Discuss Your Repair ProjectIn-Situ Marine Machinery Repair: 180,000 DWT Capesize Main Journal Salvage
When a fully laden 180,000 DWT Capesize bulk carrier suffered critical main journal bearing failure along a major shipping lane, JUKO MARINE deployed a specialized emergency engineering team to perform complex in-situ orbital re-polishing at open anchorage—eliminating drydocking costs and preventing massive demurrage penalties.
180,000 DWT Bulk Carrier Main Engine Bearing Emergency
Carrying over 170,000 metric tons of iron ore, the vessel reported severe thermal spikes across its main engine journal bearing. Extreme heat caused localized babbitt metal wiping and micro-surface scoring along the crankshaft journal. Standard shipyard protocols would have dictated towage to a drydock facility, cargo offloading, and extended drydocking supervision—exposing the shipowner to daily demurrage penalties exceeding $45,000 alongside substantial off-hire losses.
- Vessel Type: Capesize Bulk Carrier (180,000 DWT, Fully Laden)
- Machinery Defect: Babbitt thermal wiping & heavy main journal surface scoring
- Operational Threat: Impending engine seizure, fairway obstruction & severe demurrage
2-Hour Rapid Mobilization & Specialized Technical Logistics
Upon receiving an urgent notification from the vessel's technical management team, JUKO MARINE activated its emergency vessel troubleshooting protocol within two hours. Our technical coordinator synchronized clearance with maritime port authorities, customs brokers, and specialized tool suppliers to launch portable orbital machining equipment, metrology instruments, and custom undersized shell bearings directly to the anchorage site.
Emergency Deployment
Rapid dispatch of senior marine engineers and portable machining rigs directly to open anchorage.
Fast-Track Logistics
Seamless offshore work permit clearance, customs approval, and Class surveyor coordination.
In-Situ Precision Machining & Class Society Compliance
Executing afloat marine machinery repair demands micro-inch precision to avoid crankshaft misalignment or structural compromise. JUKO MARINE mounted custom pneumatic orbital grinding and polishing equipment directly to the main engine bedplate inside the crankcase. Our engineers re-polished the damaged journal surface to strict OEM surface roughness tolerances while recording continuous alignment and deflection metrics.
Core Engineering Execution Steps
- • NDT & Structural Inspection: Conducted liquid penetrant inspection and hardness testing to confirm thermal stress limits and shaft integrity.
- • Orbital Micro-Polishing: Precision-ground and polished journal surface finish down to original manufacturer tolerances ($Ra le 0.4,mutext{m}$).
- • Undersized Bearing Fitting: Custom-fitted precision undersized bearing shells and adjusted oil clearances to exact specifications.
- • Class Society Sign-Off: Coordinated real-time dynamic load trials with the attending Class surveyor for immediate sea-trial endorsement.
Quantifiable Performance & Commercial Impact
By avoiding towage, cargo discharge, and emergency drydocking, JUKO MARINE delivered an afloat marine machinery repair solution that restored full main engine operation within 72 hours. This timely intervention saved the vessel owner 9 full days of potential off-hire downtime and hundreds of thousands of dollars in emergency operational expenses. In addition to technical repairs, our comprehensive ship-supply operations ensured essential replacement components were delivered directly to the crew on-site.

Who Handles Classification Society Approvals and On-Site Survey Coordination?
JUKO MARINE lead technical support engineers manage all technical documentation, inspection protocols, and survey scheduling required by major classification societies. On-site project supervisors collaborate directly with attending surveyors from DNV, ABS, LR, BV, CCS, and ClassNK to present repair procedures, verify material certificates, and oversee non-destructive testing (NDT).
Comprehensive internal quality audits are conducted before official surveyor attendance. This systematic approach yields a 99.8% first-time survey approval rate, preventing costly delays and ensuring immediate endorsement of seaworthiness certificates.
How Are Voyage and Shipyard Repair Costs Structured to Prevent Hidden Surcharges?
Commercial transparency is fundamental to our ship repair workflow. Prior to commencing work, JUKO MARINE provides itemized commercial quotations detailing fixed engineering labor rates, component pricing, specialized equipment rentals, and port access fees.
If hidden machinery wear, structural fatigue, or unmapped damage is uncovered during equipment teardown, our team issues a formal engineering variation report. No additional work or material expenses are incurred without prior written authorization from the vessel manager or technical superintendent.
What Quality Guarantees and Technical Warranties Cover Completed Repairs?
Every voyage repair, main engine overhaul, and drydocking supervision project executed by JUKO MARINE carries a standard 12-month comprehensive quality warranty. This guarantee encompasses all technical execution, reconditioned components, and installed materials provided by our engineering teams.
Should operational anomalies arise during the warranty period, global mobile technical teams deploy immediately to the vessel's next port of call to perform root cause analysis and corrective repairs at zero additional cost to the shipowner.
