CHEVRON - DESIGN VERIFICATION
Lake Maracaibo, Venezuela - 1999

Platform
Chevron LL-652 complex consists of a central production facility bridge-linked to a water injection and a compression platform.

Challenge
The 6000-ton production deck was the largest ever lifted using the Versatruss system. Chevron required verification of the strength and ductility of a number of components critical to the planned Versatruss installation of three integrated decks.

MSL Scope
MSL undertook independent finite element analyses to assess the stress distribution and magnitude of peak stresses for two critical locations. The first was the Versatruss boom to deck interface and the second was the penetration of each of the deck legs by two 5-inch thick sister plates.

Benefits
MSL’s reports assisted the client in achieving approval from the marine warranty surveyor for the Versatruss installation of the integrated decks.
