Abstract
Abstract A support system for a marine turbine power plant may include an integral condenser. The support system comprised of plate girders and welded plate steel cover may envelop the condenser within the structure in order to save weight in the ship's payload. Certain modifications have to be made to adapt the support to include an integral condenser including the ability of the base to accommodate thermal expansion, noise isolation, structural centering of the condenser and steam flow through the turbine support members.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A system for supporting a marine power plant in a ship's hull wherein the marine power plant includes at least one steam turbine, the support system comprising: a plurality of power plant support girders mounted starboard to port and spaced apart in the fore to aft direction; plate members attached to the girders to form an enclosure; an opening in the topside plate of the enclosure for admitting steam into the enclosure from the steam turbine; end caps attached at opposite ends to the enclosure; a water inlet and a water outlet attached to at least one of the end caps; and, a drain well attached to the underside of the enclosure in fluid communication with the topside opening whereby the enclosure functions both as a power plant support and a steam condenser.
Claim 2
Independent Claim
133 words
A system for supporting a marine power plant in a ship's hull wherein the marine power plant includes at least one steam turbine, the support system comprising: a plurality of power plant support girders mounted starboard to port and spaced apart in the fore to aft direction; plate members attached to the girders to form an enclosure; an opening in the topside plate of the enclosure for admitting steam into the enclosure from the steam turbine; end caps attached at opposite ends to the enclosure; a water inlet and a water outlet attached to at least one of the end caps; and, a drain well attached to the underside of the enclosure in fluid communication with the topside opening whereby the enclosure functions both as a power plant support and a steam condenser.
Claim 3
Dependent Claim
28 words
The support system recited in claim 1 wherein the girders contained within the enclosure are formed with cutouts to permit the axial flow of steam within the enclosure.
Claim 4
Dependent Claim
53 words
The support system recited in claim 1 further comprising: at least one flex rail running fore to aft on each side of the support system and fixed with respect to the girders, said flex rails slidably mounted with respect to the ship's hull whereby axial thermal expansion of the support system is accommodated.
Claim 5
Dependent Claim
44 words
The support system recited in claim 1 further comprising: at least one "A" frame support mounted in the ship's hull and adapted to slidably engage the support system for permitting axial and vertical movement of the enclosure while restraining-athwart ship's movement of the enclosure
Claim 6
Dependent Claim
33 words
The support system recited in claim 1 further comprising: noise isolation mounts between the turbine and the enclosure whereby the transmission of noise vibration between the turbine and the ship's hull is minimized.
Claim 7
Dependent Claim
65 words
The support system recited in claim 1 wherein the steam turbine is drivingly connected to a gear supported in a gear casing and further including: a pair of plate box sections' extending fore to aft and attached to the turbine-condenser support, said gear casing supported by and bridging between said pair of plate box sections and said gear lying between said pair of box sections.
Claim 8
Independent Claim
148 words
A system for supporting a marine power plant in a ship's hull wherein the power plant includes a propulsion steam turbine drivingly connected to a gear and a ship's service steam turbine drivingly connected to an electrical generator, the support system comprising: a plurality of power plant support girders running starboard to port and spaced apart in the fore to aft direction; plate members attached to the girders to form an enclosure; openings in the topside of the enclosure for admitting steam into the enclosure from the steam turbines; a water inlet and a water outlet attached to the enclosure; and, a well attached to the underside of the enclosure in fluid communication with the topside openings, the propulsion steam turbine and the ship's service turbinegenerator set being supported on the topside plate and girders whereby the enclosure functions both as a support system and a steam condenser.
Claim 9
Independent Claim
148 words
A system for supporting a marine power plant in a ship's hull wherein the power plant includes a propulsion steam turbine drivingly connected to a gear and a ship's service steam turbine drivingly connected to an electrical generator, the support system comprising: a plurality of power plant support girders running starboard to port and spaced apart in the fore to aft direction; plate members attached to the girders to form an enclosure; openings in the topside of the enclosure for admitting steam into the enclosure from the steam turbines; a water inlet and a water outlet attached to the enclosure; and, a well attached to the underside of the enclosure in fluid communication with the topside openings, the propulsion steam turbine and the ship's service turbinegenerator set being supported on the topside plate and girders whereby the enclosure functions both as a support system and a steam condenser.
Claim 10
Dependent Claim
75 words
The system recited in claim 7 further comprising: at least one plate box section extending starboard to port; and, at least one pair of spaced apart box sections extending in the fore and aft direction and supported on opposite sides of the hull and each fixed to one end of the starboard to port box section to form a gear support subassembly, the subassembly being fixed to and a part of the overall support system.
