Azerbaijani oil officials say one worker has been killed and nine others are missing after part of their offshore oil installation broke off in strong winds.

Azerbaijan’s State Oil Company known as SOCAR, reported that 10 workers were swept away after a 150-meter (490-foot) section of walkway fell into the Caspian Sea during 90 mph (145 kph) winds.

Azerbaijan President Ilham Aliyev’s office said in a statement that “at the current time, the body of one of the missing workers has been found and that Search and rescue operations are continuing for the remaining nine.”

A spokesperson for SOCAR said five of the victims had been working on the installation and another five were in a cabin which was dislodged by the high winds.

Senior oil official Balmirza Agarahimov said that 10 boats were in the area carrying out the search, which would continue for a long time despite storm and snow conditions.

He added that the structure that was destroyed by the winds had been built in 1978 and had last undergone repairs in August.

The incident comes just over a year after Oil and Gas people broke the story of the worst oil disaster in the history in Azerbaijan’s history, when a fire and lifeboat sinking on the Guneshli oil platform left 32 workers either confirmed dead or lost without a trace.
