AIDAPrima Gross tonnage: 125,000 tons Length overall: 300 m/ 984 ft Width: 37.6 m/ 121 ft No. of decks: 18 No. of staterooms: 1,643 (accommodating up to 3,286 passengers) Builder : Mitsubishi Heavy Industries ( Nagasaki, Japan) Delivered : March 2016 Class: DNVGL 5
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 6
Technical solution for LNG fuelling Pressure Build Up as safe & simple transfer system 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 7
Safety concept for LNG Fuelling of AIDAPrima 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-safeclose (in case of loss of electrical energy supply (blackout), service air, control signals) Gas detection at the truck manifold CCTV Fire fighting equipment 8
Safety Analysis Risk analysis for: Onboard system Transfer System Simultaneous operation Quantitative Risk Assessment for the different Ports 0.00 0.06 km Location specific risk Societal risk criteria Dispersion Analysis 9
First LNG Fuelling for Aida Prima in Hamburg on 7 th of May 2016 DNV GL contribution: Technical project management for AIDA/Carnival Maritime Safety studies Permission management with authorities (port states, flag) 10
Operator s Experience 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 11
Lessons Learnt 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 12
The path to becoming LNG Ready 2. CONCEPT CAPTURE Detailed technical feasibility study Performance benchmarking (Machinery and tank evaluation and optimization) Concept Design Review (Statement - class acceptance) HAZID 1. STRATEGY FUEL DECISION High level technical feasibility Fuel consumption estimates Financial feasibility Cost, pay-back time and sensitivity analysis Fuel availability 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. CLASS APPROVAL (after vessel is LNG Ready 13
