Sustainable Maritime Interiors - 2022 Report

71 Technology Several operators have implemented technologies that only work when needed. Stena Line says: “Utilising cameras and sensors, the fans on the Stena Scandinavica car deck operate more flexibly, shutting off when not needed. Less noise and less energy consumed!” TT-Line’s cabins are equipped with an energy saving unit. “It interrupts the power circuit for lights and switches the heating to eco-mode if the customer is not in the cabin.” Wasaline has “flexible use of passenger areas with intelligent ventilation and lighting” as well as smart cabins. Viking Line also uses dynamic ventilation and lighting to save energy. “Some spaces will be equipped with sensors. When these spaces are unused, the lights switch off automatically.” Similarly, the ventilation system is automatically turned off when spaces are not used for a while. A range of other technologies are deployed by Viking Line to improve the sustainability of processes onboard its ships. “Using a unique vacuum process, heat is converted into electricity on Viking Grace,” says the company, which points out: “We are the first passenger shipping company on the Baltic Sea to utilise digital cabin keys. Since early 2020, passengers on Viking XPRS can use the Viking Line app as the key to their cabin.” Wightlink has installed hybrid energy engines and a lift that “is capable of generating electricity through kinetic energy, warmth generated by the engine heats water on board and motion sensors are used to control LED lights in lesser-used areas.” Sun Ferry says: “Tinted glass panels are installed in passenger cabins of our fast ferries to reduce solar radiation with the room temperature lowered, resulting in less power consumption from air-conditioning.” Catering Ditching the plastic in kitchens and dining areas is an obvious move that many companies are making. Brittany Ferries says: “In our restaurants, stainless steel cutlery has replaced plastic, coffee stirrers are made of wood and straws are made of paper.” Rederij Doeksen says: “At our catering points, as many plastic cutlery and cups as possible have been replaced by metal cutlery and porcelain crockery. For our catering range, we choose as many products as possible with a UTZ quality mark.” Wightlink is also replacing “plastic cutlery, plates and straws with sustainably sourced alternatives”.
