SBM OFFSHORE : NOUVELLE INQUIETANTE

For whom the bell tolls: perhaps for Talisman on Yme

Yme 'ring of concern' for TalismanCanadian player Talisman Energy is reported to be facing a further headache on its Yme project as a new study has revealed the problem-plagued field platform may be unable to withstand wave impacts above a certain level.
Steve Marshall 09 February 2012 16:15 GMT
The stalled project is facing massive budget overruns and is now expected to cost around Nkr12 billion ($2 billion) – nearly three times the original estimate – due to a series of technical shortcomings on the field’s mobile offshore production unit (Mopu), built by SBM Offshore in Abu Dhabi.
A targeted start-up date in the late second quarter – more than three years delayed - is now in doubt due to major hook-up and commissioning challenges.
However, an analysis carried out by Force Technology on the effects of ‘ringing’ – or vibrations – from wave impact on the platform has uncovered a further construction defect that could threaten the usability of the Mopu, Teknisk Ukeblad reported.
Measurements made by Force showed that the platform could suffer structural movements from ringing caused by the impact of high waves due to the facility’s high “frequency”, which in turn is affected by its payload of topside installations such as a jack-up drilling unit.
The phenomenon is similar to the effect of singing at a certain pitch that causes glass to break or causing a bridge to collapse by having a large number of people marching across it at a certain pace.
The fault was apparently overlooked in the fabrication process by both SBM and operator Talisman, the report states.
A spokesman for Norway’s Petroleum Safety Authority (PSA) quoted by the publication said an initial ringing study carried out by classification society DNV had shown the impact of waves on the platform was 64% higher than previously, prompting Talisman to commission a further independent analysis from Force.
“The PSA has this winter been informed by Talisman that Force’s analysis has shown a greater impact than expected,” the spokesman said.
A letter from the operator to the PSA is quoted as saying: “Force Technology has carried out a preliminary ringing analysis that shows significantly higher tensions and deformations than documentation from SBM had shown.”
Professor in construction and materials technology at Stavanger University, Ove Tobias Gudmestad, said “resonance” from high waves on the platform could cause fatigue damage to legs and pipework due to structural swings.
“It could be a major challenge to find a technical solution to the problems if the effects of such fatigue are shown to be critical,” he warned.
