Harland and Wolff, the Belfast shipyard that built the Titanic, was put into administration on Monday after its bankrupt Norwegian owner failed to find a buyer and calls for its nationalization were rebuffed.

The shipyard, whose towering yellow cranes dominate the Northern Irish city¡¯s skyline, has been occupied by workers fearful for their jobs since last week. They said on Monday they would block administrators from entering the site.

¡°BDO have been appointed as administrators and the company will file for insolvency tomorrow,¡± a Harland and Wolff spokesman said.
