Star NCLC, part of the Genting Hong Kong group, and the TPG Viking Funds, the US investor, are planning to sell a total of 12.5 million shares in Norwegian Cruise Line Holdings, the world’s fourth largest cruise shipping group.

“The Company will not receive any proceeds from the sale of these ordinary shares by the selling shareholders,” the company said in a filing with the Securities and Exchanges Commission in the US.

The news comes in the same week as two senior Genting Hong Kong officials announced their resignation from the board of  the Norwegian group. Genting earlier this week acquired Crystal Cruises, the luxury cruise operator with two ships from Tokyo based Nippon Yusen Kaisha (NYK). Crystal is a competitor of Norwegian group’s Regent Seven Seas brand.
