Air Emissions Regulations Update Tripartite meeting 15/16 September 2006; Seoul dragos.rauta@intertanko.com
IMO DEVELOPMETNS • Annex VI entered into effect in 2005 • US possible ratification of Annex VI • Baltic Sea - SECA from May 2006 • North Sea - SECA in November 2007 • Proposals for significant amendments to Annex VI discussed at the IMO
Proposals for significant amendments to Annex VI • Lower limits for SOx and NOx emissions • New SECAs • NOx emission limitation on existing engines • NECAs – NOx controlled areas • Restriction on CO2 emissions • Restriction on Particulate Matters (PM) emissions • Restriction on VOC emissions from cargo oil tanks
REGIONAL DEVELOPMENTS • Europe Sulphur Directive adopted in 1999 with significant amendments entered into force in August 2006. EU Directive governs inter alia emissions in port. • California (CARB) is establishing new regulations to take effect in 2007 • Various ports (e.g. Rotterdam) are facing new local regulations on Ship Emissions, which are inhibiting future expansion/development
ALTERNATIVE SOLUTIONS • “Clean” fuels and/or alternative solutions such as: • Exhaust gas scrubbers - Scrubber technologies are not yet proven and have their own environmental as well as economic and availability challenges • SCRs – technologies yet to be proven as reliable • “Cold ironing” - with associated problems including the lack of an international standards for voltage/frequency of power, of shore/ship connection systems and compatibility with shipboard requirements for power supply for hydraulic power sources (compressors needing up to several MW of power) • Etc.
DISCUSSIONS Under debate is: • To identify areas that would be impacted by these regulations • Whether Tripartite could address design and equipment/installation solutions to facilitate compliance with these new sets of regulations • Whether the Industry should develop a common strategy
AREAS OF CONCERN • Fuel oil storage & associated piping: • Increase storage capacity for LSF • Complete segregation of HSFO and LSF/MDO tanks • Additional 3rd storage tank for 0.1% S fuel • Additional storage for lower BN number lube/cylinder oil • Manifolds modifications for bunkering & fuel sampling • Scrubbers: • Space for installation (big space required in the ship’s funnel) (calculations shown need up to or over 2,000 cub.m/h of water) • Pumps (big capacity) + pipes • Storage tank for solid waste • Water waste treatment plant (hydrocyclons, etc.)
AREAS OF CONCERN • SCRs: • Space + pipes (one SCR for each engine) • catalyst (ammonia!!) storage • changes air intake to the ER and accommodation/ammonia slip) • Pipe/pump bearing of stainless steel (no copper!), etc. • In engine solution (e.g. HAM – water treatment plant and storage – usage of roughly same amount of water as fuel) • VOC: • New installation/equipment (e.g. KVOC + VOCON) • COT designed for higher pressure (e.g. > 2000 mmH2O on p/v valves)
AREAS OF CONCERN • PM: • filters on the exhaust pipe after the scrubber • Non-corrosive material • Class rule? • Etc. • CO2 control: • Propeller design • Hull roughness • Windage coefficients • Other solutions to reduce fuel consumption/hp
CONCLUSION TO BE FORMULATED AFTER TRIPARTITE DISCUSSIONS
