The Gordon Martin-led Coogee Chemicals has bought a terminal next to its Kwinana facilities from Gull Petroleum in a deal valued at nearly $40 million.
As first flagged by WA Business News last week, Coogee this week finalised the deal for Gull's terminal, which has a total storage capacity of 58 million litres.
Fuel stored at Gull's terminal is distributed to metropolitan and regional customers across the state.
It is not known whether Gull will still use the facilities or why the sale took place, and comment was being sought from Gull chief executive Wayne Ferrell.
Mr Gordon has previously told WA Business News that Coogee was not interested in Gull's retail business.
Coogee's Kwinana operation is the largest multi-purpose bulk liquid dangerous goods terminal in WA with a capacity of 68,000 cubic metres, which handles hydrocarbon solvents, alcohols and caustic corrosive products.
