There was delay, quality issues observed in erecting scaffolding for hot pipelines along with insulation
removal during the shutdown outage and this led to delay in thickness gauging. In spite of repeated attempts
to improve scaffolding completion, thickness gauging at some point during 30 th day of shutdown had to be
stopped. In total, thickness gauging of 36 % of hot pipelines was completed.
However, there were very few surprises on hot pipeline gauging which were recommended for replacement.
Around 80% of modification drawings were taken up and executed. Balance could not be taken up due to
resource constraints and paucity of time.
Major structural staircase for CDU-II – Atmospheric column at top 6.0 mt elevation was already pre-fabricated
& same was erected at site by project.
Most of the structural work replacement planned earlier was executed during the shutdown except platform
replacement in the debutanizer columns near FCCU New Gas con. area.
Bench testing of 210 nos. of PSV/TSVs was completed against 373 nos. and 72 nos. of PSV/TSVs were not
taken up/ not released. Around 91 TSV’s / PSV’s found to be missing at site and action to be initiated for
procurement.
1.6.1.5 FLARE SYSTEM:
Consolidated list of PSV/TSV bench testing executed..Unit wise
There was no scope variation on Planned vs Actual wrt. Flare system and all jobs as planned were executed.
However, flare derrick structurals reinforcement including replacement of ladder & platforms and painting of
flare structures were done partially due to paucity of time.
