STATS Group - Process and Pipeline Integrity Solutions

STATS UK Ltd is a specialist engineering company that operates predominantly in the arena of piping and pipeline integrity and maintenance. We supply a comprehensive range of products and services allowing ongoing piping repair, connection, isolation and testing. The majority of our works are undertaken on mature assets, typically process piping onboard offshore facilities (fixed and floating). We also supply products and services for infield and trunk pipelines both onshore and sub-sea, as well as onshore processing and distribution terminal facilities.

PIPELINE REPAIR CLAMPS

STATS offers a comprehensive range of pipeline repair clamps available for permanent or temporary installation, including ROV installed pipeline clamps. All clamps provide structural and / or pressure containment with single or dual seals. Our repair clamps are designed to suit piping systems and operating parameters from ¾in upwards, including high and low pressures or sour systems. We undertake caisson repair work, clamps, liners and swaged sleeve options available to suit applications. Pinhole repair clamps can be supplied with temporary localised sealing bosses.

CONNECTORS, COUPLINGS AND HOT TAP CLAMPS

STATS maintains a range of products that provide tie-in, connection and modification of existing systems without the need for hot work. Hot tap clamps can provide structural and / or pressure containment, fitted with single or dual seals and off-takes to suit system requirements. We specialise in standardised 150# and 300# flanged connectors and pipe-to-pipe couplings. All of these products are fire-tested and third party approved. Couplings and connectors can be easily fitted and tested, thereby minimising system downtime and enabling rapid re-commissioning of modified pipelines.

AMBIENT TO HIGH PRESSURE PIPELINE ISOLATION

We supply mechanical and chemical isolation devices from ¾in to 48in that are compliant with 1D - 5D bends. Our extensive product range allows for ambient, low, medium and high-pressure pipeline isolations. Gas bags offer ambient isolation with single or dual bag arrangements for downstream or annulus monitoring.

Twin seal annular test tools provide dual seal isolation with downstream or annulus monitoring. Piggable gel plugs are available for ambient isolation and can be dissolved on completion of isolation. DynaCeal gel provides a pumpable gel isolation typically used for valve isolation. Hot tapped isolation can be achieved with STATS dual seal Branch Installed Self Energised Plug (BISEP). A comprehensive range of isolation plugs is supplied for low, medium or high-pressure requirements. Isolation plugs are available for manual, piggable, tethered and remote deployment and operation. The plug actuation system can maintain the lock and seal mechanism independent of the control system, ensuring fail-safe operation.

ANNULAR AND FLANGED TEST TOOLS FOR WELDED JOINTS

Provision of localised test tooling and associated equipment to locally test, modify and repair welded joints. Annular test tools incorporate twin seals, while flange test tools provide localised leak testing from flange gaskets to compression seals. All test tools are supplied for either mechanical or hydraulic actuation. Significant time savings are made when using annular test tools due to the reduction in the amount of pipe work being tested.

SERVICES AND EQUIPMENT

STATS provide highly trained and competent personnel for worldwide field support on all product lines. To compliment our already comprehensive piping products and services STATS offer ‘insitu’ machining services, bolting and ‘internal’ camera inspection services. 'Specialist' hydrocarbon displacement gels can also be supplied for pipeline and process flushing and oil recovery.

PIPELINE CONSTRUCTION EQUIPMENT

Pipeline retrieval tools are supplied to recover damaged or dropped pipelines to pipe lay vessel, with or without de-watering capability. STATS can also provide seal tubes for concrete legs, allowing pipes to be pulled into a dry concrete platform leg.

PROJECT MANAGEMENT - PROJECT AND DESIGN ENGINEERING

STATS Design Engineering department utilises state of the art 3D modeling and Finite Element Analysis in conjunction with engineering calculations and design processes ensuring compliance with Piping and Pipeline codes and standards. As well as supporting standard product lines this capability also supports feasibility studies, product development, R&D and project specific bespoke engineering solutions.

STATS Product lines are controlled through in-house manufacturing and test facilities all of which are subject to rigorous quality control and assurance processes. This is further enhanced by provision of full product trialing and verification programmes. (Including full scale mock ups).

Project management and engineering services are provided to support client needs including turnaround scopes, feasibility studies and contingency planning. Our in-house expertise covers the plant’s life-cycle from precommisioning through to decommissioning and abandonment.

PRODUCTION AND FABRICATION

STATS has a comprehensive machining and fabrication facility and undertakes the majority of our manufacturing and fabrication requirements in-house. These facilities operate on a 24-hour basis as required, allowing for quality of work to be maintained and scheduling to be controlled.
