FINDING REGISTER

CTR found that piping route on TP- 04, the

elevation for new route would clash with existing

lamp. Therefore, it is required to relocate the

Lamp (MWPN )

CTR Found that piping route on TP- 04, the elevation for new route would clash with

existing pipe. Therefore it is required to re-route the pipe ( WPN2 )

Orientation of plating and H/R lay out T.O.P EL. (+) 16.146 (MWPS) and detail hatch cover framing plan is not matching, to be revise accordingly

Existing framing step landing clash with offloading frame extension deck module( MWPN & WPN2 )

Alternative solution :•Demolish the existing step landing frame to accommodate new frame offloading pump and rectify after new extension plaform installed.

Potential obstruction during Offloading Pump Installation : Cable trays, Lighting poles, Instrument stanchion

Connection at row 2’B’ to be detailed

Actual condition hook up connection Row2’B’ is different in detail engineering forfollowing issues:

• Row 2'B' Lower Deck MWPN

‐ Pump support/skid detail for mounting is not found ( all platforms ) in detail engineering, impact : additional material
