OMS SmartFitTM

Overview of Method

Two Steps:

Measuring

Fit-Up

Measuring

The separate video shows OMS setting up a laser measurement tool and measuring pipes

Measuring

Pipes Delivery by Cargo Barge

Cargo barge alongside Laybarge

Offloading Cargo Barge to Laybarge

Using the Crane to move measured pipe to the Laybargemain deck

Pipes Holding Area

Note Pipe Numbers

Note physical position, pipe number, end

designator, and any anode pipes

Sequence Pipes

Step 3 – Number Pipes for Riggers

Bevelling

Sorted pipe loaded to bevelling inbound rack

Bevelling is done

Rotation Marking

Datum Marking

Best Rotation

Spacer crew aligns rotation mark

Pipe easily/quickly moved to best rotation

Minimise Hilo → line up clamp works better

Meet project HiLo specification

Best fit-up → best welding → avoid repairs

Tangible productivity benefit

Welding

Root Bead

Further welding passes

Check Fit-up

NDT & Field Joint Coating

Pipe exits the firing line

Installation

Pipeline is laid from the stinger

1. Note pipe numbers at stack on main deck

2. Use SmartFitTM PC to determine sequence

3. Mark sequence for riggers to load for bevelling

4. Rotation marking of pipes on ready rack

5. Datum marking of pipes on ready rack

6. Check spacer crew aligned pipes correctly
