Pemba Oil & Gas

Pemba Bay, a natural bay on Mozambique’s north coast, was the perfect site for a new oil and gas service centre.

Mozambique's national oil company, Empresa Nacional de Hidrocarbonetos (ENH), joined forces with the Mozambique Ports and Railways (Portos e Caminhos de Ferro de Moçambique – CFM) to form Sociedade Portos de Cabo Delgado (PCD), an entity that will be able to provide offshore oil and gas support facilities in Mozambique’s Cabo Delgado province. Pemba, the capital of the province, was identified as the best location for a new logistics support base in the north of Mozambique. PCD granted ENH and Sonangol Integrated Logistics Services a long-term concession to deliver and operate offshore support services there. This new oil and gas service centre is an essential component in developing hydrocarbon fields off the northern Mozambique coastline.

WSP in the UK first developed the masterplan for this facility in 2013 while the South African WSP team was commissioned to provide specialist marine expertise to front-end engineering design (FEED), procurement support and construction supervision and undertake the coastal and environmental impact assessments (EIA) of the area for the development of the first phase of the Pemba Oil and Gas Service Centre. The clients needed an EIA to understand the coastal hydrodynamic behaviour inside Pemba Bay and how reclamation activity would change the bay’s geometry, and affect circulation patterns and velocity vectors, as these could impact negatively upon existing mangroves, fish spawning and coral reefs. The EIA would also describe future-phase developments, including 5.5km of quay walls and inland commercial, residential and industrial zones at a conceptual level.

The challenges with this project were the tight deadlines. The environmental authorisation, in terms of the National Management Act, had to be obtained before starting contstruction, and, as the first gas must be delivered by 2018, the procurement and delivery of the first phase had to be fast-tracked.

Our solutions

Compressing the programme enabled early engagement of a contractor and engineer – on a design and construct basis – which meant the project stayed on track and met the deadlines.

The project also received environmental authorisation in December 2014, and provides WSP good exposure to the emerging oil and gas sector in Mozambique, as well as an opportunity to develop our relationship with our Mozambique partner, Impacto
