How to solve the challenge

■ In the late 80’s it was reported unstable performance of controlumbilicals and low reliability.

■ The challenges was typically related to:■ Leakages■ Damages■ Swage fittings■ etc



Steel Tube Umbilicals

The industry looked for analternative Controls Umbilical.

Aker Solutions developed aSteel Tube Umbilical designbased on a Flow-line Bundletechnology – somewhatdifferent to the traditional cabletechnology

Typically recognised by long lay-length PVC conduits

The combination of highstrength steel elements andlong lay-length gives a goodopportunity to utilize the axialcapacity.



Our steel tube umbilical concept

Deep Water Technology

■ Use of composite rods to enhanceaxial stiffness

■ Patented Aker Solutions design

■ Applicable in very deep waters,combination of deep waters, large tubeelements in dynamic configuration

■ Power Umbilicals

Umbilical Design

■ Aker Solutions design andmanufacturing process

■ Long lay-length

■ Tubes and cables encased bylongitudinal channel elements

■ Channel elements have radial contact– i.e. bridging



Long lay-length Shorter lay-length

■ Axial stiffness

■ Low twist

■ All elements in the same lay direction

■ Centre tube and helix tubes same strain


Ƭ

■ More twist and torsional unbalance

■ More unbalance in strain and stresses


Long lay-length Shorter lay-length

■ Axial stiffness

■ Low twist

■ All elements in the same lay direction

■ Centre tube and helix tubes same strain


■ More twist and torsional unbalance

■ More unbalance in strain and stresses

Ƭ


Additional benefits from the Profiles

■ High crush capacity

■ Test 1000 kN/m

■ Installation in deep waters



USAPUmbilical Stress Analysis Program


Temperature impact

Stress control

Reeling with large Centre Tubes

■ Finite element approach

■ All linear and non linear effects

■ Program focus on longitudinal helixbehaviour

■ Bell-mouth and bend stiffenermodelling

■ Full Catenary model

■ Actual material stiffness properties

Same Technology - Power Umbilicals


Long Step-outs

■ Manufacturing locations■ Moss – Norway■ Mobile – US Alabama

■ Carousel capacity■ High capacity both sites■ High flexibility with

■ Portable carousels■ Barges



Long Step-outs

Challenges:


■ Installation vessel carousel capacity■ Weather window – safe operation■ Damages – Spare/Repair

philosophy

■ Installation vessel carouselcapacity

■ Weather window■ Transport


Long Step-outs

■ Opportunities with Inline-connector■ Based on UTH technology for subsea pull-in and connection■ Short deck operation for connection■ Quick test method
