Information on each boring log is a compilation of subsurface conditions and soil or rock
classifications obtained from the field as well as from laboratory testing
of samples. Strata have been
interpreted
by commonly accepted procedures. The stratum lines on the log may be transitional and
approximate in nature. Water level measurements refer only to those observed at the times and
places indicated in the text, and may vary with time, geologic condition or construction activity.

FIELD
OPERATIONS
Drilling Procedures
A drilling
rig mounted on a suitable offshore platform was used to perform the boring. The drilling
platform
is usually an anchored or dynamically positioned vessel or a mobile drilling platform. The borehole
is advanced with open hole, wet rotary techniques, using a drag bit attached to the drill pipe. A combination

drill cuttings and to provide lateral pressure to support the sides
of the borehole. A brief chronological

Summary of Field Operations is presented on Plate A-1.
Sampling Procedures
Samples are obtained through the open bore of the drill pipe. Cohesive samples are generally
obtained
by the push sampling technique, and granular samples by the percussion technique.
Push samples are taken
by lowering the sample tube into the soil formation with the weight of the
drill pipe. After the boring is drilled to the desired depth, the drill bit is raised from the borehole bottom, and
the sampler is allowed to fall through the drill pipe until it rests
on a catch ring above the drill bit. The
sampler
is then pushed about 24 to 30 in. into the soil by lowering the drill string. The sampler is retrieved
by pulling it out of the soil formation with the drill pipe
and then raising it to the deck using an overshot
retrieving device attached to a wireline.
After retrieving the sampler, the boring is advanced and the
sampling procedure is repeated. Samples obtained
in this fashion are noted by "PUSH" on the boring log.
Percussion samples are obtained
by advancing the sampler tube with a hammer and slide
assembly, which is lowered to
the desired sampling depth.
The hammer, a 175-lb sliding weight, is
repeatedly raised approximately 5 ft and dropped, to achieve a maximum penetration
of 24 in. or a
maximum
of 30 blows. The number of blows required to achieve 24-in. penetration, or the penetration for a
maximum
of 30 blows, is recorded on the boring log.
Samples recovered with the liner sampler are advanced 24 in. into the formation with the weight of
the hammer and slide assembly. Liner samples are noted as "WOH" on the boring log.
Water Depth Measuring Procedures
The water depth measurements are usually taken at the boring location
by one or more of the
following methods: (1) the vessel's echo sounder, (2)
an electronic bottom sensor, (3) pressure transducer
located
in the bottom sensor and (4) the first sample recovery during the coring operation. An initial water
depth
is estimated using the vessel's echo sounder. After the initial water depth estimate is made, a bottom
sensor
is used to more accurately measure the water depth. The bottom sensor is an electronic seafloor
sensor that
is operated on an electric cable and latches into the drill bit. The drill string is slowly lowered to
the seafloor until the electronic sensor signals that its tip has contacted the soil. The bottom sensor
contains a pressure transducer that provides
an independent water depth measurement. This pressure
transducer measurement also checks the pipe tally length used for the bottom sensor measurement. The
water depths obtained from these methods are then confirmed
by recovery of the first soil sample. The
Cavins wireline counter is used
in conjunction with the sampling equipment to obtain the mudline sample.
The water depth measurement thought to be most representative is indicated
on the boring log. After
completing
the soil boring, a confirmatory water depth measurement is sometimes taken. The coring vessel
is repositioned,
and the water depth is confirmed. Some variations in these procedures may occur due to
available equipment
and conditions at the time of the boring.

FIELD AND LABORATORY TESTING
A summary of the field and laboratory test results is presented on Plate A-2. In the field, each
sample
is extruded from the sampler and carefully examined, classified, and tested by the soil technician or
field engineer. Representative portions
of each recovered sample are appropriately packaged for shipment
to the laboratory
in Houston. The test procedures, which are in general accordance with ASTM Standards
---,"1:
(2006), are described in the following paragraphs.

Classification Tests
The classification tests, performed to verify field soil classifications, are assigned
to granular and
cohesive soils. These data are tabulated
on the Summary of Test Results, and most results are also
plotted
on the Log of Boring and Test Results.
For cohesive samples, plastic and liquid limits are determined to provide information for soil
classification. Water content and. density determinations are made for soil compression test
specimens~
For granular samples, classification tests are directed toward determining grain size. Grain-size
analyses performed include sieve analysis and/or the percent material passing the
No. 200 sieve. These
values are presented
on the Summary of Test Results.
Strength Tests
The undrained shear strength
of cohesive samples is obtained from Torvane, pocket penetrometer,
miniature vane,
and unconsolidated-undrained triaxial compression tests. The results are tabulated on the
Summary
ofTest Results and are plotted on the boring log.
The Torvane is a small, hand-operated device consisting of a metal disc with thin, radial vanes
projecting from
one face. The disc is pressed against a flat surface of the soil until the vanes are fully
embedded
and is rotated through a torsion spring until the soil is sheared. The device is calibrated to
indicate shear strength of the soil directly from the rotation
of the torsion spring.
The pocket penetrometer is a small, hand-held device consisting
of a flat-faced cylindrical plunger
and spring encased
in a cylindrical housing. The plunger is pressed against a flat soil surface, compressing
the spring until the soil experiences a punching type bearing failure. The penetrometer
is calibrated to
indicate shear strength of the soil directly from compression
of the spring.
The miniature vane test is used to measure the undrained shear strength
of cohesive soils. In this
test, a small, 4-bladed vane is inserted into either an undisturbed or remolded cohesive specimen. Torque
is applied to the vane through a calibrated spring until soil shear failure occurs. The undrained shear
strength
is determined by multiplying the rotation, in degrees, by the spring constant.
-
-
-
-
In the unconsolidated-undrained triaxial compression test, either an undisturbed or remolded soil
specimen is enclosed
in a thin. rubber membrane and subjected to a confining pressure of at least the
computed effective overburden pressure. The specimen is then loaded axially
to failure at a nearly constant
rate
of strain without allowing drainage. The undrained shear strength of cohesive soils is computed as
one-half the maximum observed deviator stress. Normalized stress-strain curves from undisturbed
UU
triaxial compression tests are presented on Plate A-
