spaces



Use of Ro-ro spaces for fuel storage in mobile tanks

►

Hazardous areas

►

The Draft Part A-1 of the IGF Code is addressing safety measures for

natural gas fuelled ships as follows:



Ship design and arrangement

Fuel containments system



Material and general pipe design

Bunkering



Fuel supply to consumers



Power Generation [including propulsion and other energy converters]

Fire safety



Explosion protection

Ventilation



Electrical installations



Control monitoring and safety systems

Bunkering operations

►

Bunkering operations are not covered by IGF Code.

►

Other standards are to be considered:



ISO “Guidelines for systems and installations for supply of LNG as fuel to

ships” (ISO/TS 18683) prepared by Technical Committee ISO/TC 67,

Tank arrangement for gas only installations

Number of tanks

►

IGF draft: 9.3.1 For single fuel installations the fuel supply system shall

be arranged with full redundancy and segregation all the way from the

gas tanks to the consumer, so that a leakage in one system does not

lead to loss of propulsion and/or power to essential consumers.

►

9.3.2 For single fuel installations (gas only), the fuel storage should be

divided between two or more tanks. The tanks should be located in

separate compartments.

Gas safe machinery spaces vs. ESD concept

►

Arrangement of gas plant in machinery spaces : 2 possible solutions



Gas safe machinery spaces : double walled piping system and monitoring of

the primary barrier integrity. 4 arrangements possible:

• prevent gas leakage

• gas leakage occurs but is contained and detected: • leakage towards inert gas

• leakage towards air • leakage towards vacuum

GREENSHIP CONFERENCE PARIS 13 NOV 2014

Tank location - gas fuel tanks below accommodation

►

Gas

► Location of the tanks below accommodations is not precluded by the Interim Guidelines MSC.285(86).

► Tank location has been one of the most contentious and debated issue within the industry. ► Quite mandatory for some projects (e.g. passenger ships or ferries).

► According to Draft IGF Code, LNG fuel tanks can be located below accommodations provided that risks are properly identified and addressed

.

USCG Policy Letter 01-2012

Tank location – distance from ship side

►

Interim Guidelines : requirements similar to IGC Code



Passenger ships: B/5

Other ships: 760 mm

►

Are these requirements suitable for any type of gas fuelled ship?

►

Question was asked to IMO Sub-Committee in charge of stability (SDC)

►

SDC 1 outcomes : 2 possible approaches:



Deterministic

Probabilistic

Shall be protected against mechanical damage.

On open deck shall ensure sufficient natural ventilation.

Shall be protected from external damage caused by collision or grounding with

minimum distance of B/5 or 11.5 m. For passenger ships: B/10.

Alternatively, following calculation method may be used to determine the

acceptable location from shipside: fCN = fl x ft x fv

Length shall not exceed [9][12]% of ship's length for passenger ships and

[12][18]% for cargo ships.

Lowest boundary shall be located above the minimum distance of B/15 or 2.0

m.

Shall be aft of transverse plane at 0.08L measured from forward perpendicular

for passenger ships, and abaft of collision bulkhead for cargo ships.

f_CN reflects the probability that the damage is not extending within the tank boundaries.

► Crashworthiness may also be recognized.

IGF 5.3.5.6 : For ships with a hull structure providing higher collision and/or grounding resistance, fuel tank location regulations may be specially considered in accordance with section 2.3 Alternative Design of this Code.

Experience from « Paul Kayser » LNG carrier grounding

►

Grounding in June 1979 (Strait of Gibraltar)

►

Important deformations of the insulation, second barrier damaged

►

Primary barrier remained tight

IGF Tank location – different submissions

►

Norway (SDC 1/24 and MSC 94/11/3):

► 1. Proposing probabilistic approach as an alternative to deterministic approach (SDC1/24).

► 2. Proposed tank length 9%Lfor deterministic approach and fcn = 0.01 for passenger ships and 12%L and fcn = 0.02 for cargo ships (SDC1/24)

► 3. Proposal for considering a longitudinal distance [0.3Ls] for non-overlapping fuel when calculating fcn (MSC 94/11/3)

►

France (SDC1/24/5 and MSC 94/11/5):

► Supporting the probabilistic approach but with fcn = 0.02 for passenger ships; and fcn = 0.04 for cargo ships (SDC 1/24/5 and MSC 94/11/5)

► SDC 1 working group based on the proposals in SDC1/24 and SDC1/24/5 propose: ► The following two options should be decided on:

21

GREENSHIP CONFERENCE PARIS 13 NOV 2014

►

Bahamas, Canada and the United Kingdom (CCC 1/4/2):

► 1. It is proposed that the probabilistic calculation method is not included in the IGF

Code and reference is made to the existing SOLAS provisions.

► 2. United Kingdom drew attention to existing provisions under SOLAS to allow LNG fuel tank location closer to the side of a ship by providing justification through Alternative

Design & Arrangement (AD&A) provisions, as noted in section 2.3 of the draft IGF Code.

►

Canada, the Marshall Islands and the US (MSC 94/11/7)

► 1.Do not agree to directly align the deterministic option with the probabilistic provisions

► 2.No provisions to limit the tank length when the tank is located inside the

minimum offset from the side shell

.

►

Marshall Islands (MSC 94/11/17):

► 1.No provisions to limit the tank length when the tank is located inside the minimum offset from the side shell.

► 2.Probabilistic approach, produces results similar to the deterministic method. There is evidence that it produces an equivalent level of safety for fuel tank placement in larger gas fueled ships and its application should be limited to ships over 100 metres (Ls = 100 m). ► 3.Prefer the smaller values for Fcn

►

Germany (MSC 94/11/18):

► 1.Outcome of validation calculations performed so far by different member states does not support the proposed draft provisions entirely.

► 2. There needs to be a discussion on whether the risk of a collision and its consequences should be looked at solely or possibly the combination of accidental situations and normal operation of the fuel tanks taking into account tank size and tank location in order to lead to a single criterion or multiple criteria to be included in the IGF Code.

► 3.Finalize the first version of the IGF Code containing the tank location criteria as

per the Interim Guidelines

► 4.Further work on different kinds of gases and low-flashpoint fuels in order to widen the scope of the IGF Code;

► 5.Allow the relevant Sub-Committee to have an in depth appreciation of the proposed risk-based provisions for tank location.

LNG Bunkering – Situation in Europe

► Netherlands

 Up to now only inland shipping could bunker LNG. But Rotterdam is offering the

possibility to bunker LNG as fuel for ocean going ships based on a specific and case by case approach.

► Belgium

 In Zeebrugge, LNG bunkering by barge will be possible by the end of 2016. GDF SUEZ,

Mitsubishi and NYK will develop the LNG bunkering market through an LNG bunkering vessel to be built by Hanjin Heavy Industries. LNG bunker by truck is practised on

case by case.

 Antwerp Port Authority is continuing its focus on LNG with the aim of setting up a

permanent bunkering station at the port by the beginning of 2016. Truck-to-ship bunkering is already possible at the port – a truck collects LNG from the import terminal in Zeebrugge which is then delivered to the barges on the quayside.

LNG Bunkering – Situation in France

► DUNKERQUE LNG, Air Liquide and Exmar make up the consortium that presented its

successful project during a Call for Expressions of Interest (CEI).

 As part of the project, Dunkerque LNG and Air Liquide will be responsible for the

preliminary studies, the engineering and investments.

 Exmar will handle the preliminary studies, the engineering and the building of a

bunkering vessel, the capacity of which is yet to be defined according to LNG requirements.

*

► NANTES – SAINT NAZAIRE

 Elengy is bringing on stream the liquefied natural gas (LNG) road tanker loading

station at the Montoir de Bretagne LNG terminal.. It thereby enables its energy supplier customers to come and load road tankers with LNG, for onward transportation to the point of use. The product then serves to supply industrial users or outlets for the distribution of LNG fuel for vehicles or vessels.

Initiatives from IACS

►

In July 2014, IACS decided to launch a Project Team on development of

Unified LNG Bunkering Guidelines with the following objectives :

 Elaborate a set of guidelines for ensuring the safety of LNG bunkering operations.  Help to develop the LNG bunkering process by providing an unified regulatory

framework in a tentative for clarity and homogeneous level of safety

 Consider a voluntary submission to IMO in view of adoption by the Industry.



The objective is to deliver comprehensive technical safety guidelines (based

on existing documentation)

- To be comprehensive and technically consistent in view of a large adoption by the Industry.

- Feed back from recent LNG bunkering incident is taken into account.

- in liaison with stake holders forum and professional associations (SGMF, IAPH, ESSF).

- Focus first on safety, not really on commercial aspects such as quality of LNG except when safety may be undirectly impacted.

BV Guidelines on LNG bunkering (NI 618)
