1.0 Introduction

LLOG has done recent metrology on the Neidermeyer field and have determined that the south flowline jumper needs to be recovered and reworked due to changes in the initial metrology measurements.

2.0 General Information

2.1 Locations

MC 253 South PLET (flowline) SN 18811

2.2 6" Jumper

6.625"OD x 0.750" WT, API 5L Gr. X65 Insulation: GSPU, 2" thick Jumper length/weight in air:

MC 253 South: 60714 Kips

2.3 Initial Conditions -Jumper will be flushed with brine to 2 times the jumper volume prior to arriving in the field

-The plet and manifold valves will be closed after the flushing operation.

3.0 Jumper Removal

3.1 Mobilize ROV vessel to MC 253 Neidermeyer field.

3.2 Locate jumper and perform video survey. Call Delta House and confirm the Neidermeyer field is powered down and wells are shut in.

3.3 ROV to setup rigging on jumper and prepare to make cuts.

3.4 ROV to use super grinder to make cuts on belly 1' past the bend tangents.

3.5 Install plugs and recover belly section of jumper first.

3.6 ROV to rig up to PLET-side of jumper and unlatch the KLV8 as per FMC operating procedure. Install plugs and recover section to deck and put in containment or cutting box.
