Cruise & Ferry Review - Spring/Summer 2022

Ship designers are uniquely placed to shape the environmental credentials of vessels. “When designing passenger ships, we have to focus on more aspects than when designing other vessel types,” says Finn Wollesen, managing director of Knud E. Hansen. “This includes flexible use and energy optimisation of hotel facilities, plus protection against viruses and diseases. Lightweight designs reduce emissions during operation as well as production-related emissions before the ship leaves the dock for the first time.” Virus control and flexible use are two aspects that have been implemented on the company’s concept design of the 150-metre Phoenix World Village Expedition Cruise vessel. Designers working on the interior aspects of the ship increasingly cooperate with the ship design teams on sustainability from the start of a project. “We embrace our influential role in this ecosystem and the responsibility we have as designers,” says Bente Medelbye Hansen, design director at Steen Friis Design. “To help assist shipowners make conscientious choices for their vessels’ interiors, we have developed The Sustainable Design Strategy. For every item specified, cradle-to-gate calculation of each chosen material or item can be provided. With this approach, we can calculate and evaluate the carbon dioxide emissions of the accommodation, which enables us to make a documented difference by selecting the least harmful materials available on the market.” Providers of new technologies for passenger ships are exploring new frontiers in the quest for lower emissions and greater efficiency. Independent consultant Foreship advises major cruise operators on the role of zero-emission fuel cells in ship propulsion. Its work includes analysis of a 77,000gt reference ship, evaluating the potential and limitations of polymer electrolyte membrane fuel cells (PEMFCs) and fast-emerging solid oxide fuel cell (SOFCs). “The study shows fuel cells achieving electrical efficiency nine to 11 per cent greater than internal combustion engines,” says the company. “It also establishes the LNG+SOFC solution as two per cent more electrically efficient than PEMFC solutions.” By providing software, services and data analysis, maritime software, services and data analysis company NAPA enables the industry to harness data to design and operate the efficient, safe, and sustainable ships of the future. “NAPA Voyage Optimization is an intelligent voyage planning tool which calculates optimal routes and speed profiles from a number of variables ranging from weather conditions to the specific operational needs of vessels,” says Mikko Kuosa, CEO of the company. “NAPA’s stability solution ensures the safe and optimal planning of stowage, cargo and ballast to optimise the ship’s trim and reduce fuel consumption.” The company’s 3D models improve its capability to design more efficient ships and safely include innovative clean technologies, such as wind propulsion systems.
