Which of the following requires approval by both the Inspector and the Engineer when used on a vessel?

• A. Fillet weld patch
• B. Non-penetrating nozzle
• C. Full encirclement lap band
• D. Weld overlay

Answer: (C)

The full encirclement lap band is a reinforcement method that encompasses the circumference of a vessel and is used to repair or reinforce areas that may be compromised or susceptible to failure. Given the significance of this repair method, it necessitates a collaborative approval process between both the Inspector and the Engineer. Their joint approval ensures that the design and implementation of the reinforcement meet safety, engineering, and regulatory standards. The Inspector is responsible for ensuring compliance with codes and industry standards, while the Engineer evaluates the design's integrity and suitability for the specific application. This dual oversight helps verify that the full encirclement lap band is appropriately designed, executed, and assessed in relation to the vessel's operating conditions and structural requirements, thereby ensuring safety and functionality in the long term.
