Logan Industries Delivers Second Set of Innovative Coiled Tubing Reelers for Open
Water Well Interventions Logan Industries (Logan), a hydraulic repair, manufacturing and rental company, has manufactured and delivered the second set of a new and innovative design of small- footprint coiled tubing (CT) reelers.
Logan’s new CT reelers are suitable for storing and deploying 10,000 ft of 2 3/8 in. tubing. The CT reelers enable operators to perform open water well interventions without bringing in a full drilling rig; boosting efficiency and reducing costs.
This is the largest reeler Logan has manufactured of this type and
features the smallest footprint in the industry. Logan pioneered new ways of assembling drive systems on large drums, and new methods of ensuring the CT lays and stays on the drum and wraps. Prior to Logan’s development of this solution, no fatigue models existed for CT performance. Since Logan’s development of these types of reelers, distinguished professors have investigated new methods of evaluating CT and have published their findings. Now, Logan’s CT reelers are specified in several of these papers and Logan has helped introduce a new requirement for CT fatigue evaluation.
Dean Carey, Technical Director, Logan Industries, said, “One of our most valued customers trusted our expertise
to deliver them with a unique solution when nothing on the market met their needs. Our new CT reelers are truly innovative designs and game changers for the offshore intervention market because they feature such a small footprint. This enables customers to take on more well stimulant fluid load, meaning they can perform a bigger job for longer. Logan has become the industry leader and the preferred option in CT deployment for open water intervention service providers.”
The first full set of these larger CT reelers was delivered in September 2020.
Why Rely on a Flanged Connection?
The upstream industry is no stranger to barren times of investment but in 2020 this was coupled in the face of a global pandemic where the pinch and uncertainty was seen Worldwide and industry wide. This considered, there has been a trend over the last number of years for operators to move away from traditional methods of connecting pipework due to – safety concerns, high associated costs, and availability of skilled trades for traditional methods of pipework fabrication.
The mechanical connector has been around for an age, they come in all shapes and sizes with their various advantages but the age old trusted is the traditional weld neck flange. One of the key obstacles associated with flanged connections is their inclination
to leak over time. This can lead to Technical Safety assessments and the case for area’s to be re-classified. The challenge then becomes how do operators keep a “cold work solution” whilst eliminating the baggage of potential leaks from flanges – Lokring Coupling to the rescue!!!
A Lokring coupling is the only mechanical joint on the market today that is equivalent to a coded butt-weld and is capable of being used in place of two flanges without the need to derate the classification of a zone from a “fully welded” system. The cost/time benefit of using a Lokring coupling over two flanged joints is generally well established within industry.
In 2016 an offshore operator in the North Sea requested assistance from a leading global energy consultancy group to carry out an assessment of Lokring with the view of using the weld equivalent technology on a fuel gas

application offshore. This document was used to fully back up claims made by Lokring, and as justification to carry out the works. Direct quote from the document – “Lokring could be viewed as equivalent to welded pipework, for fuel gas, keeping the area classification as a non-hazardous zone.”
