Back to All

Like all Seajacks vessels, Seajacks Leviathan has been designed with a flexible deck space which means working in either the Oil & Gas or Offshore Wind industries is possible.

This state-of-the-art, self-propelled jack-up vessel operates in compliance with the most stringent regulations and in accordance with standard procedures required to operate in the North Sea hydrocarbon industry.


Leviathan will shortly be fitted with additional living quarters, increasing its maximum persons on board to 140! The vessel is already equipped with DP2 capability which allows for fast, safe and cost-efficient transit and positioning between locations; this not only transforms operations in the oil and gas industry, but also facilitates efficient installation and maintenance of offshore wind farms.

Leviathan’s reputation is as renowned as its sister vessel Kraken’s, with Leviathan completing work with Fluor on the Greater Gabbard Offshore Wind Farm. It has also worked with Zaratan on the Meerwind Offshore Wind Park installing the transition pieces and turbines of 88 Siemens 3.6MW wind turbines.
