Supplies at Work: Honeywell supplies control and safety systems for RWE Dea's North Sea platforms

Honeywell ( has been selected by RWE Dea to design and install the Integrated Control and Safety Systems (ICSS) at both of RWE Dea's North Sea platforms, Clipper South and Breagh A. The projects will see Honeywell Process Solutions' (HPS) ICSS implemented at the two RWE Dea's North Sea platforms.

The Breagh field is located in the Southern North Sea, approximately 86km from RWE Dea UK's Cavendish gas field. The resources of Breagh gas field, together with its surrounding fields, constitute one of the largest undeveloped natural gas discoveries in the Southern North Sea. The Clipper South field also lies in the Southern North Sea. Production is expected to start in both locations in 2012.

Supplies at Work: Siemens receives order for compressor train for PTA plant in Saudi Arabia

Siemens Energy ( has received an order for the supply of a new compressor train for expansion of the Ibn Rushd PTA (purified terephthalic acid) plant in Saudi-Arabia. Purchaser is Taiwan's CTCI Corporation, an engineering, procurement and construction (EPC) company in Taiwan. End customer is the Saudi Basic Industries Corporation (SABIC,, a producer of chemicals, fertilizers, plastics and metals.

The compressor train will be delivered in May 2012 to the plant in Yanbu' al Bahr, a major Red Sea port in Saudi Arabia. In addition, Siemens will also modernize the plant's existing PTA compressor train.

The new compressor train consists of a gear-type air compressor, an expander, a steam turbine and a motor with auxiliaries and control systems. The equipment is designed for the production of 350,000 tpa of PTA, which represents a duplication of the currently installed capacity at the Yanbu site. PTA is a white granulate. It is mainly used for polyester yarn for clothing, but is also used in tire cord and as a resin in plastic (PET) bottle molding.

Supplies at Work: ABB controls world’s first zero-emissions ‘natural cooling’ data center

Located in Iceland midway between Europe and North America, the Thor Data Center is a hosting and cloud storage services center situated close to the island’s capital, Reykjavik.

The facility recently opened its first 40-foot data storage container and has a second under delivery. Both containers use new cooling technology developed by Spain-based AST Modular, which enables Thor DC to operate with a power usage effectiveness (PUE) ratio of only 1.07 – probably the lowest on record.

Known as modular natural free cooling, the patented technology uses the naturally cool outside air of the Icelandic climate to maintain the correct operating temperature and humidity level inside the sensitive data storage containers.

This, and the fact that the electricity supplied to the center comes from renewable geothermal or hydropower sources, means that Thor DC offers its customers a green data storage environment with zero carbon footprint, while benefiting itself from the ultra-energy efficient ‘natural and free’ cooling technology of the AST Modular concept.
Monitoring and controlling the critical parameters in each data storage container are two ABB AC500 programmable logic controllers (PLCs).

The ABB ( solution consists of one active and one redundant AC500 PLC. The active PLC measures all the critical parameters in the data center – temperature, humidity, fan speed, energy consumption, fire and water detection, etc – to ensure that operating conditions within the container remain constantly optimal. The redundant PLC takes over control of the data center within just 20 milliseconds in the unlikely event of the active PLC failing.

The data measured and monitored by the AC500 isthen transferred to a SCADA system and monitored from the AST Modular control room in Barcelona, Spain. The data can be accessed and alarms received by iPads, iPhones and other tablets and mobile devices.
AST Modular selected the ABB solution for its modularity, robustness and ability to provide all the required functionality necessary to ensure that the data storage centers can operate at exceptional levels of reliability and availability. ABB’s global footprint and ability to provide support and service all over the world were also vital to AST Modular’s requirements.
