无人机在海洋油气领域大展拳脚(2)

“以前,我们会在恶劣天气之后派一名船员调查装置的受损情况。”在不久之后,该任务将由无人机代替执行。检查人员将把无人机收集到的数据同3D地图进行比对,借此可以发现装置的受损情况,为进一步检查提供依据。随着技术的推广,海上工业将把无人机投入新的工作领域,更高效、更安全地为人类服务。

“一项技术,你使用得越多,就自然越能发现它更多的用处。” Fotheringham表示,无人机可用于卸货作业、在FPSO和货船间传递文件,或者借助FPSO的传信绳索进行卸货作业。随着无人机与日常作业间的联系日益紧密,无人机飞行员未来很可能会成为海上作业员工的一员。“我坚信,总有一天,海上装置上会配有专门的训练有素的无人机飞行员。”Fotheringham还说,无人机也可以是事故发生后的第一反应者,或是搜救行动的关键一环。

市场需求将推动无人机制造商解决该技术目前的局限性,延长电池的续航时间,提高无人机的有效负载能力。随着海上运营商开始寻求任务自动化,减少现场人员数量并降低安全风险,这使得无人机的需求将会只增不减。

The offshore industry has been quick to embrace unmanned aerial vehicles (UAVs), or drones, for visual inspection tasks. The technology ticks a lot of boxes in these costconscious times — they are fast, inexpensive, and require far fewer people on deck and in transit. They improve safety while delivering better data, users say. Maersk Oil recognised the advantages of UAVs early on and made them part of its offshore inspection operations in 2013. “You could say we were early adopters of the technology,” says Mark Fotheringham, director of facilities and projects in the company’s UK business. “The market was quite limited for drones at that time.”

Drones provided a practical alternative to the type of inspections required at Maersk Oil’s North Sea installations, including the floating production, storage and offloading (FPSO) units Gryphon, at the Gryphon, Maclure and Tullich fields, and Global Producer 3, which handles production from the Dumbarton, Balloch and Lochranza fields. Regulations require periodic inspection of hard-to-access areas such as flare towers and the insides of storage tanks. That once meant the time-consuming process of erecting scaffolding to enable inspections or, for some challenging areas, hiring rope access crews.

Rope inspection, when practical, is a popular option because it requires fewer people and less time than scaffolding, and allows better access to confined spaces or difficult-toreach areas. UAVs take these advantages a step further, Fotheringham says.

“Ropes were a major step forward”, he says. “Drones are another major step forward” in reducing time and personnel. “Drone inspection is essentially a one or two-man show.”

Two-pronged approach

Two years ago, at Gryphon, UK company Cyberhawk Innovations conducted what it claimed to be the first inspection of a cargo oil tank on an operational FPSO (Upstream Technology 04/2016).

The procedure took less than a day and involved a two-person team consisting of an UAV pilot an inspection engineer.

“We have throughout worked closely with the drone company and have developed a great relationship where we innovate together, come up with new ideas, develop and test the technology,” says Fotheringham.

“Prior to the tank inspection we made several technical adjustments and tests of the drone, and these allowed us to fly the drone within the tank to take the video and pictures we needed.”

Maersk Oil has since extended the drone inspection programme to the 26 cargo tanks on the Gryphon and Global Producer 3 platforms. The technique gives a good general inspection — cameras, Fotheringham points out, have vastly improved since the early days of drones.

However, more detailed inspection requires closer, prolonged contact. But not necessarily human contact — in what the company says is another first, Maersk Oil is planning a more detailed tank inspection that will supplement drone surveys with a “crawler” device equipped with lights, highdefinition cameras and other equipment.
