Wärtsilä solutions are to be used in retrofitting the world’s largest private residential ship to enable it to conform to ocean anti-pollution regulations.

The World will be retrofitted with a Wärtsilä Advanced Wastewater treatment system and a Wärtsilä Nacos Platinum system for navigation and external communication purposes, the company said.

The Wärtsilä Advanced Wastewater solution will replace an existing system and keep the vessel in full compliance with the International Maritime Organisation’s (IMO) requirements concerning the prevention of pollution from ships. The ship is owned by its residents and is managed by ROW Management Ltd based in Fort Lauderdale, Florida, USA. The equipment is scheduled for delivery in April, 2016.

Wärtsilä Hamworthy Membrane BioReactor (MBR) solutions are designed to facilitate the management and treatment of both ‘grey’ and ‘black’ wastewater, and to monitor discharges to the sea. The Wärtsilä system treats black and grey water so that the effluent can meet the most stringent marine discharge standards across the globe, including the latest nutrients removal requirements in the Baltic Sea, the company said.

The navigation retrofit to The World will replace an earlier system. “The new installation will ensure that the vessel has the latest and most technically advanced system available. The Wärtsilä Nacos Platinum system’s unique combination of integrated voyage planning, monitoring, and track control significantly reduces the workload for ship navigators, while improving navigational safety,” it said.

The system to be supplied as part of this order includes the unique integration of an ice radar. The World is powered by Wärtsilä main and auxiliary engines, namely two 12-cylinder and three 8-cylinder Wärtsilä 32 engines.

“We at Wärtsilä are committed to assisting marine industry operators to reduce their environmental impact and to increase their operational efficiency. These goals are being met with this contract. The MBR system being supplied for this very special vessel will enable it to comply with the very stringent regulations relating to wastewater discharge. Being a retrofit project, we had to design the system to fit the existing space. This created something of a design challenge, but our experience and know-how allowed us to meet the customer’s needs and provide an optimal solution. Similarly, the navigational system represents the very latest technology,” says Juha Kytölä, vice president, Environmental Solutions, Wärtsilä.

The World is a 196.35 m (644 ft) long vessel that features a concept combining a private yacht and a luxury vacation home. The ship comprises 165 individual ‘homes’ that are owned by the residents, who together own the ship. It sails the globe and caters to the highest standards of convenience and lifestyle.

The onboard systems, including that for wastewater treatment, are required to be of the highest possible quality.

Wärtsilä’s innovative MBR system is an evolution of the company’s proven sewage treatment technology for handling grey and black water waste. The technology is an advanced wastewater treatment process based on biological degradation and membrane separation. It is capable of meeting both current and anticipated effluent quality standards.

The Wärtsilä Nacos Platinum Integrated Automation Navigation Control System is a fully integrated system that provides outstanding features in terms of usability, scalability and network by means of a single common hardware and software platform.
