Panama Canal

PanamaInitial Recovery Phase Completed

Passenger Vessel Recovery & Stabilization in Panama

Client: Confidential shipowner

A laid-up passenger vessel with an extensive and initially fragmented repair scope underwent comprehensive technical assessment and stabilization. TESS coordinated multidisciplinary inspections and specialist contractors, prioritized critical defects, supported the restoration of essential machinery required for a safe condition afloat, and converted the findings into a phased long-term recovery program.

  • Comprehensive vessel condition assessment and defect prioritization
  • Essential systems addressed to establish a safer, technically controlled condition afloat
  • Multiple specialist contractors coordinated through one technical interface
  • Phased engineering roadmap developed for long-term vessel recovery
