Attention
For the sake of safe operation of the chain as part of the berthing facilities make sure that the strength characteristics of the shackles used for installation comply with the chain strength characteristics.
The chain is used in the fenders of berthing facilities designed also for mooring large-capacity ships.
For the sake of safe operation of the chain as part of the berthing facilities make sure that the strength characteristics of the shackles used for installation comply with the chain strength characteristics.
