Optimarin proves reliability of its BWT systems

OPTIMARIN, a supplier of compliant ballast water treatment (BWT) technology for vessels, has given a demonstration of its long-term system reliability on board Neptune Subsea's IMR vessel Larissa.

The 334 m3 capacity system onboard the SX130 Ulstein design Larissa was installed during its construction by Zhejiang Shipbuilding in 2010. Since then it has only seen 140 hours of operation, a statement from Optimarin said.



Given its prolonged idle time, CEO Per Ivar Fagervoll of Golden Energy Offshore, which manages the ship for owner Neptune, thought Optimarin may have had work to do when it visited Larissa during a recent stop in Stavanger.



"When the Optimarin team came on board we thought it might have issues. Little did we know - the guys pressed the 'start button' and it came into action immediately - smooth operation and no problems at all," said Mr Fagervoll.



Optimarin's visit coincided with the publication of a report from ABS that highlighted 42 per cent of BWT systems - from a sample of 220 installed units, across 27 shipowners - were seen to be problematic or not working at all.



"The BWT sector is maturing," commented CEO at Optimarin Tore Andersen, "but some suppliers have seen it as a business opportunity, rather than an area demanding specialist focus and expertise.



"Optimarin has been exclusively focused on developing simple, flexible, reliable and compliant systems since 1994, installing the world's first commercial unit in 2000. Last year we became the first manufacturer to achieve full USCG (US Coast Guard) approval. This is a way of life for us, not a means to 'make a quick buck'.



"The system onboard the Larissa is typical. It has no moving parts, requires minimal maintenance and is flexible enough, thanks to its modular nature, to fit any specialist vessel," added Mr Andersen.
