mounted at the upper ends of support arms 36 and 38,
respectively.
To support the heavy loads which are placed on the
deck 40, a truss 46 is provided beneath the deck 40 and in
cludes beams and cross braces. An oil well drilling rig
48 is mounted on deck 40. Deckhouse 50 is also mounted
on deck 40 to provide for storage of machinery and liv
ing quarters for the crew.
This invention relates to marine vessels. More par
ticularly, this invention relates to a barge constructed to
have stability that provides for e?icient performance of
various jobs on the barge, such as drilling for oil, laying
pipe on the bottom, and the like.
Referring particularly to FIG. 3, in order to position the
work platform 14, a pair of rollers 52 are rotatably
mounted on stub shafts 54 extending from opposite edges
of deck 40. The rollers 52 are slidably received in tracks
Heretofore, various barge designs have been proposed
for conducting off-shore operations. Some have been de
signed for mooring on location with a plurality of an
chors. But, due to wind, waves and currents the barge
is moved from the desired location. Such barges have
failed to provide the stable platform necessary for many
operations, such as drilling for oil and laying pipelines.
Other prior drilling barges have been designed for ?ood_
ing so that the barge sinks to the bottom with the entire
barge resting on the bottom. In order to move these sunk- '
en barges, considerable time and power are required to
pump the water from the ?ooded compartments to re?oat
the barge.
The present invention resides in the concept of a barge
constructed to provide a stable work platform at desired
locations and also be conveniently and readily movable
to new locations.
Brie?y stated, the barge of the present invention in

cludes a hull enclosing a buoyancy chamber. A stabilizing boom is secured to the hull and extends for a substan
tial distance outwardly from the hull. A work platform
is pivotally mounted on the hull for supporting various
devices, such as oil drilling rigs, pipelines and equipment

or channel members 56 that are curved lengthwise but
U-shaped in cross section. Each track 56 is secured to
the framework of a derrick 18. While only one derrick
13 is shown in FIGS. 1 and 2, there are two derricks sym
metrically located on opposite sides of deck 40. Each
derrick 18 includes a derrick mast 60 having its lower
end secured to tank 62, a beam 64 secured at its upper
end to mast 60 and at its lower end to lower deck 66 sup
ported by braces 68 above hull 10. The lower deck 65
extends from the support arms 36 and 38 aft to the tanks
7e jointed at their upper ends to tanks 62. Cross braces
74 extend between the beam 64 and the derrick mast 60
further to strengthen the derrick 18.
To cause pivoting of work platform 14 with respect to
hull 10, a ?exible cable 30 extends from pad eye 82 fas
tened to the upper surface of the main deck 40, around
upper pulley S4 rotatably mounted at the upper end of
mast 60, around sheave 86 driven by winch 88, around
lower pulley 90 rotatably mounted at the lower end of
for handling the pipeline, oil and gas separators, and the
like. Valves are provided for ?ooding compartments
formed in the boom for lowering the outermost end of
‘ mast 60, and to pad eye 92 fastened to the lower surface
the boom to contact the bottom or bed beneath the body
of water. So that the work platform can be maintained

and buoyancy chambers 30, 32 and 34 have appropriate
valves for ?ooding by admitting water thereto.
When the barge reaches a desired location, the an
chors are dropped to form a mooring. Then the tanks
are ?ooded in the following order: tanks 119, tanks 104,
tank 168, tanks 103, tank 106, tanks 62 and chamber
34.
The stabilizing boom 12 and hull 10 swing or ro
tate downwardly until the ?ns 122 dig into the bottom.
Simultaneously with the ?ooding of the tanks, the winch
88 is operated to pivot the work platform 14 around
the pivotal shaft 16'to maintain the work platform sub
stantially horizontal. When the sleds 114 are touching
the bottom the’ barge is maintained vrelatively stable.
Various devices can be mounted on the work platform
14. Among these are a crane for construction work,
- oil~and gas separators, and pipe line and rollers to sup
port’ and feed the pipe line. When the barge is used
for pipe line laying, a stanchion with rollers can be
mounted on the boom I2 to support the pipe being fed
from the barge.

. The barge of the invention can be employed for various
uses. .Among such uses are: drilling for oil, both ex~
ploration and exploitation drilling; construction and fab
rication work necessary and-incident to drilling and pro—
ducing oilor gas; pipe line construction and repair work;
and; off-shore oil storage and testing. When the barge
is employed for oil storage, oil storage tanks can be
connected between the. boomlegs 10d and 101.
Thus it will be seen that the invention provides a barge
that is conveniently movable between locations and. has
stability at each location.

tion has been illustrated and described, it will be recog
