LNG as fuel is one of the solutions for reducing air emissions
NOx emissions reduced by more than 80% (for lean burn engines)
SOx emissions eliminated (no sulphur in LNG).
Particulate matters are close to zero.
CO2 emissions are reduced by approx 20% (unburned methane if any should be taken into account as its global warming potential -GWP- is more than 20xCO2).

8 INTERTANKO Alternative Fuels WG 12th February 2015
The number of LNG-fuelled ships in the world fleet is still limited and mostly located in ECA
zones. The number of ships is steadily increasing.
The adoption of LNG as fuel Is expected to take off with the 2020 sulphur cap and the
unlocking of the LNG bunker chain.
A limited part of the world fleet

LNG as fuel development crucial points
10
Development / investments in infrastructures
Legislative / regulatory binding framework
Harmonizing standards & encouraging innovation
Business model & Financials support
LNG as fuel will further develop if following needs are satisfied:
A visible and understanble regulatory framework is crucial for the development the market as investors are put at regulatory risk.
Harmonization of standards to establish a true global market and a fair competition specifically for LNG as fuel design (IGF code will be a binding regulation but did not enter into force yet) and LNG bunkering
absence of a realistic business model. The additional costs of retrofitting or new-building of LNG is perceived as too high compared to the expected long-termin savings.

12 INTERTANKO Alternative Fuels WG 12th February 2015
LNG Safety record at sea : more than 50 years
1962:
Supervision of the prototype tests of the experimental LNG carrier "Beauvais", and first Rules for LNG Carriers published by BV.
1965:
Classification of "Jules Verne", 25,000m3 LNG ship.
1971:
Classification of "Descartes", 50,000m3 LNG Carrier, Technigaz type

A safe and reliable energy facts & figures
LNG accounts for more than 30% of international trade in natural gas.
70,000 legs without loss of cargo and accident, about 140,000 loadings and unloading operations.
Strong rules and standards, deep technical knowledge and safety culture have made this industry one of the safest.

Feasibility assessment
Assistance for review of predesign solutions, such as the choice of type of engines and tank technology to fit the expectations and operational constraints of the project at the earliest stage,
Definition of the LNG tank location(s), size and arrangement and range in gas mode based on the operational profile and the bunkering frequency,
The Safety concept will include:
a preliminary HAZID of the design,
a list of prescriptive requirements for a LNG as fuel project vessel according to last draft IGF Code or Interim guidelines (as per Flag requirements) and BV NR 529 will be established, such as additional A60 fire safety requirements, cofferdam, safety distances and hazard areas classification requirements.

Hazard identification study (HAZID)
An HAZID workshop is performed in order to fulfil the requirements stipulated in the IMO MSC.285 (86) or the Draft IGF Code, and in the NR529. The objective of the HAZID workshop is to ensure that the safety and operational risks of the fuel gas installation of the project are eliminated or reduced to as low as reasonably practicable (ALARP). It will cover but be not limited to the following subjects:
LNG storage tanks,
Vaporization Unit,
LNG bunkering stations and procedures,
Fuel gas piping;
Engine Room arrangement;
routing of the fuel gas piping,
Position of the different ventilation inlets & outlets as well as the vent lines, bleed lines and associated vent masts.
Simultaneous operations risk assessment (when appropriate).
