Meta description: An MCC pressurised cabin houses motor controls, switchgear and drives in a protected workspace for offshore and industrial applications.
An MCC pressurised cabin is a containerised room that houses electrical control equipment in offshore and industrial environments. It combines a protective enclosure with systems that help maintain suitable conditions for the equipment inside.
MCC stands for Motor Control Centre. It controls and protects electric motors used to operate equipment such as pumps and fans. An MCC cabin can also accommodate switchgear, control panels and motor drives, depending on the project.
Why Put Electrical Controls Inside a Cabin?
Electrical equipment needs protection from its surroundings. On an offshore installation, rain, salt-laden air and changing weather can make an exposed location unsuitable for sensitive controls.
A dedicated cabin brings the equipment into an enclosed workspace. It also gives personnel somewhere to read displays, check panels and carry out planned maintenance.
For example, a project operating several motor-driven pumps may need a central location for their controls. An MCC cabin can house those controls together, with access arranged for the people responsible for operating and maintaining them.
What Does Pressurisation Do?
Some sites also need protection against potentially flammable gases outside the cabin.
In simple terms, pressurisation uses a controlled supply of air to maintain a higher pressure inside the room than outside. When correctly designed and operated, this helps limit the entry of the surrounding atmosphere.
The pressurisation system works alongside monitoring and protective controls. If the required conditions are lost, the system follows the alarm or protective response defined for the project.
Pressurisation and air conditioning have different roles: one supports the cabin’s protection arrangement, while the other manages the indoor temperature. Both need to suit the equipment and location.
What Can Be Included in a TLS MCC Cabin?
TLS MCC cabins can be configured around the equipment and the way the room will be used. Depending on the agreed scope, features can include:
- Space for MCC panels, switchgear and motor drives.
- Air conditioning, ventilation and pressurisation.
- Fire and gas detection.
- Lighting, sockets and electrical cabling.
- Access doors and emergency escape provisions.
- Fire-rated construction where required.
The combination is selected for the project. Features such as A60 fire protection and hazardous-area suitability should be confirmed for the actual cabin configuration. TLS pressurised container solutions
Where Can These Cabins Be Used?
MCC cabins can support offshore installations and industrial projects that need a dedicated room for electrical controls.
The appropriate arrangement depends on the location. A cabin in a designated safe area may have different protection requirements from one installed in a hazardous area. Equipment size, operating conditions and maintenance needs also influence the final configuration.
The containerised format allows the room to be manufactured and fitted out before delivery. Site connections and commissioning still need to be completed according to the project scope.
FAQ
Is an MCC cabin the same as an MCC panel?
No. The MCC panel controls and protects motors. The cabin is the room that houses it and any other specified equipment.
Does every MCC cabin need pressurisation?
No. The required protection depends on the installation location and project assessment.
Are all TLS MCC cabins supplied with the same certification?
No. Applicable standards and certification scope are confirmed for the project.
