When it's multiple somethings and it's not time critical (days or weeks rather than hours), it's economically far more sensible to ship by sea.
Sure, a service centre could really need half a dozen flights of engines, but given how well planned aircraft maintenance is, it would certainly be a turn up for the books to suddenly need such a number so urgently.
Four of their planes have been in SFO in the past week:
RA-82081 was in SFO on April 28 and flew to Kinston, South Carolina, then continued on May 2 to Nantes, then Leipzig.
RA-82074 arrived in SFO on April 30 from Milan MXP via Goose Bay, then from May 2-4 flew to Kinston, Nantes, and Chateauroux.
RA-82047 was in SFO on May 2, and flew to Columbus OH, then to Everett WA.
RA-82077 landed in SFO on May 3, arriving from Tokyo via Anchorage, then flew onto Kinston the next day.
