 Non-generated loads (equipment and supplies- wet/dry -, empty area

loads, live loads, dynamic vibrations from rotating machinery, mud

pumps and operations, etc.),

 Design life (operating and fatigue),

 Accidental design loads (boat impact, dropped objects, fire and blast),

 Load combination cases (extreme environmental, operational,

serviceability, transportation, lift and launch),

 Damaged stability and or redundancy requirements (missing member,

flooded leg or compartment),

 Preferred material classes,

 Design regulations, codes and recommended practices,

 Appurtenances and their locations (escape and evacuation equipment,
escape ways, stairs. boat landings, barge bumpers, conductors and J-

tubes, mud-mats, etc.),

 Corrosion protection requirements (type-anode, impressed current- and

life),

 A narrative of construction methods and procedures that will have an

impact on the platform configuration and sizes (skidding and load-out

procedures, pulling points, lifting eyes, launch skids etc.),

 Verification and certification requirements,

 Any other owner requirements that will impact detailed design (jack-up

drilling unit clearances, tender rig sizes and weights.

Detailed design (also called by some as the “execute engineering phase” or

“final design phase”) includes all engineering analyses; approved for construction

(AFC) detailed design drawings, specifications, procedures and reports required to

allow fabrication, transportation, installation, pre-commissioning, HUC, startup

and operations of a platform.

1. Engineering analyses include all design conditions:
