May be limit the temperature (i.e well below threshold temperature ) for 316 L
application?
However, I won`t prefer using SS 316 instead GRP could be an option provided
that velocity is not high.

The failure is not due to flow disturbance if an SS pipe is used for
sea wtaer service. The concern is SCC. And the moment it starts,
failure is sure to happen - its just a matter of time. There are
other pipe material that is suitable for use for sea water
application . One is a cement lined CS pipe (coated and wrapped for
U/G application) or fiberglass pipe - both have a pretty good
service life.
