No forecast populated. Needs a validated reservoir and production model.

Historical items come from the company website and carry their verification status. Simulation events are generated by the twin. Tap any item.

Engineering command centre cycle 1 s

Prototype agents. All 30 are simulated, AI-assisted workspaces running inside this page. They are not connected autonomous workers and they cannot operate equipment. Every recommended check needs a named person to approve it.

Requisitions and orders

ID	Item	Stock	Min	Reserved	On order	Cover	Lead	Location	Equipment	Class	State

Every twin hour the inventory AI checks cover against lead time, reserves parts for open work orders, checks spares for any equipment with a predicted alarm, and proposes purchase requisitions. A person approves each one in the Command tab. Demo speed runs one twin hour per minute; real time runs once an hour. Items, quantities, minimums, lead times, unit costs and use rates are illustrative and assumed. In a field deployment stock comes from the operator's inventory system, read only.

Operations

Choke setting 32/64 in Significant wave height 1.4 m

Barriers

Weather and storm live metocean

Storm sequence

Rain, wind streaks and whitecaps follow the live wave height. Rain rates, the 1.35 gust factor, visibility, the pressure fall, whitecap cover and the 5.8 m storm peak are assumed. The storm runs in compressed time, about 70 s. Moving the wave height slider ends it.

Coating and corrosion UT wall loss . live crawler

Coating systems, breakdown per cent, nominal and measured wall, corrosion rates, grade bands and the minimum wall at 65.5 per cent of nominal are assumed. The magnetic UT crawler scans the leg A splash zone live in the twin.

Gas and H2S dispersion map live deck plan

Prevailing wind from 225 deg, SW

Detector layout, the release point at the test separator, the south west prevailing wind and the plume model are assumed. A screening view driven by the live wind, not a dispersion study. Wind direction drifts slowly around the setting.

Escape and evacuation

Drill sequence

Route layout, muster station allocation, badge counting, lifeboat seats and drill timings are assumed. The drill runs in compressed time and lowers lifeboat 1 only. Launch is left out above an assumed 2.5 m Hs.

Utility and quarters platform

Second platform at the bridge end. Bed count, loads, tank size and the module layout are assumed. Concept placement, not to scale.

Power generation and switchgear live power balance

Power balance

Two dual fuel gas turbine generators on the power deck of the utility and quarters platform, one duty and one standby. The 1,000 kW site rating per turbine, the 400 kW diesel G-001, the 4 s diesel and 12 s turbine start times, every load figure and the shed priorities are assumed. A trip sheds process and non essential loads until the standby turbine is on the bus. The effect of load shedding on production is not modelled.

Helideck and crew change

Helicopter type, seats, flight time and the 35 kn deck wind limit are assumed. The helicopter stays parked and tied down on the helideck between crew changes, assumed. It is a generic medium twin offshore type, not a specific make or model, modelled at about 13.8 m long with a 13.8 m five blade rotor and shown at 78 per cent scale so it sits inside the 12.8 m helideck. A real helideck is sized to the aircraft. The flight runs in compressed time.

Lighting and night operations

Sunrise and sunset are approximate for the Nkuku area. Light levels and lighting load are assumed. The cycle runs a 24 hour day in 4 minutes.

Supply vessel and waste backload

Waste manifest live

Vessel size, skip weights, the crane chart and the 2.5 m Hs lift limit are assumed. The backload runs in compressed time.

Oil spill drill Tier 1 . simulated slick

Spill response sequence

A drill on a simulated slick, no oil is released. Slick size and volume, the 90 m boom, the skimmer rate, the 85 per cent recovery and the 2.0 m Hs boom limit are assumed. The drill runs in compressed time, about 70 s, and holds during a muster.

Sensor and instrument register

Tag	Measures	Equipment	Value	Limits, illustrative	Calibration	Link	Quality

Every value is simulated. No instrument is declared healthy: SIM means the simulated value is inside its illustrative band. Alarm limits are placeholders, not approved set points. Calibration records were not supplied.

2027 to 2030 IoT compliance design basis

Standard	Covers	In this twin

The twin is designed to these standards. Certification needs the real system built, tested and audited by an accredited body.

Twin time	Oil bopd	Water bwpd	Gas MMscf/d	BS and W per cent	Well

Each sample is 10 minutes of twin time and one is taken every second, so a full 24 hours fills in under two and a half minutes. History before the page opened is backfilled from the twin model at the starting choke, assumed. All values are simulated.

Development roadmap

Phase 1, conductor support platformFabricated by CMES, installed by VMI and CMES

REPORTED

Phase 2, extended well test to FSOTest spread, produced water package, flowline, spread moored FSO

CONCEPT

Phase 3, FPSOFull field process and export tied back to the CSP

CONCEPT

Phase sequence from the earlier CMES and VMI announcement used in twin v1 (S24). It is not confirmed by the company website reviewed on 20 Oct 2026, which describes a phased plan led by appraisal drilling (S19). No FSO, FPSO, EPF, platform or pipeline has been selected in any supplied document. Layouts are concept placements, not to scale.
