UMSIRE - JIP Umbilical Termination Size Reduction 12 th June 2012 1

2. 2 Source: Subsea7 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) 2000 2012

3. 3 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

4. 4 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

5. 5 UMSIRE - timeline Apr 2011 Sep 2011 June 2012 Sept 2010 A scoping meeting was held with the installers to agree on the outline of the JIP UMSIRE JIP Launch meeting took place. 15 companies attended UMSIRE JIP Kick off meeting Meetings held regularly every 3 months (September 2012 meeting taking place in Houston)
