Houston, Texas May 7, 2013 – Welaptega Marine, world leader in Moorings Fitness for Purpose Assessments (MFPA), is at OTC Houston this week to deliver a paper on life extension of mooring systems on offshore floating production facilities.
The paper, entitled “Mooring System Life Extension using Subsea Inspection Technologies,” will be presented by Welaptega Business Development Lead Engineer Tyler de Gier who co-authored the paper with business development engineer Scott Allan and CEO Tony Hall.
The paper covers aging infrastructure, mooring failures, and risk based inspection techniques.
Life extension requires progressive inspection strategy
Determining the potential for life extension of an asset requires a comprehensive understanding of the current state of a mooring system. This is achieved by executing a well-planned inspection strategy followed by engineering analysis of quantifiable results.
The paper will discuss Welaptega’s Progressive Inspection techniques using 3D and 2D imaging technologies and dimensional technologies for measuring chain and rope mooring systems. Progressive Inspection identifies potential risks on moorings and underwater assets and then takes action to quantify anomalies to gauge their seriousness.
Advances in mooring systems
The Welaptega paper will be presented as part of an OTC technical session on Advances in Mooring Systems. The session will take Place on Thursday May 9, 9:30-noon in Room 600 of the Reliant Park Conference Centre. The session will be be chaired by Tomasz Matlak of Schlumberger and Subir Bhattacharjee of ExxonMobil Production.
Welaptega is part of the Nova Scotia OTC delegation lead by the Maritime Energy Association and the Nova Scotia Department of Energy.
Founded in 1969, the Offshore Technology Conference (OTC) is the world’s foremost event for the development of offshore resources in the fields of drilling, exploration, production, and environmental protection.// Learn More
Halifax, Nova Scotia _ Welaptega Marine has been awarded a contract to inspect the mooring system of the Nganhurra floating production storage and offloading (FPSO) facility operating in waters off the coast of North West Australia.
Welaptega has sent a team of specialist engineers to the facility to conduct a Progressive Inspection program using its Rope Measurement System (RMS) and 3D-modeling system (3DM).
“Our Progressive inspection philosophy is a guided examination of mooring systems that focuses on known problems and failure modes,” says Tony Hall, President and CEO of Welaptega Marine.
“When anomalies, wear or damage is identified, progressive inspection technologies are used to zero in on the problem and identify its characteristics and operational implications.”
Nganhurra FPSO is operated by Woodside Energy Ltd., and is the first oil production facility in the deep waters off the North West Cape.
The vessel operates in water depths of approximately 2000 feet and can process 100,000 barrels of oil per day. It has a storage capacity of one million barrels.// Learn More
During installation, a wellhead was impacted by a Blow-out Preventer (BOP). Geometry of the wellhead was required to facilitate removal and replacement of the damaged gasket.
