Submarine Biofouling Control- Chlorination DATS Study at Pearl Harbor
Abstract
The intent of this document is to sumarize the chlorination studies performed at Naval Station, Pearl Harbor in support of biofouling control initiatives for the submarine community, as requested by NAVSEA 92T. The document is a compilation of the status reports, as well as a comprehensive summary of the data collected/analyzed reviewing the concerns and recommended approaches for the submarine community on the implementation of chlorine to control biofouling at Pearl Harbor. The Naval Research Laboratory (NRL) has been investigating and developing chlorination methods to control biological fouling (biofouling) in ship seawater systems. As part of these efforts, a Deposit Accumulation Testing System (DATS) was installed at the Sierra 15 mooring site in SUBASE Pearl Harbor. The DATS test was designed to evaluate the accumulation of biofouling on heat exchanger materials in environments representative of shipboard conditions. This was accomplished by measuring the change in heat transfer resistance on a model heat exchanger tube due to the buildup of biofouling over time. The DATS test in Pearl Harbor was used to evaluate the effect of biofouling on titanium heat exchanger materials being implemented on the MOD-25 SSN 688 class submarines homeported at Pearl Harbor as well as to establish chlorination levels, for control of biofouling. This test will also assist in the determination of dechlorination requirements chemical injection rates to ensure an environmentally acceptable chlorine discharge into Pearl Harbor.
