Short Answer

Before requesting an offshore workshop-container quotation, define the work to be performed inside, the equipment and storage required, the installation environment, applicable certification, utility interfaces, safety systems, transport limits and required documentation.


The most effective enquiries do not begin with “Please quote a 20ft workshop container.” They explain the operating task, because that task determines the layout, floor loading, HVAC, power, lifting, fire protection and certification package.


What Is an Offshore Workshop Container?

An offshore workshop container is a transportable, purpose-built workspace for maintenance, repair, inspection or specialist support work on an offshore installation, vessel or marine project. It may contain workbenches, vices, shelving, tool storage, lifting aids, electrical outlets, compressed-air connections, HVAC, lighting and safety equipment.


Depending on the project, the unit can be engineered as an offshore container to DNV 2.7-1 and EN 12079 requirements, a fire-rated module, or a hazardous-area-compatible workspace. Those scopes must be specified rather than presumed.


Start With the Work Scope

Describe the actual workshop activity: mechanical repair, electrical maintenance, hydraulic work, calibration, welding preparation, ROV support, rigging, instrument repair or another task. Then identify whether it involves sparks, hot work, chemicals, lifting, compressed gas, batteries or oil.


This information drives practical decisions such as:

  • bench dimensions and vice locations;
  • storage for tools, spares and consumables;
  • floor load capacity and tie-down points;
  • extraction, ventilation and filtration;
  • electrical outlet ratings and distribution;
  • fire detection, suppression and emergency isolation; and
  • hazardous-area controls or segregation.


The Quotation Checklist

1. Layout, dimensions and access

Provide a preferred size or footprint, but also supply the required working area, equipment list and access limitations. Define door positions, personnel access, equipment-loading routes, crane or forklift handling constraints and clearances around workstations.


2. Equipment, payload and floor loads

List all supplied or customer-furnished equipment with its weight, footprint, heat output and fixing arrangement. Include heaviest lift, stored-spares weight, point loads, dynamic loads and any internal lifting beam, hoist or crane requirement.


3. Offshore structure and lifting

State whether the workshop will be transported or lifted offshore, and identify required standards such as DNV 2.7-1 and EN 12079. Provide maximum gross mass, lifting method, deck installation details, sea fastening, stacking restrictions and any client or class requirements.


4. Environmental conditions and corrosion protection

Define the installation region, minimum and maximum ambient temperatures, humidity, salt spray, wind, solar load and corrosivity requirements. These inputs affect coating selection, insulation, HVAC sizing, weather seals and the selection of external equipment.


5. Electrical and utility interfaces

Specify incoming voltage, frequency, available power, fault level, earthing arrangement, plug or gland type, lighting requirements and socket standards. State whether the workshop needs compressed air, water, drainage, network, telephone, welding power or other utilities.


6. HVAC and ventilation

Identify occupancy, equipment heat loads, required internal conditions and any contaminant source. A workshop that uses solvents, battery charging or process chemicals may need local extraction or an engineered ventilation arrangement in addition to general cooling.


7. Fire and hazardous-area requirements

Provide the hazardous-area classification, fire rating, detection requirements, gas hazards and host-system interfaces. Hot-work activities or flammable materials can change the required safety concept. A standard workshop layout should not be used for a hazardous location without an appropriate engineering review.


8. Documents, inspection and delivery

Specify required drawings, calculations, material certificates, inspection and test plan, load-test records, NDT reports, coating reports, certificates, FAT attendance, packing requirements and delivery port or site.


Frequently Asked Questions


Is a workshop container just an equipment container with benches?

No. A functional workshop must safely support the specific work, personnel, tools and utilities involved. The correct design considers workspace, storage, loads, maintenance, ventilation, electrical safety, fire risk and installation interfaces as an integrated package.


Can a workshop container be installed in a hazardous area?

Possibly, but the hazardous-area classification and work activities must be assessed first. The final solution may require pressurisation, Ex-rated equipment, gas detection, extraction, fire protection, operating restrictions or a different installation location.


Should I request A-60 fire protection?

Only when the project fire-safety plan or client specification requires it. If needed, the required fire-rated boundary and all relevant doors, penetrations, ventilation dampers and interfaces must be defined.


What is the fastest way to receive an accurate quotation?

Send a simple equipment list, preferred layout, certification requirements, utility schedule, target delivery date and installation details. Even a marked-up sketch and photographs of similar equipment can significantly improve the initial technical review.
