Norwegian ballast water treatment (BWT) provider Optimarin has signed a fleet contract with the UK shipowner and management company Carisbrooke to incorporate its optimarin ballast system (OBS) into the latter’s fleet.
Under the contract, which is claimed to be Optimarin’s biggest ever, the company will introduce its ballast system into the UK firm’s entire fleet of 46 bulk and multipurpose vessels.
The installation work is expected to commence next year in the Carisbrooke fleet of vessels ranging in size from 5,000 to 20,000dwt.
The OBS is modelled on filtration as pre-treatment and high doses of UV irradiation to eradicate any traces of viruses and bacteria without hindering the normal functionality of the vessel.
The system is fully approved by IMO and certification through DNV GL, Lloyd’s, Bureau Veritas, MLIT Japan, and American Bureau of Shipping.
An ensuing United States Coast Guard (USCG) approval for Optimarin, scheduled later this year, is said to have paved the way for the deal.
Carisbrooke fleet technical director Martin Henry said: "There were multiple factors at play. USCG compliance is critical for our trading routes, as is the operational and supply chain reliability of the technology itself.
"However, people are also key.
"Their expertise, and the modular nature of the system, will be essential when it comes to retrofitting vessels with small engine rooms and very limited available space.
"We believe this to be an excellent UV system, at a very competitive price, from a supplier with a genuine maritime heritage and understanding.
"This gives us complete peace of mind for future regulatory compliance, technical dependability and, importantly for Carisbrooke, environmentally responsible operations."
Last month, Optimarin was awarded a contract to provide its ballast systems for nine anchor handling tug supply (AHTS) vessels being built at China’s Sinopacific Shipbuilding Group.
The contract had followed a ten unit order from Turkish shipping firm Atlantis Tankers for two newbuilds and eight existing vessels.
