Our team recently completed a significant upgrade on the vessel’s KANGRIM Inert Gas Generator system, replacing and commissioning two new HMI panels on the local control panel and an additional HMI in the CCR. The new interfaces restored full functionality, improved system visibility, and enhanced operator interaction with one of the vessel’s most critical safety systems. This upgrade ensures smoother operation, clearer process monitoring, and improved reliability during cargo operations.

In parallel with the upgrade, the system underwent its Annual Health Check Inspection — a comprehensive evaluation designed to verify the condition and performance of all essential components. The inspection included verification of the oxygen analyzer and calibration accuracy, checks on control valve positioners, pressure and temperature transmitters, alarm and shutdown functions, communication signals, and overall system responsiveness. Each subsystem was assessed to confirm that it operated within specification and maintained proper integration with the IGG control logic.

During a recent onboard attendance, our team carried out a full operational check and performance verification of the vessel’s KANGRIM Inert Gas Generator (IGG). The inspection focused on ensuring that the system met all safety and operational requirements, with particular attention to combustion performance, oxygen control, and the correct functioning of all protective interlocks. Each subsystem was evaluated to confirm stable operation under normal working conditions.

The scope of work included verification of the start‑up sequence, assessment of flame stability, and continuous monitoring of oxygen (O₂) levels at the inert gas outlet. Functional testing of the control system and analyzer feedback loops was performed to ensure accurate response to pressure, temperature, and flow conditions. Additional checks were conducted on the scrubber and associated equipment to confirm proper operation and overall system integrity.

Our team recently completed a full health‑check inspection on a Kangrim Boiler and Oilon Burner as part of the vessel’s planned maintenance program. The inspection covered all major mechanical, electrical, and combustion‑related subsystems to ensure safe, stable, and efficient boiler operation. The boiler and burner were evaluated in detail to confirm that all components were functioning within operational standards.

The scope of work included visual inspection of the boiler, cleaning and inspection of the burner assembly, internal checks of the boiler control panel, and verification of the fuel system — including pressure, filters, and valves. The ignition system and flame sensors were tested, followed by a full burner sequence test covering pre‑purge, ignition, flame detection, and normal firing operation. Additional checks were performed on the combustion air fan, air damper calibration, safety valves, and all interlocks to ensure correct and safe response under all conditions.

We recently completed a comprehensive inspection of the vessel’s Kangrim composite boiler, performing detailed checks in both manual and automatic operating modes. The goal was to verify the boiler’s reliability, operational stability, and full compliance with safety standards. Our team examined all major components — including the burner, servomotor, pressure switches, solenoid valves, and auxiliary systems — confirming that each part operated correctly and consistently.

During the manual‑mode inspection, we verified the full start‑up and shutdown sequence, ignition performance, and proper response of the oil‑servo load adjustment. These checks ensured that manual control remains stable and predictable under all operating conditions. The system was then switched to automatic mode, where we validated correct modulation based on water level, pressure, and temperature inputs. The boiler’s control logic demonstrated smooth transitions between minimum and maximum load, confirming proper automation behavior.

Our specialized technical team recently completed a full restoration of a Kangrim Composite/Aux Boiler that had been found in a severely compromised operational condition. Upon inspection, the system presented multiple unsafe modifications, faulty wiring, and several failed components, all of which rendered the boiler inoperative and posed significant safety concerns for onboard operations. Restoring such a critical system required a structured, methodical approach and deep familiarity with Kangrim boiler architecture.

The overhaul began with the replacement of all damaged control components within the main panel, as well as the external field devices that were no longer functioning correctly. A new SDC36 controller was installed and configured to re‑establish stable steam pressure control, ensuring that the boiler could once again regulate its operating parameters with accuracy. In parallel, the flame scanners (Siemens LFS1.11A2) and their detection relays were replaced to restore reliable ignition monitoring and safety interlocking — essential elements for safe burner operation.

Our technicians proceeded with a complete service of the burner system, including inspection and cleaning of the oil gun assembly, verification of solenoid valve operation, and restoration of proper fuel and air delivery. Each subsystem was tested individually before integrating the components back into the full boiler sequence. This step‑by‑step approach ensured that every part of the system responded correctly and safely before moving to full operational testing.

Every inspection is more than a routine check — it is a commitment to safety, reliability, and uninterrupted vessel operations. During our recent attendance onboard, our technical team carried out a complete inspection of the Kangrim Inert Gas Generator (IGG), ensuring that all critical components were functioning correctly and that the system remained fully compliant with operational and safety standards.

The process included a detailed evaluation of mechanical and control elements, verification of safe operating parameters, and the application of preventive measures to avoid future malfunctions. Each stage of the inspection was performed with precision, methodical testing, and the deep expertise required for such a vital piece of onboard safety equipment. Through careful assessment and functional checks, we ensured that the IGG system responded correctly under all expected operating conditions.

The KANGRIM Composite/Aux. Boiler Restoration project involved a full technical recovery of a system that had been left in severely compromised condition. During our inspection, we identified multiple unsafe modifications, faulty wiring, and several failed components that rendered the boiler inoperative. Our team approached the task with a complete overhaul mindset, ensuring every issue—electrical, mechanical, and control‑related—was addressed methodically and in line with manufacturer standards.

As part of the restoration, we replaced all damaged control components within the main panel as well as the external units, installed and configured a new SDC36 controller for stable steam‑pressure regulation, and renewed the flame scanners (Siemens LFS1.11A2) along with their detection relays to ensure reliable ignition and safety. The burner system received a full service, including solenoid valves and the oil‑gun assembly, followed by extensive manual and automatic operational testing. These tests confirmed smooth combustion, correct sequencing, and safe boiler behavior under all operating modes.

The Inert Gas Generator (IGG) Inspection was carried out with a focus on ensuring safe, reliable, and efficient operation of the Kangrim system. Our technical team performed a full assessment of all critical components, checking mechanical parts, control functions, safety interlocks, and operational parameters. Each stage of the inspection was handled with precision, ensuring that the IGG met the manufacturer’s standards and operated within the correct safety limits.

Beyond the routine checks, preventive measures were applied to maintain long‑term stability and reduce the likelihood of future faults. The system’s performance was verified under normal operating conditions, confirming that all functions responded correctly and consistently. The result was a fully validated and dependable IGG, ready to support the vessel’s operations with confidence.
