A new fourth NGL Train at Ruwais was installed under this project to process a portion of the NGL products from AGD-0, BAB, Bu Hasa and Habshan (excluding OGD-III).
The fourth NGL fractionation plant produces four products: raw ethane, propane, butane and paraffinic naphta hydrocarbons, and liquid sulphur. The capacity of Train 4 is approximately 27,000 TPD of NGL/LPG. A new 30 PD sulphur recovery unit was installed to handle acid gas flows from Train 4 and acid gas from Trains 1, 2 or 3 and vice versa to meet ADNOC’s environmental policy.
The project includes a main processing plant fractionation refrigeration, mole sieves treating, DEO treating, sulphur recovery unit and storage area civil works.
The Shuweihat S1 1500 MW combined cycle power plant is currently one of the world’s largest combined power and water plant complexes, delivering 1500 MW of power to the emirate of Abu Dhabi.
The plant consists of five Siemens v94.3A gas turbines, two 251 MW steam turbines, seven electrical generators and all the ancillary systems. It is linked to a seawater desalination facility which is supplied with steam from the turbines.
This project was an Independent Water and Power Project commissioned on a Build Operate transfer (BOT) basis.
ACC was the civil works and structural steel contractor on this 50 MIGD desalination plant, which was completed in 2001. Complementing the Taweelah A2 Power Plant, the desalination plant was awarded as a BOT contract and executed on a fast-track basis.
Water production is achieved from four MSF distillers, each weighing 3,500 tons and measuring 90 m long by 30 m wide, fired by waste heat from the gas and steam turbines. Each distiller has a capacity of 12.5 MIG per day.
The scope of work included civil works for the four MSF distillers, a switchgear building (for desalination and remineralisation plants), a chlorination building, 4 large potable water storage tanks, a potable water pump house, a 1.1 Km discharge culvert and other related structures.
ACC was the civil works and structural steel contractor on this 750MW power plant, completed in August 2001.
The project was unique in nature since it was the first Build Operate Transfer (BOT) project in the UAE and was executed on a fast-track basis due to the commitment made by Abu Dhabi Water and Electricity Authority to increase power output.
The project is now a benchmark for Independent Power and Water Projects (IWPP) projects in the Gulf.
The scope included civil works for the covered and cladded power island (gas & steam turbine building), transformers, boilers, heat recovery steam generators, control building, liquid fuel tank and other related structures.
Emirates Steel Industries has established a steel plant in the Industrial City of Mussafah in the Emirate of Abu Dhabi to produce 1.4 million tonnes per year of steel billets.
To enable the import of the iron ore, a jetty has been constructed in the Mussafah Channel where the ore material will be discharged from barges into a hopper and onto a conveyor system leading to the plant.
The Jetty Construction package included the construction of a 60 m long blockwork quay wall including fenders and bollards; construction of blockwork mooring and breasting dolphins; dredging of 180,000 m³ for navigation and berthing of barges; fabrication and erection of a 200 m long structural steel catwalk; construction of bored piled hopper foundations; supply and installation of a 30 m high light mast and the construction of rock revetment and pavement.
ACC was subcontracted for the civil, structural, building and external works and the outfall channel for both the power and desalination elements at the Umm al Nar Independent Water and Power Plant.
The IWPP involved decommissioning the existing 850MW of generating capacity at the site and installing 1550MW of new build to be constructed by Toshiba and based on Frame 9 gas turbines from the US’ General Electric Power Systems (GE). In addition, 25 million gallons a day of new multi-stage flash capacity was added by Japan’s Hitachi Zosen Corporation to the plant’s 70 million gallons a day of recently installed capacity.
ACC was the civil and structural steel contracting partner for Doosan Heavy Industries for the Umm Al Nar desalination plant, which was completed in 2002.
The plant is able to produce 62.5 MIGD and was built on a fast-track basis. Out of a total of 65,000 m3 of concrete, ACC managed to pour 50,000 m3 of concrete in less than five months.
The project consisted of five distillers, each measuring 90 m long by 30 m, five low pressure boilers, four 75 m diameter water tanks, a 1.1 km discharge culvert, an outlet structure, 5 km roadworks, a remineralisation plant, a potable water pump station and 31 other plant structures.
The Ministry of Presidential Affairs Abu Dhabi (MOPA) general facility enhancement, ACC carried out works to realign the existing shore by constructing a reinforced concrete seawall of approximately 1.65 km long. This included enabling works; seawall construction; demolishing existing groynes and constructing new groynes and revetment; constructing reinforced beach steps, guard tower raft foundations and walls and constructing new beaches.
This project was one of the sections for the transfer scheme of water from the Shuweihat Independent Power and Water Plant to the UAE capital, Abu Dhabi.
The project consisted of 6 water tanks, a pumping station building, a switchgear building, a chlorination building and all other relevant infrastructures and facilities such as underground piping, truss blocks, roads, cable trenches, concrete fence and security building.
