Client Testimonials

Trusted by Industry Leaders

VesselKart migrated our obsolete Siemens S5 rack to an S7-1500 system. Their clean tag naming and dynamic diagnostic screens on the HMI made a massive difference. Now our operators can trace a faulty solenoid valve in seconds, not hours. Efficiency has climbed significantly.

We had a strict, tight window to commission our new bottling line on a CompactLogix CPU. VesselKart wrote the logic off-site and completed full FAT testing in their lab first. They finished loop-checks 3 days early with zero bugs during dynamic start-up.

A critical CPU faulted on a Saturday night and halted our entire spinning line. VesselKart's emergency engineer dispatched to our plant immediately, diagnosed the rack fault on-site, and had us running again in under 2 hours. Outstanding response time.

Their overhaul of our vessel's ballast control PLC was seamless. They refactored the legacy Siemens code into modular, reusable blocks, and clean diagnostic screens on the HMI made alarm tracing foolproof. Our crew can now troubleshoot on the water with ease.

We hired them to design a multi-node SCADA system for our tank farm. The interface is intuitive, following high-performance grayscale standards to reduce operator fatigue. Alarm shelving features have completely solved our historical issues with alarm storms.

Their Studio 5000 programming for our packaging lines is clean and exceptionally structured. VesselKart's use of Add-On Instructions (AOIs) and detailed comments made it very simple for our internal electrical team to perform maintenance later.

Excellent execution on our Omron Sysmac platform upgrade for the assembly conveyor. The motion control synchronization via EtherCAT was setup perfectly. The cycle time decreased by 12% and the servo positioning is rock solid.

VesselKart provided stellar support during our hot-cutover migration. Their structured programming logic and systematic loop checking saved us hours of potential downtime. They are a reliable team of automation professionals.

Our brewing process requires very precise temperature PID loop tuning. The controls team at VesselKart tuned our loops to eliminate temperature overshoot completely, preserving the flavor profile. The HMI trend screens they built are fantastic.

Replacing our redundant Modicon Quantum PLC with the newer M580 platform was a high-risk project due to furnace operations. VesselKart completed the swap-over and hot-standby configuration without a single hiccup. Highly recommended.

Their design for our plant-wide Ignition SCADA system included full server redundancy and database replication. The failover testing was thorough, and their clean layout designs have made process monitoring incredibly straightforward.

VesselKart redesigned our vessel's boiler control system logic on an Allen-Bradley platform. Their attention to marine safety interlocks and marine class society rules was impressive. The system passed the sea trials on the first run.

The team designed an exceptional SCADA interface for our desalination station. By applying high-performance HMI concepts, they minimized visual clutter. Operators now spot out-of-spec pressures immediately, boosting safety.

We had a recurring communication issue between our paper machine PLC and the main DCS. VesselKart diagnosed a Profibus network bottleneck, corrected the termination, and optimized the PLC polling rates. Stable operation restored.

Their clean code structure for our heavy-duty iron ore crushers has worked beautifully. The interlock logic is extremely robust, protecting our equipment from operator errors. Their documentation was exceptionally thorough.

For our pharmaceutical validation process, we needed detailed documentation. VesselKart delivered clean, commented Siemens code, complete with detailed software design specifications that made our FDA GAMP5 compliance audit run smoothly.

Their Beckhoff TwinCAT 3 Structured Text programming for our high-speed lithium battery assembly lines was flawless. They handled multiple EtherCAT axes with microsecond precision. A very capable engineering team.

Our old Siemens PLC was maxed out on memory and constantly slowing down. VesselKart optimized our data blocks and structured logic to clean up memory, then upgraded the hardware. The scan time dropped from 85ms to 12ms.

We had outdated touchscreen HMIs that operators struggled to read. VesselKart redesigned the screens using clear, high-contrast layouts and responsive touch areas. Operator input errors have dropped to virtually zero.

Integrating our turbine monitoring sensors over Modbus TCP into the central SCADA was a major headache. VesselKart's engineers mapped the register maps, resolved byte-swapping issues, and created clear diagnostics. Very professional.

The packaging machinery logic VesselKart developed using Schneider Machine Expert is highly structured and well-commented. Their use of custom function blocks made troubleshooting limit switches and photoelectric eyes extremely easy.

VesselKart's preventive maintenance and AMC service has been invaluable. They mapped out all our regional stations, performed thorough on-site panel audits, and standardized the PLC software versions for clean local troubleshooting.
