OSBIT Power’s Access Systems for Helix’s Well Intervention Vessels

OSBIT Power has completed work on three new walk-to-work access systems to be installed on a trio of new well intervention vessels commissioned by Helix Well Ops U.K.

The completion of the access systems is the first significant milestone in the triple Intervention Tension Frame (ITF) contract awarded to the company in March. This was followed by a second contract win to produce two maintenance towers and moveable decks for two of the same vessels. Together, the two projects form the company’s largest order to date, OSBIT Power said.

Each 100 tonne ITF system is over 20 metres high and extends telescopically through a hydraulic operation to a length of 13.5 metres.

The systems are designed at OSBIT’s head office in Riding Mill, Northumberland and are being fabricated in North East England.

Dr. Tony Trapp, Executive Chairman at OSBIT Power, said: “This is a significant step forward for this project, which is our second order for these vessels and forms the largest combined undertaking in the company’s history. Utilising our experience in delivering walk-to-work access systems, together with our excellent relationships with our suppliers, we have ensured that the overall project remains on time and to budget. We have worked closely with Helix to provide an effective solution that meets the complex operational requirements while significantly reducing cost. This is a major requirement in the current very difficult market conditions resulting from the huge oil price drop over the past 17 months.

Two sets of access systems will be delivered for installation on Helix’s Siem Helix 1 and 2 vessels. The third unit will be shipped to Singapore where Helix’s Q7000 vessel is currently under construction in the Jurong Shipyard.

The ITF, maintenance towers and moveable decks are currently in production at two North East based facilities and will be delivered next year for installation, the company added.

UTC 2017

The subsea industry has, as all other parts of the oil & gas industry, been seriously rattled by the most severe downturn in the hydrocarbon energy era. However, the realization of what hit us and actions to be taken to sustain a healthy and profitable future is still on-going – unfortunately with thousands of colleagues paying the price by losing their job as one of the most severe consequences. At this time, there are signs that we have reached bottom in terms of most industry indicators, but few experts expect a sharp recovery. Many seem to believe that a slow recovery is what the industry needs in order to avoid an unsustainable capacity build-up, as seen in the period after the financial crisis. Considering the uncertainty of what the future will bring, this year’s UTC Program Committee have decided to challenge all of us to present ideas, experiences, technological innovations, business models and execution models for how to shape our subsea future and explain how and why subsea is the future.
UTC welcomes abstracts based on the topics listed below. If selected, please consider writing a paper in addition to the UTC presentation. From 2017, UTC papers will be published in an international database.
