Siemens has signed a development agreement to promote an open standard Subsea Control Systems for Saipem's Subsea Bus architecture based on Siemens Subsea DigiGrid.

Under the agreement, Siemens' subsea unit will assist Saipem in developing Saipem Subsea Bus architecture.

The collaboration will develop Siemens Subsea DigiGrid digitalisation, control and communication portfolio into a customised subsea control system.

This system will form one of the prominent elements of Saipem’s technology platform for subsea processing systems.

Saipem CEO Stefano Cao said: “This technology cooperation agreement with Siemens marks a further step for Saipem along the road to the development of Saipem’s Subsea Processing Systems.

"The open framework architecture will facilitate the unlocking of the supply chain and the achievement of cost savings through an innovative technological approach."

The Saipem Subsea Bus is an extendable open framework platform of software and hardware components.

Components include development and debugging tools to provide full support and integrate into all subsea applications.

Siemens Subsea CEO Frode Tobiassen said: "In Saipem, we have found a partner who is as passionate as Siemens about introducing Open Framework All-Electric systems in order to facilitate flexible digitalisation and automation solutions to the subsea industry."

The combined system will be capable of controlling an ‘All Electric’ configuration.

This configuration is suited for subsea fields with long-distances between wells and host facility, avoiding costly hydraulic umbilical cables while leveraging distributed architectures with high-performing control units to support subsea technology applications such as seawater treatment and separation.
