International Perspectives on Environmental Assessment, Engineering, and Planning

Environmental assessment, engineering studies and designs were completed for a new 26.5 m3/s seawater intake system in the Persian Gulf. The original intake facility consisted of a curved, 60m breakwater with one end attached to the shoreline, a settling basin immediately adjacent to the shoreline and dredged to a maximum depth of approximately 5m, and a pumphouse structure located on shore such that the seaward wall formed one side of the settling basin. The facility located on an island in the Gulf, which served multiple seawater uses, had experienced both structural and operational problems, the latter consisting principally of excessive ingestion of sediment and seaweed. These factors plus the requirement for additional demands for seawater beyond plant capacity caused the owner to initiate a study of alternative intake systems, produce a design for the most effective solution and construct the new intake system.

The Preliminary Environmental Assessment (PEA) at Petrobras consists, in general terms, of an internal technical process, prior to environmental permitting, to verify the environmental feasibility of a project and identify the main environmental issues. It will also add to the future Environmental Impact Assessment Study (EIA). The technical guidelines for the PEA are prepared by the multidisciplinary team at the Petrobras Environmental Assessment Engineering Group (EAMB) of ENGENHARIA/IETEG/ETEG and are based on the characteristics of the project. The PEA is one of the elements of the environmental impact assessment, providing an initial assessment of the environmental aspects of the project (Screening). It also supports the assessment and determination of route and location alternatives of pipelines and industrial plants. The UTGCA (Caraguatatuba Gas Treatment Unit) will process gas and condensate from the Mexilha˜o Field, on Santos Basin – SP. This paper presents the procedures and conclusions of the PEA prepared for the UTGCA project by PETROBRAS/ENGENHARIA/IETEG/ETEG/EAMB.
