WHY MODULARIZATION?
Limited / strained labor force
Limited workforce accommodation
Limited equipment availability
Harsh environment
Limited plot plan area or greenfield development Restricted geographic location
Environmentally sensitive
Limited time window

LESSONS LEARNED
1. 100% engineering completion before start of fabrication
Failure to accomplish this will result in potential for significant increase in on site direct / indirect hours

LESSONS LEARNED
2. Early involvement of EHL (Engineered Heavy Logistics)
Including an EHL as an overall advisor will optimise the logistics chain in time and money
Optimization of sea fastening, grillage and lashing equipment thru smart engineering
Determine logistics envelop
Highlight bottleneck for logistics strategy
Standardize lifting and transport supports as much as possible for all items
An EHL approaches design from an optimized construction point of view. Historically, in the offshore
industry, modularisation has been a lump sum based execution strategy. Therefore, the EHL will view
onshore projects from the same mindset.

LESSONS LEARNED
3. Select construction strategy at early stage Build high modules (only SPMT)
Build lower modules (SPMT with cranes)
Define maximum weights to optimize crane use (i.e. single crane for all lifts)
Including legs on the modules allows for flexible placement and storage

4. Interface management
Strong technical and operational experience for integration of marine and land contractors
Involved parties: MWS, marine contractor, customs, Client, site contractor, stevedores, longshoreman,
engineering design contractor, sea fastening fabricator, etc.
Clearly understand responsibilities of all parties prior to operations

LESSONS LEARNED
5. Management of the unexpected
We do not live in an ideal world. Always have a plan B (and perhaps even C)
Prepare for receiving cargo day or night
Sufficient support equipment (module stands, load spreader mats and miscellaneous equipment)
Where possible, have 2 discharge locations to reduce potential for expensive demurrage for transport
vessel and equipment

LESSONS LEARNED
6. Module Alignment
Module Alignment requires strong spotters to ensure proper positioning and no damage to piperacks
and equipment There will be misalignment within the module blocks. Differences in temperatures will make every pipe
extend or retrack.
Make sure you can compensate misalignment of this piping by using sleeves, or spacers and adequate
measuring and shimming equipment is available
Understand boundaries of approval with all parties

7. Shipping / Importation of Equipment
In environmentally sensitive areas special preparations (cleaning of equipment, customs paperwork,
inspections) are required Custom clearance for modules can be significant scheduling
8. Local Contractors
Well versed in local labor regulations and requirements
Experience with camp based work
9. Communication
