Argeo is a complete subsea service provider operating in three major verticals: oil & gas, marine minerals, and the renewables sector. SEAONICS recently completed the re-commissioning of a 50-ton Active Heave Compensated (AHC) subsea crane on their vessel, Argeo Venture. This achievement was made possible through a collaborative effort involving Fjellstrand Yard, Argeo, and SEAONICS specialists on-site.

“The upgrade of the Argeo Venture marks a significant advancement in our vessel's capabilities within the offshore energy sector. The addition of the crane strengthens our operational reach and efficiency, reinforcing our commitment to delivering exceptional value to our clients," says Trond F. Crantz, CEO of Argeo.
