Abstract
A system, apparatus, and method for transferring a subsea payload (such as seismic nodes) at a subsea position by using an elevator system located on a subsea basket. A plurality of seismic nodes may be located on a plurality of support slides, trays, or other node holders at different levels within the basket. The elevator system is configured to move the seismic nodes between different heights within the basket for external transfer from one or more vertical positions. During transfer operations between a subsea basket and an underwater vehicle (e.g., ROV), the desired level of seismic nodes may be positioned to the desired vertical position within the basket and transferred to the ROV by various transfer mechanisms, such as an extendable stinger or chain drive. Multiple levels of seismic nodes (or node holders) may be transferred between the basket and ROV during a single subsea docking.
