INNOVATIVE VESSELS’ DESIGNS Driving forces towards hull and onboard systems innovation: 1. Maximizing the economy of scale factor still plays a key role in “blue water”

marine segment. Due to fuel prices pressure however, innovation is constantly in need of bringing forth designs that will better balance the function of minimizing fuel by taking the maximum cargo space usage.

2. The “Green Ship” concept is particularly quite attractive in cruise sector, where passengers (or “guests” as is more marketing - correct) are critically investigating their ship regarding her environmental footprint and impact.

3. Linked to the above, a “green” cruise ship or ferry will be more suitable for sailing in sensitive waters, like the Artic or northern Canada.

4. Oil is in a transition phase due to emission reduction. Alternative fuels are foreseen, some of them displaying a very promising picture to ship-owners. LNG is one of them and already becomes a more mature alternative fuel. As barriers related to technology and infrastructure are removed, ship owners in all segments are looking to distinguish themselves through more sustainable and cleaner transportation by adopting it as marine fuel.

“One of the keys to establishing LNG as a standard for powering cruise ships is building out an extensive, safe and reliable infrastructure across the globe for this clean burning fossil fuel. We are proud to be on the forefront of advancing LNG as a fuel source for the cruise industry.” Tom Strang, Senior Vice President Carnival Corporation

OBJECTIVE “To develop a bulk carrier vessel which will comply with all known environmental regulations, current and forthcoming, with a highly competitive capex and opex. Mr. Alexandros Panagopulos, Chairman, Founder, Project Forward

• Forward Ships has applied existing and tested technology to design a cargo ship that emits up to 35% less CO2, 80% less NOx, 99% less Sox, 99% less PM than conventional ships

• Technology convergence, and Forward Ships’ clever approach, has enabled functionality which made our concept financially viable way, for the first time.

• Shell, one of our world-class partners in our project, calls Forward Ships a “Game-Changer” and is ready to accelerate the roll-out of LNG bunkering infrastructure for our launch in 2020.

INNOVATIVE

COMPACT

RO/PAX VESSEL

135 m

The very first COMPACT RO/PAX design in Greece adopting IGF (LNG as fuel) & “SAFE RETURN to PORT” SOLAS 2010 Rules Scope: to deliver the Detailed Design of a new breed of compact Ro/Pax ferry in such order so as to receive “Approval in Principle” by Lloyd’s Register. Scope of work has been initiated through the POSEIDON MED II Inputs, Optimization of ship's hull form, Final Design o Specific Owner’s (Blue Star Ferries) capacity requirements o Drag reduction: Resistance prediction and hull form improvements, especially in the stern area by taking into

account inputs from CP Manufacturer. o ADVM (Analytical Distributed Volume Method) applied at this design stage, resulting a 10% resistance

reduction o Operating profiles: Running on LNG as main fuel, including a special SRtP scenario. Main study route selected

is the Piraeus – Kastellorizo route via Dodekanissa. o CO₂ production: Due to dual-fueled engines and hull optimization, a total of 34% reduction of CO₂ emissions

is expected compared to similar sized vessel with conventional engines.

o Two TCS are foreseen.

Blue Star Ferries LNG Ro/Pax ferry: International acclaim The design was presented at the conference "Power and Propulsion Alternatives for Ships" organized by the internationally renowned British Organization "The Royal Institution of Naval Architects“, Rotterdam, November 2017

DESIGN-SIDE INNOVATION TO MINIMIZE THE ENVIRONMENTAL FOOTPRINT OF A RO/PAX FERRY D M MacPherson, HydroComp, Inc., USA I Bakas, NAP Engineering P.A., Greece

The EU co-funded POSEIDON MED II Deliverable 14.4, which initiated this work, calls for an LNG-fueled Ro/Pax ferry design, which included a mandate from the client (“Blue Star Ferries”, also a program partner) to investigate innovations focusing on the “footprint” of the vessel with regard to the ocean environment and fuel efficiency. The mandate was for innovations in both operation and design. This presentation will discuss the design-side investigations and their outcomes. New calculations proved vital to the success of the project, including use of a new computationally-efficient resistance prediction method that assists in the search for drag reduction from hull form changes, multi-mode duty profile optimization, and propulsion analysis prediction LNG and dual-fuel consumption indices. The presentation will also address new environment-focused analyses that were developed especially for this project, including reduction in the ship’s carbon footprint with full operational profile assessment of CO₂ emissions.

Greece:

1. Revithoussa LNG Terminal to incorporate Small Scale LNG Infrastructure

2. LNG Bunker Vessels Designs are already mature

3. Retrofit LNG Designs of existing vessels are under development

4. Experience is now gained in new built LNG ferry designs

Global (https://worldmaritimenews.com):

“Major shipping companies, who previously did not show great interest in LNG, are now starting to review their position. With the recent LNG bunker supply contracts we signed with Brittany Ferries and CMA CGM, we proved that we were both strongly supporting the use of LNG as a marine fuel and that we were able to provide dedicated logistics and tailor-made solutions to our customers.”

Olivier Jouny, Managing Director, Total Marine Fuels Global Solutions

“In February 2018, 122 LNG-fuelled marine ships were being built or sailing and 143 vessels were on order. That represents a very rapid growth considering that four years ago, in 2014, there were 56 LNG vessels, that’s less than 50 percent of actual numbers”.
