Leading the way; making a difference

Operations in ECAs (SOx)

Tripartite

16/17 October 2015

Ian Harrison

Senior Technical Manager


Emission Control Areas (ECAs)

• European Union Directive Follows IMO except: – After Jan 1, 2020 – 0.50% in EU waters

• California

– After Jan 1, 2014 – 0.10% (24 miles)


• INTERTANKO/OCIMF Recommendations on Fuel Change Over Procedures

• API Technical Considerations for Fuel Switching

• CIMAC Guideline for Operation of Marine Engines on Low Sulphur Diesel

HAZID to avoid mechanical failure & power loss


Experience: Pilots reporting erratic response


“We have had a rule for years regarding vessels which cannot do

posted maneuvering RPM’s or pitch. These vessels become

daylight with a tractor tug escort being the pilot’s

prerogative. With the new LSFO requirements we have had a

higher than usual amount of vessels falling into this

category. We will be strictly enforcing this rule, as we feel it is

imperative that all vessels transiting our ship channel are

capable of doing their full range of posted maneuvering speeds.”

From Agents advising local pilot’s views:


• Propeller curve (power versus rpm) is slightly different due to bigger diameter

• For same Delta in rpm the corresponding Delta in power is bigger

• Could affect manoeuvring and performance in heavy weather

Experience: new ECO Ships


• From 1 Jan 2016 Requires…

• 10% of ships to be inspected

And of those, a percentage to be tested:

• (a) 40 % in Member States fully bordering SOx Emission Control Areas (SECAs);

• (b) 30 % in Member States partly bordering SECAs;

• (c) 20 % in Member States not bordering SECAs.

And

• As from 1 January 2020, in Member States not bordering SECAs, the sulphur content of the marine fuel being used on-board shall also be checked by sampling or analysis or both of 30 % of the inspected ships

EC Implementation Decision (for Dir. 1999/32/EC)


• Sulphur Inspectors should take the on-board spot sample of marine fuel through a single or multiple spot sample at the location where a valve is fitted for the purpose of drawing a sample in the fuel service system… • be easily and safely accessible

• take into account different fuel grades being used for the fuel-oil

combustion machinery items

• be downstream of the fuel in use from the service tank

• be as close to the fuel inlet of the fuel-oil combustion item as feasible and safely possible taking into account the type of fuels, flow-rate, temperature, and pressure behind the selected sampling point

EMSA Sampling Guidelines


3.58 Following discussion, the Committee:

.1 instructed PPR 3 to initiate the work on development of guidelines for onboard sampling and verification of the sulphur content of the fuel oil used on board ships; and

.2 agreed that a proposal for associated amendments to MARPOL Annex VI would constitute a new output and would, therefore, require a relevant proposal from a Member Government, in accordance with the Guidelines on the organization and method of work …

MEPC 68 on Sampling Guidelines


• In practice, there is no quality control of bunkers delivered to ships except for the testing arranged by ship operators

• Bunker Alerts issued by test laboratories every week

Bunker Quality


Norway and INTERTANKO collected data from two fuel testing laboratories which together had more that 50% of all bunker deliveries worldwide

• Out of over 100,000 bunker samples, the receiving vessels have reported that on 1,468 occasions they have had machinery problems as a result of using the fuels as supplied.

• These were events resulting in

machinery damage and

black out events

Bunker Quality


New Fuels/Blends/Hybrid

• Co-mingling issues (<2% with residual)

• Detergent effect

• Specifications not yet included in ISO 8217

• Requires heated tanks

• Compatibility issues

ECAs – LSFO (0.1% S) Potential Issues


Cold Flow Properties of Distillate Fuels


Reg. 18, MARPOL Annex VI - Fuel Oil Availability and Quality

• Fuel oil . . . shall meet the following requirements: • shall be blends of hydrocarbons derived from petroleum

refining

• shall be free from inorganic acid

• shall not include any added substance or chemical waste which:

- jeopardizes the safety of ships or adversely affects the performance of the machinery, or

- is harmful to personnel, or

- contributes overall to additional air pollution

Bunker Quality


MEPC 67 Correspondence Group:

• develop draft guidance for assuring the quality of fuel oil delivered for use on board ships

• consider the adequacy of the current legal framework in MARPOL Annex VI

• Round one complete: – Following “best practice” approach

– Includes guidance for supplier, users and Member States

– For fuel delivered to ships

Bunker Quality


• More novel fuel solutions (Hybrids)

– Compatibility

– Handling and storages

– Safety

• Back to blending problems (as with 1% S limit)?

• More efficient, cleaner engines - technical solutions needing cleaner fuel…

• Fuel Quality not just an operational issue – it’s a design issue

2020 and Bunker Quality (0.5% S)
