The oil and gas engineer said the test, which it believes to be an industry first, demonstrates the “superior integrity” of the HG seal while also furthering the capabilities of POS-GRIP technology in Arctic conditions.
Normally, wellhead seals are classified as being able to withstand one of two separate temperature ranges, -59 to 82 degrees and -17 to 176, however in a single test the HG seal managed to cover both of these ranges.
The fact that the test was carried out with a sealing system previously used in a separate programme also demonstrated its reusability, the group said.
“By having qualified 'HG' annular seal technology across this impressive application spectrum, in terms of temperature and pressure, POS-GRIP wellhead seal technology can be readily adopted with the least amount of inconvenience by both operators and potential licensees”, said Plexus chief executive Ben Van Bilderbeek.
“We expect to license our patented POS-GRIP method of engineering which, with its further extended range of qualification standards, has the potential to elevate any wellhead supplier to a level that can technically and commercially compete, at the highest end of the market”, he added.
