SECA: 1% S nu - 0,1% S in 2015.

Low sulfur: the options

• LNG• Scrubbers• HFO & MGO:• Soft switch

• New fuel types

Low sulfur: considerations

• Vessel age?• Percentage outside SECA?• SECA border crossings/year?

Some Lessons Learned• Fuel switching can increase LOP risk• LOPs most probable during inbound transit• LOPs observed on ALL vessel types • Duration/complexity of the transit matters• Routing/navigation safety implications• Preventing LOPs more cost effective than responding• Risks CAN be mitigated through effective

– Maintenance– Procedures– Training– Testing & Practice

• REMEMBER CASUALTY REPORTING REQUIREMENTS

Soft Switch advantages

• Easy change between fuels – UMS compliant• Fuel temperature gradient to meet specs• Viscosity guarded against low lubrication• Loss of power prevention• Automatic registration fuel use: prevents fines• Optimal economic use of MGO vs. HFO• Low cost, small footprint, easy to install
