摘要

本文基于一项正在进行的多参与者研究,该研究的重点是无人驾驶或“通常无人值守设施”(NUIs)概念的发展,这些设施可用于经济地回收搁浅的油气储量,这些储量对于传统的浮式生产储卸(FPSO)船来说太小,而且距离现有设施太远,无法进行回接。该研究的主要目标是以新颖的方式应用现有技术,并利用数字化的最新进展,通过促进远程控制、远程监控和减少维护需求来开发低人员配备概念。这项研究吸引了关键技术供应商和运营商,他们提供了运营专业知识,并定义了未来的运营理念。船级社、船厂和安装承包商正在验证这些概念。本文探讨的具体NUI概念是一种无人生产浮标,该浮标在技术上和经济上都是可行的,可用于开采较深水域的小型油气藏。该案例研究是对北海一个小型深水海上开发项目的现实逼近,然而,它并不是基于任何特定的前景。案例研究的设计基础(BoD)已经被定义为涵盖一系列API重力,确保由此产生的上部设计概念是稳健的,并且适用于未来的一系列实际油田开发,而无需进行重大的重新配置。研究了无人生产浮筒的技术和经济可行性,考虑了气体压缩、处理、分离的替代方案;供热和制冷、发电、自动化系统和数字化。本文介绍了生产浮标的设计、经营理念、自动化和数字化等方面的成果。

New Concepts for a Normally Unattended Installation NUI – Design, Operation, Automation, and Digitalization
This paper is based on an ongoing multi-participant study which focuses on the development of concepts for unmanned or "Normally Unattended Installations" (NUIs) that can be used for the economic recovery of stranded oil and gas reserves considered too small for traditional floating production storage and offloading (FPSO) vessels, and too far away from existing facilities for tie-backs. The primary objective of the study is to apply existing technologies in novel ways and to utilize recent advances in digitalization to develop low manning concepts by facilitating remote control, remote monitoring, and reducing maintenance requirements. The study engaged key technology vendors and operators, who provided operational expertise and defined future operation philosophies. Concepts are being validated by classification societies, yards and installation contractors. The specific NUI concept explored in this paper is an unmanned production buoy that proved to be technically and economically feasible for the recovery of small hydrocarbon pools in deeper water. The case study is a realistic approximation of a small deepwater offshore development in the North Sea, however, it is not based on any specific prospect. The case study Basis of Design (BoD) has been defined to cover a range of API gravities, ensuring that the resultant topsides design concept is robust and applicable to a range of real field developments in the future without significant re-configuration. The study into the technical and economic feasibility of the unmanned production buoy considered alternatives for gas compression, treatment, separation; heating and cooling, power generation, automation systems, and digitalization. This paper presents the outcomes with respect to production buoy design, operating philosophy, automation and digitalization.
