Innovative deliveries for more sustainable operations.

Taking bold commercial risks on novel vessel concepts with a strong focus on sustainability has made Olympic a pioneering player in the offshore energy sector. Its latest investment in a pair of new-build Construction Service Operation Vessels (CSOVs) based on Ulstein Group’s innovative TWIN X-STERN® solution has paid off, with close to 50% reductions in fuel consumption and emissions to boost environmental performance.

The Offshore Oil & Gas (OO&G) sector is experiencing a resurgence, driven by stable oil prices and a focus on efficiency and sustainability. This recovery has led to robust cash flows and new investments, especially in upstream activities, presenting an opportunity to integrate environmentally friendly practices.

The Olympic Zeus, launched in 2009, introduced a hybrid power system, reducing fuel consumption by up to 70%. After reaching its 15th anniversary in 2024, it continues to set new fuel efficiency and environmental performance standards.

With over a century of history, Ulstein Group prides itself on its dedicated ship designers who are integral to the company. United by a mission of innovation, they strive to challenge conventional wisdom and develop new solutions that enhance customer value.

"Do you need to adjust your vessel for a new charter? Maybe add a mezzanine deck, calculate the deck strength or stability characteristics for a new crane? We are here to assist you," states project manager aftermarket, Roy Lindset, at Ulstein Design & Solutions AS.

Aptly nicknamed ‘A 4-wheel-drive for the seas’, the ULSTEIN TWIN X-STERN is celebrated for its exceptional manoeuvrability. To date, this innovative feature has been incorporated into ten newbuilds, all designed for the walk-to-work market and measuring up to 90m in length. The next likely segments to adopt the TWIN X-STERN are subsea and cable-laying. 

As offshore wind farms grow in size and number of turbines, the demand for the capacity of existing inter-array cable laying vessels (CLVs) intensifies. The next-generation CLV must be capable, cost-effective, and able to serve more and larger turbines. 

Since unveiling the Thorium-powered ULSTEIN THOR design in April 2022, we have been swept by a wave of interest in the concept vessel and its unparalleled potential and capabilities. Set in a polar cruise context, ULSTEIN THOR alone could generate over 50 GWh of energy in a single 150-day cruise campaign. The result would be a significant environmental impact in Antarctica, with over 32,000 tonnes of CO2 emissions prevented.

The expected global gap in vessel capacity for foundation installation and transportation for ever-growing offshore wind components can slow down the growth speed of offshore wind farm developments across the globe. 

We accept the design challenge.

In the vast expanse of offshore wind energy, cable-laying vessels are essential—the silent architects of our renewable future. As wind farms grow larger and more ambitious, the demand for efficient cable installations has intensified. Enter the ULSTEIN SX225, a vessel designed to tackle the challenges head-on.

The offshore energy market is booming, and so is the demand for subsea vessels that can operate in challenging environments and perform complex tasks. Whether installing, maintaining, or decommissioning offshore wind farms or oil and gas platforms, subsea vessels need to be flexible, efficient, and reliable.

The offshore vessel market is experiencing a surge of optimism thanks to high growth rates and the highest-ever backlog of major subsea EPC (Engineering, Procurement, and Construction) contractors. 

From the Caribbean to the Antarctic, from the lab to the ship, the service engineers at Ulstein Power & Control face new challenges and opportunities every day. Their main tasks are to offer the best service and support for the control and power systems on board ships.

2023 marked a year of diverse achievements for Ulstein – from the drawing board to the open seas, delivering state-of-the-art vessels that embody our expertise and dedication.
