Logan Industries International Corporation, a world-class machine designer, manufacturer, field service and repair company, has successfully delivered a unique, space saving coiled tubing (CT) reeler suite for OneSubsea, designed to maximise profitability.
More than simply storage reelers, Logan’s CT reelers are coiled tubing 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 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.
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 2 weeks to 2 days.
At 15,000 psi working pressure, 10,000 feet 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 unique end connection philosophy.
Dean Carey, technical director, Logan, says, “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. This is one of the most comprehensive reeler equipment suites Logan has had the pleasure to provide, and we expect it to remain in service for quite some time.”
