MODULARISATION BEST PRACTICES
Schedule NO .
ITEM
1 To review material bulk items delivery e . g . batch-by-batch versus steel outfitting installation ( Topside / Piperack Modules – process / mezz ./ upper / top decks ).
2 To review the tag items or equipment delivery , integrate with construction schedule e . g . installation sequence ( on-ground ) & lock the lifting / erection date and sequence of topside modules and piperack .
3 To avoid changing the construction installation method , if tag equipment delivery delayed or slips due to vendor or engineering revision or quality control defects or FAT failure etc .
4 To review the back-end precommission priority e . g . topside utility module readiness for early system completion and estimated work carry-over or ship loose items e . g . benchmark of 80- 90 % on-ground work completion at the main shipyard .
5 Site piping installation strategy – hydrotest programme , RT strategise , golden weld , pneumatic test , store energy calculation and etc .
6 Site cable pulling strategy – E & I systemisation priority to be considered for early power energisation .
7 Progress measurement to be finalised and agreed , e . g . fabrication stage , integration stage ( including site pre-commissioning and commissioning ).
8 Expedite the delivery of equipment and material on the bottom parts of the process deck and other decks . The early delivery of equipment and material on site is better and applies just-intime ( JIT ) concept . Other potential risks such as preservation , mishandling , defects need to be controlled and enforced .
Engineering Co-ordination & Resolution NO .
ITEM
1 Issued for construction drawings ( IFC ) versus yard shop drawing e . g . engineering consultant IFC revision ( late vendor incorporation especially on equipment base plate ).
2 Engineering Safety Study Report and Escape Route e . g . late incorporation of the finding versus IFC deliverables thus impacting yard shop drawing production and revision and cutting plan activities .
3 Early finalisation of pad eye calculation and material delivery in order to support the module or deck lifting date or schedule .
4 Early finalisation of painting specification e . g . CSP / PSP and if possible , the same vendor or subcontractor .
5 Early finalisation of scantling calculation e . g . standardisation of plate size .
6 Early finalisation of topside module structure and piperack calculation e . g . to have separate piperack and topside modules .
7 Early finalisation of electrical system and layout to cater to the early PO for topside electrical system and equipment e . g . due to construction sequence deck by deck ( bottom to top level ).
8 Early finalisation of steel outfitting scope of work e . g . prioritise according to constructiondriven schedule ; process deck ( bottom part first or in-parallel for other decks , if the yard space permits ), and module lifting and delivery date ( 1 st batch ; utility modules , 2 nd batch : pre-treatment modules etc .).
9 Early agreement or approval on vendor / subcontractor work scoping at site or yard .
