파일럿 양광시스템 실해역 운용을 위한 선상지원장비 및 운용 S/W 개발

Abstract

In December 2015, KRISO has performed sea test of pilot lifting system consisting of buffer, lifting pump and riser at Pohang area in the East Sea of Korea. Here, the offshore operation means system installing and retrieving, high electricpower supply, control and monitoring, and lifting performance measuring for the lifting system. For the offshore operation, on-board support systems such as moon-pool structure, deck pipe-line system, nodule separation-measurement system, electric power supply system and operation S/W are installed on test vessel with moon-pool and offshore crane. The multipurpose support vessel, Normand Baltic is chartered, in which moon-pool and offshore crane are equipped. The moon-pool structure to install and retrieve the pilot system through moon-pool is manufactured. The deck pipeline system is to control and monitor pressure and flow in deck pipeline. The nodule separation-measurement system separates nodule from slurry or measures volume and weight of transported slurry for the specified time. The electric power supply system is to supply high power source to the lifting pump and buffer. Operation S/W controls the lifting system through measured data processing in sea test. This paper introduces about the on-board support systems and operation S/W in detail.
