Topsides Umbilical Termination Assembly

TUTA (Topsides Umbilical Termination Assembly) is located on an offshore platform (topsides) and is the interface between the subsea umbilical and the platform fluid handling facilities (such as HPU’s and chemical injection pumps) and electrical controls. The TUTA is a network of piping, valves, gauges and instruments that directs the flow of chemicals (such as methanol) and hydraulic power fluid to and from the subsea umbilical. It may also incorporate electrical junction boxes for electrical power and communication cables. (Another term for this piece of equipment is UTB – Umbilical Termination Box).
