SEAR JIP

Promote the Subsea Equipment Australia Reliability Joint Industry Project

2017 - Phase 4

The SEAR JIP Phase IV scope delivered a cloud-based reliability database to collect asset and failure information from SEAR members with Australian offshore operations. The SEAR reliability database provides a low cost/high value method of capturing, and sharing all subsea failures and lessons learnt for this region and allows comparison of Australian subsea equipment performance with other industry data sources.

A subset of the SEAR JIP is the Transforming Australian Subsea Equipment Reliability (TASER), a testing program that is creating 'living laboratories' at selected locations offshore Northern Australia.  The TASER project was formed in December 2017, which is a collaboration between Chevron, Shell and Woodside. TASER also established a collaborative framework with subsea equipment vendors, including TechnipFMC, OneSubsea, BHGE, Siemens, Teledyne and Seacon. Vendors  loaned over 100 samples to be tested as part of the Subsea Test Structure (STS). Samples predominantly consist of innovative coatings and materials, specialized Subsea Control Module Mounting Base (SCMMB) configurations, ROV receptacles, electrical connectors and hydraulic couplers.

 

2016 - Phase 3

During SEAR JIP Phase III, the steering committee  addressed two challenges, which were considered critical to operators: marine fouling and umbilical performance.
Marine fouling  has been found to occur in Australian waters, especially in the northern waters (sub-tropical and tropical), and has significant impact, including the expense of maintenance  and premature equipment failure. Wood issued an Expression of Interest (EOI) to the industry, seeking for vendors willing to collaborate on improving equipment reliability in Australian waters. Over 70 vendors responded to the EOI. They presented technologies with the potential to considerably improve existing marine fouling problems; e.g. new materials, coatings and improved design concepts.
The gas generated within umbilicals in operation can lead to safety risks and failures. The origin and consequences of this gas are not well understood, raising concerns that unwanted gas could lead to poor performance of electrical systems, which is exacerbated in warm Australian waters. Wood discussed with the Umbilical Manufacturers Federation (UMF) opportunities to improve the reliability of umbilicals and address existing challenges.

 

2015 - Phase 2

The SEAR JIP Phase II focused on expanding data collection and initiating engagement with vendors. In consultation with the JIP participants, Wood identified potential causes of the observed equipment failures. During this phase it was highlighted that current failure reporting procedures were generally inadequate, contributing to the lack of progress regarding equipment reliability. To resolve this issue, SEAR JIP proposed to develop  a reliability database tool to provide operators with an efficient mechanism to capture their failure data and allow for reliability analysis.

 

2014 - Phase 1

In 2014, local operators identified subsea equipment that was failing prematurely and estimated the cost impact of poor equipment performance. With five fields in Australia having more than 100 failures over a six year operating period, the associated cost of the intervention campaigns was around AUD150 million.
