Hook-up and Commissioning activities are part of "Brownfield" and "Greenfield" Construction to be executed either in Onshore or at Offshore.
The term "Brownfield" construction refers to revamping works on existing facilities to enhance production which involve repairs, upgrades, replacement and modification works on existing offshore production facilities and Equipment. Brownfield Construction are generally undertaken when Operators recognize the need to improve Safety aspects, Production, Efficiency and Lifespan of their existing facilities as well as to address maintenance and regulatory compliance issues and update technology. As a whole Brownfield Construction is a combination and synchronization of new components to the existing facilities and it is essential to understand and appreciate how they are inter-related from physical, process, Hook-up and Commissioning and Operating perspectives. It also involves tie-ins to existing facilities for which disruption to ongoing production cannot be avoided and eventually may lead to shut-down of the existing facility for a certain period of time.
The" Greenfield" construction term refers to a new facility either a Wellhead or Process Platform which has been constructed from scratch at NPCC yard and eventually loaded via a cargo barge for further installation offshore. Unlike "Brownfield Construction, hook-up and commissioning activities related to "Greenfield" construction has no restriction at all in terms of permit to work system application may it be "Hot or Cold" works considering that the facility is yet to be handed over to the client upon mechanical and commissioning completion.
