Turnarounds

turnaroundTurnaround project planning and scheduling can have a significant impact on maintenance costs and bottom line plant profitability. The Equity Engineering Group (E2G) can help you maximize up time, minimize downtime and achieve the most efficient use of equipment. Our goal is your goal: a strategically planned, “No Surprises” turnaround operation.

Risk-Based Inspection (RBI), Fitness-For-Service (FFS) and remaining life assessment can all save time and minimize risk both before and during the turnaround (TAR) cycle.

Planning TAR

  • RBI helps plan and optimize the amount of equipment needing inspection.
  • RBI enables on-stream inspection opportunities to prepare for TARs, minimizing costs by shortening TAR length
  • If on-stream damage is found and measured, FFS can be used to see if repairs or replacements are necessary.
  • Remaining life studies of critical equipment, like reformer heaters, can determine if re-tubing is necessary; and for other equipment, these assessment show whether replacement or repairs are necessary – for example, equipment in High Temperature Hydrogen Attack service.
  • FFS modeling on high temperature equipment, often with Finite Element Analysis (FEA) can be used to optimize cool down with depressurization of equipment to minimize damage and brittle fracture potential; it can also be used with the heat up.
  • For critical equipment, such as heavy wall reactors, proactive FFS defines the most critical areas of inspection and maximizes tolerable flaw sizes for the upcoming run time; this dictates NDE types and sensitivities required to find flaws or damage.

Prior to TAR

  • E2G subject matter experts can assist during the formal workscope review by challenging the workscope list.
  • With our hands-on mechanical, metallurgical and materials engineering experience plus knowledge of industry best practices, codes, standards and regulations, we can help you refine and perhaps trim the list.

During TAR

  • E2G can provide an on-site support coordinator for facilitating and performing any services required during the TAR.
