Airborne Oil & Gas has been invited by the Libra consortium to perform a failure mode, effect and critical assessment (FMECA) for a TCP riser that could be used at the Libra field offshore Brazil.
The request followed the preliminary feasibility study performed by Airborne and Wood Group Kenny, that showed a 45% reduction in top tension in a cost effective riser solution, using a hybrid riser design comprising of the conventional flexible pipe and the TCP section inserted at the mid-water depth, the company explained.
Henk de Boer PhD, engineering manager Airborne: “We are independent in our material choice and select the right material for every application. In this case, we assessed 3 different composite materials in the riser design and optimized it for installation, fatigue, top tension and pipe cost. Interestingly, the most cost effective riser solution turned out to be the technically best performing as well.”
