Concurrent execution of hull coatings, rudder overhaul, and propeller shaft mechanical works.

How to minimize downtime and maximize vessel operational lifespan through integrated scheduling.

Master Schedule: Synchronizing Contractors and Ship Crew

A standard 14 to 21 day drydock intervention brings together dozens of specialized trades competing for the same crane capacity and workspace.

Constructing an hourly Gantt schedule with crystal-clear critical path identification (hydro-blasting, propeller removal, tank steel replacement, and hydrostatic testing) prevents cascading delays.

Daily morning stand-up coordination meetings between MASEG site managers, the owner's superintendent, and shipyard safety coordinators resolve technical interferences quickly.

Mechanical Overhauls in Propulsion and Steering Systems

Pulling tail-shafts, rudders, and mechanical face seals requires precision hydraulic pullers and seasoned mechanics capable of taking micrometer tolerance readings.

Laser alignment of the shaft line and hydraulic nut tightening of the propeller boss are decisive milestones supervised jointly with classification surveyors.
