The task: enhancing oil and gas recovery in challenging environments
The future of oil and gas recovery involves accessing increasingly complex reserves frequently located in deep and ultra-deep waters. Subsea processing opens the door to more cost-efficient developments – especially for long step-outs, and for marginal and dispersed fields. It requires enabling systems to improve recovery rates and minimize operating costs. Furthermore, it involves advanced supporting power supply and distribution technology.
Our goal: making subsea field developments technologically and economically viable
Our subsea products and systems portfolio covers a broad spectrum of applications. Going far beyond power and distribution, it comprises everything from pioneering technologies for subsea control and surveillance to exemplary service and support based on extensive marinization expertise. As a result, we are able to provide answers over the entire life of the field.
Our offer: products, systems and lifecycle services for oil and gas developments on the seabed
Siemens has successfully developed and tested a new cost-efficient product for better subsea Ethernet communication. The Advanced Converter & Switch (ACS) is making it possible to communicate at higher data rates and over longer lengths, then with the current electrical distribution technology. The ACS increases precision and effectiveness of subsea communication. This transparent communication solution can be used for connecting to existing subsea fields, for field extensions or for new developments. It is a simple and cost-effective solution for both brownfield and greenfield applications of subsea Ethernet.
Direct Electrical Heating power supply systems: prevention of hydrate formation in subsea pipelines
Siemens’ direct electrical heating (DEH) power systems help prevent wax and hydrate formation and support a consistent flow of hydrocarbons despite challenging fluid characteristics and temperature conditions on the seabed.
They allow for OPEX savings through reduced chemical injection and dumping into the sea, in addition to low CAPEX and maintenance costs while also avoiding depressurization during shutdown.
Subsea hydraulic power unit (SHPU)
Combining our electrical and hydraulic system expertise, we deliver hydraulic power units for permanent subsea installation. As an alternative to umbilical replacement, the SHPU can be operated in several ways – for example, as a repair unit for subsea hydraulic supply failures such as leakage or blockage that may result in a well production stop. Or as a building block in green field hydraulic infrastructure developments – a particularly viable alternative for long step-outs. With its low peak power consumption, the SHPU helps to maximize the utilization of the subsea electrical infrastructure and standard interfaces for universal application.
