1 OFFSHORE PIPELINE CONSTRUCTION PHASE  Pipe Laying : Normal S-Laying Method

2 OFFSHORE PIPE LAYING: Normal S-Laying Method

3 Step 1: PIPE BEVELING  Lift the pipe out of the supply barge onto the incoming rack  Pipe Tallying (pipe number, length, joint number)  Making the J-Bevel on pipe ends for Auto welding

4 Step 2: Station 1 (Fit up, Root and Hot Pass)  Preheat on pipe end prior to welding (based on approved WPS)  Fitting pipe ends to be aligned by means of internal clamp  Root weld followed by Hot pass

5 Step 3: Station 2,3,4&5  Filler passes on Station 2 and 3  Cap welding on Station 4  Visual Inspection on Station 5 Sta # 2 Sta # 3 Sta # 4 Sta # 5

6 Step 4: Station 6 (X-Ray) X-ray operators control the movement of the X-ray crawler inside the pipe Wrapping the film around the intended joint Radiographic intrepeters from HHI, Client and Migas are reviewing the X-ray result

7 Step 5: Station 7& 8 (Brush up and Cold Wrap) Sta # 8: Cold Wrap Sta # 7: Brush up

8 Step 6: Station 9 (FIELD JOINT COATING) & PULLING  Foam Coating performed by OJS (Offshore Joints Service)
