JUMP TO FULL CODE CHAPTER
For new MOTs or berthing systems, a minimum of three quick-release hooks are required for each breasting line location for tankers greater than or equal to 50,000 DWT. At least two hooks at each location shall be provided for breasting lines for tankers less than 50,000 DWT. Remote release may be considered for emergency situations.
All hooks and supporting structures shall withstand the minimum breaking load (MBL) of the strongest line with a safety factor of 1.2 or greater. Only one mooring line shall be placed on each quick release hook (N/E).
For multiple quick release hooks, the minimum horizontal load for the design of the tie-down shall be:
| Fd | = | Minimum factored demand for assembly tie-down. |
| n | = | Number of hooks on the assembly. |
The capacity of the supporting structures must be larger than Fd (See Section 3107F.5.3).
