Sustainability PERformance of LNG-based maritime mobility (SUPER-LNG)• Environmental pressure in port areas is high and Liquefied
Natural Gas is proposed as a low-carbon clean fuel for marinetransport in port areas.
• Distribution networks and port infrastructures for the bunkeringof LNG-powered ships requires technologies and solutionsassuring a high level of safety in touristic areas of the Adriaticand Ionian sea. The project aims at providing a uniformframework to support the implementation of technical systemsfor the distribution and supply of LNG in port areas.

Distribution of literature in 2008-2018 RESEARCH AREAS• LNG bunkering operations (7 docs)
• Small scale LNG facilities (2 docs)
• LNG at ports combined with the supply network (2 docs)
• Consequence assessment of LNG releases at ports (3 docs)
• Risk assessment for LNG storage and bunkering at ports (5 docs)
Identified Gaps
9
• Lack of harmonization of LNG safety regulations both at sea and on the land, for all LNG operations at ports namely, ship-fuelling, bunkering and LNG land facilities
• Lack of harmonization for LNG safety regulations within various countries across the world
• Lack of knowledge for estimating safety and hazardous zones during storage and bunkering of LNG, under various conditions

MAJOR STEPS FOR QRA
13
➢Decomposition of port in areas where HAZOP orMLD may be applied
➢Areas of the port
• Hose-loading arm• Ship receiving LNG• Buffer ship• Storage tanks
14
HAZARD IDENTIFICATION IN PORTS HANDLING LNG
INITIATING EVENTS IN A PORT HANDLING LNG
✓ LNG storage tank
• Boiloff removal malfunction, during unloading or storage
• Excess external heat in storage tank area
• Level rise beyond safety height, or overfilling
• Continuation of unloading beyond lower safety level
15
✓ Loading arm section
• Excess external heat in jetty area
• Water hammer in loading arm, due to inadvertent valve closure
• Inadequate cooling of loading arm
• High winds during loading-unloading
✓ Truck
• Excess external heat
• Level rise beyond safety height
• Extra load on hose
SAFETY SYSTEMS
16
SAFETY SYSTEMS FOR INITIATING EVENT:Level rise beyond safety limit
➢Manual stop of Loading
➢Emergency Shutdown System (ESD)
➢Pressure Safety Valves (PSV)
Damage states
17
LNG Storage Tank• Tank rupture owing to overpressure, overfilling
Loading arm- Unloading section• Pipe rupture• Hose rupture
Truck• Truck rupture
Buffer Ship• Buffer ship rupture

Consequence assessment means to evaluate the spatial and temporaldistribution of:
Pressure and impulse after explosion Heat radiation after fire Fragments after explosion Concentration if no ignition (dispersion analysis)
Environmental pollution is not taken into account (non-acute accident)
