Fabrication isometric for a 6″ NB vent line spool, specifically designed for the Valaris DS-4 MGS vent lines on Leg 4. This drawing provides detailed dimensions for spools 10 & 11, including vertical runs of 9000mm and 8350mm with skew offsets.. The pipe finish is specified as galvanised with strict inspection requirements including 100% CVI and 100% MPI NDT. Notable features include a 45° cut back at the open end and specific top dead centre (TDC) measurements of 560mm. The layout includes skew boxes to define pipe orientation in 3D space. This technical spool drawing is intended for specialized offshore or marine piping fabrication.
