Alternative futures for shipping
Shipping has used many different sources of energy
Muscles
Wind
Coal
Oil
Oil has dominated the last century, it’s now time to look for new
types of fuel. Driven by:
1. Environmental concerns – new regulations
2. Increased oil prices
3. New technologies

MGO and low sulphur oils
• Price development of MGO is predicted to rise
(EIA).
• Oil companies and refinery owners, for example
Swedish Preem, are working to deliver lowsulphur oil blends to the market before 1.1.2015,
most probably strategically priced slightly below
MGO alternatives.
• To comply with upcoming NOX regulations, EGR or
SCR technology needs to be installed on board
ships.

LNG case study
• Currently 49 ships in operation, 61 in orderbook and >100
projects discussed (DNVGL, 2014)
• Liquid methane can also be produced from bio feedstock
forming LBG
• Safety record satisfying
• New infrastructure investments required for small scale
distribution networks.
• Question of future LNG bunker price developments.
• LNG in four-stroke technologies complies with future SOX
and NOX emissions caps without extra abatement
technologies.
• Cryogenic storage tanks demanded on board vessel

LNG case study – Baltic SO2lution
• Four newbuilt tanker vessels, first to be delivered in 2016.
• First installation of 2-stroke-engine technology for LNG
complying with upcoming NOX and SOX requirements.

Global commodity (55 million tons annually)
Can be produced from various feedstock
Exiting global infrastructure
Liquid at room temperature, can be stored in similar tank
on board and ashore as oil products
Similar reductions in air emissions as LNG (CO2, NOX, SOX,
PM)
Retrofits need significantly less adjustment than LNG
Toxic
Question on price development for marine market
Today large retrofits and newbuilds planned, but still in trial
stages

Scrubber case study
• Continued use of heavy fuel oils
• Aftertreatment of fuel gases extracts sulphur
• Additional techniques needed to minimise
NOX levels in outlet gases
• Flexible solution suitable for ships without
fixed bunkering points over time
• Technically complicated, both regarding the
scrubber itself and technically for the ship

Methanol case study
• Rules are in place for methanol in the IMO IGF –code
and Class rules ( LR & DnV)
• Low flashpoint fuel like LNG
• Flashpoint Methanol + 11 C.
• FlaspointLNG -188 C.
• Self ignition Methanol+ 465 C.
• Self ignition LNG+ 595 C.
• Infrastructure and safety similar to ethanol and petrol
• Liquid –no high pressure or cryogenic storage required

Scrubber case study – Pilot scrubber
• Installation, evaluation and demonstration of
a new generation, innovative lightweight
scrubber technology in full scale on existing
Ro-Ro vessels TransAtlantic Transpaper type
and Wagenborg Schieborg, operating in the
Baltic Sea and in the North Sea.
