Offshore Project Management
Operator-side project delivery across EPCI, EPRD and decommissioning campaigns — contractor management, cost and schedule control, and technical assurance from award through offshore close-out.
Overview
Offshore projects are lost at the interfaces — between the well scope and the structures scope, between engineering and the yard, between the installation contractor's assumptions and the operator's expectations. Those gaps are rarely visible in the contract and always visible in the schedule.
VORYX provides operator-side project management and technical assurance from people who have sat on both sides: inside major operators, Tier-1 EPCs, installation contractors and fabrication yards. That means we know what a contractor's schedule float really is, and what a yard can actually deliver against a stated date.
We embed with client teams or run scopes as a managed PMC service, scaled from a single technical authority through to a full project management team.
Scope of Work
Contractor & Vendor Management
Tender management, technical bid evaluation, award support, contract administration, variation control and performance management.
Fabrication & Load-Out Support
Client site representation at yards, ITP and hold-point management, weight control, punch-list and load-out readiness assurance.
HSE, QA/QC & Compliance
HSE plan review and audit, quality surveillance, non-conformance management, and regulatory compliance oversight through execution.
Schedule & Cost Control
Integrated schedule development, progress measurement and verification, earned value, change control and forecast at completion.
Risk Management
Project risk register, quantitative schedule and cost risk analysis, mitigation ownership and escalation into the decision forum that can act on it.
Interface Management
Formal interface register across wells, structures, subsea, pipelines, commissioning and operations — with owners, dates and closure evidence.
EPCI / EPRD Technical Support
Technical authority support through engineering, procurement, construction, installation, removal and disposal phases.
Methodology
-
1
Set the execution basis
Agree the contracting strategy, work breakdown and the measurement rules for progress before mobilisation — ambiguity in progress measurement is the single most common source of schedule dispute.
-
2
Build the interface register
Identify every interface across disciplines and contracts at the start, with a named owner and a required-by date on each. This is cheap to do early and extremely expensive to do late.
-
3
Assure the engineering
Independent technical review of contractor deliverables against the design basis, with findings tracked to closure rather than filed as comments.
-
4
Be present at the yard
Client site representation during fabrication, testing and load-out. Weight growth, dimensional deviation and quality issues are found on the shop floor, not in progress reports.
-
5
Control cost and schedule honestly
Verified physical progress, earned value against a resourced baseline, and a forecast at completion that reflects reality even when it is unwelcome.
-
6
Close out properly
As-built documentation, dossier handover, lessons learned, and — for decommissioning — site verification survey and regulatory close-out reporting.

Frequently Asked
Do you provide embedded staff or a managed service?
Both. We embed individual technical authorities and project managers into client teams, and we run discrete scopes as a managed PMC service. The choice usually follows the client's own resourcing and governance model.
Can you represent us at the fabrication yard?
Yes — client site representation is a core service. Our team has supervised fabrication and load-out at major yards including McDermott Batam and Jebel Ali.
How do you manage a Tier-1 FEED or EPCI contractor?
Through clear technical assurance, a live interface register, verified progress measurement and early challenge of assumptions. Most contractor performance problems are visible in the engineering deliverables months before they appear in the schedule.
Do you take on multi-season decommissioning campaigns?
Yes. Multi-season programmes are managed as a campaign portfolio — weather windows, vessel availability, well readiness and disposal capacity sequenced together rather than optimised individually.
