Aug 27 (Reuters) - Shipping services group Clarkson Plc (CKN.L) reported a lower first-half operating profit but in line with its expectations and said that trading since the end of June remained in line with its view.

The company said while the market recovery was still uncertain, it expected to ship in excess of 7 billion tonnes of cargo in 2009, slightly less than the average for the past four years.

"Overall transaction numbers have risen in comparison to the same period last year, albeit at rates that are substantially lower," Chief Executive Andi Case said in a statement.

For the six months ended June 30, the company posted an operating profit of 11.6 million pounds ($18.8 million), compared with 17.7 million pounds a year earlier.

Revenue fell to 88.9 million pounds from 118.1 million pounds, reflecting weaker shipping markets, both in terms of chartering rates and asset values across broking and financial activities, it said.

Clarkson shares were up 4.7 percent at 675 pence at 0844 GMT on the London Stock Exchange. ($1=.6170 Pound) (Reporting by Balachander Surianarayanan in Bangalore; Editing by Gopakumar Warrier)
