Galveston, Texas-based offshore living quarters and high blast/high fire rated shelters provider LoneStar Marine Shelters has been contracted by Shell Offshore to fabricate the 607 ton, 76 bed auxiliary living quarters for the Mars A expansion project in the Gulf of Mexico.
The Mars A TLP, located in Mississippi Canyon block 807, is being expanded to provide additional living and office space for platform personnel. The new USCG-certified, single lift, three level structure is 72ft long, 40ft wide and 45ft high.
Unlike traditional living quarters, this structure is engineered around four ultra-heavy plate girders designed to support a temporary 230 ton offshore crane, which will be bolted on to the roof of the building upon integration with the platform. This innovative design feature is expected to provide the platform with exceptional operating capabilities.
EDG Consulting Engineers of Metaire, Louisiana designed the structure in accordance with Shell’s operational and safety standards. The perimeter of the building is constructed to meet a 0.65bar blast rating, A-60 & A-0 fire ratings, as well as stringent thermal and sound attenuation requirements.
The completed structure will be rolled onto an oceangoing barge at LoneStar’s reinforced bulkhead using self-propelled articulated movers. The building will then be braced, welded, and secured to the receiving barge ready for transit to the Mars A location in 3Q 2012.
