and designing new rigs.
NEW TLP TENDON INTERMEDIATE CONNECTOR - DESIGN AND TEST
Alpha Mahatvaraj, Offshore Products Manager, GMC Inc.
A TLP tendon intermediate connector has been designed, tested and supplied for a TLP project in offshore West Africa. This paper discusses
the design of the TLP tendon mechanical connector, including the extensive analytical work and design validation/qualifcation testing that
has been performed. The tendon connectors have been designed for operating extreme installation and survival load conditions per API RP
2T. The mechanical connector design has been successfully tested and validated for survival load conditions with no seal loss. The connector
has also been designed to meet or exceed C1 fatigue design curve per DNV-RP-C203. The availability of this connector expands the
procurement options for TLP tendon system components.
Mr. Mahatvaraj serves as offshore products manager for GMC Inc. He has more than 15 years of experience in mechanical design, product
development, testing and project management. He has an MS degree in Mechanical Engineering from Tennessee Technological University.
His recent projects include the development of mechanical connectors for dynamic pipeline and riser applications, design and engineering
management of a riser system for deep sea mining application, design of TLP tendon connectors and the delivery of management of top
tensioned drilling and production risers for brownfeld projects in the GoM.
PLATFORM LIFE EXTENSION
Eleni Beyko, Director, Technip
Many platform owners are considering life extensions for their ageing assets in the GoM, driven by the need to extend the economic life
of their assets, tie-in additional resources, etc. A variety of strategies are being considered by the owners to achieve life extension. This
presentation looks at Platform Life Extension by utilizing the technology and expertise of a major offshore platform contractor, proposing
to quantify the conservatism embedded in the original platform design, use measured motions and environmental data to hindcast fatigue
damage, and use Life Cycle Loading technology for realistic prediction of remaining life.
Dr. Eleni Beyko is the Director of Platform Life Services at Technip, USA. She holds a PhD in Naval Architecture and Marine Engineering
from the University of Michigan. As the Director of Platform Life Services at Technip, she oversees all offshore brownfeld projects in the
GoM, many of them dealing with Technip-designed deepwater spar platforms, and seeks to employ technology solutions in the area of
platform life services, including platform life extension.
