U.S. Bankruptcy Judge John Sherwood, who issued an order barring seizure of Hanjin property by creditors, acknowledged that some details remained unresolved and urged the parties to "self-help" and work out problems among themselves. That could prove thorny. Hanjin has identified 14 U.S.-bound ships in bankruptcy filings, including the Hanjin Greece and two other vessels currently near the Southern California coast. Port operators, cargo owners, longshoremen, shippers and others all must reach financial agreements with Hanjin before each ship can be docked, officials said.
