Assembling a 4,500T Chemical Tanker with <0.2mm Precision Using KIET's 3D Adjustment Hydraulic Equipment

2026-04-20

Summary

To facilitate the construction of a new 4,500T chemical tanker, KIET provided the client with four PLC-controlled, 200-ton 3D Adjustment Hydraulic Equipment, successfully solving the critical challenge of high-precision hull block joining.

The Challenge

Four KIET 3D adjustment hydraulic equipments working in synchronization to align hull blocks, with engineers supervising the process.

The primary challenge was the assembly of a new 4,500-ton chemical tanker, a vessel type that demands exceptional structural integrity and adherence to strict safety standards. The client needed a method to join massive, 200-ton hull blocks with a precision under 0.2mm to ensure a flawless and efficient construction process for this specific vessel.

The Solution

A single 200-ton KIET hydraulic adjustment unit positioned under the steel structure of a ship's hull during assembly.

KIET engineered and delivered a turnkey solution featuring four heavy-duty 3D Adjustment Hydraulic Equipments, specifically configured for the chemical tanker assembly line. Key features of the solution included:

Operators at a shipyard maneuvers a KIET 3D hydraulic adjustment unit into the precise lifting position under a large ship hull block.

PLC Computer Control

A sophisticated, centralized system for synchronized and precise operation.

200-Ton Lifting Capacity

Robust power to handle the large-scale hull segments of the 4,500T vessel.

3-Axis (X, Y, Z) Adjustment

Fine-tuned directional control for perfect alignment.

The Result

The implementation of KIET's systems was a resounding success for the chemical tanker project. The primary goal of achieving a positioning accuracy of less than 0.2mm was consistently met, a critical benchmark for quality in modern shipbuilding.
