Ship design concept to solve the zero-emission challenge

ULSTEIN THOR will feature a Thorium MSR to generate vast amounts of clean, safe electricity. Therefore, solve the zero-emission challenge.

Ulstein has launched ‘ULSTEIN THOR’, a 149m 3R (Replenishment, Research, and Rescue) design. It will feature a Thorium Molten Salt Reactor (MSR) to generate vast amounts of clean, safe electricity. Therefore, enabling the vessel to operate as a mobile power/charging station for a new breed of battery-driven cruise ships to solve the zero-emission challenge.

Concept

The vessel concept is capable of solving the challenge of zero-emission cruise operations a reality. Ulstein believes the concept, hereafter referred to as ‘Thor’, maybe the missing piece of the zero-emissions puzzle for a broad range of maritime and ocean industry applications. To demonstrate its feasibility, Ulstein has also developed the ULSTEIN SIF concept, a 100m long, 160 POB capacity, zero-emission expedition cruise ship. This Ice Class 1C vessel will run on next-generation batteries, utilizing ‘Thor’ to recharge while at sea.

Silver Bullet Discovery

“We have the goals, ambition, and environmental imperative to switch to zero-emission operations, but, until now, we haven’t had the solution,” “We believe ‘Thor’ might be the answer we’ve been looking for. ‘Thor’ is essentially a floating, multi-purpose ‘power station’ that will enable a new battery revolution.”

“Expedition cruise ships operate in increasingly remote, and environmentally fragile, areas. At the same time, the industry faces growing pressure from diverse stakeholders to preserve nature as it is and ban the environmental impact of cruising. ‘Thor’ enables replenishment of energy and supplies on site, while also boasting the technology to facilitate rescue operations, as well as conducting research tasks. It is, in effect, a crucial piece of infrastructure to support sustainable and safer operations. ‘Thor’ literally has the power to change our entire industry,”

The Energy to Transform

Moreover, thorium has been identified as having huge potential for a maritime industry hunting for clean alternative fuels.

Note that, MSRs are safe, efficient, and operationally proven solutions that work by dissolving Thorium – an abundant, naturally occurring metal with low radioactivity – in liquid salt. The ensuing chain reaction heats the salt, producing steam to drive a turbine and create electricity. Although developments on land are well documented, its potential for delivering clean maritime power has yet to be incorporated into a vessel design. Ulstein, famed for innovating the revolutionary X-BOW® design, has seen an opportunity to change that, potentially heralding a new dawn of clean power for cruise and maritime operations.

‘Thor’s’ charging capacity has been scaled to satisfy the power needs of four expedition cruise ships simultaneously. ‘Thor’ itself would never need to refuel. As such, ‘Thor’ is intended to provide a blueprint for entirely self-sufficient vessels of the future to solve the zero-emission challenge.

Generating Excitement

Speaking about the suitability of Thorium MSRs as an energy source for maritime applications; Jan Emblemsvåg, Professor at the Norwegian University of Science and Technology, advised as follows. Note that, he is an expert in the field of Thorium and nuclear power generation.

“MSRs have enormous potential for enabling clean shipping. There is so much uncertainty over future fuels, but here we have an abundant energy source that, with the right approach, can be safe, much more efficient, cheaper, with a smaller environmental footprint than any existing alternative. From my perspective, I see this as the most viable, and potentially the only credible, solution for a zero-emission fleet that can operate under commercial terms and cost levels. The ‘Thor’ concept is exactly the kind of innovation we need for sustainable success at sea.”

An Urgent Conversation

Both ‘Thor’ and ‘Sif’ feature Ulstein’s eye-catching X-BOW® design, created for greater operability, comfort, operational functionality, and fuel efficiency.

‘Thor’ features; helicopter pads, firefighting equipment, rescue booms, workboats, autonomous surface vehicles and airborne drones, cranes, laboratories, and a lecture lounge.

The expedition cruise vessel ‘Sif’ can accommodate up to 80 passengers and 80 crew. Thus, offering silent, zero-emission expedition cruises to remote areas, including Arctic and Antarctic waters.

“Here we have two concepts in one to showcase a cleaner, safer, and more sustainable way ahead for cruise ship owners and operators, not to mention maritime in general,”

Øyvind G. Kamsvåg, Chief Designer at Ulstein. ‘Thor’ and ‘Sif’ demonstrate what is possible when we approach challenges from a new direction.

“I’m excited to see where ‘Thor’ and ‘Sif’ can take us as we look to a zero-emissions horizon.”
