Orders to the Watch (prior 1970) Wash down bilges with chemical cleaner and pump dry prior to entering port. In port pump all bilges on the midwatch. Pump down waste oil tank prior to entering port Dump all garbage; remember to hole containers so that they sink Blow tubes on the midwatch; remember to notify the bridge and lookout 3
Orders to the Watch (prior 1970) Preheat diesels before getting underway to reduce annoyance of smoke and soot to topside personnel Dump ballast water prior to fuel barge alongside; remember to minimize overboard discharge of oil from SW displacement tanks by continuous sounding of tanks Chip and paint portside air castle; sweep down all debris; save empty paint cans for target practice 4
On Going Legislation December 2009 Conference of the Parties (COP15) in Copenhagen IMO continues greenhouse gas (GHG) regulation Hold annual increase in global temperature below 2 degrees C $30 billion in climate funds for least developed countries Unresolved: reduce GHG by 50% in 2050 Upcoming March 2010 IMO Marine Environment Protection Committee (MEPC) in London regarding: market based mechanisms Cap and trade Bunker levy Energy efficiency design index Need all parties involved (designers, builders, owners, operators, vendors, Administration) to make legislation effective 5

Proposed US Emission Control Area US and Canada requested IMO to designate US and Canadian coast as ECA including Pacific, Atlantic, Gulf of Mexico and 8 main Hawaiian Islands ECA would extend 200 NM from coastal baseline After consideration, and if adopted entry into force (EIF) as early as August 2012 Impact after entry into force: Fuel oil sulfur content 1.0% (12 months after EIF), down to 0.1%, after 2014 New engines to meet reduced NOx emission standards 8
ABS Operational CO2 Index Know where you are Operational index voyage specific: g of CO2 emitted (based on fuel burnt) t of cargoes carried * N-M traveled Design index design specific: g of CO2 emitted (based on specific fuel consumption) Design cargo capacity * Design speed Various deduction allowed in numerator: Innovative technologies that reduces fuel consumption CO2 capture Weather factor allowed in denominator: improving hull shape 9

SOx Limits: EU Requirement to use 0.1% sulfur level in fuel used when in EU ports effective 1 January 2010 Many ships unable to comply due to lack of availability of parts from suppliers 21 December 2009, the EU Commission recommended Member States take account of any detailed evidence of efforts to comply with the Directive by ships EU Member States may consider the existence of an approved retrofit plan when assessing penalties It is up to each EU/EEA Member State to how they choose to respond to the EU 11
Complying with New Emissions Limits Various options exist or are under development to reduce NOx or SOx emissions (some methods reduce both) NOx emission reduction technologies: Internal engine modifications (30-70% reduction) Water injection (humid air engine) (65-85% reduction) Exhaust gas recirculation (30-70% reduction) Selective catalytic reduction (SCR) (90-95% reduction) SOx emission reduction: Exhaust gas cleaning (scrubbing) (90-99% reduction) Switch from HFO to MDO (40% reduction with 1.5% MDO, 80% reduction with 0.5% MDO) 12
SOx Emission Reduction: EGCS Exhaust gas cleaning systems: approved to MEPC.170(57) Guidelines for Exhaust Gas Cleaning Systems Guidelines specify requirements for the testing, survey, certification and verification of EGC systems System approved subject to either: Periodic parameter and emission checks Continuous emission monitoring When EGC system is operated in ports/harbors/estuaries, discharge water ph, turbidity, nitrates not to exceed limits Washwater residue to be delivered shore reception facilities 13
SOx Fuel Switching News: 1 October 2009 Low sulfur fuel causing power loss (Motor Ship) The US Coast Guard and international shipping lines are becoming seriously alarmed at the number of ships suffering loss of power after switching to low sulfur fuel. This is particularly the case in California where the state ordered all ships (with a few special exceptions) from July to use a maximum of 1.5% marine gas oil (or 0.5% marine diesel oil) within 24 nautical miles off the coast. From January 2012 the limit for both types of fuel goes down to 0.1%. According to the Coast Guard, six ships suffered complete loss of power in July, out of 720 arrivals, compared with 11 out of 8,600 arrivals in the nine months before that. Even more worrying, San Francisco Bar Pilots say they have seen an incident every one to three days, some involving engine starts while at berth, due to insufficient air pressure or lack of fuel suction, leading to delays of a couple of hours. 14
Can Technology Change the Game? Single system for CO2, NOx and SOx Test results show almost 100% removal of NOx and SOx Test results indicate substantial reduction (35-50%) in CO2 First units now being fitted to newbuildings 15
