NG - SCG Series Marine Screw Gas Ends

Marine and offshore installations demand compressor components that can deliver stable performance under vibration, variable ambient conditions, and continuous-duty expectations. The NG–SCG Series Marine Screw Gas-ends are engineered as oil-injected screw gas ends for OEM packages that must operate reliably in harsh environments while maintaining repeatable performance across a defined operating envelope.

This series combines marine-ready construction and practical integration features—such as integrated gear-box architecture and mechanical sealing—to support packaged solutions where reliability, serviceability, and long-term value are essential.

In marine environments, durability is not optional—it is the foundation of uptime. The NG–SCG Series is designed for harsh conditions where mechanical robustness, stable operation, and long service intervals matter.

For OEMs, this matters because the gas end is the core of the compressor package. A design intended for marine duty helps reduce risk across the lifecycle—from commissioning to routine maintenance—especially when systems operate in remote or high-utilization locations.

The NG–SCG Series marine offering targets a clear pressure window for common marine gas compression duties, supporting suction pressure of 1 barg (14.5 psig) and discharge pressure up to 20 barg (290 psig), with maximum achievable flow up to 90 m³/min (3200 cfm).

Within the lineup, OEMs can select from multiple frames—such as NG 13, NG 14, NG 21, and NG 22—each providing a defined power and flow range to help scale packaged solutions for different vessel or platform requirements.

OEM engineers benefit most when a gas end supports straightforward packaging and repeatable builds. The NG–SCG Series marine gas ends are built with integration in mind, featuring integrated gearing, a mechanical seal, and a bare-shaft, single-stage, oil-injected architecture.

This approach supports practical system layouts by helping designers match speed and power transmission needs while keeping the compressor package compact and service-accessible. It also supports standardization across variants, which can reduce engineering time and improve production consistency.

Gas compression components must maintain integrity over long operating cycles—especially when applied to changing operating loads or environmental conditions. The NG–SCG Series emphasizes mechanical sealing and high-quality bearings, supporting stable operation across the intended range and helping OEMs deliver dependable packaged systems to end users.

For marine users, dependable sealing and bearing performance contributes directly to uptime, reduced unplanned maintenance, and more predictable service planning—key expectations where access and downtime can be costly.

The NG–SCG Series is built on established manufacturing know-how and field experience, supporting confidence when specifying a core compression element into a marine package—particularly when the system must perform consistently over years of operation.

Just as importantly, using a defined gas-end family in marine builds can help create a repeatable platform approach: one engineering strategy, multiple package outputs, and a clearer pathway for spares planning and service documentation.
