Offshore Construction in South Korea
LOCATION OF CONSTRUCTION TO LOCATION OF OPERATIONS
The Goal for 2011 onward; 6th generation Drill ships ready for operations in Brazil
The Goal only a few hundred years ago a 6th Generation Sail Ship to reach Brazil
Differences then and now:
• Same Goals
• Different technology
• Different dreams
• Different needs
Then it started out with Manual Labor
And more manual labor to build ships
Early 20th century the Mass Production
Only since the last 30 years: Little Manual Labor / Fully Automated cutting Machines.
Erection Block / Section
Pre Outfitting for Block Sections
Blasting & Painting & Coating
• Blasting will take in block stage in controlled environments (blast shops) with grid.
• Painting & Coating will take place in block stage will take place mainly in controlled environment.
• The Hull and Superstructure• The underwater part of the Hull• The Individual Tanks• The Equipment and it’s systems
The good old days
Block Construction / Use Sections
YARD Overall Project Plan Construction Facilities
• YARD will use 5 mayor location for construction of Block Sections & Modules
• Main yard: Majority of blocks and the Hull• Shin Han Yard: Living Quarters & Heli deck• Sung Jin: Certain curved blocks (bow & stern)• Posh: Mud module Roof sections• Hochang: Derrick and Flap & small sections

YARD reality to Planning
YARD overall construction facilities for pre outfitting and piping spools
• YARD will use over 70 different vendors and subcontractors to assist with the production and fabrication of spools and outfitting materials:
• The biggest contributors (and mostly mentioned in the office)
• HARVARD, DEOK SU, TAECHANG, GANA, SAM NOK.
• KANG RIM, SUNG IL, SAM KUN, SHIN WOO, SUNG WANG
Process Piping well fabricated and inspected and installed
Welding Accepted, installation rejected
Failed After re-inspection
INSPECTIONS as there are thousands of inspections these are being catagorized
• YARD Witness Inspections; Owner and Class are invited for the inspection.
• YARD Monitor Inspection; YARD will perform the inspection Owner and Class could witness
• OWNER Patrol Inspection: Owner will inform YARD that a visit will take to a fabrication shop and a random inspection will take place
DOCUMENTATION for INSPECTIONS
• YARD Witness Inspection Sheet: To receive at each witness inspection for owner, YARD and Class
• OFR sheet: Owner performs a patrol inspection and finds a discrepancy. Owner will issue to YARD
• YARD NCR: A failure occurred, YARD will issue a NCR
• OWNER NCR: In case an OFR will not be resolved within a certain time Owner will change to a NCR
• Class discrepancy: Class will issue to YARD
• In any case of failure or rejection these items will become “punch items”
WEB SITES for inspections planning & tracking of results and punchitems
• YARD has 2 websites available to track the inspections and the punch items
• PCS: This website is for all inspections on and off site, excluding paint inspections; Also for the Punch items.
• E-QISS: This website is for all inspections on and offsite, including paint inspections AND the NDE reports.

Daily Activities and Inspection reviews in the site office, with Korean Inspectors
Present status in site office
• Every morning: we review the websites to review the inspection planning and locations
• Every Morning: we have a pre inspection meeting with all inspectors to review the daily schedule
• Every end of the day: we have a short summary on inspections; failures and owner findings
• Every Friday afternoon: we have an evaluation QA/QC meeting with YARD, Owner and Class on the results and the next week look ahead
Present Status for Site Inspection Team
• For construction Owner has hired and will further hire local inspectors specialized in construction for drill ships in various disciplines.
• Additionally part of the Engineering team will slowly grow into the construction and mechanical completion of the construction phase.
• Following Mayor Disciplines:
• HSE (safety first!)• Hull, Structure & Welding • Piping & Mechanical & Installation• Painting & Coating• Later: Outfitting, Electrical, Marine, Drilling, Subsea.
• All the inspectors will be lead by the construction and QA/QC department and for each discipline the leader will get involved in the failures, corrections, improvements and changes.
Construction Phase, Block Stage
• Total amount of small, block is 238
• Total amount of erection block is 14
• Separate are the Accommodation Block, the mud module, The Funnel Casing, The Derrick, The BOP, and the Deck Cranes
Block Stage on yard
Funnel Casing; Weight approx 500mT Accommodation: Weight approx 1800mT
Hull Block stage Program
Block Stage; Big Blocks on the Slipway
Load Out (Horizontal Launching) of Complete Hull
Lifting on large blocks
Lifting of Mud module: Weight 1400mT And Lifting of the Drill tower (Derrick) Weight 1200mT.
THE NEXT PHASES
• The Construction Phase is normally completed with the launching of the vessel.
• Then the Mechanical Completion Phase will start
• Followed by the pre commissioning phase• The commissioning and the integration
commissioning phase• And finally the Sea Trials• Closing with the delivery.
A completed drill ship
Let’s try to avoid Shipwrecking
And let’s make sure we will avoid a Blow Out.
Make sure we will be ready for our Company and Client in Brazil in 2011 ONWARD
