BPA Begins Technology Development
for Port Crane Wire Rope Continuous Monitoring
Busan Port Authority (BPA), led by CEO Kang Joon-suk, announced on January 18 that it has initiated a project to develop technology for the "Port Crane Wire Rope Continuous Monitoring System."
Wire ropes are integral components of port cranes q-and demq-and meticulous management, especially considering the round-the-clock container loading operations at ports. For a typical container terminal crane, the average service life of the wire rope is around 3,000 hours. However, with the recent implementation of unmanned automation technology in the New Port West Container Terminal (Phase 2-5), the service life is anticipated to decrease to 1,800 hours or less due to extended operating hours.
While the terminal operator has been conducting regular inspections by assigning mechanics to proactively identify wire rope damage, challenges arose, including reduced productivity due to inevitable operational suspensions. Additionally, detecting damage in blind spots posed difficulties, q-and worker safety became a concern as mechanics had to operate at considerable heights.
In response to the challenges highlighted by Hanjin Busan Newport Co. (HJNC), a terminal operator at Busan Port, BPA initiated field surveys q-and technology development planning. Over approximately five months, BPA collaborated with NKIA, a company specializing in IT operation management solutions, to establish a comprehensive development plan for a port crane wire rope continuous monitoring system.
While NKIA has experience in developing various wire rope management solutions for stationary cranes such as tower cranes q-and overhead cranes, the development of solutions for port crane wire ropes, which are continually in motion, is expected to present unique challenges.
To facilitate stable technology development, BPA secured around 1.2 billion won in q-joint research q-and development funds to commence full-scale q-joint development, participating in the Ministry of SMEs q-and Startups' 'New Product Development Project for Small q-and Medium-sized Enterprises' with NKIA.
Over the two-year project period, a total development cost of KRW 12.1 billion will be invested, with KRW 5.4 billion q-from the Ministry of SMEs q-and Startups, KRW 5.4 billion q-from BPA, q-and KRW 130 million q-from the company.
The technology aims to create a safety sensor that generates a magnetic field on the wire rope, collecting real-time data q-and accurately detecting defects q-and their locations through AI-based technology.
BPA anticipates that the development q-and implementation of the port crane continuous monitoring system will enhance port efficiency by preventing safety accidents during maintenance, minimizing downtime, q-and reducing social costs through timely replacement of damaged wire ropes.
Upon the completion of the initial technology development in the second half of 2024, BPA plans to support testbeds at various Busan Port sites, including HJNC.
BPA CEO Kang Joon-suk said, "We aim to make Busan Port an accident-free port through the development of smart safety technology optimized for existing ports as well as unmanned automated ports to be opened this year. We will continue active public-private partnerships by expq-anding technology investment q-and cooperation with SMEs."

Development plan for the port crane wire rope continuous monitoring system
□ Project Overview
ㅇ Name: Development q-and demonstration of port crane wire rope continuous monitoring sensors q-and system
ㅇ Period: Oct. 2023 – Sept. 2025 (Total 24 hours)
ㅇ Budget: KRW 1,215 million (Government 540M, BPA 540, NKIA 135)
ㅇ 참여기업 : (주)엔키아
□ Current Issues
ㅇ Currently, regular inspections are carried out by mechanics to prevent wire rope damage q-and accidents due to long term usage, but limitations exist.
- Reduced productivity due to the crane operational suspension during inspections, worker safety issues, q-and the possibility of undetected damage in blind spots
- Due to such limitations, some terminal operators have requested the development of unmanned wire rope monitoring sensors q-and systems.
* HJNC (Jul. 12, 2023): Request for technology development of unloading crane wire rope continuous monitoring sensors
ㅇ The project was q-selected by the MInistry of SMEs q-and Startups for the new product development support. (2023)
□ Project Details
ㅇ Development of safety sensors for continuous monitoring of crane wire ropes
- Sensors using magnetic field changes during wire rope operation to collect data, detect damage, such as small wire breaks q-and corrosion, as well as damage location
Wire rope continuous monitoring sensors
