Siemens Water Technologies has been contracted to supply 14 electrocatalytic chloropac sodium hypochlorite generating systems to Samsung Heavy Industries (SHI), a leading shipbuilder. The systems will then be installed on separate LNG carriers for three petrochemical companies by SHI.
The chloropac systems will assist in preventing marine growth in the main components of the seawater cooling systems in the carriers, including sea chests, piping, coolers, and heat exchangers. Vessel capacities range from 155 000 m3 to 266 000 m3. The chloropac systems were specified for their ability to treat varying seawater flowrates of 2800 m3/h - 5000 m3/h, with continuous sodium hypochlorite dosing levels of 0.2 ppm - 0.5 ppm.
The first system was delivered to SHI in May, with subsequent deliveries scheduled throughout this year and next.
