JUBILEE PHASE 1 PROJECT – Fabrication sites

JUBILEE PHASE 1 PROJECT
Key Subsea Development Challenges
1. Fast track development
2. FPSO located above a 2 km wide active
subsea canyon
3. Local fabrication of rigid jumpers
4. Ghana Emerging Oil and Gas Industry and
new country for Technip

JUBILEE PHASE 1 PROJECT – CHALLENGE #1 : FAST TRACK
FEED ongoing while progressing design (Client strategy)
• Split work in 3 packages progressed in parallel:
1. Flexible pipe design/ fabrication
2. Flexible pipe / controls systems installation and local logistics /
fabrication
3. Rigid pipe / jumper design, fabrication and installation
• Adjust project organization to accommodate changes
from FEED during design (matrix organisation)
• Take conservative assumptions to progress the design
and extensive use of interface system to control changes
• Collaborative working relationship with the Client

JUBILEE PHASE 1 PROJECT – CHALLENGE #1 : FAST TRACK
Rigid Pipe fabrication in
Germany – March 2009
PLETs Fabrication in
Technip Finland yard –
April 2009
Rigid pipe assembly in Technip spoolbases in USA and Angola – Nov. 2009
Pipe loading
December 2009
-
Pipe installation
January 2010

JUBILEE PHASE 1 PROJECT – CHALLENGE #2
FPSO on top of a 2 km wide active subsea canyon
• All flexible risers configured as pliant waves to avoid
canyon touchdown and provide lateral stability
• Significant quantity of buoyancy modules on each riser to
minimize loading on FPSO turret

JUBILEE PHASE 1 PROJECT – CHALLENGE #3
Local fabrication of rigid jumpers (1/4) - Ghana
• Suitable fabrication site with quay access for supply
vessel had to be set-up (no existing site)
• After evaluation of various sites, Sekondi naval base
was selected as the most suitable site
• Lease with Ghanaian
Navy signed in
September 2009
• Development of
appropriate HSE plan
designed for extensive
utilization of local
workforce

JUBILEE PHASE 1 PROJECT – CHALLENGE #3
Local fabrication of rigid jumpers (2/4)
• Jumper fabrication subcontractor
selected on past references and
local content plan
• Site preparation from September
2009 to January 2010

• No LTI for the entire duration of the work (450.000 manhours)
Jumper yard – 400,000 man-hours
without LTI Celebration

JUBILEE PHASE 1 PROJECT – CHALLENGE # 4
Ghana Emerging Oil & Gas Industry and
new country for Technip
• Early mobilisation of Country Manager in
Ghana to identify available services in
country and meet with local authorities
• Early visits by engineers to identify vessel
mobilisation sites and potential jumper
assembly yard
• Early definition, with Client support, of the
offshore personnel logistics
• Early audits of hotels in Takoradi area
• Early identification of offices for support
team in Ghana
