Major Overhaul of a Vessel

SHIP REPAIR
ABOUT
Professional Restoration and Service Life Extension
Major vessel overhaul is a set of activities aimed at fully restoring the vessel’s technical and operational characteristics to values as close as possible to the original specifications. It includes replacement or restoration of any components, including basic hull structures and machinery.
Vessels operate under high-stress conditions: saltwater, temperature fluctuations, wave impacts, and mechanical vibrations. Over time, structures wear out, leading to the following consequences:
  • Reduced strength of the hull and mechanisms
  • Increased risk of failures and accidents
  • Higher fuel and maintenance costs
  • Deterioration of conditions for crew and passengers
Major overhaul helps restore the vessel's capacity, extend its service life, and bring safety levels back to standard.

Specmorservice performs major overhauls on vessels ranging from fishing and service vessels to passenger and cargo ships — in strict compliance with the requirements of RMRS, RRR, NKK, RINA, and BUREAU VERITAS.
