Abu Dhabi Gas Industries Limited (GASCO), Abu Dhabi Marine Operating Company (ADMA OPCO), and Abu Dhabi Gas Liquefaction Company Ltd (ADGAS) have awarded WorleyParsons six Program Management Consultancy (PMC) contracts with expected total revenue in excess of USD 150 million to manage six engineering, procurement and construction contract (EPC) packages of the Integrated Gas Development (IGD) project.
The packages comprise new Habshan Platform, Ruwais 4th natural gas liquids train, Ruwais storage tanks, Habshan-5 process plant, Habshan-5 utilities and offsites, and Das Island site preparation, process and utilities projects.
WorleyParsons will act on behalf of GASCO, ADMA OPCO and ADGAS by providing services to manage the six EPC contractors to be selected. WorleyParsons’ engagement will span from the EPC pre-award stage through to commissioning and performance testing and handover of the facilities to operations.
Abu Dhabi National Oil Company (ADNOC) is planning to transfer additional high pressure gas from Umm Shaif to Habshan through Das Island, as part of the overall IGD project. The additional gas will be produced from the Umm Shaif Khuff and Umm Shaif Areaj reservoirs. The produced gas will be initially processed on the new Habshan platform and then sent through a new 46’’ main gas line to the new ADGAS facilities on Das Island, being built as part of the onshore scope. There the gas will be conditioned and sent to Habshan through the new 30” pipeline being added as a part of the Offshore Associated Gases (OAG) project. This incremental gas will supplement the high pressure gas already planned to be delivered through the OAG facilities. At Habshan, the gas will be further processed in the OAG facilities and new trains for optimum production of lean gas, which will be sent to the sales gas header, and natural gas liquids train. The natural gas liquids will then be sent to GASCO Ruwais for further fractionation.
In alignment with ADNOC’s environmental policy, a new sulphur recovery unit will be installed to handle acid gas flows from train 4 and acid gas from trains 1, 2 or 3 and visa versa. This will also be managed by WorleyParsons.
