Ships with scrubbers can continue to burn 3.5% sulfur heavy fuel oil (HFO). In a seawater system the sea's natural alkalinity largely neutralizes the results of SO2 removal before discharge back to the sea. Except for very low fuel consumption ships (<10t/day) installing scrubbers is likely to cost less than doing nothing. Installation requires dry docking the ship which will take it out of service (and therefore off-hire) for 2-3 weeks. Scrubbers save Carnival ships in Alaska $150,000 a week.
