Prefabrication and use of<br />

large modules<br />

Why this very large extent of<br />

prefabrication?<br />

• Harsh weather conditions<br />

• Remoteness – lack of necessary infrastructure<br />

• Reduce the necessity of steel work at site<br />

• Higher productivity at construction yard<br />

• Reduce work at site in general -<br />

of the total estimate of 15 million man-hours to<br />

build the plant, 50 % is done at site.<br />
