Standard Subsea Connection Systems Integrated offshore offering for reliable, high-quality, and capitalefficient performance Standard Subsea Connection Systems Through standardized processes, common core components, and qualified, field-proven assemblies, OneSubsea can deliver standard subsea connection systems anywhere globally within 6 months. These highly configurable solutions are designed to bring greater efficiency and reliability to subsea operations, enabling project viability and helping you meet a range of functionality requirements while driving down capex. Advantages Flexible Functionality Versatile and efficient OneSubsea clamp systems (OCSs) ensure that there is a connection solution for every application. ■■ High load capacity ■■ Accommodation of rigid, flexible, or multibore jumper configurations ■■ Proprietary dual metal gasket (DMG) ■■ Compact design that reduces weight and cost of structures ■■ Subsea seal replacement and hub cleaning ability ■■ Reduced jumper installation time ■■ Backseat testing capability ■■ ROV fly-to-place tooling that eliminates the use of downline ■■ Wet parking capability ■■ In situ insulation capability The standard connection system is built from a suite of preauthored quality control, material, welding, and coating specifications that simplify and expedite our execution processes. OneSubsea works with approved vendors to ensure that they can manufacture the required components, enabling high confidence in quality and lead time. Quality Control Materials The QC requirements for our connection systems are in accordance with API Specifications 6A and 17D. Facilities are certified per API Q1, strategic subcontractors are certified to ISO 9001, and body forgings are certified to DNV 3.2. This approach facilitates preengineering of materials, which enables preordering and, in certain cases, stocking them to secure lead time and protect schedule. Surveillance by customers is available during factory-acceptance testing. All material specifications used conform to API 6A and API 17D and were chosen on a component-by-component basis. Pressurecontaining components additionally conform to DNV GL recommended practices (RP) for steel forgings for subsea applications (DNVGL-RP-0034). A range of standardized material options is available based on component criticality, manufacturability, and environmental compatibility. Welding Coating Our welding procedure for subsea connection systems conforms to API 6A, ASME IX, ASME B31.3, ASME B31.8, and NACE MR0175 / ISO 15156. Adhering to proven, tested, and repeatable processes enables OneSubsea to There is one overall coating procedure comprising two preferred subsea coating options—one for temperatures up to 122 degF [50 degC] and one high-temperature system for up to 302 degF [150 degC]. The standard coating specification gives the requirements for surface preparation, selection of coating materials, application procedures, and inspection of protective coatings to be applied on the standard connection systems. ■■ standardize welding specifications within and across product lines and vendors ■■ provide a superior engineering design that meets or exceeds industry specifications at a lower cost ■■ deliver increased value by enhancing the product without incurring added costs.
