LNG carriers: the Yamal project

Construction of 15 x 170 000 m3 Arctic LNG carriers at DSME shipyard

for SOVCOMFLOT (6 vessels), TEEKAY (6 vessels) and MOL (3 vessels)

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).


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.


Class Role


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

• Classification of "Hassi R'Mel", 40,000m3 LNG Carrier of Gaz Transport 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.


Rules & Standards for ship design

IGF Code


LNG Prepared notation


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.


► Cargo ships IGC dist - no tank allowed

fCN < 0.04

No more length limitation

B/5

Passenger ships B/10 - no tank allowed

fCN < 0.02

No more length limitation

B/10

Safe Tank location


Arrangement for LNG as fuel

► Reserved spaces for LNG tank, gas chain auxiliaries and vent masts will be allocated according to designer and owner prescriptions,

► Structural reinforcement to be fitted at the earliest stage are also be part of the notation in order to facilitate the further fitting of the tank and associated heavy equipment’s,

► Impact on intact and damage stability of LNG tanks locations to be reviewed,

► Potential impact on load line and draft,

► Safety reinforcement (gas detection, additional ventilation means).

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).


RO PAX ferry LNG Prepared

► Design : Principle of segregation between gas dangerous spaces and safe spaces

No direct communication between gas spaces and non-hazardous spaces

Reinforced fire insulation of gas spaces (A60 + Cofferdam), structural reinforcements

Hazardous area classification

Segregation of piping systems

► Operations : Passengers onboard, not professionals by essence, to be informed strictly about hazardous zones (smoking areas…)

Simultaneous operation in bunkering QRA required to mitigate risk level / Restricted access for balconies, sun deck,

Quantity of LNG to be bunkered in allocated time


Technical assistance

► Specific assistance is offered to the owner and the LNG supplier for the future bunkering procedures and operations.

► AIP

As appropriate the process needed for the assignment of the notation LNG Prepared as described above is concluded by the delivery of an AIP.
