1.0 Introduction
LLOG has done recent metrology at the Otis field and have determined that the MC 79 #1 jumper needs to be recovered and reworked due to changes in the initial metrology measurements.
2.0 General Information
2.1 Locations
MC 79, No. 1 (well) SN 19349
2.2 6" Jumper
6.625"OD x 0.750" WT, API 5L Gr. X65 Insulation: GSPU, 2" thick Jumper length/weight in air: 60713.61 Kips
2.3 Initial Conditions -The jumper will be flushed with MeOH to 2 times the jumper volume prior to arriving in the field
-The plet valve will be closed after the flushing operation.
3.0 Jumper Removal
3.1 Mobilize ROV vessel to MC 79 # 1. 3.2 Locate jumper and perform video survey. Call Delta House and confirm the MC
79 #1 field is powered down and well is shut in.
3.3 Inform the platform the ASD will be unplugged from the jumper.
