A large lifting crane mounted on tracked undercarriage, used for heavy lifts on unstable or soft ground at oil and gas and construction sites. Subcontractors often source these through specialised rigging firms on a day-rate or project basis. Confirm ground-bearing capacity and operator certifications before mobilising.
Crawler Crane
Related Terms
Telematics
IndustryA system that tracks vehicle and equipment location, usage, and performance data in real time. Subcontractors use it to monitor fleet activity, verify hours worked, and support billing accuracy. It also aids compliance with safety and maintenance requirements.
Lean Construction
IndustryA project delivery approach that eliminates wasted time, materials, and labour on job sites. Subcontractors use lean methods to tighten scheduling, reduce idle crew time, and improve handoffs between trades. It often involves short-interval planning tools like the Last Planner System.
Pipeline Integrity
IndustryThe ongoing process of ensuring pipelines remain safe, structurally sound, and compliant with regulatory standards. Subcontractors are frequently hired for inspection, maintenance, and repair work tied to integrity programmes. Scopes can include ILI (Inline Inspection), coating repairs, hydrotesting, and fitness-for-service assessments.
Tubular Management Services
IndustryThe tracking, inspection, storage, and handling of oilfield pipe and casing on behalf of operators or drilling contractors. Subcontractors providing these services manage inventory, thread protection, and condition reporting at wellsite or yard facilities. Scope often includes running tally sheets, third-party inspections, and coordinating pipe delivery to rig floor.
Core Desorption
IndustryA lab process where gas is measured as it releases from rock core samples pulled during drilling. Subcontractors handling or transporting cores must follow strict protocols to preserve sample integrity. Mishandling can compromise data and trigger costly disputes with operators.
MOU (Memorandum of Understanding)
IndustryA non-binding agreement outlining the intent to work together before a formal contract is signed. Subcontractors use MOUs to secure preferred vendor status or reserve capacity for upcoming projects. They carry no payment guarantee, so avoid mobilising resources based solely on an MOU.
