Fiberglass reinforced plastic (FRP) has properties that, if disregarded, can lead to failure during operation. The same properties, if taken advantage of, can provide the user with performance superior to traditional alloy materials. This paper discusses principles in designing process and facilities piping systems with FRP.
Fiberglass reinforced plastics (FRP) equipment is fabricated by applying layers to build up the required thickness. Peel is a phenomenon peculiar to FRP equipment since the bonded layers could be peeled back at relatively low loads. This paper will cover peel definitions, peel test methods, and peel strengths.
The Oil & Gas industry is showing a growing demand for systems and equipment that allow for quick repair interventions on damaged subsea pipelines. Fiber-Reinforced Polymer (FRP) composite wrapping systems have been introduced and accepted as alternative temporary repair systems. Composite wrapping is an efficient repair method and well established for onshore pipelines. It has been successfully extended offshore and, recently, for subsea in shallow water applications with divers. This paper provides a critical overview of the subject technique, including advantages over traditional repair methods, pipe defect applicability, reference standards and specific state-of-the-art technology. Composite wrapping solutions for diver-less and deep-water applications are not yet available on the market. Critical challenges to overcome in order to afford the use of this technology for these applications are outlined. A development project is currently ongoing to achieve a deep-water composite wrapping repair solution with the aim of proposing innovative and cost-effective methods in support of subsea asset Inspection, Maintenance and Repair (IMR).
Offshore projects today are demanding ever more reductions in both CapEx and OpEx. Tertiary structural products (eg handrails, gratings, ladders and platforms) made in steel may at first seem to be the lowest cost option, but steel is heavy and eventually suffers from corrosion which can be a significant drain on budgets and resources.
The benefits of FRP (fiber reinforced polymer) tertiary structural products for offshore oil and gas projects can be very significant, with substantial weight reduction, lower installation costs and minimal maintenance. But how can these recognized FRP benefits against steel be translated into actual CapEx and OpEx savings when used in oil and gas projects?
This aim of this paper is to offer answer to this question, by presenting a study of the projected Whole Life Cost and Value Proposition for the MARRS Offshore FRP Handrail using data drawn from the recent BP Clair Ridge Project.
