Challenge I: Ultra Deep Water

■ Running time ■ Decreased running time =

Decreased cost

■ Weight ■ Welding limits selection of high

strength steel

■ Increased yield strength in riser

Decrease weight requirement

■ Make and break ■ Multiple make and break will

facilitate ease of well jumping

■ Monitoring ■ Fatigue and utilization are based

upon theoretical analysis/estimate

■ Increased monitoring will reduce

conservatism

■ Wear and tear ■ Use of “slips” will induce damage

to riser pipe

Challenge II: Sour Service

■ Material resistance ■ Limits selection of material if welds are present (typically >75-80KSI yield) for a

robust serial production

■ Forging material have limitations >80-85KSI yield for a robust serial production

Challenge III: High Fatigue

■ Stress Concentration Factor (SCF) ■ Ultra deep water gives highly

loaded risers, and an optimized

load distribution will define the

fatigue capacity

■ Predictable SCF during the

lifetime is a key design feature for

increased lifetime

■ Weld ■ Difficult to quantify internal weld

root quality and corresponding

actual SCF

■ Complicated NDT (reliability)

■ Challenging recertification

■ Monitoring ■ Real time monitoring in

collaboration with predictable SCF

will increase operational safety

■ Essential for control of remaining

fatigue life

Challenge IV: Arctic Environments

■ Handling ■ Automated make and break will

reduce human presence at drill

floor in harsh environments

■ HSE aspect covered by

automation

■ Material properties ■ Fracture toughness is dependent

on temperature

■ Operation of risers will be

dependent on use of material with

greater toughness (charpy values)

and yield properties

Upset Technology

MCE Deepwater Development 2014

©Tenaris 2012

■ Upsetting of pipe is a robust and

repetitive steel making process

that enables the use of higher

strength material

■ No heat affected zones which

reduces ductility, sour service

performance, fatigue life and

material imperfections

Optimised Grooves

MCE Deepwater Development 2014

Threads

Optimised load

grooves

Design principles:

■ Connector designed to be

stronger than pipe

■ Preloaded within normal

operation

■ Force distribution optimized

■ Designed for low SCF

(no small radiuses or sharp

corners in load path)

■ Improved Sour Service

performance

Hang-Off in Spider

MCE Deepwater Development 2014

Slips

Spider

■ Slips are simple and quick to use.

They are based on friction and

contribute to riser damage and

higher dynamic loadings to the

riser

■ These effects increase with water

depth as the riser system

becomes heavier

■ Spider based hang off uses

dedicated load bearing surfaces

and eliminates riser damage

Remotely Operated Connector Make Up Tool

MCE Deepwater Development 2014

■ Historically most work on drill

floor was manual

■ Today new build rigs are equipped

with remotely operated equipment

for all pipe and riser handling

operations

■ Utilising these tools significantly

improves HSE and accelerates run

time in deepwater

■ This is also achievable for

workover risers
