Products and systems for deepwater oil and gas developments

The future of oil and gas recovery involves accessing increasingly complex reserves. It involves cost-efficient subsea processing developments, especially for long step-outs, marginal and dispersed fields frequently located in deep and ultra-deep waters. It involves advanced supporting power supply and distribution technology.

As the technology leader for land-based power generation, transmission, distribution, drives and automation, Siemens supplies complete in-field subsea distribution systems, with the expertise and capabilities for configuring complex power transmission to multiple subsea consumers.

The Siemens subsea products and systems’ portfolio covers a broad spectrum of applications, and includes market-leading brands such as Tronic, Matre and Bennex. Going far beyond power and distribution, the portfolio comprises everything from pioneering technologies for subsea control and surveillance to exemplary service and support based on extensive expertise. These are reflected in the quality of Siemens subsea solutions and in the innovation, excellence and concern for safety and sustainability.

Making the right connection

The reliable Tronic line of DigiTRON, SpecTRON, FoeTRON and ElecTRON products provides electrical and fiber-optic connector systems for subsea power and communications. The company installed in 1994 the world’s first subsea electrical submersible pump (ESP) system with wet-mate connectors to power a downhole pump. Since then, ESPs for subsea wells have become a widely accepted solution.

Besides that, with a solutions line-up that comprises subsea distribution units, a high-power changeover switch as well as pressure-compensated electrical, fibre-optic and hydraulic connectors and jumpers, Siemens has the capabilities needed for safe and reliable subsea power and signal distribution.

Concerning sensor components, the Matre sensors and transmitters have been delivering excellent performance with a high level of dependability for over 20 years. In addition to the renowned wellhead pressure and temperature sensors, available both as single and dual units, Siemens also offers a wide range of proven and tested instruments for monitoring the conditions of subsea operations.

Subsea systems

Dependable power supply and distribution is vital for subsea production facilities. 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. With a long-standing expertise in power, distribution and control technology, Siemens is able to provide customers with smart systems specifically tailored to their subsea applications and demands, and assist the customers with everything from the studies, design, procurement and assembly to the testing and installation.

With the Subsea Power Grid, a supply and distribution system, Siemens is combining the high Research & Development focus and broad subsea power concept experience. The solutions incorporate the industrial components, including subsea 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.

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 HSSE requirements. There is an ever greater demand for control and surveillance of assets and the environment to ensure that subsea oil and gas operations are successful. With the Siemens subsea monitoring experience, our topside process control as well as industrial IT and database systems, can offer superb assistance in this area.

On the other hand, our broad subsea surveillance and controls portfolio covers everything from well performance and gas leak detection to reservoir, integrated environmental and condition monitoring – including seabed seismic and oceanology applications.

Lifecycle management

Subsea oil and gas recovery comes with many challenges. In order to adequately meet steadily growing customer demands, to optimise operational efficiency, extend field life and increase output, Siemens fully backs its commitments with a variety of service support offers – at every phase of the development. Through a network of factories and service centers strategically located throughout the world, Siemens Subsea offers flexible maintenance and service for the entire subsea product portfolio - connectors, sensors, systems, and distribution components, when and where it is needed.

Subsea Service Centres in Africa

Angola

The first Subsea Service Centre set up in the African Continent is based in Angola. While working closely with the European hubs in Norway and United Kingdom (UK), it is an example of the company's engagement towards this critical sector for the Angolan economic-financial system. With a local team of skilled engineers trained and certified at the production factory in Ulverston (UK)and with its own facilities for tooling and testing equipment in Luanda and Lobito, the set up in Angola has a growing potential. Focused on operators (e.g. BP, ENI, TOTAL, etc.) and EPCs (e.g. Angoflex, Aker Solutions, GE, TechnipFMC, etc.), it has supported several projects in Block 15, Block 15/06, Block 17, Block 18, Block 31 and Block 32 contributing to the reduction of project CAPEX and lead time. To better support the several customers it has in this area, Siemens Angola is certified for its Quality, Environment, Health and Safety systems. The company is also investing in the training and education of local resources through several programs such as the “Training all over” initiative. In the midst of this program, Siemens Angola already trained its employees in countries such as Germany, United States of America, Norway or Switzerland. The unit in Angola is aimed for growth locally but also to expand the service support to overseas within the region.

Nigeria

In Nigeria, Siemens has been highly committed in supporting GE on Shell’s Bonga project. There has been a number of installations of Tronic connectors carried at the customer site which is located at Onne in South Nigeria. FASL is another customer being supported on termination of free issued connectors offshore Lagos (OML 113).  There are also offshore activities for Halliburton at Takoradi, Ghana. The existing service center is located in Port Harcourt.
