Supply Chain Services are aimed at ensuring that during the procurement phase, your vendors and suppliers will deliver the desired level of quality, required compliance to standards and will do so in an efficient and timely manner.

Any purchase carries embedded risk. In most industrial sectors, large construction projects involve the purchase of a vast number of items supplied by various manufacturers. Quality and safety are a priority for these projects. Therefore, it is of vital importance to check the quality of every single item, no matter how small. These components range from raw materials to finished products.

The main activity is the supply of desk, shop, and/or project site inspection or expediting services to the Oil & Gas, Petro Chemical, Power Generation, Mining, Transportation, Process, Marine and other such industries.

We can provide

Vendor Shop Inspection

Vendor Shop Inspection

Shop Inspection involves inspecting items at their place of manufacture before delivery. This is the most convenient and cost-effective way to determine whether a product, service, process, piece of equipment or installation complies with expressed needs, customer expectations, applicable regulations, standards or other specific requirements. Shop inspection can include design review, review of material certificates, visual inspection, Non Destructive Testing (NDT), attendance, supervision or performance of mechanical or functional tests. Often can also include witnessing of final reception testing.

Key Benfits
  • Risks linked to Quality and safety problems with supplies can be avoided.
  • Independent assessments provide reassurance.
  • Detailed reports and certificates secures confidence in using supplied items.
  • Services are a cost effective solution to verifying the Quality Assurance/Quality Control organizations of suppliers.
  • Skilled personnel with relevant experience and qualifications are at your service.
Site inspection

Site inspection

Once the equipment is delivered to site, OCA Group supervises the different construction, installation and commissioning aspects to ensure that the asset is properly installed, and is capable of operating within the safety Conditions determined by the client's Specifications, local and International codes and government guidelines.



This service appears with the need of the purchasing department to monitor the progress of manufacturing in relation to quantity, quality, packaging, compliance with standards, deadlines and delivery place.

Expediting, therefore, is one of the major activities contributing to the successful execution of major projects; it enables the site construction work to proceed as scheduled and helps to minimize delays and costly product deficiency issues. In those large-scale projects, such as refineries or power plants, delay caused by late delivery or low quality grade can represent an incalculable cost impact on the project.

Expediting requires detailed and quantified analysis of causes and effects throughout the critical path of fabrication of a given piece of equipment, from ordering to delivery. This includes Order (or procurement) status and Delivery Schedules; Inventory of equipment in stock; Design verifications; Progress in Manufacturing, Testing, Packing, Shipment and Delivery. Our inspection personnel manage all the quality activities relating to equipment, materials and commodities in order to ensure that vendors’ obligations meet Purchase Order requirements and contractual delivery terms.

Our expeditors always provide real-time and transparent data to our clients and verify that purchasing specifications have been properly understood and applied on-site.

Correct implementation of vendor expediting is essential for construction planning as timely delivery of equipment and materials reduces potential penalties in not meeting construction completion dates. Our expeditors conduct physical verification of the vendor’s progress against identified milestones to assure completion is in line with the production plan. OCA International has a wide international inspectors network facilitating the coordination of global expediting activities. Our expediting experts support projects within the following industries:

  • Oil & Gas
  • Power & Utilities
  • Wind Energy
  • Solar Energy
  • Infrastructure
