while floating upright without the
aid of additional floating
equipment, cables, or supports.

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.

Conclusions
• 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
