Transcript of STC-NMU Masterclass LNG in shipping - moving towards a paradigm shift?
Master Class April 3, 2014
The use liquefied natural gas (LNG) as ship fuel has raised the interests of many shipping and shipbuilding companies around the world. There are three important drivers which make LNG as ship fuel one of the proactive future technologies for
shipping lines: reduction of considerable emissions (SOx, partially CO2), perceived costs benefits of LNG compared to heavy fuels. However, the shipping industry seems to be reluctant to broadly embrace LNG and make investments in their fleets. At this Master Class experts from Damen Shipyards, Anthony Veder, Port of Rotterdam, and
STC-Group will explore the latest developments on ship technology, finance, regulations and facilities.

Marpol Annex VI Sulphur regulations
General Requirements (Resolution MEPC.176(58), 2008)
• The sulphur content of any fuel oil used on board ships shall notexceed the following limits:– 1 4.50% m/m prior to 1 January 2012;– 3.50% m/m on and after 1 January 2012; and– 0.50% m/m on and after 1 January 2020.
• While ships are operating within an Emission Control Area, the sulphurcontent of fuel oil used on board ships shall not exceed the followinglimits:– 1.50% m/m prior to 1 July 2010;– 1.00% m/m on and after 1 July 2010; and– 0.10% m/m on and after 1 January 2015.
Results
• For any fuel used on board, global sulphur must bereduced to 0.5% from January 1, 2020.
• Reducing environmental harm caused by ship emissionsimposes large costs on ships, particularly when operating in emission control areas.Source: Jiang, Kronbak, & Christensen, 2014

The need for regulations
• As the sulphur in fuels burn, it will form SOx, which is oneof the pollutants to the environment especially in the formation of acid rain. Continued exposure over a long time changes the natural variety of plants and animals in an ecosystem. Also the sulphur content in fuel oil has a large impact on the particle level in the exhaust gas.
• Ships have options to reduce sulphur emissions in the ECA’s.

Low sulphur fuels
• Switch to low sulphur fuel oil or destillates No capital costs High price (+30 – 50%) Not attractive for charterer/cargo owner Blending needs to be done carefully
• ‘Loss of power’ incidents• Change-over between HFO and MDO / MGO (Compatibility, thermal
shocks, gassing of hot gas oil)

• The pay back period is about 2,5 years and for more large vessels event is less .
• The payback time is more sensitive to HFO price if the vessel operates longer inside ECA’s.
• DF sys. shows sensitivity to global cap enforcement at 2020 when differential price between LNG and HFO-MGO will boom by increasing demand over MGO. (Inelasticity of demand and supply)

• Payback for the larger vessels
shows a stronger dependency on the investment than for the smaller vessels
• payback for all vessels shows at
higher rate of cash out but payback time is shorter for DF sys.
Conclusion
• Using LNG promises less emission and less fuel costs. LNG Vs scrubber systems for the fleet in the trade rout of Fareast to north of Europe
• With 44% ECA exposure, LNG system payback time below three years. • The dual fuel system is attractive as long as differences of LNG price
(delivered on board) to HFO is less than 150 $/ton. • For larger vessels , Eca exposure with higher than 44% , is expected to
show the shortest payback times . • Use of scrubber system reduces payback time and is more attractive
than MGO
Conclusion
• An dual-fuel offers lower fuel costs, maintenance cost and better chartering potential .
• ECA exposure is a crucial factor while the Capex plays important role in payback time & feasibility
• An LNG price of up to 550$/ton provides a competitive advantage for dual-fuel engine vs scrubbers in terms of payback in this study
• It may lead to a higher Capex but a longer period of economic depreciation. It makes economic sense for banks to confront with less risk by financing on dual fuel engine vessels.
Recommendation • For all type references vessels , dual fuel engine has higher financial
attractiveness and technically is more feasible. • If the global sulphur cap enters into force after 2025, the payback time
increases by about 1 year. • Higher 44% presence at ECA gives a less payback period when the
engines need to burn more 0.1% MGO, assuming an HFO-MGO spread of ~780$/ton.
• The LNG solution is more expensive than the scrubber solution. If LNG is also used outside ECA after 2020, the business case becomes more interesting with a payback period of less than 2.5 years with 44% ECA exposure.
• As for the scrubber solution, the payback period is most sensitive to the HFO-MGO spread. Referring to chapter predicting a limitation of price difference is difficult as the LNG infrastructure is also unknown

To remember 1. Upcoming regulations force us to take action
2. LNG offers a clear environmental benefit
3. LNG is the fastest growing prime fuel/energy
source
4. LNG is a mixture of different components
5. The mixture varies geographically
6. This reflects in different energy contents => fuel consumption
7. There are big uncertainties about price, but given the ample resources of NG and the foreseen price increase of diesel fuel due to de-sulphurization, LNG seems promising

The energy content of LNG is 1.8 time < diesel fuels ⇒ Need +/- 2 times the fuel for the same work
→ 2 times bigger fuels storage tanks OR 2 times higher bunkering frequency
Storage tanks contain LNG at -162°C and withstand +/- 10 bar pressure ⇒ Insulated cylindrical storage tanks → Hard to fit in ship design → Lots of “lost” space
Rule of thumb: 4-5 times the space required for LNG for equal bunkering
intervals

→ some parts are expensive and need regular maintenance, fouling of the engine itself is much less
Dynamic load response

Engine technologies
Lean Burn Diesel principle Otto principle
Ordinary Diesel Dual fuel Emergency Diesel Pure Gas • Intake: Air enters the engine • Combustion: Diesel is injected in the hot air and auto-ignites
• Intake: Air and gaseous fuel enter the engine • Combustion: A substantial amount of diesel is injected and auto-ignites, thereby igniting the air gas mixture
• Intake: Air and gaseous fuel enter the engine • Combustion: A small amount of diesel is injected and auto-ignites, thereby igniting the air gas mixture
• Intake: Air and gaseous fuel enter the engine • Combustion: A small pre-combustion chamber, filled with a stoichio-metric air-gas mixture is ignited by a spark

FUEL SYSTEM BACKGROUND ENGINES
To remember
1. Different engine types create uncertainty
2. Limited power ranges for NG engines make ship design difficult
3. NG engines have specific characteristics • Dynamic behaviour • De-rating • Maintenance

Safety rules
1. Prevent leak of vapour and liquid to the atmosphere
2. In case of a leak, use protection (cryogenic materials, drip trays, water curtains)
3. In case of a leak, prevent ignition (EX equipment, safety, security and exclusion zones)

A successful port of the future cannot do without a successful region and vice versa. The port needs a region that people like to live, work and recreate in.
The Port of Rotterdam Authority views LNG small sca le as an important element in achieving a sustainable shipping and a s ustainable Port.
The Port of Rotterdam Authority remains a key discu ssion partner in this respect and a connecting factor between science, go vernment organizations and the business sector.

LNG safety policy:
We have no special nautical traffic rules for LNG carriers
We have no special regulations for LNG fuelled ships.
We have regulations for LNG bunkering.
We consider an LNG tanker as a “normal” tanker carrying dangerous goods and of course we have regulations for ships carrying Dangerous Goods.
• See our admission policy
An LNG fuelled ship is considered to be a “normal” ship
• Of course we must be aware of the LNG bunker tank on board
LNG bunkering is a transfer of dangerous goods. In the Port of Rotterdam we have regulations for-, and enforcement on the transfer of dangerous goods.

LNG bunkering in the Port Bye Laws
To get this stuff on board is very demanding
• Spatial planning • Environmental restrictions• Safety requirements for LNG bunkering • Checklists• Safety distances• Minimum passing distances for other
vessels• Simultaneous activities• Accreditation of LNG bunker vessels• Accreditation for power supply vessels• Safety requirements for repairs• Operational reports

LNG bunkering in the Port of Rotterdam
• At a location with an environmental
permit
• (Shore to ship, truck to ship)
• Environmental permit based on PGS 33-2
• From a accredited LNG bunker vessel
• (ship to ship)
• With an exemption of the competent
authority

Emission policy:
• No release of LNG, or emission of NG during: • Bunkering
• Cooling down
• Purging
• De-bunkering or gas freeing
• No release of LNG during the disconnecting of the LNG bunker line
