A new hull design aims to lower resistance, total propulsion energy demand and CO2 production.
The design was developed as part of a project to lower the environmental footprint of a new LNG fuelled ro-pax ferry. Unveiled at the Power and Propulsion Alternatives for Ships conference organised by The Royal Institution of Naval Architects, the project is being led by HydroComp, Inc, in cooperation with Greek partners NAP Engineering, HeLeNGi Engineering and Blue Star Ferries.
During the project, new capabilities in HydroComp’s NavCad software were applied to predict resistance using its ADVM analytical method, allowing local hull form shape to be evaluated for its contribution on resistance.
This information was applied during design to reduce hull resistance by some 10% with appropriate modification of stern characteristics. The modified design with an alternate dual-fuel (MDO-LNG) engine ultimately achieved a 14% reduction in total propulsion energy demand and a 34% reduction in CO2 production.
Approval in principle
Donald MacPherson, technical director at HydroComp, said that the comprehensive design of the ship has already received “Approval-in-principle” from Lloyds Register.
When completed, the overall length of the ro-pax ferry will be 145m, will have a normal passenger capacity of 1400 and capacity of 1000 lane metres. The vessel will comply with SOLAS, Safe Return to Port and IGF Code Rules and Regulations.
This design work and analytical studies are included in the framework of the POSEIDON MED II programme, which promotes the use of LNG as marine fuel in the Eastern Mediterranean Region and is co-funded by the EU.
