The TAIL IO Project Improves Operations
Figure 1: Screenshot from the Turnaround and Shutdown Application
The goal of this project is to develop a tool that can accommodate a
vast and complex range of data with the ultimate objective of
minimising the number and length of asset shutdowns. The work
processes, methods and solutions developed will consist of three main
building blocks: a turnaround and shutdown knowledge analyser, a
turnaround and shutdown risk analyser and a turnaround and
shutdown optimiser. Development of the knowledge analyser and the
risk analyser is well on its way. These solutions will be the basis for
developing the optimiser. The first prototypes are ready, and pilots
have been started. Three offshore facilities are currently using the
prototypes for monitoring the performance of their 2008 turnarounds.
A first prototype of a solution for simulation and optimisation of
turnarounds has also been developed (see Figure 1). It will be tested
on one facility this year, with further development planned.
Wireless Communication and Sensor Systems
IO requires reliable and smart instrumentation. On existing offshore
facilities, there is little or no space available in cable trays for
additional cabling, and the cost of adding new hardwired
