Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

DMR (Damage Mechanism Review)

A structured engineering assessment identifying how equipment or piping could degrade, corrode, or fail. Subcontractors use DMR findings to scope inspection work and apply correct procedures. Ignoring DMR requirements can result in scope gaps, rework, or safety incidents.

Related Terms

DEF (Diesel Exhaust Fluid)

Industry

A urea-based solution injected into diesel exhaust systems to reduce harmful emissions on Tier 4 equipment. Subcontractors must keep adequate DEF on-site, as running out triggers engine derate or shutdown. Factor DEF supply and storage into your remote site logistics planning.

Extreme Value Analysis (eva)

Industry

A statistical method used to predict the likelihood of rare but severe events, such as equipment failures or extreme weather. Subcontractors use EVA to assess risk exposure and justify contingency planning in bids. It supports decisions around insurance coverage, mobilisation buffers, and site safety protocols.

MOU (Memorandum of Understanding)

Industry

A 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.

Abrasive Blasting

Industry

A surface preparation method that uses high-pressure propelled media (sand, steel grit, or slag) to clean and profile metal surfaces before coating or painting. Subcontractors performing this work typically require specialised equipment, trained operators, and site-specific permits. It is common in pipeline, vessel, and structural steel maintenance scopes.

Prefabrication

Industry

The assembly of piping, structural, or mechanical components in a controlled shop environment before site installation. Subcontractors often bid prefab scope separately from field installation work. It can reduce on-site labour hours and shorten project schedules.

Cleanout

Industry

A service job focused on removing debris, scale, or obstructions from a wellbore, tank, or pipeline. Subcontractors are often mobilised on short notice to perform cleanouts between production phases. Accurate job scoping is critical, as unforeseen material volumes can affect your quoted price.
