Solutions for Offshore Production & Processing
- Description
- References
Today's oil and gas operators involved in offshore oil and gas production and processing face a host of challenges including remote locations, harsh environments, extreme climates, weight and size constraints. The challenges of offshore production and processing require solutions that are not only robust enough to ensure the day-to-day reliability and availability of equipment in hostile environments, but are also safe, effective, cost-efficient and have minimal environmental impact – over the entire life cycle. In particular, there is a strong demand for power generation and distribution solutions, auxiliary and emergency power units, automation, safety and monitoring systems, switchgear and instrumentation, as well as for broadband telecommunications capabilities, navigation systems and water treatment technologies.
FPSO (Floating Production, Storage and Offloading vessels): effectiveness in remote or deepwater locations
The oil and gas industry exercises strict requirements for safety and reliability nowhere more than in the offshore business. With the move to deeper waters in search for oil and gas, floating production facilities such as semi-submersibles and floating production, storage and offloading vessels (FPSOs) have become a cost-effective alternative to
sea bed pipelines. FPSOs eliminate the need to lay expensive long-distance pipelines from the oil well to an onshore terminal. They can also be used economically in smaller oil fields which can be exhausted in a few years and do not justify the expense of installing a pipeline. Once the field is depleted, the FPSO can be moved to a new location.
Expert, tailored single-source solutions
For over three decades, Siemens has operated as a single source supplier of innovative automation, electrical compression, pumping and power systems tailored for offshore structures. From tension-leg platforms through to semi-submersibles and floating production systems, Siemens can guide its customers through the early-on stages of front-end engineering through design, supply and commissioning to operations and maintenance services. All Siemens technology is API and NACE compliant and skid-mounted, ensuring peace of mind and ease of transportation.
Gas turbines specifically tailored for FPSOs
The Siemens program of lightweight, heavy-duty, industrial gas turbines is the perfect fit for today's FPSOs. Electrical power from the on-board generating plant is fed to medium- and low-voltage networks throughout the vessel using Siemens transformers and distribution switchgear, with safety-critical services backed by uninterruptible power supply (UPS) systems. Direct current supplies for specialized equipment can also be supplied from the Siemens range of equipment, while all major electric drives can be controlled by Siemens motor control centers. Siemens also supplies state-of-the-art automation systems covering process control and safety systems, including emergency shutdown (ESD) and fire and gas (F&G) detection and control. In addition, comprehensive telecommunications equipment from Siemens covers CCTV, video conferencing and entertainment systems, radio and satellite communications, telephone, paging and public address systems, as well as an FPSO’s navigational aids and general administration network.
