Osbit has successfully completed and loaded out US$3.96 million (£3 million) worth of well intervention equipment to Helix Energy Solutions, for installation in Schiedam on Helix’s chartered Siem Helix 1 vessel.
The multi-million dollar deliveries are a major milestone in a series of projects awarded to Osbit last year, to supply around $14.5 million (£11 million) worth of equipment for the Siem Helix 1, Siem Helix 2 and Q7000 vessels.
The equipment, weighing over 300-tonne in total, consists of a BOP (blowout preventer) maintenance and storage tower, intervention tension frame (ITF), and moveable deck. The three systems will be installed on to Siem Helix 1 this week, ahead of the vessel being deployed in Brazil on a long term well intervention services charter for Petrobras. A second suite of identical systems will follow later in the year for the Siem Helix 2 vessel.
The maintenance tower offers a safe environment to assemble and maintain subsea equipment, incorporating a 125-tonne capacity lifting system to enable progressive assembly of stack modules.
The ITFs represents a significant advance in safety and operability of coiled tubing and wireline operations on the vessels. Developed in close collaboration with Helix, each ITF provides a safer working environment from which coiled tubing and wireline operations can be conducted. The ITF has three platform levels for personnel to conduct operations using dedicated skidding systems.
Continuous safe access to the ITF is possible via telescopic gangway, also designed and built by Northumberland-based Osbit. The gangway links the ITF to the maintenance tower and removes the need for engineers to use rope access methods to operate the well intervention systems mounted within the ITF.
The moveable deck, which will be installed adjacently to the maintenance tower, is a specialized mezzanine deck to provide an additional support and work area over the vessel’s moon pool.
