Xmas Tree Overview

Provides a pressure containing method to safely cap the Well via its interface with the subsea Wellhead

Xmas Tree features:• Control, monitor and condition either produced or injected media.

(Designs for either 5000, 10000 or 15,000 psi wp)• Provides normal and failsafe methods of shutting the Well at the mudline• Provides a interface to re-enter the Well at any time during the life of the

field• Provides a platform/interface from which to monitor down hole pressure

temperature or ‘smart well’ systems & applications • Provides a platform/interface from which to inject chemicals either down

hole or at the Xmas Tree

Product Overview / Key FeaturesFoundation StructuresSeven Heads

Mudmat – Hard to medium soil conditions. Large areas

required, high slamming loads in splash zone.

Piles – not very commonly used. Special equipment needed during installation .
