The project record lists two STD1400/95 marine nitrogen units with a combined design capacity of 2,800 Nm³/h.
01 / CONTEXT
The project record lists two STD1400/95 marine nitrogen units with a combined design capacity of 2,800 Nm³/h.
02 / PROBLEM
The two STD1400/95 units and their design capacity follow the existing record. Two units do not automatically provide full redundancy; verify shipboard demand. Class, location, vibration, ventilation and testing follow project documents.
Shipboard layout and documentation
03 / ENGINEERING
These are engineering considerations for this configuration. Project documents confirm the delivered scope, control design, test conditions and interface responsibilities.
The available record supports the configuration summary; no shipment date, customer acceptance or measured operating result is added here.
04 / VALUE
For a similar duty, assess supply continuity, maintenance, gas quality and total cost separately. The economic model below illustrates a calculation; it does not prove this customer’s saving or payback.

EQUIPMENT & DELIVERY
Air enters the membrane bank. Faster-permeating gases leave on the permeate side, while nitrogen-rich gas exits the product side. Flow, purity, pressure and temperature interact; filtration and feed conditions must follow the membrane supplier’s data.

EQUIPMENT & DELIVERY
A container combines equipment and interfaces in an engineered package. Check heat rejection, ventilation, drainage, noise, maintenance and electrical isolation. Transport dimensions and lifting arrangements require a separate review; this concept has no assumed dimensions.

EQUIPMENT & DELIVERY
Agree who prepares foundations, power, earthing, gas connections, drainage and maintenance access before installation. Hook-up is followed by leak checks and agreed functional tests. This is a generic installation illustration, not a customer-site record.
PROJECT RECORD
The record follows three evidence lines: configuration, manufacturing and integration, then installation and commissioning. Images come from existing equipment, integration or commissioning records; text is tied to the confirmed location, industry, model and quantity.
Engineering record
The image helps explain equipment and process interfaces. Confirm the delivered configuration, inspection and acceptance against the project’s controlled documents; a general equipment image does not supply missing project facts.

PROJECT DELIVERY
Technical boundaries, delivery responsibilities and acceptance criteria are defined early to prevent interface rework on site.
Confirm flow, purity, pressure, dew point, operating hours, peaks and current gas cost.
Define scope, select equipment, model energy use and support technical tender documents.
Confirm utilities, interfaces, controls, safety interlocks, civil works and piping.
Build to controlled drawings and inspect key components, assembly, leakage, electrical and performance.
Coordinate packing, transport, lifting, piping, power and site readiness.
Complete checks, integrated start-up, purity and flow verification, training and acceptance records.
Track operating data and maintenance, with one-year contractual warranty and remote support.
ECONOMICS
Model, quantity and design capacity come from the project record. The table uses only the provided RMB 0.35/m³ on-site cost and RMB 0.90–1.20/m³ delivered price to calculate an auditable annual cost spread.
| Delivered unit price | Annual delivered cost | Annual on-site cost | Annual cost spread |
|---|---|---|---|
| RMB 0.90 / m³ | RMB 11,466,000 | RMB 4,459,000 | RMB 7,007,000 |
| RMB 1.05 / m³Midpoint scenario | RMB 13,377,000 | RMB 4,459,000 | RMB 8,918,000 |
| RMB 1.20 / m³ | RMB 15,288,000 | RMB 4,459,000 | RMB 10,829,000 |
FORMULA
Contract value and actual customer gas bills are not public, so this page does not invent investment, payback or ROI. Provide total investment, local power price, operating hours and maintenance budget for a formal calculation.
Illustrative model: RMB 0.35/m³ and RMB 0.90–1.20/m³ are reference inputs, not this customer’s bills. Load and hours are assumptions. Identify energy and maintenance already included in the on-site rate before deducting additional costs. Use the same volume basis; overseas projects require local prices and currency.
