UK supermajor BP has made initial approaches to fabricators about the next big platform it needs for its giant Azeri-Chirag-Guneshli (ACG) oilfield development off Azerbaijan, with the overall development thought to be valued upwards of $3.5 billion.

At least three industry sources told Upstream that BP recently initiated a pre-qualification exercise for another huge production platform, to be known as Azeri Central East (ACE), and other associated offshore facilities required for the development project.
