Jack-Up Analysis

Stewart Technology Associates (STA) is a leading engineering consultancy firm which focuses on marine and offshore structures, fluid dynamics and other diverse services and systems. With a broad range of expertise and a background in research, design and analysis, one of the major focuses for STA has been jack-up analysis.

Jack-up analysis has received a great deal of attention from STA and specifically Mr. W.P. (Bill) Stewart, P.E., President of Stewart Technology Associates who in recent years has consulted on a wide range of projects, co-authored papers and has chaired conference sessions.

Recently, Bill Stewart was invited to speak and submit a paper at the City University Conference, London on the topic of jack-up analysis. You can view this paper at the following link:
Mat-Supported Jack-Up Foundation on Soft Clay- Overturning Storm Stability
This paper is in regards to the Maleo Producer, a mat-supported jack-up converted to a MOPU (Mobile Offshore Production Platform located in a seismically active offshore region of Indonesia. Stewart Technology Associates undertook a large role in jack-up analysis and design related to the structures stability and resistance to overturning in storms.

Accompanying this paper is a PowerPoint presentation which includes illustrations, detailed computer graphics, tables and data from this project. You can view this file at the following link:

In addition, Bill Stewart has been active in a variety of conferences, specifically presenting the keynote paper along with co-authoring additional papers at the recent Offshore Technology Conference (OTC) session on MALEO MOPU: Fast Jack Up Conversion for Seismically Active Soft-Soil Site.

Below you will find a link to several papers on jack-up analysis submitted to the 2008 Offshore Technology Conference held in Houston Texas, USA 5-8 May 2008. Bill Stewart was selected as one of the sessions chairperson for the Maleo MOPU program.

The Maleo MOPU Project: Overview and Keynote Address
This overview paper describes the conversion, operations and benefits that can be recovered through a MOPU deployment. The Mobile Offshore Production Unit (MOPU), Maleo Producer is owned and operated by Global Process Systems and currently leased to Santos which operates it offshore Indonesia for gas production.

Seismic Time History Response of the Maleo Producer
This paper summarizes the procedures used to assess the structural adequacy of the Maleo MOPU platform for seismic loading. The Maleo Platform, located in the Madura Straits, offshore Indonesia is a seismically active region.

Detailed Geotechnical Investigation Around In-Place Mat Foundation Including T-Bar and CPT Comparisons
This paper describes the extensive site characterization undertaken to prove the stability of the Maleo Producer facility during both the design storm and seismic events.

From Jack-Up Analysis To Spill Containment, Drilling Operations Know They Can Count on STA

[Posted on May 14]

Stewart Technology Associates has a diverse client base and that is a major part of our success. By continuing to broaden our scope, both in terms of where we work and the services we provide, we've grown our reputation and become firmly established as one of the most trusted names in the offshore drilling industry. We conduct a wide range of services and are eager to meet the needs of our clients, whatever they may be. They may call upon us initially to perform a Jack-Up analysis but once that's complete and they've seen the benefits we provide, they're ready to continue working with us to improve upon other aspects of their operation.

We use OrcaFlex software when performing an analysis because it's represents the industry standard. Made by Orcina, OrcaFlex is used by over 170 organizations across the world, which is a testament to just how good the program has remained over the years. If you call upon STA to perform a jack-up analysis, you want to have confidence that the results will be credible so that you can use them to make adjustments to your operation. By giving our highly trained and experienced team the tools they need, such as OrcaFlex, we're ensuring that credibility and have repeatedly proven that our analysis can be counted on.

Clients that have had long term relationships with STA are already be familiar with our approach and that's why they know that whenever they need any type of analysis, there's no one more qualified to perform that work. This is true whether it's related to the jack-up system, single point moorings, steel cantenary risers or any of their offshore structures. Over the years, those relationships have been formed and made stronger each time a client relies on any of the services STA provides. This is a reputation that we've been building since being founded in 1986 and one we plan on continuing to build well into the future.

In addition to jack-up analysis and the other structures we assess in an offshore drilling operation, there are additional services that STA can be called upon to perform when needed. This includes determining if there are any potential issues related to the spill containment and oil spill cleanup methods that are ready to go into action when needed. Contact STA to ensure your team is ready to go into action when these types of incidents occur.
