Fairly damning. Jadestone now need to pull out all he stops to assure NOPSEMA... i mean seriously, you'd think after last time they'd be all over this kind of stuff.
Explanatory Statement
The operator of the Montara Venture facility, Jadestone Energy (Eagle) Pty Ltd, has not effectively assured
hull integrity, nor has it consistently adhered to established industry standards and practices. This has
resulted in an increased risk of hull and/or tank integrity loss, which may pose significant safety and
environmental risks.
Jadestone's corrosion management and repair strategy does not align with industry standards. The use of
temporary repairs, defined-life repairs, and increased inspection frequencies to justify reduced severity
ratings is not consistent with accepted practices. lndustry norms require permanent repairs where bottom
plate diminution or corrosion damage exceeds 25%.
Additionally, Jadestone is not meeting the inspection requirements of the 'Continuous Survey of Hull (CSH)'
scheme with their Classification society (Class) Lloyd's Register (LR). Several tanks and spaces have exceeded
the 5-year Class inspection interval required by Class - for example, the #L Port and #1 Starboard Cargo Oil
Tanks were last inspected in 2018. This contravenes LR Class rules. The vessel's Special Survey Status is
currently listed as'Postponed-Overdue'.
The Montara Venture facility has a history of integrity-related incidents, including hull breaches and cargo oil
piping failures, which have led to unplanned NOPSEMA investigations and restoration efforts conducted by
iadestone. While recent initiatives have aimed to improve inspection and repair activíties, Jadestone has not
demonstrated that these efforts are sufficient in reducing risks associated with hull integrity to ALARP.
Given the high number of active anomalies affecting the hull, tank, and cargo piping systems - including
several temporary and defined-life repairs - NOPSEMA has concerns regarding the effectiveness of
Jadestone's integrity management system. These concerns are based on recent inspection observations
indicating that the system is not adequately ensuring or maintaining compliance.
Accordingly, NOPSEMA has determined that it is necessary to issue this General Direction and require the
implementation of the specified controls and actions.
