3Control systems: the next generation

Control systems

Aker Solutions is one of the leading suppliers of fully integrated subsea control systems. Our new generation of control systems are open, reliable, robust and built upon commercially available building blocks.

Our systems come together under a concept known as SubseaWeb. They rely on communications networks and open data management channels that are designed to meet challenges posed by the subsea environment. We guarantee flexibility and reliability, and by working in partnership with our customers we deliver technologies that realise the full potential of the field.

We have installed over 900 production control systems worldwide since our first installation in the mid 1970s.To this day we maintain our place as market leader. We have a dedicated research, development and engineering team who seek the smartest, most effective solutions, without compromising environment, health, safety or quality.

The projects we undertake have the entire Aker Solutions subsea capabilities at their disposal. We are unique in this respect. Our areas of expertise include:

Feasibility and conceptual studies FEED Detailed engineering Trees and manifolds Subsea processing and boosting Umbilicals Tie-in and connection systems Full aftermarket support

The SubseaWebTMconcept

OPC (OLE for process control connectivity)

OPC is a software architecture that is used to build software components which interoperate regardless of where they are situated.

Open system,open thinking

Historically, subsea control systems used proprietary software and communications protocols that were highly optimised for specific tasks. Due to increased complexity of the systems, and through the availability of higher bandwidth, the time for truly open subsea data systems has arrived.

Building upon our current iCon control system, Aker Solutions has risen to this challenge with SubseaWeb. This architecture concept offers an open, transparent and efficient way to control and monitor the subsea environment through iCon SCU (subsea control unit) or third party topside options. Subsea instrument and down-hole system vendors can gain easy connectivity to the network. Topside users can choose between direct connectivity to the DCS (distributed control system), PLC (programmable logic controller) or stand alone MCS control.

OPC (OLE for process control connectivity) and TCP/IP (transmission control protocol/ internet protocol) running over industrial ethernet are accepted as universal standards. OPC and TCP/IP are the building blocks of SubseaWeb and keep system costs down, while guaranteeing greater networkavailability and reliability.

We believe the use of open and integrated systems architectures increases capability and confirms our commitment to the technology development of our subsea control systems.

Smart solutions

Flexible options: SubseaWebTM

Our flexible solutions allow the customer to deploy various topside options to suit their needs: MCS, PLC control, DCS direct, OPC gateway or IWCU (intervention workover control unit) through SubseaWeb.

Control systems

The demand for subsea intervention and increased oil recovery is growing as the industry is operating in increasingly diverse areas from mature fields, to smaller fields and ultra deepwater environments.

Our intervention workover control system (IWOCS) monitors and controls the deployment, workover and retrieval of subsea production equipment from vessel or platform to subsea.

As well as our excellent track record of delivering subsea control systems, we also offer system and software upgrades. These ugrades increase the control functionality of existing systems that will prolong the life and capabilities of the field.

For example, we offer PodEx technology, which allows operators to extend the instrumentation capabilities of existing systems. Aker Solutions also provide legacy software upgrades from the existing brownfield to the current SMACS6 system. These upgrades extend monitoring capabilities and assist in prolonging the life of field.

Through our innovative solutions and aftermarket services our customers can be assured that we are protecting their investment.

Aker Solutions has an extensive portfolio of products and services to suit the most challenging technological and environmental conditions.

6Industrial ethernet: TCP/IP (transmission control protocol/Internet protocol)

TCP/IP is the de facto standard world-wide for industrial and tele-communications applications.

The benefits

field proven design

Control systems

We pride ourselves on our innovative technology and effective solutions. Clients can rely on our precision in project execution and commitment to achieving the highest standard in quality and on time delivery.

Aker Solutions control systems provide a number of benefits. They are easily configurable, provide deterministic, robust control and open connectivity to trusted standards. We also add value through seamless deployment of our own and third party application software:

Virtual flowmetering Flow assurance Optimisation Asset management Remote access management

Our solutions reduce the project risk and engineering effort. The level of software integration is greatly reduced and we can configure systems at any stage of the asset life.

Our technology can be applied in many ways: Deepwater fields Shallow water Remote and diver installed HP/HT (high pressure/high temperature) HIPPS (high integrity pipeline protection system) Subsea process control systems

Our aftermarket services protect the investment by providing solutions to maintain, support and upgrade existing systems to ensure prolonged life of field.
