Wastewater treatment business Nature Group has been awarded a large contract for the offshore treatment of waste oil slops generated on board a Floating Production, Storage and Offloading vessel (FPSO).The group, which will be employed by one of the oil majors off the coast of Brazil, saw its share price rocket more than 15% after making the announcement. The company said: "This contract underpins the ongoing efforts in marketing Nature's compact treatment unit technology into the oil and gas market. "The contract is for the treatment of oil waste currently collected on the FPSO and ensures the oil major a substantial cost saving compared to onshore treatment. Nature's solution also ensures that all recovered oil can be re-used by the oil major." It is the second new contract for Nature's compact treatment unit (CTU) technology within a month, leaving the company confident that its CTU technology will contribute to the continued growth of Nature's revenues and activities in the oil and gas market.The group said that although the value of the contract cannot be disclosed, it will contribute significantly to a positive return for Nature's oil and gas division, following on from the recently announced contract in Norway. The share price was up 15.84% to 58.50p at 09:14. NR
