Engineering IT Solutions

Wako trust Ltd. is always looking to strive for excellence by keeping in-line with the recent trends in engineering and design. The share market of SmartPlant Instrumentation has risen sharply in the recent years. More and more companies are using this software solution package to enhance their work efficiency as well as improve the quality of their design work. For this reason Wako Trust Ltd. has recently enhanced its capability in terms of incorporating SPI into its engineering design work. We have a team of highly capable individuals that are well-versed with the dynamics of working with engineering tools such as SmartPlant Instrumentation. It brings us immense pleasure to inform our clients that we are now capable of handling any job that employs SmartPlant Instrumentation as a design engineering tool. From SPI database setup for FEED, to incorporating As-built information, our engineering and IT support team covers all bases of design engineering using SmartPlant Instrumentation.


SmartPlant Instrumentation Administration Services

Successful execution of a project that employs SPI is heavily dependent on the role of the Smartplant Instrumentation Administrator. This individual is the one who will be an inherent part of the project from early ‘SPI database setup’ phase to ‘database hand-over to client’ phase. A brief point-wise explanation of the duties performed by the Smartplant Instrumentation Administrator are as follows:


  • Database administration, creation and management tasks – Creation & setup of Smartplant Instrumentation database along with periodic maintenance and back-up. This includes database migration and re-initialization, if the need arises.


  • System & Domain Administration tasks – Initializing project domains and setting up the initial project conventions and standards as agreed by the client. This includes all reference data that will be used by the engineers for the rest of the project. Setting up and controlling user access to SPI throughout the course of the project, is also part of the Administrator’s job.


  • Troubleshooting & IT support – Provide constant support to engineers working on SmartPlant Instrumentation. Create documentation and procedures to help them in this cause. Troubleshoot problems encountered by these users during the course of the project. Coordinate with Intergraph support for problems that are beyond the control of the Admin.


  • Integration tasks – Successfully integrate SPI with various other Intergraph tools in the SmartPlant Suite. Integrate SPI with various vendor data interfaces supported by SmartPlant Instrumentation.


  • Miscellaneous activities – Take care of licensing. Handle and use all SPI supportive software such as Infomaker, SmartSketch, MS Access, Enhanced Smart Loop etc. Use SQL queries to carry out database tasks, time-effectively. Work on custom reports & deliverable documents requested by engineers & client.

Using SmartPlant Instrumentation as a design engineering tool

Our Instrumentation and control engineers are fully capable of executing all engineering and design work using Smartplant Instrumentation. They have the necessary skills and expertise to use SPI to their advantage and get the most out of this software package. Project deliverables such as Inst. Loop drawing, Specification datasheets, Hook-up installation drawings etc. can are generated via SPI, thus unleashing SPI’s full capability, including the automated generation of project deliverables.


SmartPlant Instrumentation – Application hosting services

At Wako Trust Ltd, our next target is to step into the business of application and infrastructure hosting, starting with SmartPlant Instrumentation. We are currently working on this idea, gathering all necessary resources to execute it successfully. Once executed, we would be able to host Citrix server along with SPI server at our company location. Henceforth, remote engineering offices can connect to SPI using a secure internet connection with minimal IT infrastructure requirement. In this scenario we shall take care of three major roles related to application hosting:

  1. Citrix Server Administration

  2. Project Database Administration

  3. SmartPlant Instrumentation Administration

Such a scenario would be ideal for projects that include multiple contractors/subcontractors working in their own respective domains for a single engineering project. Such a work-share strategy can be employed successfully using the Citrix server. The engineers can then connect to the central project database using a Citrix interface. This work dynamic would ensure unification of data in a single SPI project database that is managed and maintained at our locality.
