Title: Underwater Work by Remotely Operated Vehicles (ROV's) Technology Development and Operational Experience
Abstract: ABSTRACT This paper describes experience with respect to underwater work carried out by Remotely Operated Vehicles (ROV's) on the North West Shelf Development Project, North Rankin "A" field located 135km off the North West coast of Australia. The field is operated on behalf of the joint venturers by Woodside Offshore Petroleum Pty Ltd. Installation of the platform and trunkline was completed in 1982 and from this date all underwater work has been carried out by ROV. Typical work includes detailed pipeline and platform inspections, underwater support for the installation of gravity anchors and associated guy wires, general construction support, underwater cutting, marine fouling removal, scour protection installation and pipeline stabilisation. Information presented in this paper is applicable to all phases of offshore oil and gas production that requires work to be done underwater e.g. exploration drilling, construction, operational inspection and maintenance. The paper describes special tooling procedures and systems developed to perform the above work. Also presented are new information and statistics associated with bulk marine fouling removal by purpose designed/bui1t remotely operated equipment. The paper concludes that significant underwater work can be performed cost effectively without exposing men to risks associated with the underwater environment and shows that a much larger slice of the underwater work "pie" can be achieved by ROV than has previously been generally accepted. Specific data related to time/costs associated with performance of significant aspects of the work are presented.
