Abstract:

Ship pipelines are the most efficient and cost-effective devices for liquid transportation. However, the lack of monitoring methods for minor or invisible pipeline leakage hinders the development of intelligent ship pipeline management. Herein, a self-powered liquid leakage sensor (SLLS) based on a liquid-solid triboelectric nanogenerator (TENG) for ship pipeline monitoring is proposed, aiming at real time detecting, locating, and identifying the invisible and minor leakage of the ship pipelines. The proposed sensor mainly consists of a steel electrode and Si02/ PT F E based superhydrophobic coating, where the contact-separation between coating and leakage droplets can generate electric signals displaying leakage droplet information, such as incident angle, temperature, height, and volume. With the help of the unique S i02 / PT F E based coating, the sensor posses self-cleaning, superhydrophobic and wear-resistant characteristics, making it suitable for environments with vibration, high temperature, and humidity. Moreover, the coating can also combine with the existing steel structures of the ships to form the large scale sensor arrays for leakage information identification. Through the experimental data investigation and analysis, the SLLS has the capacity of obtaining the minor or invisible leakage droplets information with high accuracy, which indicates great promise for employment in practical ship pipelines monitoring.

1 Introduction

The ship pipelines, as the safest and a cost-effective de-vices for liquids transportation [1], are the significant components of the ship, ensuring the stability of the voyage and meeting the normal needs of the crews and passengers[2]. However, pipeline leakage is a threat to ship operation, mem-bers' safety, and marine environment pollution [3]. Typical causes of wear and corrosion in pipelines include the vibration, high temperature in the cabin environment [4] or hu-man sabotage[5]. In recent years, several leakage detection technologies have been developed to locate the position of ship pipeline leakage. Manual inspection is the most com-mon method, which has a high accuracy for the larger leak-age location, but limited by the responsibility and experi-ence of the inspector. Furthermore, the manual inspection has low accuracy for invisible leakage in pipelines, and the inspection is discontinuous, since the large pipelines num-bers and the scattered distribution. Thus, methods based on multi-type sensors are proposed [6], containing the acoustic sensor[7], infrared sensor [8], fiber optic sensors [9], and ultrasonic flow sensor [10]. These sensors detecting and locating pipeline leakage rely on the pressure, temperature, den-sity, flow rate or sonic velocity information. However, their insensitive to low liquid level volumes leads to a detection difficult in minor leakage and limits the further intelligent application [11], [12]. Thus, the design of an effective sensor for detecting invisible and minor leakage in ship pipeline is still a challenge.
