Poseidon Med anatomy
POSEIDON MED is the first Cross European Border project which aims to introduce LNG
as the main fuel for the shipping industry and develop a sufficient infrastructure network
of bunkering value chain.
It focuses in the eastern Mediterranean region with five Member States (Cyprus, Greece,
Italy, Croatia and Slovenia) involved.
It is a partnership between gas suppliers , shipping companies, Port Authorities, Technical
organisations etc.
It is officially included in ‘Juncker package’ Candidate projects.
Objectives of Activity 5
• The objective of this activity is to complete a risk assessment and establish risk
acceptance criteria which will address hazards and operability issues related with
LNG as a marine fuel.
• Risk qualification will be presented as a product of the likelihood (frequency) of any
adverse occurrence, and the impact of such an adverse effect (consequence).
So, what is risk?
Hazard
something with the potential to cause an adverse consequence
e.g. a flammable material
Consequence
harm as a result of a hazard being realised
e.g. fatality from ignition of a flammable material
Likelihood
the chance that the consequence occurs
e.g. a frequency of 1 in 100 years or a probability of 0.01
Risk:The chance that something bad happens - a combination of hazard likelihood and
consequence

Vessels Retrofit
Risk Assessment on vessels retrofit and installations: 6 vessels under investigation
The overall scope of work for the risk assessment of the vessels involved in the study should cover the
following as a minimum:
LNG fuel system and bunker station on-board the receiving ship
Bunkering system and offloading station on-board the bunker tanker
The 6 pilot vessels under examination are:
• Cruise ferry: “FESTOS PALACE”, of Minoan Lines
• Cruise Ferry: “SUPERFAST I”, of Superfast
• High Speed Passenger ferry: “HIGHSPEED 6” of Hellenic Seaways Maritime SA
• Modern Pure Car Carrier : “NEPTUNE GALENE”, of Neptune Lines
• Converted Car Ferry: “ARIADNE” of Hellenic Seaways Maritime SA
• Typical Cargo Vessel: “MARINE LEGEND I

ARBD Questionnaire sub sections
• The questionnaire that was used during the Vessels workshop focused on the following
issues:
A. Fuel Tank – Protective Distance
B. Fuel Tank – Below Deck – Fuel tank within a Fuel Storage Hold Space (FSHS)
C. Tank Connection Space (TCS) – Below Deck
D. Fuel Preparation Room (FPR) – Below Deck
E. Fuel Tank – On-Deck
F. Tank Connection Space (TCS) – On-Deck
G. Fuel Preparation Room (FPR) – On-Deck
H. Pressure Relief Valves (PRVs)
I. Gas Valve Unit (GVU) / Gas Regulation Unit (GRU) – valves regulating supply to consumers
J. Master Gas Fuel Valve (MGFV)
K. Bunkering Station (BS)
Methodology used
• Screening reports workshops facilitated by
LR experts:
The workshop uses a pre-prepared question
set developed by LR as part of its process to
screen the suitability of designs and
arrangements for “gas as fuel”
Rule criteria follow the LR rules for the
classification of Natural Gas Fuelled ships
and the IGF code
Based on the outcome and comments of the
screening reports an Approval in Principle will
be issued for the vessels.
Vessels Installations
• Key Technical issues
Tank Connection Space arrangements ( Categorisation of spaces)
Vent location
Bunkering rates and operations
Tank arrangements in relation with IGF provisions
Standardising connections and manifolds
Shiptype influences decisions (double hull or high speed , small size)
Vessels Installations
MINOAN LINES – FESTOS PALACE ARBD
Workshop
• Completion of the 69 point questionnaire of the
ARBD process
• Despite an ambitious enclosed space tank location,
no major showstopper identified
• Points for further consideration were among other
the vent location and the tank connection space
access arrangement
Vessels Installations
• SUPERFAST FERRIES – SUPERFAST I ARBD
Workshop
• Completion of the 69 point questionnaire of the ARBD
process
• An opendeck arrangement of LNG tanks, no major
showstopper identified
• Points for further consideration were the vent position as
well as SIMOPS and exclusion zones
• Improved alternative tank arrangements could result
from this consultation
• Major showstopper identified in relation with the exact
port layout and operations, this alarmed us , triggered a
preliminary review
Vessels Installations
• NEPTUNE LINES – NEPTUNE GALENE
• Completion of the 69 point questionnaire of the ARBD
process
• Arrangement of LNG tanks, in car decks 1-2, no major
showstopper identified, favourable conditions for retrofit
• Points for further consideration were the vent position as
well as SIMOPS and exclusion zones, point identified for the
bunker station
• Improved alternative tank arrangements resulted from this
consultation
• First Gas Retrofit Concept Survey onboard a Greek vessel
• Conclusion, A good design to proceed with!
Vessels Installations
• HELLENIC SEAWAYS– HIGHSPEED 6
• Completion of the 69 point questionnaire of the ARBD
process
• Case revealing problems identified for smaller ships
• Bunkering station proximity to LNG tanks , Exclusion Zone
requirements constitute a potential showstopper
• Conclusion, more focus to be shed on small designs
Posts Infrastructure
The aim of the risk assessment will be to cover the
significant components that are addressed during the design
of a new LNG infrastructure. The main aspects that will be
covered are:
• Bunkering System and off-loading station for the
receiving ships
• Storage and bunkering procedures
• Examination of the bunkering system design
arrangement (position, lay-out,
• Structural integration, equipment)
• Exclusion zones
The result of this sub-activity will be a report (HAZID)
including risk assessment of bunkering and off-loading
station for the receiving vessels, risk assessment of the
exclusion zones and risk assessment on the storage and
bunkering procedures.
HAZID Methodology
Compliance with the following:
• ISO 31010 Risk Assessment Techniques
• open group discussion with all team specialists having a direct input into the proceedings under the
direction of the HAZID Chairman.
• Site Evaluation Review. Address specific site issues related to the proposed location for bunkering operations
• Ranking of identified Risks. Critically address potential risks, prioritize using risk ranking methodology and
establish best options available for bunkering operations at port
HAZID Methodology
The evaluation process included the following:
• Undertake a site investigation in order to asses existing/proposed candidate bunkering locations and assess general
area layout
• Identification of potential hazards associated with the LNG bunker barge port approach and berthing alongside for ship-
to-ship (STS) bunkering operations at proposed jetty(s). Address impact on existing ship traffic management at port.
• Identify potential hazards associated with LNG bunker truck operations and jetty-to-ship (JTS) bunkering operations at
proposed jetty (s). Address traffic impact of LNG trucks in the wider Limassol Port area.
• Identify potential hazards associated with the proposed options with regards to the shore location, installation and
operation of a future LNG storage facility which can provide replenishment to both bunker barge and/or bunker trucks
operating within Port Authority areas. Critically compare between the two operations.
• Assess the adequacy of the proposed marine facilities, jetty facilities and the proposed bunkering storage layout design
for ensuring the safety of the surrounding area; establish the Regulatory requirements for project compliance.
• Perform a round table discussion of potential failure mode scenarios and emergency response procedures and critically
assess potential societal impact.
Port Infrastructure
• Establishing Safety in Piraeus Port
• Based on the findings of the HAZID study, the supply
infrastructure and the proposed LNG bunkering operations
judged not to present any intolerable risks, not any risks
significantly greater than those found to be acceptable for
conventional fuel bunkering operations at ports.
• The major events of marine failure, truck transportation
failure, LNG bunker transfer failure, LNG/gas release, and
control/isolation failure have been considered in all aspects
of the proposed operations and appropriate mitigation
measures were identified to reduce the risks.
Port of Piraeus HAZID study
• The study identified a number of potential
operational and bunkering system drawbacks
which could cause a reduction in operational
safety.
• However, it is accepted that specific risk critical
issues will be further mitigated by Risk
Assessment activities during Poseidon Med
phase II and that Piraeus Port Authority, based
on the experience gained, will establish LNG
Bunkering Procedures in order to identify the
minimum system specifications, operating
requirements, safety checklists and competence
levels to be met.
Port of Limassol HAZID workshop
• The intended scope of the Site Evaluation HAZID study was to apply a rigorous format of
examination to the proposed area(s), facilities, ship types, equipment and operational
activities in order to identify the best bunkering operational solution
• and to demonstrate that all credible accidental events have been considered and appropriate
mitigation procedures are in place to ensure safe operations.
Port Infrastructure
• Establishing Safety in Limassol Port
Layout particularities of Port, envisaged offshore
support area
Difficulties in adapting current port operations to LNG
Defining responsibilities between port, coastguard and
other authorities , case of Emergency
Other barriers:
Cypriot legislation barriers identified during workshop,
customs procedures
In the next phase more detailed scope is anticipated:
• Building of a pilot vessel LNG fuelled vessel for Venice Port
(1st in the Mediterranean)
10+ vessels approval in principal and detailed review including both new buildings and
retrofits
Continuation and follow up of the regulatory framework from Poseidon Med regulatory
framework gap analysis results
Studies and risk assessment in 5 ports
Shipyard preparedness
Working towards sustainability – next steps ahead
