EQUIPMENT OVERVIEW SHEET

Shallow Water Production System

13 5/8” 6.5M SVXT

1.0 Technical Summary

GE Oil and Gas offers Subsea Systems designed to operate safely and efficiently in the harsh environment shallow waters of worldwide Oil and Gas Basins. The S-Series System is designed to be deployed using standard offshore Jack-Up Drilling Rigs (JUDR) requiring no major modifications to facilitate the deployment of these Subsea Systems. The systems are installed and tested from the JUDR with no assistance from ROV or Divers. With 20 years of experience operating in harsh environments, the S-Series system design is a benchmark for best installation practices whilst performing shallow water subsea completions. An in-depth understanding of the environmental challenges, weather, sub surface currents, poor visibility, and fishing interaction are fundamental inputs into the system design. The S-Series SVXT positions GE Oil and Gas as market leaders in Shallow Water tree completion and installation technology. GE Oil and Gas provides stock products configured to suit operator requirements allowing shortened lead times, lower installed cost and ease of deployment, unrivalled in today’s shallow water subsea tree market. Fully Integrated Electro Hydraulic (EH) ModPod controls for Subsea and Topsides. All can be installed with readily available rental tool packages. Flow assurance, reliability, hydraulic, electric, riser, conductor and VIV analysis are available as part of the solution.


EQUIPMENT OVERVIEW SHEET Shallow Water Production System

The 13-5/8" 6.5M S-Series SVXT System described in this Equipment Overview provide a summary of the specification, design requirements and operational features, for a low profile 13-5/8" standard S-Series SVXT System and associated tooling. The Tree system is offered as 6,500 psi MWP, Temperature 0 degF – 250 degF, HH Trim Production, EE Trim Annulus, and has a DHPT system feature option.

The S-Series SVXT Tree design and unique tree valve arrangement facilitates a significantly smaller stack-up height. This brings with it far smaller and lighter assemblies that assist installation by JUDR’s. This unique tree valve arrangement utilises the best of field proven technologies from both Vertical and Horizontal tree systems. This aligned with Smart Installation Tooling has removed the need for a Diver or ROV during Installation, making the system safer and more cost effective to install than previously available solutions.

Key Features:

The S-Series SVXT system offered has the following key features compared to existing GE Oil & Gas 13 5/8” Conventional Tree’s.

• Reduced envelope sizes of Tree and WPS saving approximately 20% overall weight in system. Aided by introducing compact actuators which are 34% lighter than previous designs.

• Removal of Lower Master (Manual) and Swab (Hydraulic) valves in production bore, replacing these with crown plugs to give unique barrier philosophy that removes the need for a separate Tree Cap.

• Removal of Hydraulic Tree Cap thus saving equipment and installation time.

• Installation Operations performed via Workover Control System (WOCS) stab plate on the Tree Running Tool (TRT) removing the requirement for an ROV or Diver to remove traditionally made up Junction Plates.

• Use of smart tooling to install the Production Control Bridging Plate whilst running the Corrosion Cap. This activity was traditionally achieved by intervention by Diver or ROV.

• Tree Running Tool contains a shear valve allowing the 7 5/8” landing string to be used as

lubricator string, providing a well control barrier during wireline activities.

• Xmas Tree is provided with GE Oil & Gas fully integrated ModPod Control System minimizing the requirements for third party interfaces.

• ‘Rental’ Smart Tooling packages allow safe and efficient installation of subsea equipment in harsh shallow water environments.

6.0 Modpod Control System

The instrumentation and control system supply on the SVXT reflect the significant experience of GE in this product line.

At the heart of the control system supply is the latest in the

Subsea Control Module (SCM) supply from GE. The ModPod is

utilised to give the appropriate functionality to suit the SVXT

design. The GE ModPod is a highly modular, Multiplexed Electro-

Hydraulic (mux E-H) Subsea Control Module (SCM) for tree mounted

or manifold-mounted applications. It is one of the most

technologically advanced and versatile control system

components available, providing ultra-reliable control and

monitoring of subsea valves and instrumentation.

ModPod incorporates our Proprietary Directional Control Valves

(DCV) to operate the desired valve actuators. The Subsea

Electronics Module (SEM), which is housed within the SCM controls

the DCV in response to a multiplexed electrical or optical

communications signal received from the Topsides Master Control

Station and/or Surface Modem Unit via the subsea umbilical and distribution system.

The Subsea Electronics Module (SEM), known as SemStar5, is capable of remote program download and, together with the Master Control Station (MCS), offers operational parameter storage. Process pressure and temperature sensor and choke position indicator connections are made via CE connectors mounted in the base plate of the pod. All sensor information is routed to the SEM where it is processed and communicated to the topsides MCS. The VetcoGray generic SemStar5 application software is utilised within the SEM module. The software application is developed on a commercially available Real Time Operating System platform in high level languages such as C and is common to all SemStar5 projects. The SEM module is capable of remote program and configuration download.
