In addition to our renowned wellhead pressure and temperature sensors, available both as single and dual units, we also offer a wide assortment of proven and tested instruments for monitoring the conditions of subsea operations. Matre subsea sensors were first used in the TOGI (Troll-Oseberg Gas Injection) project in 1988, performing superbly throughout the 23-year lifespan of the subsea installation. Our high-quality sensors and transmitters, which also include various sensing products for numerous applications, ensure reliable measurements throughout the lifetime of a subsea field

6 Subsea systems Enabling large-scale subsea processing Dependable power supply and distribution is vital for subsea production facilities. Siemens has the know-how and ability to configure complex power transmissions to multiple subsea functions. We offer a sizeable assortment of specialized systems for reliably supplying electricity to numerous consumers across the seabed and downhole ESPs from an onshore power plant or platform. As operators are faced with ever stricter health, safety, security and environmental (HSSE) guidelines, control and surveillance play an increasingly important role for subsea oil and gas processing. Reliably monitoring well performance is crucial for ensuring maximum availability and oil recovery as well as for cost savings, maintenance reduction and system life extension. Siemens has a variety of subsea systems and solutions for condition, performance and environmental monitoring as well as operation control and communication, including direct electric heating (DEH) power systems designed to prevent hydrate formation in pipelines. With our long-standing expertise in power, distribution and control technology, we are able to provide customers with smart systems specifically tailored to their subsea applications and demands. We can assist you with everything from the studies, design, procurement and assembly to the testing and installation

7 Powering installations on the seabed down to 3,000 meters and more With the Siemens Subsea Power Grid, a supply and distribution system, we are combining our high R&D focus and broad subsea power concept experience with our extensive marinization expertise. Currently undergoing the detail design and test phase, it incorporates proven high-quality Siemens industrial components, including subsea Subsea switchgear The subsea switchgear has a modular design. Its main bus bars, wet-mate connectors and measuring transformers are housed in the fluid-filled and pressurized base module. transformers, switchgear and variable-speed drives. All power components can be installed on a common structure located on the seabed. As such, the Siemens Subsea Power Grid marks another milestone in powering large-scale seabed processing facilities. Subsea transformers The step-down transformer is the main interface between the subsea transmission line and the power distribution. As a hermetically sealed, fluid-filled and pressure-compensated unit transformer for variablespeed drive of pump motors, it enables step down to a wide range of consumers as well as longer step-outs. Its natural convection cooling reduces maintenance requirements. Variable-speed drives The variable-speed drive (VSD) features a fault-tolerant multi-cell topology with built-in component redundancy. Designed specifically for sea floor operation, its fluid-filled enclosure and all power electronics can be exposed to full pressure, thereby reducing maintenance requirements

8 Electrical heating for flowline control and installation monitoring Operators face several challenges the need to enhance recovery, follow strict regulations as well as comply with health, safety, security and environmental (HSSE) requirements.
