Shell Shares How They Achieve Operational Excellence via High-fidelity Operator Training Simulators

The hydrocarbon processing industry struggles today with operating larger, more complex plants with fewer people responsible for even more tasks. Both control room and field operators require extensive DCS and plant training, regardless of their current experience or proficiency. Control room operators run mission critical processes across multi-billion dollar businesses where missteps can be very costly in terms of safety, availability, and profitability. It is for this reason that companies must find a way to attract and retain the next generation of engineers and operators by establishing long-term training strategies.

Operator training simulators are widely used across the process industries to meet both safety and performance objectives. The objectives of an OTS vary, but most are implemented for some variation of the following:
    Controls testing/commissioning time and risk reduction
     ─   A control checkout and logic testing tool to reduce commissioning time
     ─   Process analysis: scenarios, shutdowns, debottlenecking
     ─   Decision support tool to improve avail-ability and reliability
     ─   An engineering tool to lower capital and operating costs
    Knowledge management
     ─   Console & field operator training
     ─   Operator certification
     ─   Best practices capture and standardization
     ─   Knowledge transfer from experienced to new personnel

Training can cover both common and extreme scenarios in a risk-free environment, including, but is not limited to:
    Steady state operations
    Procedures for plant start-up and shutdown situations
    Handling of utility system and process unit trips, turndown and other upsets
    Fault diagnosis, alarm handling & corrective actions for equipment malfunction during normal operation

A well-defined operator training simulator considers all the necessary training elements including hands-on experience, direct feedback, evaluation and assessment of trainee progress. An OTS uses dynamic simulation technology to produce a high- fidelity representation of the processing system including the process equipment, controls, and automated procedures. The dynamic simulation calculates, in real-time, how the process system will respond to outside influences such as feed changes or operator control actions like unit stop/start or set point changes.
As operators and personnel switch jobs and/or migrate between various operations, technology holds the key to engaging the next generation of operators. The reduced training time an operator training simulator provides keeps skills current, operators qualified, and can accelerate careers by keeping trainees more engaged and invested with updated tools. As Earl Wallace from Shell Canada Scotford will show, these training strategies support the capture and transfer of best practices, thus increasing efficiency, driving safety initiatives, and maximizing profitability within the plant and across the enterprise.

Update to SimSci Licensing Options

Dear SimSci Software User, 

This post is to provide an update on the licensing and security options from Flexera Software, who produces the security software that SimSci software products use for LAN, WAN, and Token Licensing. Flexera Software FLExNetPublisher (FNP) 11.11 and (FNP) 11.12 have reached the end of limited Lifecycle support.

In an effort to support our customers going forward, SimSci is supporting now the latest version of FlexNetPublisher, 11.14.  The SimSci team is implementing the following plan:

1.       Existing FNP 11.11 and FNP 11.12 security licenses will be upgraded the next time they are renewed to FNP 11.13 or FNP 11.14. However, we do recommend that you upgrade at your earliest opportunity to avoid any potential problems.  
2.       Older FLEXlm licenses will continue to work, however, if they stop working before the renewal period, they must be upgraded to FNP 11.13 or FNP 11.14.
3.       Future installations of SimSci software will allow FNP 11.13, FNP 11.14 and respective TOKEN versions, and USB security options. 
4.       The latest server software install and a retrofit package to upgrade all your SimSci software to use FNP 11.14 can be downloaded from the Support Site.  
5.        Any customer migrating to Windows 10 will need to upgrade to FNP 11.13 or FNP 11.14 as previous versions of the server do not install in Windows 10. 

We appreciate your patience through the migration and will do our best to minimize the impact on your use of our products. Please contact technical support if there are any problems.

For Simulation Builders:

  • Faster and more reliable editing of curve data.
  • Improved the way Snapshot variables are saved in Snapshots to support upward compatibility.
  • There are now Torque and Acceleration variable types.
  • Mole fractions may be in ppm.

  • Typical Connection Models can be a stream for process simulation, or a pipe for fluid flow simulation.


  • Thermo Data Manager (TDM) integration, DETHERM PPDX support, Grayson-Streed correlation, Racket liquid density method, COSTALD liquid density method, Vapor-Liquid-Water (VLWE)

Control Library:

  • The PID controller now has mole flow and volume flow options.

Cooling Water Library:

  • There is now a Reducer / Enlarger model. The Pump now has a Net Positive Suction Head calculations for NPSHR (required) and NPSHA (available); calculate efficiency from the pump performance curve.

Flare Library:

  • The Pipe is the default Connection Model; PipeRig is optional The Pipe calculates density times velocity squared variable called rhov2, commonly used for flare pipe sizing. If the Pipe Service parameter is set to InletPipe, the pressure drop is calculated to check the 3% rule, but is not applied to the relief valve inlet per API 521 practice. PipeRig uses equal length segmentation as a more reliable default setting, especially for low or zero flow and includes no-slip holdup in each segment.
  • The Stack calculates Thermal Dosing Units (TDU) from Health and Safety Laboratory (HSL) report “Human Vulnerability to Thermal Radiation Offshore”.
  • There is a FlowPort to FlarePort converter to create simulations consisting of both Process and FlareLib library models.

Steam Library:

From China overtakes US as top crude importer as refinery maintenance slows

China’s crude processing is poised to climb 2.5% in the next three months from the previous quarter amid reduced refinery maintenance, according to industry analyst forecasts.


China regained its status from the US as the world’s biggest crude oil importer as shipments surged to fill the Asian country’s strategic petroleum reserves.

Overseas purchases by China rose to 29.49 million metric tons in June, a 27% increase from May when shipments were the least since February 2014, according to preliminary data released by the Beijing-based General Administration of Customs on Monday. That’s equivalent to about 7.2 million bpd, Bloomberg calculations show. US crude imports last month averaged 7.08 million bpd, according to data from the Energy Information Administration.

China’s crude imports rose as it began filling the second phase of emergency reserves in the eastern city of Qingdao that have a capacity of 3 million cubic meters (about 19 million bbl). Oil imports may climb in the third quarter from the previous three months as another storage site in the southern Chinese city of Huizhou is scheduled to open, according to ICIS China, a Shanghai-based commodity researcher.

“Filling of the strategic reserves in Qingdao definitely played a part in the increase,” said Amy Sun, an analyst with ICIS China. “China will overtake the US as a permanent top crude importer in a year or two.” Read more here

How to Remain Profitable in a Tough Oil Market

Given the recent drop in oil prices, companies are presented with a dichotomy—while they’ve cut 2015 capital expenditures (CAPEX) by 25-40%, production levels for existing operations are likely to remain at 2014 levels, or higher. The challenge now lies in improving operational efficiency and productivity, reducing costs, and mitigating risk to remain profitable in this tough oil market. This paper presents a single real-time performance-based solution for simulating, operating, and optimizing your upstream operations. Learn more here.
