Losses at Fred Olsen Cruise Lines deepened in the second quarter of the year, figures from Norwegian holding company Bonheur show.

The line, which operates four ships, saw fares drop by 3% year on year while fuel prices rose by 6%.

Net losses increased to NOK 56 million from NOK 42 million in the same three months in 2013.

The operating result dropped into the red with a loss of NOK 8 million against a profit of NOK 9 million a year earlier.

Net losses for the first six months of the year deteriorated from NOK 88 million to NOK 102 million despite revenues rising from NOK 726 million to NOK 795 million.

“The UK cruise market’s weak economic conditions continued to result in lower sales,” Bonheur said.

The number of passenger days in the quarter totalled 274,605 against 316,468 in the same period in 2013.

Fred Olsen Cruise Lines owns and operates the ships Black Watch, Braemar, Boudicca (pictured) and Balmoral.

Bonheur is one of the two listed companies of the Olsen family that jointly own the Ipswich-based cruise line.
