Modernization work progresses on Indonesian frigate KRI Usman Harun
Dutch maritime technology provider Nevesbu, working closely with prime contractor PT LEN Industri, carried out the platform systems integration engineering on the Indonesian Navy’s light multipurpose frigate KRI Usman Harun.
The company has informed that, to enable the conversion, demolition work to remove the existing mission systems and constructions from the ship is currently underway.
The company will also provide site support during the conversion.
As a platform systems integrator, Nevesbu is responsible for all engineering necessary to integrate mission systems into the frigate while ensuring that the system and all onboard subsystems operate as intended.
This includes defining demolition works and designing modifications to the vessel structure, platform utility systems, foundations, cable routings and room layouts in accordance with specified requirements.
Before the design work, Nevesbu maps the current situation by carrying out inspections on board the vessel. The firm details the existing situation aboard the KRI Usman Harun using 3D laser scanning.
3D laser scanning data collection provides an accurate overview of the vessel’s layout and the exact location of all systems, cables and pipes. This information is essential to properly adapt all new equipment to the existing environment, according to Nevesbu.
“Foundations often have to be adapted and new mission systems also require changes in auxiliary systems, cables, pipes, etc. Wiring should not be susceptible to interference and should be spaced far enough apart to avoid interference. At the same time, the operational arrangement must be as efficient as possible and the energy balance and stability of the vessel must be monitored”, noted Nevesbu.
The company also noted that warships must meet strict requirements for stiffness when firing ammunition, impact resistance in the event of an explosion, and overall structural strength.
For this reason, during the development of the design, the company constantly seeks an ideal balance between strict requirements and optimum efficiency for the crew in terms of operability and maintainability.
