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.
Each 100 tonne ITF system is over 20 metres high and provides a safer working environment for well intervention work, including coiled tubing and wire line operations.
The walk-to-work systems enhance safer working conditions by removing the need for engineers to use rope access systems between the ITF and maintenance tower. This is a substantial step forward in safe vessel operations. Each access system 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 using the skills and services of their local supply chain.
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 2vessels. 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.
