UPDATE 1-FMC Tech tops Wall St estimates, ups 2009 outlook

* Q3 EPS 73 cents vs 63 cents expected by Wall St

* Increases 2009 guidance, sees Q4 EPS of 70-75 cents

* Q3 revenue fell 3 pct to $1.09 billion

SAN FRANCISCO, Oct 27 - FMC Technologies Inc posted on Tuesday an unexpected rise in quarterly profit due to strong demand for its subsea oil and gas processing systems, and increased its full-year outlook.

The company said its backlog was $3 billion, including $2.4 billion in subsea systems, though that was down slightly from $3.1 billion at the end of June.

Third-quarter net income rose to $91.6 million, or 73 cents per share, from $82.7 million, or 64 cents per share, in the same quarter a year ago. Revenue fell 3 percent to $1.09 billion.

Analysts had expected 63 cents a share on revenue of $1.04 billion, according to the averages on Thomson Reuters I/B/E/S.

The Houston-based company said it now expected fourth-quarter earnings from continuing operations to be in a range of 70 to 75 cents per share, implying full-year guidance of $2.83 to $2.88 per share, versus an average $2.65 a share expected by analysts.

The company said in July it expected 2009 diluted earnings per share from continuing operations to be in a range of $2.55 to $2.65.

FMC shares have jumped 137 percent in 2009, more than double that of the Philadelphia Stock Exchange oil service index .OSX>.
