Design & Analysis

Design & analysis services together with engineering software have formed the back-bone of our business.  The Irish Sea Pioneer was designed by STA in the 90’s and continues to operate in the Celtic Sea. It is a sef-propelled jack-up with design optimized for working with unmanned gas production platforms.

The hull was built by Bollinger Shipyards in LA and the legs and jacking units were built by LeTourneau in TX.

A modified design with 750t crane is the “Irish Sea Pioneer Mk2” shown below.  Click on the picture to get an enlarged view:

OOSLFP – Open Ocean Stabilized Live Fire Platform for Missile Testing, for US Air Force.  This is a 5-acre floating concrete structure designed for permanent operations, moored in the Gulf of Mexico.

MOPU – MALEO PRODUCER – Indonesia.  The Maleo Producer is a converted mat-supported jack-up for gas production.  It is located in a seismically sensitive area and required extensive design and analysis efforts in order to obtain ABS certification.  A significant geotechnical site investigation effort was undertaken, partly from the platform, after jacking up on location.

A Roson was deployed from the installed platform and modified support framing and rigging was arranged to enable sampling right up to the edge of the mat and inside the mat cut out areas.

Classical geotechnical analysis supplemented by full scale measurement of ground disturbance.
