E&I (Electrical and Instrumentation)

A centralised owner or operator division that oversees large-scale capital projects and manages contractor relationships. Subcontractors typically submit bids, invoices, and compliance documents through the MPO rather than individual site teams. Knowing your MPO contact streamlines approvals, change orders, and payment processing.

Equipment or materials with extended procurement timelines, often weeks or months. Subcontractors must account for these delays when scheduling mobilisation and submitting project timelines. Late delivery can stall field work and trigger costly standby charges.

When a subcontractor provides their own tools, equipment, or materials rather than relying on the prime contractor or client. This shifts procurement responsibility — and often cost risk — directly to your company. Pricing your bids correctly to recover these costs is critical.

A company hired to deliver a project from design through build, acting as the main contractor above subcontractors. As a subcontractor, your client and contract holder is typically the EPC, not the asset owner. They control scope, scheduling, and invoice approval on site.

A lightweight gas turbine adapted from jet engine technology, used for power generation and compression on oil and gas sites. Subcontractors are often called in for maintenance, hot-section inspections, and component exchanges. These units start up quickly and are common on remote or temporary installations.

A coastal or estuary facility where bulk commodities like LNG or crude oil are loaded onto marine vessels for export. Water depth fluctuates with tides, affecting vessel scheduling and your crew's access windows. Subcontractors must plan shifts and equipment mobilisation around tide tables and vessel berthing schedules.
