Dredging
ATS has completed several projects with dredgers and successfully completed sea trials. Control of the suction and blowing arms, the pumps, engines, motors, dumping hatches etc. is achieved with on-board PLC’s.
Modern dredgers use GPS (Global Positioning Systems) to define their position and PLC and SCADA systems are used to control these powerful vessels.
In some cases PLC’s are installed in the suction and blowing arms which operate under sea level to improve communication speed and response. SCADA is used to supervise the whole process and provide operator interfaces, data collection and detailed information on material moved and placed. Fieldbus networks using conventional cable and fibre-optic cable provide on-board communication. Due to the harsh environments in which the dredgers operate all systems are redundant and failure of individual units on the ship will not cause system wide failure.

ATS has been involved in hundreds of projects for the steel industry over many years. Control applications using a wide variety of PLC and SCADA systems for ovens, rolling mills, transport systems, cranes and peripheral activities such as water treatment and cooling have been implemented in many plants in different countries.

After a major renovation of this plant the maintenance engineers were having problems with the new technology that had been introduced. ATS prepared a special training that included specially developed example programs to help the maintenance engineers use the PLC programming software to identify problems and finding solutions. The ATS Lecturer even developed some model hardware allowing the trainees to practice the effects of their programming, a very visual way of seeing the results of their efforts.

A complete installation was built and installed by a large German supplier and was installed in the Netherlands. After installation the operators requested changes in the SCADA application. ATS engineers were invited to discuss these requirements directly with the operators themselves and then implement changes to the software on-site. After completing the changes ATS arranged a tailor-made
training for the operators and maintenance staff after fully documenting the application.

Wonderware InTrack was introduced to the company in order to provide information (order status, work instructions, machine failures, availability of machines & tools & instruments) to the production department as well as information about efficiency and quality assurance to the other parts of the company.
