TURN-key
Coordination between control and field instrument, drive is a big challenge in an automation project. Generally, multiple suppliers and vendors with different quality level get involve in an automation project because not only the budget and quality of field devices and their conformity with the customer requirement but also vendor’s local support and local inventory affect on vendor selection.

In a control system modernization project, amount of risk for returning to last production in preschedule time, necessity for plant downtime and budget of migration plan against advantage can be gained by new control system conduct customers to choose between these modernizations scenarios: 1-HMI 2-Controller and HMI 3-Complete change Read MoreDCS MIGRATION BY HOT CUTOVER
Zero plant down time is an aim of any DCS migration plan. Depends on type of changes that are considered in a DCS modernization plan there are multiple solution and method in the market. A hot cutover is a solution for moving loops to new control system in online process condition. Utilizing hot cutover plan and tools can prevent plant downtime during migration process. Read MoreCONTROL SYSTEM UPGRADE BY ZERO PLANT DOWNTIME
The new modern control system advantages in improving production throughput and increasing plant safety against high maintenance cost of legacy control system may direct customers to a complete replacement plan, but replacing whole the control system by a new one aside from higher cost is not always the best solution to gain those advantages and dissolve the maintenance issues. Read MoreCHANGE VENDOR TECHNOLOGY IN A DCS MIGRATION
When cost of maintaining legacy control system and risks of plant downtime increased, desire for resolving old DCS issues and gain advantage of modern control system put the customer at two-way selection; migrate to a new DCS by staying on vendor technology or change the technology. Read MoreADD VALUES TO OLD GAS TURBO MACHINES BY RETROFIT
The high budget of gas turbo generators is an obstacle for investing on them at industries with large amount of electricity consumption that desire to have in-house steady low cost source of power. Investment in used robust gas turbo machines is a cost effective solution for those factories that wants to have their own in-house power station. Read More
TURN KEY REVAMPING
7209 was a retrofit project in a gas condensate separation plant in upstream of a large petrochemical factory with million dollar revenue in a month. Any shutdown cost for customer a lot but inefficient operating among system failures increasing, part unavailability, and reduced support caused frequently plant downtime and risk of safety incident and loss revenue directed the customer to a retrofit solution.

UPGRADE TO ABB 800xA
Project 7129 was about upgrading DCS, ESD (Emergency shutdown) and F&G (Fire and Gas detection System) of an oil offshore platform with zero plant downtime. Existing control system in the platform includes, three Redundant Set of ABB Advant AC450 in DCS and two sets of Dual Safegaurd in ESD and F&G system and five ADVA command operator consoles.

STEAM TURBINE GOVERNING
As part of a big petrochemical revamping project we retrofitted control system of steam turbines from Ellliot-Ebara at heart of a process plant. Additional to high cost of maintenance and insufficient operation, the old hydraulic governor system of steam turbine was raising problems during operation and caused many unexpected plant shutdown.
