SSH number 5 Thickness Gauging requirements

SSH number 5 Thickness Gauging requirements

1. Suspect areas throughout the unit as deem necessary.

2. Comprehensive gaugings throughout of special and primary applications.

3. Leg well structures

4. Representative gaugings of deck, bottom and side shell plating of hull and spud cans

5. Substructure of derrick as deem necessary

6. Representative gaugings of internals of all preload and ballast tanks.

Definition of special and primary applications

Primary

Main structural members of lattice legs

Combination of bulkhead, side shell, bottom and deck plating within upper hull that forms Box or I main supporting structure.

Jack house supporting structure

Internal bulkheads, shell and deck of bottom mat supporting structure that distributes major loads either uniform or concentrated.

Fixed frames in jacking or self elevating systems

Moveable cantilever structure supporting drilling derrick

Special Applications

Vertical columns in way of intersection with the mat structure

Intersections of lattice type leg structures which incorporate novel construction
