PLATFORM INSTALLATION
BARGE LOADOUT:
Various methods are deployed based on availability of resources and size of
- structure.
- Barge Crane
- Flat over - Top side is installed on jackets. Ballasting of barge
- Smaller jackets can be installed by lifting them off barge using a floating vessel with cranes.
- Large 400’ x 100’ deck barges capable of carrying up to 12,000 tons are available
PLATFORM FOUNDATION
n FOUNDATION:
– The loads generated by environmental conditions plus by onboard equipment must be resisted by the piles at the seabed and below.
– The soil investigation is vital to the design of any offshore structure. Geotech report is developed by doing soil borings at the desired location, and performing in-situ and laboratory tests.
– Pile penetrations depends on platform size and loads, and soil characteristics, but normally range from 30 meters to about 100 meters.
