Bayu Undan Detailed Design

The Bayu Undan surface facilities consist of  three primary components: a central production and processing (CPP) complex; an unmanned well head plateform; and a floating storage & off loading facility (FSO). The Central Production and Processing complex - comprises two separate platforms linked to each other by a bridge. The platforms are the Drilling, Production and Processing (DPP) platform and the compression, Utilities and Quarters (CUQ) platform. The combined topsides facilities weigh close to 26,000 metric tons, and they sit on top of two eight pile steel jackets.

 The DPP platform provides approximately two thirds of the 1.1 billion standard cubic feet per day of raw liquid rich gas from the reservoir via four production wells. It also provides the processing facilities to separate the well fluids into gas and liquid products.

The CUQ platform Provides the compression facilities for the processed gas to be either reinjected back into the Bayu Undan reservoir or exported to shore via a subsea pipeline. It also contains living quarters for eighty people and a helideck.

The FSO is equipped with refrigeration, liquefaction, gasification facilities and can store 130,000 cubic metres of condensated and 95,000 cubic meters combined of propane and butane. Condensate offloading is conducted in a tandem shuttle tanker bow to FSO stern configutation, whilst LPG offloading is carried out in side by side configuration.

Following the incidents of PiperAlpha risk management was foreseen by the Bayu Undan project development team as a key requirement in the develipment of the design of Bayu Undan. A Process Safety Management program relies on accurate information about the equipment beign used throughout the process. Deficiencies in Piping and Instrumentation Diagrams (PIDs) can lead to errors in operating procedures and possible human injury. Kirsty was one of the Risk Management Specialists responsible for the risk assessing  PIDs for process, human error, enviromental and safety risks. Risk assessments were undertaken in teams and individually allow all specialiest to review potential risks from all angles including multiple failures.
