Modular Skids
KEY ADVANTAGES
Why modular skid-mounted construction outperforms stick-built
FASTER DELIVERY
Parallel fabrication: modules are built and tested in the shop while site preparation continues.
CONTROLLED QUALITY
Indoor welding and NDT in a clean, climate-controlled environment. Consistent quality every unit.
PLUG & PLAY
Minimal on-site hookup required. Factory-tested modules arrive ready for connection at battery limits.
SAFETY FIRST
Reduces hazardous field man-hours. Less on-site hot work means fewer safety incidents.

TWO KINDS OF SKID WORK
Say in your RFQ which one applies — it decides who owns the design and the performance.
- Packages we design. Industrial refrigeration units and gas compressor packages: process, mechanical, structural and control design by Lmart, compressor bought in, after-sales support in China. Examples: 8 BOG compression units for PIL’s 14,000 TEU LNG dual-fuel container ships (ABS, 2023) and 19 propylene refrigeration compressor packages for VLEC and ULEC newbuilds (ABS, 2024–2025).
- Skids we build to your design. Marine fuel gas and cargo-handling skids, offshore process skids, filter packages, and labyrinth compressor skids built around Burckhardt Compression machines. The process design stays with the system owner; we build, test and document the skid.
CLASS-APPROVED SKIDS
DNV, ABS, NK, LR, BV and CCS class projects on our reference list
Each marine skid is surveyed under the classification society named in its project: drawing review, welding procedure and welder approval under that society, NDE to its rules and witnessed pressure tests. Skids on our reference list have been built under ABS, BV, CCS, DNV, LR and NK class. If you need DNV-classed or ABS-classed skids, ask for the project references under your society rather than a certificate list.

FREQUENTLY ASKED QUESTIONS
Common questions about modular skid-mounted packages
What types of equipment can be integrated into a modular skid?
We integrate a wide range of process equipment onto modular skids: Lmart-designed refrigeration and gas compressor packages (oil-injected screw), skids built around another supplier’s compressor such as Burckhardt labyrinth compressors, refrigeration systems, heat exchanger assemblies, pump stations, chemical injection systems, metering skids, and utility distribution modules. The key requirement is that the process can be factory-assembled, tested, and transported as a self-contained unit.
What are the size and weight limits for skid-mounted packages?
Standard road-transportable skids: up to 3.5m (W) × 4.5m (H) × 15m (L), with weights up to 40 tonnes. For larger assemblies, we design modular split-skids that bolt together on site. Oversize loads can be shipped via specialized transport or sea freight — we handle logistics planning as part of the project scope.
What are the advantages of skid-mounted vs. field-erected equipment?
Skid mounting moves fabrication from site into the shop, improves quality control (factory environment vs. field conditions), enables full FAT before shipment, and reduces site safety incidents. The trade-off is transport size constraints and potentially higher upfront engineering cost, which is offset by faster time-to-production.
What standards do your skid packages comply with?
Structural steel: AISC/ASCE or EN 1993. Pressure equipment: ASME BPVC or PED 2014/68/EU. Piping: ASME B31.3. Electrical: IEC 61892 (offshore), IEC 60079 (hazardous areas), NEC/CEC (North America). We also build to project-specific specifications and to the classification rules named in each marine or offshore project; our reference list includes skids under ABS, BV, CCS, DNV, LR and NK class.
Do you handle piping, electrical, and instrumentation integration?
Yes. Our scope includes mechanical assembly, process piping (welded and flanged), instrument tubing, cable routing and termination, junction boxes, and local control panels. We deliver a fully tested, ready-to-connect module. The scope boundary between our supply and client/EPC scope is defined in the battery limits document at project kickoff.
What testing is performed before shipment?
All skids undergo: hydrostatic/pneumatic pressure testing per code, piping leak testing, electrical continuity and insulation testing, instrument loop checks, and a full Factory Acceptance Test (FAT). For compressor and pump skids, mechanical running tests are added where the specification calls for them. FAT protocols are agreed with the client before execution, and third-party witness inspection is available.
