Parker Instrumentation’s valves, manifolds and tube fittings have helped Tyco Fire & Integrated Solutions to build compact Topside Umbilical Termination Units (TUTUs) for a North African offshore project. The TUTUs are destined for an oil and gas platform, and will provide the operator with a means of isolating the hydraulic and chemical injection services to the well. To help minimize the equipment size, Parker Instrumentation suggested that Tyco use manifolds from its HiPro family for the isolation functions. These components provide the required double-block-and-bleed functionality in a compact, in-line format. Parker also supplied Tyco with the additional valve components needed for the TUTU cabinets – including high-integrity fire-safe valves for the methanol injection lines – simplifying project execution. The pressure ratings required for this offshore platform project are up to 517bar. For the critical isolation points in this equipment, Parker’s HiPro manifolds provide a double ball valve assembly inside a single-piece in-line body, with a needle valve assembly for bleeding. Rated at up to 689bar, the manifolds were designed expressly for limited space applications requiring lower weight, and provide a particularly compact solution for offshore projects such as TUTUs. Before shipping the equipment, Tyco tests the integrity of each flow line assembly to pressures that are at least 50% higher than the maximum working pressure.
