SPEED-INCREASING NOZZLE FOR DISCHARGING GAS, GAS DISCHARGE SYSTEM FOR OFFSHORE STRUCTURES, OFFSHORE STRUCTURE, AND GAS DISCHARGE METHOD FOR OFFSHORE STRUCTURES
Provided is a speed-increasing nozzle 20 for discharging gas, configured such that: the suction effect due to the jetting of exhaust gas Gin entering from the inlet side causes surrounding air on the outside to be drawn in and mixed with the exhaust gas Gin to create mixed gas Gout; in this way, while the exhaust gas Gin is diluted with the surrounding air, the outlet-side gas flow rate of the mixed gas Gout is made faster than the inlet-side flow rate of the exhaust gas; and the resultant gas is discharged to the atmosphere. Accordingly, for offshore structures such as FSO and FPSO, even when the exhaust gas is heavier than air from an oil storage tank, it is possible to prevent the discharged exhaust gas from falling onto the production facility area of the offshore structure and, hence, from affecting production activity. Also provided are a gas discharge system for offshore structures, offshore structure, and gas discharge method for offshore structures.

A system includes mooring lines 20 arranged respectively in three to eight directions, and at least one of a plurality of offshore structures 10 included in the offshore structure group is moored by locking the mooring lines 20 in the respective directions with separate mooring bases 30, and at least one of the mooring bases 30 locks the mooring lines 20 which are connected respectively to three to eight of the offshore structures 10 in the offshore structure group. With this configuration, even when part of the mooring lines 20 mooring the offshore structures 10 is broken or the mooring function of the mooring bases 30 is lost, although the offshore structure moves, the offshore structure 10 is kept being moored by the remaining mooring-line group, so that the offshore structure 10 can be prevented from colliding with another offshore structure 10, thus making it possible to moor the offshore structure 10 at the offshore installation site safely without excessively increasing the strength of the mooring lines 20 in the mooring directions.
The present invention moors at least one offshore structure 10 in an offshore structure group including a plurality of offshore structures 10 using mooring lines 20 provided in 3-8 directions, with the mooring lines 20 in the respective directions being fastened to different mooring bases 30. The mooring lines 20 connected to 3-8 offshore structures 10 in the offshore structure group are fastened to at least one mooring base 30. As a result, if, under severe weather and oceanic conditions, a portion of the mooring lines 20 mooring an offshore structure 10 is broken or the mooring function of the mooring bases 30 is lost, the offshore structure 10 moves, but the remaining mooring lines 30 continue to moor the offshore structure 10, so that the offshore structure 10 can be prevented from colliding with the other offshore structures 10. Therefore, the offshore structures 10 can be safely moored at offshore installation locations without requiring excessively increasing the strength of the mooring lines 20 in the mooring directions.
A guide plate having depressed portions is provided between an array of heat exchanger tubes, herein after “tubes”, arranged horizontally side-by-side and a next lower array of tubes arranged horizontally side-by-side, and is positioned with the lowest parts of the depressed portions near crest portions of respective lower tubes. The guide plate conveys a liquid D on outer surfaces of respective upper tubes onto similarly positioned lower tubes even when the tubes move in a right-and-left direction. A falling film heat exchanger installed in a ship, an offshore structure or the like can avoid reduction in heat exchange performance, even when the ship or the like inclines and swings, by substantially evenly distributing and dropping a liquid onto the crests of the tubes and causing the liquid dropped from the tubes located in an upper array to fall onto the tubes located in the next lower array.

In a bubble lift system, a pressurized chamber at an upper end portion of a riser pipe applies a pressure to an upper portion inside the riser pipe to suppress an increase in the volume ratio of bubbles to a fluid mixture rising inside the riser pipe in a shallow water region. The upper end of the riser pipe is not opened to the atmosphere but is inserted into the pressurized chamber under a high pressure to thereby prevent expansion of the bubbles and gas. In addition, a deaerator for discharging bubbles separated by a centrifugal force is also provided in a middle portion of the riser pipe in a shallow water region to distribute the bubbles more evenly inside the whole riser pipe. The bubble lift system and a bubble lift method thus provided are efficient and employable even in a deep water region.

FALLING FILM HEAT EXCHANGER, ABSORPTION REFRIGERATOR SYSTEM, SHIP, OFFSHORE STRUCTURE AND UNDERWATER OFFSHORE STRUCTURE
A guide plate 22A, 22B having depressed portions 22 is provided between an array of heat exchanger tubes 21 arranged side by side in a horizontal direction and a next lower array of heat exchanger tubes 21 arranged side by side in the horizontal direction, and is positioned with the lowest parts of the depression portions 22a disposed near crest portions of the respective lower heat exchanger tubes 21. Thus, the guide plate is configured to convey a liquid D flowing down on outer surfaces of the respective upper heat exchanger tubes 21 onto the lower heat exchanger tubes 21 having one-to-one correspondences to the upper heat exchanger tubes 21 even when an inclination in a right-and-left direction of the heat exchanger tubes 21 occurs. Having this configuration, a falling film heat exchanger installed in a ship, an offshore structure, an underwater offshore structure or the like can avoid reduction in heat exchange performance, even when the ship or the like inclines and swings, by substantially evenly distributing and dropping a liquid such as a coolant or absorber onto the crests of the heat exchanger tubes and causing the liquid dropped from the heat exchanger tubes located in an upper array to surely fall onto the heat exchanger tubes located in the next lower array.

FALLING LIQUID FILM HEAT EXCHANGER, ABSORPTION REFRIGERATION SYSTEM, SHIP, OFFSHORE STRUCTURE, AND UNDERWATER STRUCTURE
In this falling liquid film heat exchanger (20), a liquid dispensing device (10) that dispenses a liquid (D) to the outer surface of heat transfer pipes (21) distributed across a wide area is configured provided with: a dispensing tank (11); a plurality of discharge devices (12) that discharge the liquid (D) from the dispensing tank (11); and a first dispensing duct (13) that receives the liquid (D) from the discharge devices (12). The liquid (D) is led to a region that the first dispensing duct (13) handles, and the liquid (D) is dripped onto the heat transfer pipes (21). As a result, even when mounted in a ship, offshore structure, underwater structure, or the like, and there is tilting or swaying of the ship or the like, the falling liquid film heat exchanger dispenses a liquid such as a cooling medium or an absorbing solution in an approximately uniform manner and drips the liquid onto the peak of the heat transfer pipes, causes the liquid dripped from the heat transfer pipes positioned at the top row to reliably drip to the surface of heat transfer pipes positioned in a lower row, and avoids a drop in heat exchange performance.
