What happens when shipowners, naval architects and engineers team up to boost an already successful SOV vessel to make her the optimum choice for flexible operations? You get Windea Leibniz 2.0.

The offshore wind industry faces significant installation challenges with the increasing size of monopile foundations. With the patent-pending ULSTEIN U-STERN, we are introducing a safer, smarter and more competitive ship design solution for transporting, upending and installing large monopiles on DP.

Singapore-headquartered Cyan Renewables has contracted Ulstein Design & Solutions BV as the designer of a series of new floating foundation installation vessels (FFIV) dedicated to offshore wind. With an increasing lack of heavy lift installation vessels, these new FFIVs are needed to fill the gap.

VOC capture and utilization during loading of crude oil tankers is an important contribution to decarbonisation of shipping. Vaholmen has the solution for avoiding between 60-80% of the emissions during loading operation at offshore terminals, bringing the hydrocarbons back into the loop and realising its values.

Ulstein’s announcement of a Thorium-powered ship created massive interest in the market. As shipbuilders and designers, we are looking to take this concept from the drawing board to the deep blue sea. Is this the solution that industry, and society, have been searching for to enable a truly sustainable maritime future?

The energy transition is on. The shipping industry is working to reduce carbon footprint, or even better, to reach zero emission. Several new energy sources are evaluated, such as LNG, methanol, ammonia, hydrogen, biofuels and batteries. As a shipowner, you know you must act. But which fuel type is the right choice?

Ulstein has developed a ship with two sterns and main propeller units in each corner, ideally for offshore operations requiring continuous positioning. “The TWIN X-STERN is extremely manoeuvrable, comfortable to be on board and very environmentally friendly,” says Øyvind Gjerde Kamsvåg, Chief Designer at Ulstein.

Following the introduction of our first hydrogen fuelled, zero emission design in 2019, we now reveal our vision towards a marine hydrogen future. Where the ULSTEIN SX190 showcased that zero emission ships can be realised with today’s off-the-shelf technology, we now map the way to a hydrogen fuelled marine industry.

The urgent push for more renewable energy production to achieve climate goals translates into many new offshore wind projects. Simultaneously, ambitious climate goals also call for vessels to be developed with solutions for zero-emission operations.

In order to comply with regulations, as well as to minimise environmental impact, cruise operators will need new technical solutions. The ULSTEIN ZED power system allows cruise operators to visit vulnerable and protected areas without greenhouse gas emissions and local pollution.

Ulstein has ship solutions for all phases in the life of offshore wind farms. One of these is the foundation installation vessel 'Seaway Alfa Lift'. Custom-designed by Ulstein, she will serve the early development stage of new offshore wind farms, starting with the Dogger Bank Wind Farm.

In cooperation with shipowner Bernhard Schulte, Ulstein Design & Solutions has designed a diesel-electric propulsion system assisted by batteries to reduce operating hours on the main engines, save fuel and reduce environmental footprint. The hybrid system has been installed on the WINDEA JULES VERNE at Ulstein Verft.
