Cable cabin penetration sealing device for FSRU

Abstract

The invention discloses a cable cabin penetration sealing device for FSRU, and aims at providing the cable cabin penetration sealing device which can conveniently allow an installing person to inspectwhether or not the installed cable cabin penetration sealing device can normally operated and can timely discover the leakage problem of the cable cabin penetration sealing device for the FSRU. The device comprises a liquid cargo cabin joint, an intermediate assembly, a lower cavity assembly, an upper cavity assembly and a power cable, wherein the intermediate assembly comprises a middle sealingsleeve, an upper cable joint and a lower cable joint which are provided with openings at both upper and lower ends, the lower cavity assembly lower sealing sleeves with openings formed in the two ends, the upper end of the lower sealing sleeve is in sealed connection with the lower end of the intermediate sealing sleeve, the lower end of the lower sealing sleeve is in sealed connection with a portof the liquid cargo cabin joint, the upper cavity assembly comprises an upper protecting sleeve with openings formed in both upper and lower ends, the lower end of the upper protecting sleeve is connected with the upper end of the intermediate sealing sleeve, and the power cable comprises a cable out of the cabin, a cable in the cabin and a connecting cable which is located in the intermediate cavity.

Description

technical field [0001] The invention relates to a cable penetration sealing device, in particular to a cable penetration sealing device for FSRU. Background technique [0002] FSRU is the abbreviation of Floating Storage and Regasification Unit (English Floating Storage and Regasification Unit), also known as floating regasification unit or floating LNG regasification unit. At present, submersible cargo pumps are often used in FSRU for LNG transfer. Since the motor is submerged in the LNG in the natural gas liquid cargo tank, it is directly cooled by the low-temperature fluid it transports, so the cooling effect is good, the motor efficiency is high, and there is no humidity. Influenced by corrosion and corrosion, its insulation will not deteriorate due to temperature rise; however, since the submersible cargo pump is immersed in the LNG in the natural gas liquid cargo tank, the power cable of the submersible cargo pump needs to be penetrated into the natural gas liquid carg...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the cable penetration sealing structure in the prior art is not only difficult to detect whether it can work normally after installation, but also difficult to find out in time once the sealing position leaks during use, and provides a A cable penetration sealing device for FSRU that can not only facilitate the installer to detect whether the cable penetration sealing device can work normally after installation, but also detect the leakage of the cable penetration sealing device in time
