The company would be prepared to pay a 20 percent premium to Hamworthy’s last traded price, or 825 pence per share.
“Wärtsilä believes that the combined resource and competence base would improve the potential in the Offshore markets, help to capture a bigger share of the growing marine gas application market as well as create a stronger position within the rapidly evolving environmental solutions markets,” the company said in a press release.
Wärtsilä must announce the offer to the UK authorities by December 15 at the latest.
