MOC (Management of Change)
Related Terms
Sanctions Compliance
ComplianceThe process of ensuring your company does not do business with individuals, entities, or countries under government-imposed trade restrictions. Subcontractors must screen clients, vendors, and partners against sanctions lists before signing contracts. Non-compliance can result in heavy fines, contract termination, or criminal liability.
Personnel Moc (management of Change)
ComplianceA formal process operators use when key personnel on a project are swapped out or replaced. Subcontractors must often submit documentation and get approval before substituting workers mid-contract. Failing to follow this process can result in work stoppages or contract penalties.
BOEM (Bureau of Ocean Energy Management)
ComplianceThe U.S. federal agency overseeing offshore energy leasing on the Outer Continental Shelf. Subcontractors working U.S. offshore projects must meet BOEM-driven compliance requirements set by their prime contractors. Permits and operational approvals from BOEM directly affect project timelines and mobilisation schedules.
Hazard Orientation
ComplianceA mandatory site-specific safety briefing required before subcontractor crews begin work on a new location. It covers site-specific risks, emergency procedures, and restricted zones. Primes or operators typically deliver it, and subcontractors must document attendance for compliance.
Pre-Filing Waiver
ComplianceA written agreement where a subcontractor gives up the right to file a builders' or mechanics' lien before work begins. General contractors or owners often require it as a condition of awarding a contract. Review carefully — signing one limits your legal options if payment disputes arise.
