Major Alternator Overhaul & Crane Recertification at Anchorage

Marine alternator overhaul · engine-room crane recertification24/7 anchorage attendance
Completed

Scope of Work

  • Complete alternator disassembly and extraction of heavy components, including stator casing and rotor handling, with barge support
  • Heavy-lift handling of components weighing approximately 4 tonnes under round-the-clock operations
  • Coil resistance measurements, insulation testing and diagnostic verification of the exciter and alternator windings
  • Mechanical servicing, electrical troubleshooting and control-system inspection of the engine-room service crane
  • Static and dynamic proof-load testing using a calibrated load cell for crane recertification

Project Outcome

Ocean7 Maritime executed the alternator overhaul and crane recertification at anchorage through continuous coordination between the vessel, workshop, barge, rigging and technical teams. The required electrical checks, heavy-lift handling and proof-load testing were completed successfully while keeping vessel downtime to an absolute minimum.

Main engine air cooler servicing24-hour turnaround
Completed

Scope of Work

  • Removal of a heavily choked main engine air cooler while the vessel remained at anchorage
  • Hoisting and transfer of the air cooler ashore for servicing
  • Workshop cleaning and servicing of the air cooler core
  • Logistics coordination between vessel, workshop and supporting partners
  • Return transport and lifting of the serviced air cooler back onboard

Project Outcome

Ocean7 Maritime coordinated a one-stop response for a vessel at anchorage experiencing a heavily choked main engine air cooler. The unit was removed, transferred ashore, serviced and returned onboard within approximately 24 hours, minimizing disruption to the vessel's schedule.
