Mudline Equipment

Mudline Equipment transfers string weight off of the drilling vessel and onto the seabed. This also allows for disconnect and tiebacks when pre-drilling.  

VetcoGray offers a simple stack down system that is easy to use and reliable as well as Tree on Mudline (TOM) solutions designed to be installed in predominantly shallow water up to 90m. The Horizontal and Conventional Tree on Mudline systems can be configured for Diver or ROV installation and intervention activities.
