LNG on Cruise Vessels

Cruise Liner driven by LNG: Operational Experience Dr.-Ing. Christoph Schladör, Director Technical Projects Hamburg, October 29, 2019 Introduction • 70 years of history • Market leader in Germany • 4 cruise ships with unique • 10 cruise ships in operation • 13 cruise ships in operation Italian flavor 2 Introduction AIDA Cruises Sustainability Journey 3 Introduction Agenda • AIDA’s path to LNG • Design of AIDAnova – LNG-Technology • Preparation work for LNG-Operation – Procedures and Trainings • Bunker procedure • Improvements and Lessons Learned 4 AIDA’s path to LNG Pioneering in shipping • 2015: AIDAsol as first Cruise Ship to be supplied with electricity from an LNG powered hybrid barge • 2016: AIDAprima’s dual fuel generator using LNG to supply all hotel load whilst alongside in Northern Europe • 2017: AIDAperla using LNG in port in the Western Mediterranean Sea 5 AIDA’s path to LNG AIDAnova (Helios I) – First Cruise Vessel on 100 % LNG Operation • Builder: Meyer Werft Papenburg Main data • Order date: June 14, 2015 (IGF Code adopted June 11, 2015) Length 337 m Tonnage 184 000 GT • Delivery: December 2018 Service speed 17 kn Number of cabins 2 626 Max. passengers 6 654 Installed power 61 760 kW Propulsion 37 MW Sister vessels on order XL I - Costa Smeralda Nov. 2019 Helios II May 2021 XL II Spring 2021 Helios III 2023 plus six ships for CCL and CUK 6 Design of AIDAnova - LNG-Technology AIDAnova (Helios I) – First Cruise Vessel on 100 % LNG Operation • 4x 16 Cylinder 46DF gensets by Caterpillar/MaK • 3600 m3 LNG in three Type ‘C’ Tanks • Operating at 0.7 bar, max. pressure 4.5 bar • LNG capacity for > 14 days • “Safe Return to Port” with MGO (2200 m3) 7 Design of AIDAnova - LNG-Technology Why choose LNG? 8 Design of AIDAnova - LNG-Technology Why choose LNG? • Best emission profile of any fossil fuel. LNG is the only fuel that meets all emissions rules post 2020 without abatement or additional equipment • No waste residue • IGF code provides regulatory certainty • Aligns with AIDA’s sustainability commitments >95% reduction in particulate Substantial well to wake reduction in matter carbon emissions Zero sulfur dioxide emissions Significant reduction in nitrogen oxides 9 Procedures and Trainings Procedure Development for LNG operation • Creation of a ‘LNG working group’ within Carnival Corporation – including ship and shore representatives from all brands • Main tasks of the working group – Analyze the LNG system and include all new operational requirements to the HESS-MS – make sure that a LNG Safety culture is implemented into the HESS-MS – Review existing standards and adjust to include LNG related matters, covering Technical, Health and Safety, Emergency Response, Environmental, Hotel, Security and Training More than 100 procedures reviewed and adjusted. 10 Procedures and Trainings Training Requirements for LNG operation • Identify the new LNG specific tasks on board of the Helios/XL ships (operation and maintenance) • Specific training for Compliance (STCW + Seatime) and Competence (Procedures and Technology) per function on board • Develop concept to assist LNG operation: ship and shore organization (LNG Engineer / LNG SME) 11 Procedures and Trainings Training Requirements for LNG operation 12 Procedures and Trainings Training Requirements for LNG operation 13 Bunker procedure and timelines AIDAnova – 1st LNG Bunkering via “Cardissa” in Tenerife Dec 18, 2018 14 Bunker procedure and timelines AIDAnova – 3rd LNG Bunkering via “Coral Methane” in Tenerife Jan 15, 2019 15 Bunker procedure and timelines AIDAnova – 3rd LNG Bunkering via “Coral Methane” in Tenerife 16 Bunker procedure and timelines 1400 16:00 14:00 1200 12:00 1000 10:00 800 delivered 08:00 time 600 tons 06:00 400 04:00 metric 02:00 200 00:00 0 25-Nov18-Dez 01-Jan 15-Jan 29-Jan 12-Feb 26-Feb 12-Mrz 26-Mrz 09-Apr 25-Apr 02-Mai 16-Mai 30-Mai 13-Jun 27-Jun Unmooring Documentation Disconnection Purging Transfer Ramp Up Cool down Testing Connection Mooring Delivered (MT) Bunker time total 15 hours at ship‘s delivery. Improvement to 9 hours (normalized on 1100 mt per call) 17 Improvements and Lessons Learned LNG System Measured Results week 2019/42 Ship’s MGO speed Improvements and Lessons Learned Conclusion of nine months LNG operation • Technical concept is working well • Minor technical modification needed – 97 % of energy provided from LNG – Improve bunker station layout • Procedures require improvements – Improve hose connection process – Workload on crew is high – Better systematic approach required • Don’t reinvent the wheel! Use good partners LNG operation on a Cruise Ship is a success! AIDAnova has AIDAnova has bunkered bunkered LNG in mt around 19 000 mt 3 different ports 3 21 000 of LNG since delivery 24 of 74 of cruise 10 LNG Fuelled ships on order Ships on order for delivery by 2026 for Carnival 10 24 will use LNG 19 Improvements and Lessons Learned https://en.nabu.de/news/2019/26855.html 20 Thank you very much! 21.
