Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Tide Gate

A one-way valve or flap gate that allows water to drain freely but prevents backflow from rising tides or high water levels. Subcontractors working on coastal or waterfront sites must account for tide gate locations when planning drainage, excavation, or utility work. Ignoring these structures can cause flooding, schedule delays, and scope changes.

Related Terms

Infill Drilling

Industry

Drilling new wells between existing producers to recover bypassed reserves in a developed field. For subcontractors, it means shorter mobilisation windows and back-to-back well programmes. Expect high crew utilisation but tight scheduling with little downtime between jobs.

Offshore Commissioning

Industry

The process of testing and activating offshore systems and equipment before handover to the operator. For subcontractors, this phase typically requires specialised certifications and offshore survival training. Mobilisation costs and remote logistics significantly affect bid pricing and crew planning.

Mini Crawler Crane

Industry

A compact, track-mounted crane used for lifting in confined or access-restricted job sites. Subcontractors rely on them where standard cranes cannot manoeuvre. Common in industrial shutdowns, pipeline work, and tight construction corridors.

First Gas

Industry

The milestone when a gas facility produces and delivers its first commercial volumes. For subcontractors, it signals the end of construction-phase work and the shift to operations-phase contracts. Billing terms, crew rotations, and scope of work often change significantly at this point.

Life Extension

Industry

A formal process that prolongs the operational life of ageing assets beyond their original design lifespan. For subcontractors, it often means increased inspection, repair, and maintenance scopes. Expect stricter compliance requirements and potential for longer-term service contracts.

Marine Construction

Industry

Offshore and nearshore infrastructure work including platform installation, subsea pipelines, and dock or jetty builds. Subcontractors often face strict vessel access requirements and marine safety certifications. Mobilisation costs and weather delays are major contract risk factors.
