This extended presentation discusses the integration aspect of new alternative technologies to either existing ships or how it should be considered in a new build where the expected lifetime of the ship is 20-30 years and where it may be necessary to do a midlife upgrade to next generation of alternative technologies The participants are Foreship, a highly respected, ship design and engineering company which has developed an unrivalled breadth of services since its formation in 2002 and their customer Carnival Maritime who will bring the perspective and strategy of a ship owner. Following the presentation of the perspectives the presenters will open the floor to questions and discussion.
