CCS - MV Bluefin 2017 V01 ROV

Project Overview: A range of solutions will be required to reach globally agreed emissions reductions targets for carbon dioxide (CO2). Carbon capture and storage (CCS) is part of the suite of technologies that will contribute to lowering atmospheric emissions of CO2 from Australia's energy system. There are a wide variety of technologies at various stages of technical and commercial readiness, with more development underway for cost effective CO2 capture and storage. Our research will provide new knowledge to inform cost-efficient measurement, monitoring and verification (MMV) of the environment of CCS projects in coastal waters.\n--o--\nThe SAAB Seaeye Falcon ROV was deployed five times on Tuesday 19th December 2017 to video the seafloor at various locations, with each deployment lasting approximately forty minutes. The ROV was deployed easily off the starboard of the vessel using the davit and pot hauler. The water was fairly turbid with poor visibility and surge current adding to some difficulty in piloting. As these were the first deployments of the ROV in an operational sense, a conservative approach was taken. Standard definition and High Definition video was captured of each deployment to allow future revision and study. A total of 350 GB of video was stored. The seafloor in the study areas was sparse with features well spread with notes taken of these features.

项目概述：要实现全球共识的二氧化碳（CO₂）减排目标，需依托一系列解决方案。碳捕获与封存（Carbon capture and storage, CCS）是助力降低澳大利亚能源系统向大气排放CO₂的技术组合之一。当前已有多种处于不同技术与商业化成熟度阶段的相关技术，且针对低成本高效的CO₂捕获与封存技术仍在开展大量研发工作。本研究将提供新知识，以支撑沿海水域CCS项目环境的低成本高效测量、监测与验证（measurement, monitoring and verification, MMV）工作。

2017年12月19日（周二），萨博Seaeye Falcon型遥控水下机器人（Remotely Operated Vehicle, ROV）先后5次被部署，对多个点位的海底进行视频采集，单次部署时长约40分钟。本次部署通过吊艇架与吊索绞车顺利完成，将机器人从船舶右舷下放入水。作业海域水体浑浊度较高，能见度较差，且存在涌浪流，为机器人操控增添了一定难度。由于这是该遥控水下机器人首次投入实际作业，因此全程采用了保守稳妥的操控策略。每次部署均采集了标清与高清视频素材，以供后续复盘与研究使用。本次任务共存储视频数据总量达350 GB。研究区域的海底地貌较为稀疏，各类特征分布均匀，作业团队已对这些特征进行了记录。
