Water treatment systems company Scienco/FAST has announced that it has been awarded contracts to supply two of its InTank Ballast Water Treatment Systems (BWTS) for offshore service provider Vallianz Holdings. The systems will be installed on board the Holmen Pacific and Holmen Atlantic project barges.
According to the manufacturer, the filterless InTank BWTS was selected because it provides operational flexibility to semi-submersible vessels, allowing rapid in-place ballasting of floods and landfills without treatment.
The InTank BWTS is filterless and processes ballast during the trip. Scienco/FAST describes the system as a true second generation alternative to the contemporary BWTS. The system is more compatible with vessel operation than in-line systems, offering more robust processing and full control of ballast water compliance, the company said.
“Vallianz put care and planning into InTank’s selection, performing detailed engineering reviews to ensure smooth installation, practical vessel operation and ballast water compliance,” said Scienco/FAST, a subsidiary of BioMicrobics Inc.
Scienco/FAST said it worked with Vallianz as well as local InTank representatives, Coffin Turbo Pump and BWTS retrofit specialist UniBallast, who completed another InTank survey and integration engineering package, to assessment of the suitability of Vallianz vessels.
The 16,600 dwt Holmen Atlantic and 34,400 dwt Holmen Pacific are submersible launch barges built in 2012.
The vessels are the latest of several rigs, barges and semi-submersibles to be selected from InTank, Scienco/FAST noted. Recently, seven InTank systems have been installed on board HL semi-submersible Boskalis vessels.
