    Abstract: 本发明涉及一种抑制有形成水合物的组分的流体中形成笼形水合物的方法。更具体地,该方法可用于处理管中输送的石油流体流如天然气,以抑制在管中形成水合物节流。用于实施本方法的水合物抑制剂包括有N-乙烯基酰胺或N-烯丙基酰胺单元的基本上水溶性的聚合物。每单元在氮原子上均有两个取代基R1和R2,其中R1为氢或有1至6个碳原子和0至2个选自氧和氮及其组合的杂原子的烃基(支链、直链或环状),R2为有1至6个碳原子和0至2个选自氧和氮及其组合的杂原子的烃基(支链、直链或环状),其中R1和R2的碳原子数之总和大于或等于1但小于8。这种聚合物的一些优选实例包括但不限于N-乙烯基酰胺和取代的丙烯酰胺的共聚物。此共聚物的具体实例包括与丙烯酰吡咯烷(APYD)或丙烯酰哌啶(APID)共聚的N-甲基-N-乙烯基乙酰胺(VIMA),更优选与N-取代的甲基丙烯酰胺如N-异丙基甲基丙烯酰胺(iPMAM)和甲基丙烯酰吡咯烷(MAPYD)共聚的VIMA,以产生实施本权利要求方法的抑制剂。

    Abstract: PURPOSE: A pump connection structure of a natural gas supply system for offshore structures is provided to freely arrange a pump on an offshore structure by easily arranging the pump and a transfer pipe for supplying natural gas to the pump with a flexible hose. CONSTITUTION: A pump connection structure of a natural gas supply system for offshore structures comprises a transfer pipe, a pump, and a flexible hose. The transfer pipe is a path for transferring LNG from an LNG storage tank(101) to a high pressure gas jetting engine. The pump presses and discharges the LNG to make the LNG transfer through the transfer pipe. The flexible hose is arranged between the transfer pipe and the pump.

    Abstract: A method and system for restoring flow capacity to a submerged fluid conduit comprising a laser light apparatus to generate blue laser light to be impinged on the fluid conduit. The method and system include a frequency multiplier (15) for converting infrared laser light from a laser light generator (14) to blue laser light having a higher transmissivity in seawater. The frequency multiplier may be disposed on a submergible vehicle (2). In one embodiment, a non-submerged infrared laser light generator (14) supplies, via optical conduits (21), laser light to a submerged frequency multiplier (15) on the vehicle (2). Blue laser light, at a wavelength in the range of 440-500 nm, is emitted through an optical window and through seawater to impinge on the surface of the fluid conduit.
