Following the handover of the Mtwara to Dar es Salaam Pipeline Project in August 2016, a project close-out ceremony was held in October 2016 in celebration of the tremendous success of the project, attended by Tanzanian Government officials, client Board Members, other project stakeholders, as well as members of the media in Tanzania. At the project inauguration WorleyParsons was acknowledged by the former President of Tanzania with a Certificate of Achievement “in recognition of their valuable contribution to the successful completion of the engineering, procurement, construction and commissioning of the two natural gas processing plants at Mnazi Bay and Songo Songo Island, a total of 551 km of transportation pipeline which include offshore pipeline from Songo Songo Island to Somanga and onshore pipeline from Mtwara (Mnazi Bay) to Dar Es Salaam (Tegeta), as the project management consultant (PMC), which has greatly benefited the United Republic of Tanzania”.
The global project delivery and engineering consultancy was also commended by the Tanzania Petroleum Development Corporation (TPDC) on achieving 275 000 safe hours worked. “The project expended over 14,9 million hours worked of which more than 10 million safe hours were worked, that included the PMC team’s achievement of 276 344 safe hours worked. The project total recordable frequency rate is 0.107 which is an excellent achievement and comparable globally,” says Allan Slowe, WorleyParsons’ Senior Project Manager for the Mtwara to Dar es Salaam Pipeline Project.
WorleyParsons was appointed as the PMC in 2012 by the main EPC contractor China Petroleum Technology Development Corporation (CPTDC) in a monitoring and advisory role for the Mtwara to Dar es Salaam Pipeline Project, including training and mentoring of client personnel. The project was implemented by a consortium of contractors to undertake basic engineering, followed by detailed engineering in China; procurement and inspection in China, South Africa and various other locations around the globe; fabrication and delivery to Tanzania of materials and equipment; site establishment at the gas processing plants and along the pipeline route for the storage and installation of the pipeline and associated facilities; construction, pre-commissioning and commissioning of the gas processing plants, onshore and offshore pipelines; and take-over and handover of the facilities.
The project facilities are designed for 350 mmscfd (million standard cubic feet per day) but capable of ultimately producing 1002 mmscfd.
Allan Slowe comments that the project implementation model that WorleyParsons used played a key role in the success of the project: “The PMC model ensured that a professional, positive and close working relationship was forged between the client, EPC contractor and other stakeholders that enabled us to effectively manage the various challenges that ultimately resulted in the successes on the project.
“In addition to the positive relationships forged and excellent safety milestones achieved, the project was completed within the $1,225Bn budget, and key date deadlines met. Furthermore, world-class quality was achieved on the project by implementing the PMC model. In particular, the weld repair rate for the onshore pipeline was 0.79 which is an excellent achievement and comparable globally,” says Allan Slowe.
The objective of the Mtwara to Dar es Salaam Pipeline Project is to ensure adequate and reliable power supply for the country and to provide affordable and reliable energy for industries. This forms part of the Tanzanian government’s goal to add over 2 000 MW of new gas-fired power plants by 2018 and a total 10 000 MW of generation capacity by 2025 up from the current 1 500 MW, and has formed the ‘backbone’ for the growth of the country that is included in the final draft of the Natural Gas Utilization Master Plan for Tanzania.
