OSBIT’s ITF provides safe and efficient environment for well intervention

The Helix Intervention Tension Frame (ITF) was implemented after Helix Energy Solutions approached OSBIT with a well intervention problem; how to deploy tools safely from a vessel.

OSBIT responded with a tension frame that is constrained onto a vessel so that it slides only vertically with the craft allowing them to establish a walk-to-work system and allowing a relatively large ITF compared to the vessel. The ITF has three platform levels, is accessible via a telescopic gangway and removes the need for engineers to use rope access systems. This means that from a relatively small vessel, a suite of tools can be exchanged without having to come off the well in addition to the swift manoeuvring of personnel.

With the ITF, Helix vessels productivity is greatly enhanced, with crews able to quickly access the wells, use the tools they have, and move from well to well and tooling suite to tooling suite safely and effectively. This ensures that the right people are at the right equipment at the right time, and that maintenance can be carried out as swiftly as possible.

In use on Helix Siem vessels in Brazil the integrated system is field tested, with noticeable benefits such as reducing the time taken to switch between wireline and coil tubing operations (and back again) from days to just a few hours. It has also had a marked improvement on safety with the Siem Helix 2 recently completing 500 days without an LTI.

David Carr, Senior Vice-President of International Development at Helix Energy Solutions commented, “The three ITFs that were built for us by OSBIT have had an outsize effect on increasing the safety and efficiency of our most recent three vessels. Just being able to switch operational modes to go from wireline to coil tubing in a manner of hours is saving our customers significant rig time. More importantly they provide a safe compensated platform for our crews to work at height and because of that we have been able to completely eliminate man riding from these vessels. We are extremely happy with the safe working environment that the ITF brings to Helix.”

For the ITF project, OSBIT was shortlisted for Most Innovative Solution at the OWI Global Awards 2020, capping a positive year for the company despite the pandemic. At the start of the year, OSBIT was awarded a contract by FTAI Ocean, a subsidiary of Fortress Transportation and Infrastructure Investors LLC, to develop and construct a new well intervention tower system and has also recently appointed Robbie Blakeman as joint managing director to reflect the ambitions of the company as it seeks to continue its success and growth into 2021.
