AIDAPrima

First cruise vessel in the world

equipped with a dual fuel main engine

and dual fuel auxiliary boiler to allow

the use of LNG as a fuel source when at

berth

– to generate electricity and

steam/hotwater,

– Gas consumption of the dual fuel

engine is supplied by onshore LNG

truck (no LNG tank onboard).

Regular 7-day-schedule calling

Hamburg, Le Havre, Southampton,

Zeebrugge and Rotterdam throughout

the entire year

Technical solution for LNG fuelling

Pressure Build Up as safe & simple transfer

system

7

Reliable, safe fuelling system

Reduction of possible sources of

release next to the vessel (less

flange connections compared to

a pump solution)

Fuel preparation room

Safety zone around the LNG

truck


Safety concept for LNG Fuelling of AIDAPrima

8

Extensive safety concept developed for

LNG fuelling operation (5 s for ESD)

Double walled hose including

monitoring system

LNG tank safety valves connected

with the vent system of the vessel

QCDC couplings and dry break away

coupling for fuelling hose and vent

line

Safety related valves are fail-safe-

close (in case of loss of electrical

energy supply (blackout), service air,

control signals)

Gas detection at the truck manifold

CCTV

Fire fighting equipment


Safety Analysis

Risk analysis for:

– Onboard system

– Transfer System

– Simultaneous operation

Quantitative Risk Assessment

for the different Ports

– Location specific risk

– Societal risk criteria

AIDA/Carnival Maritime

– Safety studies

– Permission management

states, flag)


Operator’s Experience

11

Original concept was a pumped solution

– Needed to be changed due to logistics and operational reasons

– Working closely with partners (Marine Services and DNV GL) developed

pressure build up system in short time

– Also required QRAs to be revalidated

Initial safety distances were too large to allow SIMOPS

– Double walled hose and reduced activation ESD solved this

Original supply partners dropped out in late 2015

– Required quick selection of new supplier and haulier

Approval process

– Not consistent despite all ports being in EU

– Different approval process required – complicated by truck to ship delivery

– Different risk acceptance criteria applied


Lessons Learnt

12

Choose partners – LNG supplier, Class, Flag, Ports, etc with care

– Ensure there is shared and common understanding of safety and

environmental objectives

– Be ready to help educate those that are not familiar with LNG

Leverage existing experience in this space.

Regular updates critical

– Make sure that everyone is kept well informed of status of project and critical

deliverable dates etc

Be prepared for setbacks and ready to intervene if necessary

Training, exercises and planning are critical

– Dry runs invaluable. What works on paper does not always work in practice

– Crew training on actual equipment essential, particularly interaction between

ship & truck operators

– Accidents will happen but can be mitigated by training and readiness to act

LNG as fuel is not the same as LNG as Cargo


The path to becoming ‘LNG Ready’

13

1. STRATEGY – FUEL DECISION

• High level technical feasibility

• Fuel consumption estimates

• Financial feasibility

• Cost, pay-back time and sensitivity analysis

• Fuel availability

2. CONCEPT CAPTURE

• Detailed technical feasibility study

• Performance benchmarking

(Machinery and tank evaluation and

optimization)

• Concept Design Review

(Statement - class acceptance)

• HAZID

CLASS APPROVAL (after vessel is ‘LNG Ready’

3. INITIAL DESIGN

• Approval in Principle

4. RISK ASSESSMENT

• Gas fuel safety risk assessment (mandatory

by IMO)

Decision Points. Proceed with the LNG option or not.
