has a small footprint, more deck space can be dedicated to hauling fluid, which increases profitability for the operator, Logan said.
Whereas Logan has built several sets of these machines in the past with fixed drums, this is the first unit Logan has delivered with a removable drum, which means the unit footprint can remain static on the vessel while the drums can be taken to a shore base for unspooling and respooling. They are transported in a purpose-built DNV lift rated drum basket, fully secured and protected. The swap out drum also makes the machine faster to build, reducing typical assembly time for the drum and drive train from two weeks to two days. Coiled Tubing Directional Drilling
At 15,000-psi working pressure, 10,000 ft of 2-inch CT was provided on the drum, with live swivel and isolation valves on the unit. The suite of equipment provided for this work includes a spare drum, adapter to allow it to fit into most tubing service spoolers at the tubing manufacturer’s facilities, transport basket and lifting set along with the reeler, HPU, control stand and interconnect lines. Logan also provided a purpose-built overboarding platform with a translating/clamshell to accommodate OneSubsea’s end connection philosophy.
Coiled Tubing Dean Carey, Logan's technical director, said, “We placed a work deck, dimple connector, test tool, controls and safeguards on this overboarding platform to give the crew plenty of access to the volume of space under the overboarding point. The overboarding platform also provided a reeler deck loading spreader effect on the vessel’s deck. We believe this is truly the next evolution in coiled tubing deployment offshore and provides significantly more convenience for our customers."
