The construction is to be built according to the drawing with rules of good workmanship and to be built the longitudinal frame system.
The construction is of rolled Steel Pipe sections with varying wall thickness, from40mm to 150mm, which are carefully manufactured and checked to ensure roundness, straightness, segment connection deflection within the specific tolerances.
ProcedurePre-roll bending pf plate-Rolling of cylindrical hull-Welding the vertical seam to close the section-Heat treatment-Rolling to correct ovality-Assemble of the several pipe sections-Assemble with accessories(Sheave, expansion part etc.)
All fabricated steelwork used in the construction of the spud will be to manufacturing standard of classification society BV, GL, LR, DNV
All steel used to be blasted and shop primed both sides. Using DH36 and D690
