NSPS Deputy Ministers Governance Committee Meeting
Transcript of NSPS Deputy Ministers Governance Committee Meeting
Shipbuilding Stages of Construction • Fabrication
– Cutting of parts from raw material – Forming of parts
• Subassembly – Joining of parts by welding to create interim
products up to ~20 tonnes
• Block Assembly – Assembly of 12m x 12m standard hull blocks
• Pre-Outfitting – Installation of outfit on hull blocks
• Blast and Paint – Abrasive blasting for surface preparation – Coating of hull structure and outfit items
• Pre-Erection – Joining of blocks to create grand blocks
• Erection – Erecting and joining of grand blocks to create
the vessel
