Each contractor has its own metadata, and that increases the time and effort needed to integrate the different solutions, he says.

An initiative, called Capital Facilities Information Hando- ver Specifcation (CFIHOS), under the International Asso- ciation of Oil & Gas Producers (IOGP) JIP 36, is working to develop specifcations to facilitate transfer of information between operators and suppliers, to make this easier.

Also, there’s development of a reference data library to sup- port standard equipment naming.

Another IOGP project, JIP 33, is developing standard equipment specifcations and another, DISC, is focused on the adoption of information standards. The OSDU forum is also developing open-source data standard models and platforms, mostly around well and reservoir data to date, says Deans.

That’s work in progress…

Akselos – Offshore Wind

Another approach to the digital twin is Akselos’ physics- based simulation technology. The technology, licensed from

MIT, is a reduced basis fnite element analysis (RB-FEA) soft- ware based on algorithms that the frm says are 1000 times faster than those typically used in conventional FEA analysis.

Unlike FEA, RB-FEA can also provide detailed structural in- tegrity simulations of entire assets, the frm says.

Akselos was founded about nine years ago and initially fo- cused on integrity management through a software-as-a-ser- vice (SAAS) model, with venture capital funding and support from Shell. But it’s also been looking at design engineering, helping to make fatigue calculations, across entire assets, faster and better. John Bell, SVP at Akselos says that FEA, the pri-
