In 2014, approximately 2,628 metric tonnes is estimated to remain in service for a 30-year lifetime of ships. This would provide on average a little less than 300 metric tonnes annually through 2023. For a 40-year lifetime of ships, 3,775 metric tonnes of residual halon 1301 is estimated to remain in service in 2014. This would provide on average a little less than 200. Figure 8-1.
