Filosofía general

Antecedentes, motivación, presupuesto…
Objetivos marcados.
Gas Safety philosophy is a chain composed of three links
Aprobación de proyectos de gas natural en buques
Filosofía general
► The HAZID study will identify risks linked to the specific system and the
consequences on / from the surrounding on this system
► The FMECA study will identify critical failure modes inside the system or
equipment giving a picture of reliability of this system
► The HAZOP study will verify the safety and operability of units design

Other studies: Gas dispersion
analysis
► Gas dispersion analysis: might be required on case by case basis
depending on the HAZID result


potentially for TCS, fuel gas preparation room, bunker stations, vent mast.
Guidance shall be developed for this kind of analysis (what do we wants to
demonstrate? On which scenario can we base these analyses? Which type of
modelisation?)
Explosion analysis
► No explosion analysis required except

if required in IGF : 5.6.5 ESD protected machinery spaces separated by a
single bulkhead shall have sufficient strength to withstand the effects of a
local gas explosion in either space, without affecting the integrity of the
adjacent space and equipment within that space.


if required in HAZID
In the same way than for gas dispersion analysis, a guidance shall be
developed for this kind of analysis

Bergen Viking conversion to LNG as
fuel
► Conversion to LNG includes generating
sets, complete LNG fuel supply and
bunker system/tanks, and automation
system for the LNG system.
► The vessel conversion will
encompass the removal of 4 diesel
generating sets and the
installation of 2 new natural gas
(NG) fuelled generating sets,
delivered from Bergen Engines AS.
The conversion includes also 2 off
150m3 LNG tanks. of IMO type C,
installed on open deck.
► Bergen Viking is a 95 meter long chemical and product tanker
operating along the long Norwegian coastline for Statoil and was
delivered in 2007.

The next frontier
EVERGAS gas carriers Dragon class, switch
from LNG as fuel to Liquid Ethane as fuel.
►The change from LNG to ethane does not
influence in general the design of the
components.
►The thermal design is different with less
required heat load dissipation due to less engine
consumption.
►All the system have been recalibrated for
ethane instead of LNG.
►Gas detector have been calibrated for correct
setting of %LEL according to ethane.

Conclusiones
•
•
El gas como fuel es una tecnología realista y madura
PERO
Es una elección que obliga a la respuesta y planteamiento en una etapa
temprana de aspectos tale como:
–
–
–
–
–
–
–
–
•
Rentabilidad
Tipo de tanque
Posición de los tanques
Posición de las ventilaciones (vent mast) y de la bunkering station
Segregación de espacios
Procedimientos
Entrenamiento
Duración de las operaciones de bunkering
No hay que olvidar nunca que el riesgo es inversamente proporcional al
conocimiento
