Product Datasheet

50Te VerticalLay 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.
