Re: Bolts as Fuse Link

[Subject Prev][Subject Next][Thread Prev][Thread Next]
While this is not my area of expertise, the following thoughts are offered:

What happens to the dolphin after the bolt shears?
Is the docking ferry then no longer functional?
How easily can the bolt(s) be placed?
Who will be available to determine the bolt has sheared and needs to be
replaced?

David Finley, P.E.
