UMSIRE - JIP
Umbilical Termination Size Reduction
12th June 2012

The problem
Why UMSIRE?
One trend that has emerged in recent years in the design of umbilical systems is the progressive increase of the size and weight of end terminations
Driven by the need to integrate functions normally found on manifolds, this emerging trend poses extremely severe challenges to installers and appears to be compounded by the differing requirements of parties in the supply chain (FEED contractors, termination designers, operators and manufacturers)

The consequences
Why UMSIRE?
COST Oversize terminations often require
a bespoke solution leading to “re-inventing the wheel” syndrome
Carousels may have to be deployed instead of reels
TIME Increase in lead time Longer fabrication and assembly Increase in vessel time Installation vessel availability
RISK Together with terminations, bend
stiffeners and bend restrictors have grown in size and weight
Lack of clear definition of acceptable level of risk resulting in over-engineering
UTAs are not properly designed for lifting and over-boarding
RELIABILITY Long term reliability of the
umbilical system can be jeopardised

The solution
Why UMSIRE?
Following an Umbilical Manufacturers’ Federation initiative, several major umbilical installation contractors (Acergy, Saipem, Subsea7 andTechnip) and OTM Consulting collaborated towards the launch of a JIP for the development of a RP
The document would address the need to standardise the shape of umbilical terminations and identify guidelines for their size and weight
UMSIRE JIP objective: to reduce the size of umbilical terminations through increased understanding of the key issues associated to their design, manufacturing and installation and the development of a RP
