Pipeline and pump station automation

BP OIL UK – WALTON WEIR SCADA

Cetix was contracted by BPA (working for Air BP) to provide the control and monitoring (SCADA) system for a new pump station at the Walton Weir fuel storage terminal.  The pump station was required to increase the flow rate on the London Airport Pipelines (LAP) network between Walton and the Southern Fuel Receipt Facility (SFRF) at Heathrow Airport.  New pumps were installed at Walton Pump Station (duty and standby) together with the associated controls, monitoring and communications infrastructure.

The SCADA system was required to provide all necessary monitoring and control of the new Pump Station facilities and at other sites associated with the LAP.  Local control panels (LCP) and Man Machine Interface (MMI) PC’s were provided at Walton and SFRF.  Simple LCPs were located at the Sunbury Lane and North River Crossing sites.

Under normal operating conditions, the system will be controlled from a new SCADA Master Station located at Sunbury Lane Pipeline Control Centre.  In the event of a major failure at Sunbury Lane, the operations staff at either the Pump Station or SFRF will be able to control the entire system from that location.

Energy From Waste

FCC ENVIRONMENT – EASTCROFT INCINERATOR

FCC Environment, formerly Waste Recycling Group, has operated the Eastcroft Energy from Waste Facility (EfW) in Nottingham since 1998.

The facility takes around 160,000 tonnes of non-hazardous waste from households and businesses within Nottingham and the wider county for treatment by high temperature incineration and energy recovery. Residual waste is brought to the facility after recyclable materials have been separated out either at home, household waste recycling centres or other waste recycling and treatment facilities. The use of energy recovery at Eastcroft vastly reduces the amount of waste sent to landfill as well as Nottingham’s reliance on fossil fuels to supply the City’s energy needs.

The energy recovery process at Eastcroft generates steam, which is delivered via a pipeline to EnviroEnergy Limited, a company wholly owned by Nottingham City Council. EnviroEnergy supplies heat to a wide range of customers, including 4,600 domestic premises in the city, as well as public buildings including the Broad Marsh shopping centres, Victoria Baths, Nottingham Trent University’s Newton Building, the Inland Revenue building, the Magistrates Court, Nottingham City Council offices and the National Ice Centre. Any excess steam is also used to generate electricity which powers the facility and is also supplied to many local customers within Nottingham City.

Through ABB Environmental, Cetix Limited was contracted to design and install a new integrated control and data management system for the new and existing plant.

The Cetix Limited solution was to provide a networked SCADA (Supervisory Control and Data Acquisition) System based upon products from Rockwell Automation. The original system comprised Control Desk Computers, 4-off PLC 5/40 Programmable Controllers and a ControlView graphical interface. The total I/O count was approximately 1,700. These 5/40 PLC’s have recently been successfully upgraded to ControlLogix.

Cetix Limited also supplied the Motor Control Centres, Electrical Switchgear and Local Control Panels, as well as having responsibility for the electrical installation and site cabling.

Cetix Limited upgraded the original Rockwell ControlView system to RS View 32.

Cetix Limited has also supplied a site wide Ethernet IP based CCTV system.

Safety Systems

BG GROUP – NORTH EVEREST & LOMOND

Cetix Ltd, a long established and well-known System Integrator, originally supplied the Emergency Shutdown and HVAC Systems for the Everest and Lomond (Erskine) Platforms operating in block numbers 21/22/23 of the UK sector of the North Sea.

The Cetix Ltd ESD equipment is basically quantified as a total of four networked TMR systems, with associated SCADA Workstations networked together.  The Cetix Ltd HVAC system is controlled utilising Modicon equipment.

Cetix Ltd control a Bonded Store area, which is located at the Rotherham premises, for the ESD / HVAC equipment on the Lomond and North Everest Platforms.

Both Everest & Lomond started production in 1993 and achieved their nominal plateau production rates of 200msc in 1997.

In 1997 additional dedicated processing and compression facilities, the Erskine production Module (EPM), were added to the Lomond Platform.

Cetix Ltd provides ongoing 24hr support and maintenance for the Lomond and North Everest platforms.

Since the commissioning of the original systems in the early 90’s Cetix Ltd has provided engineering services throughout the life of the platforms and has successfully implemented numerous changes and upgrades to the systems.
