Product Definition

Frames Topside Umbilical Termination Units (TUTUs) provide a

reliable and robust interface between the main umbilical and the

topside utility equipment on a platform or a FPSO. The units can

be used for hydraulic fluids such as water/glycol or mineral oil,

electric signals, fiber-optic communication, but also for a wide

range of chemical fluids.

Product Description

At Frames, we work closely with your business to develop customized

solutions that match your unique process conditions, plot space and

other site-specific requirements. We generally design our Topside

Umbilical Termination Units as an AISI316L enclosure or an AISI316L

open frame, which may be in accordance with design standard DNV

2.7.1 or DNV 2.7.3 for portable offshore units. The TUTUs can also

be designed to include nozzle loads and blast loads to allow the units

to operate in harsh environments.

A typical Frames Topside Umbilical Termination

Unit comprises single or double block-and-

bleed isolation valves, pressure gauges and

junction boxes for power, signal and fiber-optic

communications. Moreover, the units can be

supplied in various exotic materials, such as

Incoloy 825, 6Mo, Super Duplex and Hastelloy

C276. If required, the units can also be supplied

with double-ferrule cone-and-thread fittings

and/or piping in various materials, sizes and

pressure classes.

Junction boxes for both electrical and fiber-optic

communication are generally supplied in AISI316L

material and certified for use in a hazardous area

as per applicable international standards such as

IECEx, ATEX, Inmetro, and CSA.Topside Umbilical Termination Unit

Topside Umbilical Termination Unit (TUTU)


Process Description

A Frames Topside Umbilical Termination Unit is designed for safe

bleeding off of hydraulic or chemical fluids in order to de-energize

the pressure in the umbilical line. The units can also be used for

pressure monitoring.

A TUTU will typically be connected to a subsea HPU, a production

HPU and/or a chemical injection skid. The TUTU lines will be sized

for the applicable fluid and pressure levels, flow requirements and

compatibility with the process fluid. The lines can be designed with

inlet and/or outlet pressure monitoring by means of a pressure

gauge, pressure switch or a pressure transmitter.

The single or double block-and-bleed valves can be sized with a

Ball-Ball-Ball or Ball-Needle-Ball or Needle-Needle-Needle valves or

manifolds, depending on the required flow or fluid condition.
