Underwater Fabrication, Welding And Installation Services

Leos Maritime provides expert underwater welding, fabrication and installation for offshore and marine industries. Using wet and dry hyperbaric techniques, we repair and install pipelines, ship hulls, oil rigs and harbor structures efficiently and safely.

Where Are These Services Used?

Underwater fabrication, welding and installation are vital for maintaining and constructing critical subsea infrastructure:

  • Offshore oil and gas platforms require structural repairs, reinforcements and equipment installation.
  • Underwater pipelines involve corrosion patching, leak sealing and new pipeline tie ins.
  • Ship hulls and propellers can undergo emergency welds and component installation without dry docking.
  • Bridge piers and harbor facilities need fabrication, strengthening and equipment mounting.
  • Renewable energy installations include subsea foundations, supports and cable installations.

Types Of Underwater Welding

Our certified welders perform both wet and dry welding methods:

  • Wet welding is fast and economical for urgent repairs using SMAW or FCAW.
  • Dry hyperbaric welding provides high quality precision welds using TIG, MIG, SMAW or FCAW.
