Project Profile
Emergency Blackout Recovery & Engine Overhaul in Trincomalee
When a fully laden commercial vessel suffers a complete electrical blackout and severe engine failure at sea, the financial and operational stakes are critical.
Marine One was appointed to execute an emergency rescue and technical recovery for a vessel left adrift. After seamlessly arranging an emergency towage contract to bring the crippled vessel safely into the Port of Trincomalee, our technical division immediately mobilized to restore power, overhaul the machinery, and get the ship back on charter. This case study highlights Marine One’s ability to combine rapid emergency logistics with high-level marine engineering to solve catastrophic technical failures under extreme time pressure.
🚨 The Crisis: Situation Overview & Initial Assessment
Upon the vessel’s arrival under tow at Trincomalee, the ship was completely dark—suffering from chronic engine issues and a total failure of its power generation systems. Immediate, decisive technical intervention was required to stabilize the vessel and assess the extent of the machinery damage.
Marine One instantly deployed a rapid-response technical squad led by certified Class 1 and Class 2 Marine Engineers, supported by a full mechanical crew. Operating initially under emergency conditions, our engineers conducted a comprehensive, root-cause condition survey of:
- The Main Engine (ME)
- All Auxiliary Engines (AE)
- The entire machinery space and electrical switchboards
Strategic Execution & Technical Recovery
To minimize the vessel’s off-hire time, Marine One executed a phased recovery plan, prioritizing immediate safety and power restoration before tackling heavy mechanical overhauls.
Phase 1: Emergency Power Restoration
Without onboard power, heavy mechanical work is impossible. We rapidly procured and rigged a hired generator onboard the towing vessel, safely cabling it to the crippled ship to supply emergency temporary power. With the vessel illuminated and critical safety systems online, our electricians and engineers systematically diagnosed the electrical grid, successfully reviving and stabilizing the vessel’s own standby power systems.
Phase 2: Auxiliary Engine (AE) Restoration
To detach the vessel from emergency shore/tug power, shipboard generation had to be reliable. Our marine engineers systematically dismantled and repaired all three auxiliary engines, restoring them to operational condition so the vessel could safely regain independent electrical power.
Agile Engineering Decision: To prevent delays to the sailing schedule, the complete major overhaul of AE #2 was strategically postponed to be completed underway.
Phase 3: Main Engine Overhaul
With power stable, the team shifted focus to the crippled propulsion plant. A major overhaul was carried out on Main Engine Unit 4 and Unit 5. To ensure the engine was completely safe and sea-ready, our technicians executed critical supplementary maintenance:
- Deep cleaning of scavenge spaces to eliminate fire risks.
- Complete servicing and calibration of piston rod stuffing boxes.
- General restoration of surrounding machinery spaces.
🚢 Voyage-Ready Completion & Riding Squad Deployment
Because the vessel was laden, the charterers required it to sail immediately once the main propulsion was deemed safe. To accommodate this aggressive timeline without compromising vessel safety, Marine One deployed a specialized engineering riding crew. Our riding squad sailed with the vessel, utilizing the transit time to execute the heavy, major overhaul of Auxiliary Engine #2 while the ship was underway. Upon reaching the destination port in Singapore, the auxiliary engine was fully restored, tested, and operational, allowing our riding team to successfully sign off and fly home.
The Final Outcome
Total Recovery
Marine One successfully executed a complete vessel blackout recovery and full machinery restoration.
Zero Port Delays
By deploying a riding squad for the AE overhaul, we saved the owners days of expensive port stay fees in Trincomalee.
Safe Voyage
The fully laden vessel safely departed Sri Lanka under its own power and continued its voyage to Singapore without a single further technical delay.
