Heavy-Duty Modular Drawer Cabinets for Marine Use - Installed on an Ocean-Going Oil Tanker

This project was developed for a Nordic shipping company during the construction of its new cargo vessel fleet. Once completed, the vessels would be used for ocean-going freight transportation, requiring reliable onboard storage for tools, spare parts, maintenance supplies, and other operational items. 

Unlike storage cabinets used in land-based workshops, shipboard cabinets must operate in a constantly moving environment. Rolling, vibration, vessel inclination, and harsh sea conditions can create serious safety risks if drawers slide out unexpectedly, stored items fall, or cabinet structures deform during operation. 

For this project, the customer required a reinforced modular drawer cabinet solution that could keep tools and parts organized while protecting crew members inside the vessel. The cabinets had to remain stable and functional under demanding marine conditions, prevent accidental drawer movement, and reduce the risk of impact, falling objects, or personnel injury during onboard operation. 

The customer name and vessel name are not disclosed due to project confidentiality. 

The project had two critical requirements: stable operation under vessel inclination and secure installation inside the cabin. Both requirements were directly related to onboard safety, because any cabinet movement, structural deformation, or accidental drawer opening could create risks for crew members. 

The most important requirement was that the cabinets had to remain stable and functional under a 30° vessel inclination. In harsh sea conditions, cabinets are exposed not only to vertical load, but also to lateral forces caused by vessel rolling, vibration, and sudden movement. 

If a cabinet deforms or tilts, the stored tools, spare parts, and maintenance supplies may fall out and create a safety hazard. If drawers slide out unintentionally during vessel inclination, the drawer itself and the items stored inside may injure crew members working nearby.

To address this challenge, the cabinet structure needed to be reinforced for shipboard use. The drawer retention system also became a key part of the safety design. Each drawer had to remain closed during vessel movement and could only be opened intentionally by the operator. Since the customer did not require an interlocking system, the drawer safety catch became even more important to prevent accidental sliding while still allowing fast access to multiple drawers when needed. 

The second major requirement was secure cabin installation. Unlike a standard workshop floor, a vessel cabin has limited space, fixed interior structures, and operating conditions that involve continuous movement. The modular drawer cabinets could not simply be placed inside the cabin like ordinary workshop furniture. 

The cabinet base and overall installation method had to be customized according to the customer’s cabin layout and installation requirements. The goal was to keep the cabinets properly positioned during vessel movement and reduce the risk of tilting and displacement.

To meet the customer's shipboard storage requirements, ROCKBEN customized a reinforced modular drawer cabinet solution specifically for the vessel cabin environment. The solution focused on three key areas: cabinet structural strength, drawer safety retention, and secure onboard installation. 

For this project, ROCKBEN used thicker steel plates to customize a reinforced frame and support structure for the cabinet body. Compared with standard workshop cabinets, the reinforced structure was designed to improve overall rigidity and reduce the risk of deformation when the vessel is exposed to rolling, vibration, and inclination during operation. 

In our standard industrial cabinet design, the cabinet body panels usually start from 1.0 mm thick steel, while the main supporting components are typically made from 1.2–1.5 mm thick steel, depending on the structure and load requirements.

For this oil tanker project, we increased the material specification to improve rigidity. The cabinet body panels were upgraded to 1.2 mm thick steel. All major weight-supporting structures, including the support columns and reinforced beams, were made from 1.5 mm thick steel. The cabinet base was mde with 2.0 mm thick steel to support stable installation inside the vessel cabin.

Each drawer was equipped with a safety catch to prevent accidental opening during vessel movement. This was one of the most important safety features of the project, because drawers sliding out under vessel inclination could cause stored parts and tools to fall out of the cabinet. 

To verify drawer retention, ROCKBEN conducted a practical 30° inclination test when the customer visited our factory in Shanghai for sample inspection. The cabinet was manually tilted in front of the customer to simulate the vessel inclination requirement. During the test, the drawers remained closed and did not slide out unintentionally, helping confirm that the reinforced safety catch structure could support the customer's requirement for shipboard use. 

The customer also required fast access to stored items during emergency. For this reason, the cabinets were designed without an interlocking system, allowing multiple drawers to be opened at a time. Because the interlocking system was not used, ROCKBEN further reinforced the safety catch installation structure to reduce the risk of accidental drawer movement while maintaining fast manual access. 

Cabin installation was another key part of the solution. The cabinets could not simply be placed inside the vessel like ordinary workshop furniture. They needed to remain properly positioned during vessel movement and fit the actual installation conditions inside the cabin. 

ROCKBEN customized the cabinet base according to the customer's requirements, including raising the base height and modifying the base design for the vessel cabin layout. After production, ROCKBEN also provided onboard installation service for the customer. Our team went onto the vessel to support the final installation, helping ensure that the cabinets were properly positioned and installed according to the project requirements. 

A standard workshop cabinet is usually designed for stable indoor floors, predictable loading conditions, and normal daily use. This oil tanker project required a different level of engineering consideration.

On a vessel, cabinets must perform in a moving environment where rolling, vibration, and inclination can affect both the cabinet structure and the stored items inside. If the cabinet body deforms, the base becomes unstable, or drawers slide out unintentionally, the result is not only storage failure but also a potential safety risk for crew members.

For this reason, the solution had to go beyond standard workshop storage. ROCKBEN reinforced the cabinet body, upgraded key supporting structures, strengthened the drawer safety catch system, and customized the raised installation base for the vessel cabin. The final design was developed to keep tools, spare parts, and onboard supplies organized, accessible, and better protected under harsh marine operating conditions.

This project shows how industrial storage equipment must be adapted to the actual working environment. For shipboard applications, strength, safety, and installation reliability are just as important as storage capacity. 

A modular drawer cabinet, also known as Industrial drawer cabinet or industrial tool cabinet, is an industrial storage cabinet designed with multiple drawers for organizing tools, spare parts, components, and maintenance supplies. Compared with simple shelving, drawer cabinets provide higher storage density, better item classification, and easier access to small or medium-sized parts.

The modular design allows the cabinet to be configured with different drawer heights, layouts, dividers, colors, load capacities, and installation options according to the user’s working environment.

Yes. Modular drawer cabinets can be used on ships, oil tankers, cargo vessels, and other marine environments when the cabinet structure, drawer retention system, and installation base are designed for onboard operating conditions.

Yes. ROCKBEN can customize modular drawer cabinets and storage solutions according to your actual production environment, storage items, load requirements, available space, and operating conditions.

Different industries and applications often require different cabinet structures, drawer layouts, accessories, and installation methods. To develop a suitable solution, you can share your application, installation space, stored items, required drawer load, working environment, and any special safety or access requirements. ROCKBEN will configure the cabinet design based on your needs.
