GB/T 37335-2019

This standard provides design guidelines for ensuring the structural integrity of full penetration welds in self-elevating drilling units (jack-up rigs). It is applied in the shipbuilding and offshore engineering industry, specifically for the design and construction of leg-to-hull connections and other critical load-bearing areas where complete weld fusion is required to withstand extreme operational and environmental stresses. The standard is used by engineers and procurement professionals to specify welding procedures, inspection criteria, and quality control measures for these high-risk zones.
