Please leave plant design and piping 3DCAD design to us

“TSUBASA ENGINEERING SERVICE Co.,Ltd.” is a plant engineering professional manufacturer located in Kitakyushu, Fukuoka Prefecture. Our service is a comprehensive engineering from various plant design and piping design to construction planning and management, about petroleum, chemical, steel, electricity, environment, air conditioning, water supply, drainage, recycling, marine resources, etc.
On this page, we introduce our main design results.



On conventional design sites, drawing by handwriting or 2DCAD was common.
However, designing a three-dimensional structure based on a plan view tends to cause errors at the stage of combination, and there are various disadvantages such as difficulty in imagining a completed figure from the drawings.

In order to solve this problem, we introduce 3D design by 3DCAD at our design site.
Expressing stereoscopically by adding detail data such as depth and height, as well as thickness, we achieve high accuracy and high quality drawing design with no error.

In addition, it is also a big merit of 3D design by 3DCAD that it is easy to share the finished image with customers by visually representing the completed model.

Technical analysis

Technical analysis

In the current technical analysis, if we do not even mistake the numerical input, the software automatically calculates, and an accurate conclusion can be obtained.
However, if the person in charge complete calculating without noticing input mistake, there is a risk of designing plant and piping based on conclusions different from actual condition.

With a thorough system to be evaluated by experienced engineers and utilizing the latest software, we provide high safety and reliability technical analysis.

Our engineers in charge of analysis are specialists in technical analysis who are familiar with not only basic and applied engineering but also thermodynamics, material mechanics and fluid dynamics.
It is applicable to technical analysis in all fields including application analysis, fluid analysis, structural analysis, heat transfer analysis, earthquake resistance analysis and so on.

Our Flowchart

Basic Design (Planning Design)

Based on the plan customers sumitted to us, we take consistency in the whole plan so that it meets the requested specifications.
We determine the terms of the basic design, analyze and examine and design process functions.
By doing basic design of piping and various equipment, we decide necessary matters for detailed design.

Detail Design

Based on the basic design, detailed desgin leading to procurement, construction and operation is carried out.
Also, 3 dimentional design by 3DCAD is carried out in this step.

In addition, by utilizing the latest analytical tools and simulation tools to perform structure and strength calculations and analysis work, professionals in each field demonstrate their expertise to add concrete and precise details to the plant only on data.

Procurement (Material purchasing assistance)

Based on detailed design, We purchase equipments and materials necessary for construction of the plant, and conduct inspection and transportation, etc., respectively.
We support all kinds of work related to material selection and procurement including preparation of purchase specifications, quotation inquiries etc.

Construction (Construction management)

Construction is carried out based on specifications determined so far.
We also accept temporary dispatch of managers who manage the entire construction such as construction period, cost, quality and safety, etc.
From construction planning and construction management to construction and trial operation, we dispatch experienced personnel to provide safe and secure service.
