1.0 PURPOSE
This procedure identifies the standard methodology to which each Pride International operated
Mobile Offshore Drilling Unit (MODU) shall be held when conducting inspection of tanks or void
spaces.
2.0 SCOPE
This procedure addresses only the visual inspection requirements for each tank and void space.
This plan does not address non-destructive testing like hull thickness measurements. The
requirements for hull thickness measurements are addressed in Pride International’s Standard
Ultrasonic Testing Thickness Measurement Procedure.

Chacahoula Site, LA
3.0 GEOLOGY OF CHACAHOULA SALT DOME
3.1 REGIONAL GEOLOGY
Salt domes within the Gulf Coast occur in two regions: a northern belt through northern
Louisiana and Mississippi and a southern belt along the Gulf Coast and offshore. The
Chacahoula salt dome is located within the Coastal Salt Dome Province of Louisiana. In this
area, active sedimentation and subsidence has been occurring since the Mesozoic Era, resulting
in up to 30,000 feet of silt, sand, shale, and evaporites. During the Jurassic and early Cretaceous,
these evaporates were overlain by clastic and carbonate rocks deposited during alternating cycles
of marine transgressions and regressions. During the Cenozoic Era (70 million years to present),
large amounts of sediment were deposited in the Gulf Coast Basin and subsidence continues
under the accumulated weight of the sediment overburden.
The first movement of the Louann Salt probably occurred in either the late-Jurassic or the
Cretaceous. As the basin subsided, salt movement was probably initiated when the salt was
buried under a sufficiently large amount of sediment. Once salt movement commenced, the salt
would tend to form diapiric structures, such as salt ridges and salt domes where salt was buried
under a sufficiently large amount of sediment. Except around salt domes, regional faulting in the
Gulf Coast generally consists of large-scale, east-west trending, down to the basin (south),
normal faults. These faults generally parallel the Gulf Coast, and since sediment thickness may
increase dramatically on the downthrown side, they are frequently referred to as “growth faults.”
These faults usually are listric and usually have a dip of approximately 45 to 50° in the upper
sections and tend to flatten with depth.
Chacahoula dome is within the Gulf Coast geosynclines, characterized locally up to 40,000’
of Miocene and younger unconsolidated-to-poorly consolidated sediments. These sediments are
principally composed of sands and shales. The dome is situated just north of the east-west
Miocene age geosynclinial axis and slightly west of the arcuate noth-south trending Mississippi
structural trough.
A series of normal gravity faults, trending slightly northeastward, control the region’s
subsurface structure. This faulting, attributed to progressive subsidence of the depositional
basin, is roughly parallel to the Gulf Coast geosynclinial axis and is downthrown to the south.

16. Spr Expansion Conceptual Design Report
Chacahoula Site, LA
3.2 TOP OF SALT
Because it lies relatively close to the surface, the Chacahoula salt mass is classified as a
shallow dome. Lying within the Texas-Louisiana salt dome belt, it is elliptically shaped
structure with a rather flat top and steep sides. The location and top of salt maps are shown in
Figures 3-1 and 3-2, respectively. Near the top of salt, at an elevation of -3,000’, the east-west
axis is about three miles long; while, at a depth of about -15,000’, the long east-west axis jumps
to about 4.2 miles. The shallowest known salt occurrence was encountered near the center of
Section 72 at a depth of -1,100’ and is an isolated high point. The area enclosed within the -
2,000’ contour is approximately 2 square miles while the area enclosed by the -3,000’ contour
appears to contain a little over 3 square miles. Quality of salt mass is largely unknown at this
time. However, disseminated anhydrite is probably present in amounts of perhaps 3 to 7 percent.
Table 3-1 shows a data sheet of the dome.

Revision 02.1
Abrasive Wheels Page Page 1 of 4
Effective Date 02/16/07
Supersedes 11/01/02
1.0 STORAGE AND HANDLING
A. Immediately after unpacking, all abrasive wheels shall be closely inspected to ensure they
have not been damaged during shipping or handling. If there is visible damage to the
shipping container, special care must be taken in inspection of wheels.
B. Prior to storage, each wheel shall be given the “ring test”. For this test, small wheels may
be supported on the mounting hole by a pin or one finger, and tapped lightly with a
nonmetallic instrument (screwdriver handle, etc.) at a point approximately 45° to either
side of the vertical centerline of the wheel and one to two inches from the outer edge.
Large wheels may be stood upright on a clean, hard floor for this test. Wheels must be
dry, clean, and free of sawdust of packing material for this test. A “dead” sound indicates
a crack or damage to the wheel and it shall not be stored for use.
C. Wheels shall be stored in a dry area where they are not subjected to extreme temperature
changes. Storage rack or area shall be protected from excessive vibration or possibility of
physical damage to wheels.
D. Wheels shall be stored in racks, bins, or drawers in an orderly and safe manner facilitating
wheel selection with minimum handling.
E. Straight or tapered wheels of appreciable thickness shall be stored on edge in racks; two-
point support shall be provided to prevent rolling. Frequent partitions allow wheels to be
withdrawn without causing tipping of others in rack.
F. Thick, organic bonded (cutting-off) wheels shall be laid flat on a flat, horizontal surface to
prevent warping. No separating material shall be placed between stacked thin wheels.
G. Large wheels may be stacked on a horizontal surface with cushioning material between
wheels.
H. Small cup wheels and special shapes may be stored in containers or bins.
I. Great care shall be used in handling wheels to prevent damage. The following rules shall
always be followed:
i. Handle wheels carefully to prevent dropping, bumping, or exposure to moisture.
ii. No wheel shall be rolled hoop-fashion.
iii. Use trucks or other mechanical means to transport wheels too large for manual
handling.
2.0 INSTALLATION
A. All abrasive wheels shall be closely inspected and given ring test immediately prior to
mounting to insure freedom from cracks, or damage in storage and handling.
B. The rated operating speed of wheel shall be checked before mounting and must be equal to
or exceed to spindle speed of machine. Diameter of wheel shall not exceed that
recommended by machine manufacturer.

C. Wheel shall fit easily on spindle; spindle diameter shall not be more then .002” under
standard size. This easy fit assures safety clearance under operating conditions. If a
bushing is used, it shall not exceed width of wheel and shall not contact flanges.
D. Surface contacts of wheels, wheel blotters, and required flanges shall be flat and free of
foreign matter.
E. Required blotters shall cover entire area of wheel flanges; blotter thickness should not
exceed .025”.
F. Wheels shall be mounted between flanges, which shall not be less than one-third the
diameter of the wheel.
EXCEPTIONS: “Mounted wheels, portable wheels with threaded inserts or projecting
studs, abrasive discs (inserted nut or washer, projecting stud type), plate mounted wheels,
cylinder, cup or segmental wheels that are mounted in chucks, and special wheels using
adapters instead of flanges).
G. Flanges shall be of appropriate material (safety flanges of steel, other flanges of cast iron,
steel or other material of equal or greater strength and rigidity), dimensionally accurate, of
same diameter with equal bearing surface.
H. Spindle and nut on single and nut mountings shall be tightened only sufficiently to drive
the wheel and prevent slippage. Multiple screw flanges shall be tightened uniformly in a
criss-cross manner to 15-20 foot-pounds to insure even distribution of pressure over
flanged surfaces.
I. Bench and pedestal mounted wheels shall have:
a. Machine secured to bench or floor.
b. Tool rest adjusted within 1/8” of wheel.
c. Tongue adjusted within 1/4” of wheel.
d. Substantial guard that exposes no more than 90° of edge and side of wheel. (Guards on
wire wheels shall expose no more than 180° of work surface.)
e. Frame grounded either through 3-wire grounded cord or external grounding.
J. Portable grinding wheels:
a. Cup-type grinder shall be equipped with guard that encloses wheel sides to 1/3 of
wheel thickness.
b. Right-angle or vertical grinders shall be equipped with a guard giving a maximum of
180° of wheel exposure, and located between operator and wheel during work.
c. Other types of portable grinders shall have guard-limiting exposure on periphery and
sides of wheel to 180° with top half always enclosed.
d. Small pencil grinders with factory-mounted wheels are exempt from the above.
