SPECIALIZED SERVICE
Scope and capabilities in marine maintenance
We provide direct technical assistance to vessel owners, agents, and port operators requiring responsive mechanical servicing and welding interventions.
The maritime sector demands swift, grounded technical action, as port turnaround times for commercial and service vessels are governed by strict operational windows. At MASEG, we plan each onboard task to minimize downtime.
Our scope encompasses structural hull and frame repair via specialized welding, mechanical overhaul of shaft lines and rudder bearings, custom lathe machining, and the servicing of hydraulic maneuver circuits.
Key operational highlights:
- Specialized welding on hull plating, bulkheads, and superstructures
- Applied marine mechanics: propulsion lines, rudders, and gearboxes
- Lathe machining and fitting of bushings, couplings, and shafts
- Servicing of hydraulic circuits and deck maneuvering machinery

TECHNICAL FAQS
Frequently asked questions on marine maintenance
Do you perform interventions while the vessel is afloat?
Yes, we undertake mechanical and structural maintenance on board while berthed dockside, provided the scope does not strictly mandate drydocking.
What welding processes do you employ for structural steel repairs?
We utilize specialized shielded metal arc (SMAW) and semi-automatic (FCAW/GMAW) welding on marine-grade steels, emphasizing rigorous root preparation and continuous bead inspection.
Do you service other port facilities beyond Valencia?
Our operational base is in Valencia, regularly attending requirements across Mediterranean port corridors depending on scope and scheduling.
How do you handle hot-work safety clearance on board?
We strictly adhere to port authority and vessel management protocols, obtaining necessary permits and stationing dedicated fire-watch equipment.
