OceanSaver has won a contract from an unnamed South Korean shipbuilder to deliver a ballast water treatment system (BWTS) for two Suezmax lightering tankers.
Scheduled to be delivered in mid-2014 to Chevron Shipping Company, the two vessels will be equipped with the Mark II OceanSaver system, which will be fully compliant for global lightering operations in various water quality and salinity conditions.
Disinfection is achieved through the on-board generation of oxidants delivered to the ballast flow via side stream injection from OceanSaver’s C2E sea water activation module.
When the injection into the ballast water is made, the mixture of oxidants present removes unwanted organisms.
The company said that the amount of residual oxidant (TRO) is also reduced within a few hours and neutralisation is hardly required during de-ballasting.
OceanSaver senior vice president of sales and marketing Tor Atle Eiken said the BWT system offers high-quality manufacturing and materials that meet the heavy-duty operational demands of lightering operations.
"A BWT system in shuttle or lightering tanker can be operated more in two years than a VLCC BWT system would be over the life of the vessel," Eiken said.
OceanSaver CEO Houtan Houshangi said that the company has managed to lower per unit costs by 30%-40% during the past 18 months.
"Our BWT systems are more streamlined than ever, offering ship operators uninterrupted flow, continuous operation, high filtration efficiency, robust quality and long life at a very competitive price," Houshangi said.
The company currently has 52 BWT systems on order and seven in operation around the world.
The Mark II OceanSaver system is DNV type approved and has undergone DNV’s approval programme for installation and safety standards.
