Bintuni Bay is a delicate ecosystem, with many challenges. BP recognizes its responsibility to minimize the environmental impacts of our operations in the Bay area and to actively support biodiversity conservation measures
Compared to other resource extraction projects, the direct physical impact of developing the Tangguh natural gas fields is relatively small. Nevertheless, it is still important to minimize any negative environmental consequences of our operations. An Environmental Impact Assessment (EIA) has been completed to help us identify and mitigate negative environmental impacts during the construction and operational phases of the Project.
The land acquired for the LNG plant covers 3,200 hectares – most of which will remain a ‘green zone’. Processing facilities are being designed with energy efficiency as a key performance measure, with the decision taken to recover heat from the plant’s gas turbine exhaust. Tangguh will be the first green-field LNG start up project to incorporate this energy-conserving feature.
Drilling fluids and cuttings
Drilling fluids and cuttings can have a negative environmental impact if they’re not disposed of in an appropriate way. The most environmentally-friendly way of dealing with them is to re-inject all drilling fluids and cuttings into underground formations – and to set zero discharge targets for all drilling and completion activities. Re-injection remains our first option for the Tangguh Project, but if it proves technically infeasible, other disposal methods, such as onshore landfill, will be considered if they comply strictly with Indonesian and World Bank environmental standards. Only in emergency situations will drilling fluids and cuttings ever be discharged into Bintuni Bay.
Greenhouse gas emissions
The natural gas in the Tangguh fields contains approximately 10% CO2 - relatively high by industry standards. We have commissioned studies to identify options for reducing greenhouse gas emissions from the plant, including the possibility of capturing and storing CO2 from the LNG feed stream, and are working with other BP LNG projects in Australia and Trinidad to share new ideas and best practice. The Project team has also collaborated with vendors of proprietary LNG designs to identify energy efficiencies, which, if implemented, could produce significant reductions in greenhouse gas emissions compared to standard industry levels.
A catalyst for conservation
Over and above our efforts to mitigate the environmental risks of our operations, we also want to be a catalyst for improved conservation efforts locally, regionally and nationally. Bintuni Bay supports southeast Asia’s most extensive intact mangrove area, located 80km east of the Tangguh site. When construction of the LNG plant starts, the Bintuni Bay Nature Reserve will become the focus for our flagship Biodiversity Action Plan (BAP). The aim of the BAP is clear: to support conservation in a direct way, which delivers measurable positive net benefits to local biodiversity.
