The document discusses the challenges in designing extreme lock gates for the Third Set of Locks project. It describes the unique characteristics of the lock gates, including withstanding 250,000 operating cycles, floating without additional support, and allowing wagon replacement in under 4 hours. It outlines the innovative solutions developed for the lower wagon assembly, load limiting device, and sealing system. The document also covers seismic design considerations and testing to ensure the gates can withstand earthquakes.

Employers Requirement:
Each of the wagon attachments to the gate shall be designed to allow
wagon replacement in less than 4 hours.
Traditional lower wagon design:
•Floating of gate: 8-16 hours
•Divers operation: Lock unavailable

17. Guiding Bearing and Sealing
Employers Requirements:
Leakage: The maximum allowable leakage rate per meter of lock gate seals and
sealing surfaces at any point shall not exceed 10 liters/minute when the gate is
subjected to normal and maintenance operating conditions. The overall average
leakage rate per meter of lock gate seals and sealing surfaces shall not exceed 5
liters/minute.

• Engineering of scales has its limits
• Crossing these often requires innovation
• “Borrowing” from other fields or disciplines can be a good
method to find interesting, precedented solutions
