Submarino

Los sistemas de producción submarinos se encuentran a diferentes profundidades en el fondo del mar. A medida que se extrae el hidrocarburo, este puede ser enviado a una plataforma de producción en alta mar existente, o por medio de líneas que se pueden atar a las instalaciones en tierra para su procesamiento. Varios tipos de tecnología de equipo de perforación pueden perforar los pozos, y el aceite extraído así como el gas natural los cuales se transportan a la superficie a través de un tubo ascendente. Al igual que en las instalaciones en tierra, las plataformas de producción pueden dar servicio a muchos pozos en un área grande. Los sistemas submarinos extraen y en algunos casos procesan los hidrocarburos antes del transporte.

Yokogawa ofrece soluciones integradas de control y monitoreo que maximizan la productividad del submarino, de la marina, y las operaciones en cubierta mientras se mantienen en un ambiente seguro.

Subsea developments continue to be a prominent part of operators overall asset allocation as offshore leases continue to be available and become financially viable. Traditionally, the subsea controls market is conservative toward the adoption of new technologies, justifiably so due to the potential financial risk of failure in any new solutions. The harsh operating conditions and high cost of subsea operations are balanced with the reward of bringing on line high volume production wells.

The technical, commercial and political conditions which maintained a solution supply chain and inhibited innovation are now collapsing as operators push for standardization. This standardization is also being promoted by the industry trying to achieve greater safety throughout the entire operation.

As part of the ongoing safety improvements, Yokogawa developed the world's first subsea high integrity pressure protection system (HIPPS). A Subsea HIPPS allows the flow lines to be derated which can provide tremendous savings for operators able to use the technology.

HSE Compliance

Subsea HIPPS are primarily to prevent environmental damage from over-pressurized flow lines. Therefore the license issued to the operator may dictate that the system meets IEC-61508/61511 SIL 3. In some instances this has been reduced to SIL 2 relating to the controls vendor using programmable technology for HIPPS. In most locations SIL 3 is dictated and a strong preference for solid state technology or diversity from the control system platform.

The application of high-integrity ESD logic on subsea wellheads provides the potential to eliminate millions of dollars in flow line costs. By ensuring fail-safe overpressure prevention, this pioneering HIPPS innovation provides valuable savings that can transform marginal projects into exploitable opportunities

Subsea Production

Yokogawa's network-based control system and integrated safety system technology provide great visibility, diagnostics, and flexibility. The result is an ultra-reliable solution for subsea wells that reduces the need for maintenance visits providing a lower lifecycle cost.
