   Highly versatile modular
   3000 m work class
   vehicle for underwater
   intervention and survey

The Acergy Core Vehicle (ACV) is an advanced design of high
performance intervention ROV system capable of supporting
demanding SURF, IMR and survey operations.
The ACV has a powerful 150 SHP hydraulic system and thruster configuration. The vehicle is
fitted with a 7-function master/slave T4 manipulator and a 5-function Rigmaster grabber.

The vehicle provides the most efficient intervention support to projects. It is equipped with a
high level of structural interface points for external and internally mounted tooling packages.
It has ‘plug and play’ hydraulic and control services to facilitate quick tooling integration.

The vehicle is fitted with a subsea dynamic positioning system for enhanced control of the

The TMS unit can accommodate up to 1500 m of tether for long excursion operations and
can also be fitted with thrusters for enhanced position and orientation control.
