Reducing Marine SOx Emissions: An Inter-Industry challenge Refineries need significant investment to fully deliver compliant fuel post 2020/2025 Up to 2015 Fuels been delivered with the conventional production methods Post 1 Jan 2015 and up to 2020/2025 Increasing pressures on supply Competition with land based distillate pool New refinery streams for 0.10% RM grades From 2020/2025 VLSFO 0.50% RM grades of fuel, price and quality Outlet for residual fuels EGCS uptake S>3.5% to be monitored
Increase demand for Distillates and ULSF Residuals Source: Marine and Energy Consulting Limited Global emissions legislation resulting in increased demand for distillates between now and 2020 The grades demanded are ISO 8217 for sulphur content of 0.10%: DMA/Z DMB RMA The scope for new RM grades was not fully realised until 2014: The engines most impacted burn residual fuel All that is required is: S 0.10% and RMG /K compliant fuel 2018?
2015 ULSFO (<0.10%) - 5 Categories 1. Ultra Low Sulphur Residual Fuel Oil 2. Blends of Distillate + small amounts of residual fuel oil 3. Heavy distillates, fuels with low metal content but with higher viscosity than conventional DMA CIMAC Working Group 7 - Fuels (International Council on Combustion Engines) Convention for low sulphur fuel oils: LSFO = 1.0% VLSFO = 0.50% ULSFO = 0.10% Each may include any of the 5 categories of fuel composition 4. Distillates DMB and DMA 5. Alternative fuels and power sources

Compatibility and Stability Operations Individual stability generally satisfactory High risk of incompatibility with other RFOs Oxidation stability (where applicable) satisfactory (DM) Total Sediments (where applicable) satisfactory But thermal loading? Fuel ageing? Load in empty tanks Carry out compatibility test Always monitor filter loading during change over Lloyd s Register GMT Ltd - FOBAS
