Marine Construction

A specialised subcontractor hired to perform a specific skilled trade, such as electrical, welding, or pipefitting. They are typically engaged by a general contractor rather than the project owner directly. Trade contractors are responsible for supplying their own tools, crew, and trade-specific certifications.

A measure of how consistently a subcontractor completes work within the agreed timeline. Low compliance can trigger penalties, delay progress payments, or affect contract renewal. Tracking it helps field crews identify where mobilisation or scope changes are causing slippage.

Mesh filters mounted on shale shakers that separate drill cuttings from drilling fluid on the rig. Subcontractors handling fluid management or solids control must track screen condition and swap them regularly. Damaged or plugged screens slow operations and can trigger downtime charges against your crew.

The depletion of stored materials, parts, or consumables used during field operations. For subcontractors, rapid drawdown can trigger reorder costs and disrupt project timelines. Tracking drawdown rates helps avoid job-site shortages and unexpected procurement expenses.

A controlled heating and cooling process applied to welds after completion to reduce stress and improve strength. Subcontractors must confirm PWHT requirements before mobilising, as it adds time, equipment, and certified personnel to scope. Failing to price it into your bid can significantly erode job margins.

The point when a project owner formally approves funding and commits to proceeding with a major project. For subcontractors, FID is the trigger that converts preliminary work into confirmed scopes and purchase orders. Mobilisation planning, crew hiring, and equipment sourcing typically begin after FID is announced.
