Technology group Wärtsilä is to supply and install an auto gasification system on board Princess Cruises’ ‘Regal Princess’.
This technology will enable the safe disposal of waste from the ship through a self-fuelling thermal de-composition unit, thereby significantly reducing greenhouse gas emissions. It will also lessen the requirement to offload waste at shore facilities.
The order was placed with Wärtsilä in July, 2019 and the equipment is scheduled for delivery in January, next year.
The gasification unit will replace one of the vessel’s on board incinerators, and will safely dispose of hazardous, contaminated, and dry burnable waste in an environmentally sustainable way, the company said.
The emissions quality from this system exceed the standards of land-based thermal destruction, and treating waste on board the vessel rather than offloading in port therefore significantly reduces the environmental impact.
Furthermore, since the system recovers energy from the waste heat being produced by the thermal destruction process, additional energy and emission savings will be gained. The auto gasification process will reduce the ship’s waste to less than 5% of the original volume, and will produce Bio Char, a sterilised inert material, and syngas (synthesis gas), which is recycled within the unit as fuel.
“Wärtsilä and Carnival have co-operated closely on numerous projects over the years, and we have delivered a number of advanced waste treatment systems for their vessels. Our experience with the auto gasification technology will help support them in their focus on efficiency and environmental sustainability,” said Jason Hardy, Head of Sales, Advanced Waste Management (Retrofit), Wärtsilä Marine.
Princess Cruises has made it clear that efficient waste management and reducing emissions are extremely important for the company, and for all Carnival Corp’s brands.
