Switchgear

A written commitment from a client indicating they plan to award a subcontractor a contract. It allows work or mobilisation to begin before the formal contract is signed. LOIs are not always legally binding, so subcontractors should clarify payment obligations before proceeding.

A floating offshore structure anchored by a deep vertical cylinder, used in deepwater oil and gas production. Subcontractors access it by crew boat or helicopter for maintenance, inspection, and equipment services. Mobilisation costs and offshore scheduling are key considerations when bidding work on spars.

A formal process where a client or prime contractor solicits bids from multiple subcontractors for a defined scope of work. Subcontractors submit priced proposals and are evaluated on cost, capability, and safety record. Winning a competitive tender typically requires balancing competitive pricing against maintaining viable margins.

A growth phase where an operator scales up gas compression infrastructure, creating demand for additional field service crews and equipment. Subcontractors should anticipate increased work orders for installation, commissioning, and maintenance. Securing standing agreements before expansion begins helps lock in preferred vendor status.

A downhole operation to remove debris, scale, cement, or fill from inside a wellbore. Subcontractors typically provide coiled tubing, fluid pumping, or snubbing crews for this work. Scope can expand quickly, so confirm day-rate terms and standby provisions before mobilising.

Raw, unprocessed natural gas delivered to a processing plant or facility as the primary input. For subcontractors, feed gas specifications determine the scope of compression, treating, and handling work on site. Changes in feed gas composition can trigger scope variations and affect your contract terms.
