DIVING EQUIPMENTS
20ft Diving Machinery Container
JK Subsea Engineering Pvt. Ltd. is a trusted Diving Machinery Container manufacturer and supplier, building the 20ft Diving Machinery Container, Model No. JK20FMC, for offshore projects that need more than a basic compressor setup. Built on approved ISO container and modified for diving use, this offshore diving support container splits into a dedicated machinery room and a supervision cabin, so a full compressor plant, gas storage bank, and hydraulic power unit run alongside a proper workspace for the crew, all inside one standard container footprint.
What is a 20ft Diving Machinery Container?
A 20ft diving machinery container is a purpose-built, containerized breathing air system that houses the compressors, gas storage, air filtration, and hydraulic power equipment needed to run a large commercial diving spread. Unlike a 10ft unit, which is used entirely for machinery, a 20 ft container is split into two sections: a larger machinery room for the compressors and cylinder banks and a smaller supervision cabin that doubles as a workplace for the crew. This split layout is what sets a 20ft offshore dive support container apart from a simple machinery skid, keeping noisy, high-heat equipment separated from the people running the operation, while still fitting the whole system into one standard shipping footprint that can be craned onto a vessel and connected to power in a single step.
Key Features of 20ft Diving Machinery Container
Our 20ft machinery container, also used as a containerized diving support unit, is built to run a full-scale offshore diving spread from one self-contained module.
- IMCA Compliant Design: Designed to IMCA D018 and D023 guidelines for diving plant and surface-oriented air systems.
- Dual-Section Layout: Split into a larger machinery section and a smaller supervision and workplace cabin, keeping crew space separate from compressor noise and heat, something a standalone machinery skid can’t offer.
- Fire-Retardant Insulation: Container walls are fitted with 50 mm thick fire-retardant polyurethane insulation sandwich panels.
- HP & LP Compressor Setup: Houses 1 HP compressor and 2 LP comressors, with 3 intake lines,.
- Integrated Hydraulic Power Unit: A self-contained HPU supplies hydraulic power to underwater tools and actuators, with a built-in safety package.
- 3-Stage Breathing Air Filtration: A brass manifold filter system with control valve and non-return valve delivers clean air through 6 outlet connections, 3 for the diving panel, 1 for the recompression chamber, and 2 as emergency backup.
- Ceiling-Mounted Storage Reservoir: Two 400-litre SS316L pressure reservoir tanks, connected in series, supply the diving panel and recompression chamber.
- 27-Cylinder Breathing Air Quad: A high-pressure gas distribution panel with cylinders coded separately for each diver, plus emergency capacity for twin lock chamber pressurization.
- Umbilical Frame with SS316 Hooks: Mounted on the container door to hold 150 m of 4-core diving umbilical on either side, keeping weight evenly balanced.
Applications of 20ft Diving Machinery Container
Our offshore 20ft machinery container supports large-scale breathing air and hydraulic power supply across a range of commercial diving and subsea operations.
Large Offshore Diving Spreads: Provides high-capacity compressor and gas storage for multi-diver, saturation, or long-duration surface-supplied diving projects.
Offshore Oil & Gas Projects: Keeps commercial divers supplied with air during platform inspection and maintenance work.
Recompression & Decompression Chamber Support: Feeds air directly into recompression chambers alongside the diving panel.
Underwater Tool & Actuator Power: The integrated HPU supplies hydraulic power for underwater tools during subsea operations.
Combined Machinery & Supervision Setups: The dedicated cabin section lets a supervisor manage operations from within the same container footprint.
Marine Construction & Subsea Projects: Provides a self-contained, mobile air and hydraulic power solution for offshore construction diving.
