50Te Vertical Lay System

The VLS-50Te is a portable vertical lay system for the deployment and retrieval of subsea umbilicals, risers and flowlines (SURF).

The innovation facilitates the transit of flexible products from on-deck carousels or reel drive systems to a vertical orientation so that they can be installed over the side or through the moon pool of a vessel.
