Overseas Consultants LTD Projects

Some of the projects OCL and its staff have worked on are:

• BTC Pipeline Project, Azerbaijan, Georgia, & Turkey
  The start of the BTC (Baku, Tbilisi, Ceyhan) pipeline is at the Sangachal terminal near Baku in Azerbaijan, which receives all the oil from the Azeri, Chirag and Gunashli (ACG) offshore oilfields in the Caspian (the ABB System 800xA control system for the entire pipeline is also situated here). The terminus of the pipeline is at a new marine terminal at Ceyhan in Turkey, where crude oil transportation tankers will be loaded. It has been estimated that the ACG oil fields have reserves in excess of 5.4 billion barrels. The ACG fields are being developed by the Azerbaijan International Operating Company (AIOC), a subsidiary of BP. OCL Staff are working with ABB, installing and commissioning all block valve sites in all three countries. The block valve controllers are based on ABB's flag-ship System 800xA 800M controllers, connected via a fibre-optic backbone that runs the length of the 1770KM pipeline to the ABB System 800xA DCS systems at Baku and Ceyhan.
  
  
• Karachaganak Oil & Gas Project, Kazakhstan
  The Karachaganak oil field supplies high quality oil condensate to worldwide markets via it's newly purpose built export pipeline, running from the Karachaganak site to the port of Atyrau on the Caspian Sea, and also into Orenburg, Russia. During this two year commissioning project, OCL staff commissioned the Early Oil Satellite (EOPS) SCADA system, comprising of a number of oil wells and two manifolds. In addition to commissioning the Serck SCX5 based SCADA/telemetry system, which comprised Proteus 2000M outstations running at temperatures as low as -40 degrees centigrade, OCL staff also commissioned the fibre optic backbone between the dual redundant SCX5 servers and the RTU's. Additionally, OCL staff were on hand to assist with commissioning the field instrumentation at the well and manifold sites, including pressure, temperature and flow sensors, and gas detection devices. OCL Staff later moved on to complete outstanding commissioning works on the Unit 2 oil and gas re-injection well RTU's and SCX SCADA servers. Finally, OCL staff, subcontracted to Invensys, took on the maintenance of the complete field, comprising over 60 wells, and three separate dual-redundant SCX SCADA Server installations.
  
  
• Environment Agency River Monitoring Project, UK
  OCL Staff supplied custom written software for the Environment Agency project, allowing the Environment Agencies ancient Argus based SCADA system to communicate with Serck Controls' latest, state-of-the-art SCX6 SCADA technology suite. The software takes data from the Argus system using the Environment Agencies proprietary, yet obsolete Microport Protocol and supplies the data in SQL form to SCX6. The project allows the Environment Agency to monitor river levels in real time, with a view to providing better flood-warning capabilities. The upgrade to an SCX based system has allowed the Environment Agency to move away from bespoke software and protocols and leverage the full benefit of standard, globally recognized technologies, such as XML, SQL, and COM.
  
  
• GIDP Project, Bangladesh
  The Gas Infrastructure Development Project, based in Dhaka, Bangladesh is a project funded by the UK Department for International Development. The project distributes gas, tapped from pre-existing, refurbished wells located mainly in the North areas of the country, throughout Bangladesh. Based on triple redundant Serck SCX5 SCADA technology, and Serck Proteus 2000M RTU's, the SCADA System affords real-time monitoring and control of the wells and the pipeline. RTU Communications are packet radio based. Communications infrastructure is microwave based, including multiplexed telemetry, IP network traffic, telephone, and voice radio traffic.
  
  
• OGD2, Abu Dhabi, United Arab Emirates
  OGD2 is an On Shore Gas processing plant, located in desert of Abu Dhabi in the United Arab Emirates. A number of solar powered Serck RTU's controlling the gas well heads and manifolds communicate with a dual-redundant Serck Controls SCX5 SCADA system and offers real-time control and monitoring of both the wells, and the export pipeline to the city. RTU communications are based on MDS packet radio systems.
