1. A feeder vessel for onshore-to-offshore transport of at least one elongate object,
the feeder vessel having a motion compensating carrier assembly supported on the hull, said carrier assembly having:
one motion compensated platform, configured for receiving and retaining thereon an elongate object, the platform comprising a top surface and a motion compensation mechanism connecting the one motion compensated platform to the hull and configured to provide compensating movements of the platform with respect to the hull,
said motion compensation mechanism comprising:
multiple extendable carrier actuators, each configured to extend and shorten along a respective longitudinal axis thereof, each connected at a respective first longitudinal end thereof via a respective first pivotal coupling to the hull and at a respective second longitudinal end via a second pivotal coupling to the platform; and
one or more carrier winches, each carrier winch configured for driving a carrier cable of which a cable segment extends from the respective carrier winch to the platform, such that traction by the respective carrier winch counteracts an extension of at least one of the carrier actuators,
wherein the multiple extendable carrier actuators are embodied as passive motion compensators to provide passive compensating movements of the platform, and
wherein the one or more carrier winches are embodied as active motion compensation winches to provide active compensating movements of the platform.
