Abstract
Abstract A mooring arrangement is provided for drilling hull intended to be used in Arctic waters wherein the mooring lines are connected to the hull at points substantially below the waterline but extended up through passageways in the hull to anchor windlasses located above the waterline. The mooring lines are fed up through these passageways by attachment to the end of lines which have been fed down through the passageways and brought to the surface by inflatable means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
163 words
A mooring system for a barge, comprising: a. a passageway from a point on the outer surface of said barge below its water line to a point on said barge above its water line, large enough to permit passage of an anchor chain, b. an anchor windlass on said barge adjacent the opening of said passageway above the water line, c. an anchor and anchor chain, and d. means to pass the bitter end of said anchor chain through said passageway and onto said windlass while said barge is afloat and said anchor is engaged in subsea terrain, comprising i a line capable of passing through said passageway from the upper opening, and ii. means on the end of said line capable of passing through said passageway and coming to the surface of the water outside the barge, whereby the bitter end of said anchor chain may be attached to the end of said line and drawn through said passageway onto said windlass.
Claim 2
Dependent Claim
163 words
A mooring system for a barge, comprising: a. a passageway from a point on the outer surface of said barge below its water line to a point on said barge above its water line, large enough to permit passage of an anchor chain, b. an anchor windlass on said barge adjacent the opening of said passageway above the water line, c. an anchor and anchor chain, and d. means to pass the bitter end of said anchor chain through said passageway and onto said windlass while said barge is afloat and said anchor is engaged in subsea terrain, comprising i a line capable of passing through said passageway from the upper opening, and ii. means on the end of said line capable of passing through said passageway and coming to the surface of the water outside the barge, whereby the bitter end of said anchor chain may be attached to the end of said line and drawn through said passageway onto said windlass.
Claim 3
Dependent Claim
34 words
A mooring system as defined in claim 1, wherein said means on the end of said line comprises an inflatable means which is heavier than water when deflated and lighter than water when inflated.
Claim 4
Dependent Claim
22 words
A mooring system as defined in claim 2, wherein said inflatable means inflates in response to air pressure through a pneumatic line.
Claim 5
Dependent Claim
22 words
A mooring system as defined in claim 2, wherein said inflatable means inflates in response to a signal transmitted through said line.
Claim 6
Dependent Claim
27 words
A mooring system as defined in claim 1, wherein a plurality of said passageways, anchors, and anchor chains are provided symmetrically around the periphery of said barge.
