OTS Offshore is Vietnam’s manufacturer specializing in geotechnical equipment that operates under a fully integrated Make-to-Order (MTO) manufacturing model. From engineering and fabrication to inspection and final delivery, every stage is performed entirely in-house, ensuring quality and compliance with international standards.
What is Make-to-Order (MTO)?
In the offshore industry, every project presents unique technical requirements, including operating conditions, load capacity, dimensions, applicable standards, and environmental factors. As a result, off-the-shelf equipment cannot always meet project-specific demands.
Make-to-Order (MTO) is a manufacturing approach in which equipment is designed and fabricated only after receiving the customer’s drawings, technical specifications, and project requirements. Instead of selecting standard catalog products, customers receive a solution engineered specifically for their application.
This manufacturing model is widely adopted across the Offshore, Oil & Gas, Marine Engineering, and Heavy Industrial sectors, where customized equipment is essential for achieving reliable performance in demanding environments.
Why Does OTS Operate Under the MTO Model?

As a specialist in offshore equipment engineering and fabrication, OTS recognizes that no two projects are identical. Rather than producing standardized equipment, we manufacture each solution based on the specific technical requirements of the project.
Supported by an experienced engineering team, advanced 3D design capabilities, and manufacturing processes certified to internationally recognized standards including EN ISO 3834-2 and EN 1090-2 EXC3, OTS transforms engineering concepts into fully customized products that meet the expectations of clients in both domestic and international markets.
The Make-to-Order Process at OTS
To ensure every product meets project-specific technical requirements, OTS follows a structured Make-to-Order manufacturing process.
Technical Requirement Review
Our engineering team works closely with customers to review drawings, technical specifications, operating conditions, and project requirements.
Engineering & Design
Equipment is developed using professional 3D design software and, where required, engineering analyses are performed to evaluate structural performance before fabrication begins.
Fabrication
Machining, fabrication, and welding are carried out under controlled quality procedures by qualified personnel in accordance with project requirements.
Inspection & Acceptance
Critical components are inspected using appropriate Non-Destructive Testing (NDT) methods before final testing, acceptance, and delivery.
Throughout the entire process, manufacturing records are maintained to ensure complete quality control and product traceability.
