We want to help manage areas in which we work – to minimize any adverse impacts our?activities have and find opportunities to make a?positive contribution to environmental protection.
Work in ways that result in no accidents, no harm to people, and no damage to the environment, including no net loss to biodiversity when undertaking new projects in sensitive areas.
We work hard to understand any environmental and social sensitivities in the areas where we operate. With this understanding we:
A marine mammal and sea turtle baseline monitoring and data collection programme was initiated off S?o Tomé and Príncipe in 2018 and has continued throughout 2019. The programme aims to help improve knowledge and understanding of the presence and movement of marine mammals and sea turtles around S?o Tomé. This includes an acoustic marine mammal and soundscape study using a combination of fixed passive acoustic recorders and an autonomous surface vehicle to collect data over a wide area.
We’re also supporting the local NGO Programa Tat? to monitor sea turtle nesting and tagging turtles to see where they are going during and after nesting.
The data from these surveys is not only helping to understand the ecology of these species, but also helps inform our planned activities and avoid the most sensitive areas and times of the year.
One of the major demands for freshwater is for cooling in our refining and petrochemical operations. Balancing the corrosion, scaling and microbiological risks of the cooling water while minimizing the volume of freshwater required for optimum cooling performance is a routine challenge at these operations.
At Texas City Chemicals, located in an area of medium to high water stress, we undertook a detailed monitoring and modelling study to improve cooling water quality and reduce freshwater demands to optimize the cooling tower operation. This involved a collaborative approach from bp and our suppliers to test different cooling cycles (the number of times cooling water can safely be recycled before being replenished with fresh water) and different chemical treatments to optimize the water chemistry.
Through modelling and monitoring we have been able to lower the demand for fresh water by over 270,000m3 per year. We will continue to reduce the fresh water requirement by optimizing cooling tower operations and reducing chemicals usage.
We’ve assessed historical and future precipitation related flood risks during the planning for a new project at our bp Rotterdam refinery. The new project will result in additional paved areas and capacity for increased storm water volume to be managed. Based on the results of our assessment, the need to expand storm water pumping capacity was highlighted.
Storm surge risk was also looked at as part of the assessment, taking into account both existing flood protection measures and up to date storm surge scenarios. High resolution maps of flooding from storm surge and precipitation for a variety of climate scenarios were developed.
The new data on precipitation and storm surge flood risks has been incorporated into the site’s major accident hazard report for future reference.?
