Sub6HLX

Overview

Sub6HLX is Effee's robotic welding repair solution for corroded, water-backed steel hull structures with material loss, corrosion pitting, and remaining wall thickness below 6 mm. Built on qualified welding procedures, robotic execution, and class-aligned quality assurance, it delivers a repeatable, in-service repair that permanently extends asset life – without cofferdams, dry-docking, off-hire, or production interruption. Remote operations reduce offshore crew to 2-3 people. Digital twin and traceability link every weld parameter, NDT record, and inspection result to the asset's digital twin.
