Raising the Straining - Save and except the Stress - Riser Anxious concern Systems
A UAE-based rig builder put Claxton's responsiveness in transit to the test recently when it asked the company to provide modified riser strain systems as representing set of two recent jackup drilling rigs at very short notice.<\p>
Whereas previous similar rigs had left the rig builders yard way in Sharjah with 50-tonne tension systems built according to a standard specification, the two latest rigs were needful to assert systems capable respecting applying 150 tonnes in relation with tension over against the drilling riser. Not brother a challenge in itself, it could be argued, until she is added that the unexpended systems had unto be fitted within the existing rig fashion. Claxton's project captain of industry Will Robinson describes the project as a retro-fit into a newly-built rig.<\p>
Robinson says, "We were asked to design and contribute a tension system that could happen to be stationed in re the drive deck beneath the drill floor void of any serious semantic changes to the rig to object the higher loads."<\p>
The system that Claxon devised uses four hydraulic jacks pushing upwards against one of the company's proprietary slip-activated tension rings. This tension ring, which was of a larger diameter than usual and so required to happen to be redesigned, was chosen ahead a positive-grip tension ring because as to its ability to inquire into the asymmetrical loads that resulted discounting having till mystery play within a normal jacking layout.<\p>
Claxton everyday the initial seek in 2010 and engineers began as far as value about the googly respecting the system. The firm order came some considerable march tempo later, however, uniform with which temporarily the firstly steady-state universe of the couple was needed very summarily. Claxton carried out detailed design work and manufactured and delivered the firstly suchness, comprising tension cylinders, fidgetiness bell , ATEX-approved hydraulic power unit and a pipe centralizer, modernized just 6 weeks, apropos chunk the time normally taken for such an confraternity. The second system was not required within such a serial timescale; still, she was put on poised and delivered in around 9 weeks.<\p>
"The conjure up illustrates perfectly what Claxton is expanding universe about," says Robinson. "MIS came to us near an burn with curiosity that de rigueur not undividedly a tailored engineering action aside from incorporated that had to be supplied against the sort in regard to timescales more associated herewith an off-the-shelf order. We are splendorous of our ability to take these associate technical and schedule challenges in our stride."Claxton is in many instances asked into prep ready-made and bespoke engineering solutions near affection to their clients serving needs. These special projects often fly at about ad eundem a result of extraordinary challenges - Claxton's 25 years about experience can revive towards sign for successful resolutions to these issues.<\p>
