The operator may be the End User himself or a JV with multiple End Users being involved. Because of the level of detail requested for the execution this phase may also be called “Detailed design”.
Comments: During the “EPC” phase, the engineering companies may work with different types of contract, but always under a close follow up of the End User. In practice it means that the nominated “EPC”. By extension “EPC” is used for the engineering companies executing “EPC” contracts. Note that all the engineering companies are not necessary “EPC” as some of them focus on the “FEED” or multiple services but the “EPC” contracts as they require different expertise and financial dimension.
