Weir Group will reduce its headcount by a further 400 jobs overseas as it looks to reduce costs.
The company said it expects trading conditions remain challenging through the fourth quarter of the year with further declines in oil and gas exploration and production.
The valve and pump maker said it was also feeling pressure as a result of lower mineral prices.
Weir plans to make around £25million worth of cost savings which will include additional workforce reductions and service centre consolidations.
Around 140 jobs are going in its oil and gas division in North America while a further 225 jobs will go from its mineral division in Africa and some in Australia.
A further 40 jobs are expected to be lost from its operations in China.
Chief executive Keith Cochrane said: “”The challenges in our end markets intensified during September and October.
“Looking ahead, we expect trading conditions to remain challenging through the fourth quarter with further declines in upstream oil and gas activity.
“We will focus on delivering further cost and procurement savings, alongside strong cash generation.”
Weir has reduced its oil and gas workforce by 37% over the past 12 months.
Meanwhile its total global workforce has been reduced by more than 10%.
