Dear Tolga,

You are talking "DANGER" here.
Mark my word. My first suggestion: "Hire a Qualified person (with past oxygen experience)"
When Tranportation of Oxygen is involved, you need extra care in design, you need a person with past oxygen experience, and if you dont have company design guide line you need standard design specification from well known engineering companies.
I know it because, In my last job, i created a Piping design guide line for Oxygen service. (First compiling all well known engineering company standards (like SHELL, BP etc) and then having 10 to 20 meetings with all concerned engineer to discuss issues etc)

I dont want to give any simple answer to your query. Cause there is no simple answer. If i had to answer, it will be in 20 pages.

However, these are the codes/standards help you in the process. 

ASTM G63                  Standard Guide for evaluating Non-metallic materials
for Oxygen
ASTM G88                  Designing Systems for Oxygen Service
ASTM G93                  Standard Practice for Cleaning Methods and Cleanliness
Levels for Material and Equipment Used in Oxygen - Enriched
ASTM G94                  Standard Guide for evaluating metals for Oxygen
Service
ASTM G128                Standard Guide for Control Hazards and Risks in Oxygen
Enriched Systems
CGA G-4.4                  "Industrial Practices for Gaseous Oxygen Transmission
and Distribution Piping System" from Compressed Gas Association.
CGA G-4.1                  "Cleaning Equipment for Oxygen Service" from
Compressed Gas Association
EIGA 33/97/E              “Cleaning Of Equipment for Oxygen Service” from
European Industrial Gases Association
EIGA/IGC Doc 13/02/E Oxygen pipeline systems EIGA/IGC Doc 13/03 Oxygen cleaning systems 
NASA 1113                Chapter 5 - Oxygen from NASA Glenn Safety Manual
NFPA 51                     Standard for the Design and Installation of
Oxygen-Fuel Gas Systems for Welding, Cutting, and Allied Processes from National fire protection Association 
NFPA 780                   Standard for the Installation of Lightning Protection
Systems from National fire protection Association

And lastly,

Use Small case while writing a mail. Writing is caps is "Shouting"

COULD ANYONE GIVE ME ANY INFORMATION ABOUT THE DESIGN OF UNDERGROUND PIPELINE CONTAINING OXYGEN USED FOR WELDING IN A SHIPYARD. Q=1000 M3/H. OP. PRESSURE = 15 BAR. WHAT KIND OF A MATERIAL TO USE. CAN CARBON STEEL PIPE BE USED. or stainless steel to use.

IS THERE ANY THRUST BLOCK NEEDED. PIPELINE IS ABOUT 10 KM. THANKS IN ADVANCE
