MacGregor Crane Spares: Sourcing Complete Crane Refurbishment Equipment from China — A Bangladeshi Shipyard Buyer's Practical Guide

The complete-package BOM (redacted, verbatim)

Below is the buyer's inquiry list, reproduced in their order of mention. The fact that they listed assemblies (not individual parts) signals an experienced procurement team who already knows what a complete refurbishment looks like.

• Main motors — quantity TBC based on per-crane specification
• 3-split gearboxes — full assembly replacement
• Hydraulic pumps — main hoist + luffing + slewing pumps
• Servo valves — for proportional control
• Hydraulic motors — hoist and luffing drive motors
• Winches — complete drum-and-frame replacement option
• Slew bearings — typically the highest-cost single line
• Control boards / PLCs — for electronic overhaul
• Other associated spares — to be specified after technical site survey

Each line above is itself a multi-component assembly — a single "hydraulic pump" line could mean 2-6 distinct pumps depending on the crane's circuit design. The supplier's first job is to convert the inquiry into a line-item schedule with part numbers and quantities.

Why the "complete package" framing matters in Bangladesh

Chittagong has its own marine procurement quirks that shape how this inquiry should be answered:

1. Customs valuation is per consignment

Bangladesh Customs values each consignment as a unit. Importing a complete crane refurbishment package as one consolidated shipment is duty-efficient compared to multiple shipments of individual parts — fewer separate customs files, single freight cost, single insurance policy. The procurement team is implicitly optimising the import economics.

2. Class society timing

If either crane operates on a class-surveyed vessel, the class society (BV, Lloyd's, DNV, ABS, NK, KR) typically requires its surveyor to be present during major equipment installation. Coordinating one supplier's complete installation visit is dramatically easier than coordinating around several individual parts arriving on different dates.

3. Local commissioning labour

Chittagong has skilled marine mechanics but limited specialist hydraulic technicians. A complete-package supplier who sends a commissioning engineer for both cranes pays off enormously — the visiting engineer can train local staff, document the install, and leave the shipyard with operational know-how for future routine maintenance.

What "complete equipment supplier" really means

Several Chinese suppliers can quote individual MacGregor parts. Far fewer can credibly deliver an entire crane's worth of equipment to consistent quality. The qualifying criteria:

1. In-house remanufacturing for major rotating equipment

The supplier should remanufacture or build the high-value rotating items (gearboxes, large hydraulic pumps, hydraulic motors) themselves — not just resell them. Trading firms cannot guarantee delivery dates or quality. The serious remanufacturers run their own machine shop, hydraulic test bench, and final assembly line.

2. Documented marine track record

Marine equipment ages badly without seawater-grade specification. Ask for: photo evidence of previous marine deliveries (preferably to South Asia), the customer references that will speak to follow-up service quality, and the supplier's standard packaging spec for marine shipment (sea worthy crating, VCI corrosion inhibitor, desiccant).

3. Capability to ship "ready to install"

A serious complete-equipment supplier ships pre-assembled major assemblies (gearbox with reservoir, hydraulic power unit complete with manifold and accumulator), individually packed with installation drawings and a recommended installation sequence. That's the difference between 4 days of installation work and 4 weeks.

How to compare complete-equipment quotes

When all three suppliers say "we'll provide everything," the quote comparison is no longer about price — it's about scope completeness. The matrix:

Scope completeness checks

• Per-assembly line-item breakdown — verify every BOM line has a part number, quantity, and unit price. A blanket "complete refurbishment package $X" hides scope gaps.
• Installation hardware included? — gaskets, hoses, fasteners, hydraulic fluid, jointing compound. Often "forgotten" until the parts arrive.
• Class society documentation — material certificates (EN 10204 3.1) for pressure parts, hydraulic test certificates, dimensional inspection reports.
• Spare parts package — what wear-parts ship with the order (seal kits, sacrificial gasket sets)?
• Commissioning support — what's included? Is the engineer's airfare to Chittagong covered? Hotel? How many days of on-site support?
• Warranty terms — 12 months from commissioning is standard for premium suppliers; many cheap quotes are 6 months from shipment (which is much weaker).

Things that should be transparent in every quote

• Lead time per major assembly (gearboxes are usually the long-lead item, 8-16 weeks)
• Payment terms — typical structure is 30% advance, 60% on factory acceptance test (FAT), 10% on commissioning
• Shipment terms — FOB Shanghai vs CFR Chittagong vs DDP shipyard (each shifts cost and risk differently)
• Pre-shipment inspection rights — buyer should reserve the right to inspect at factory before shipment

What to confirm before issuing a PO

1. Technical site survey first — the supplier should send (or accept) a technical site visit to verify each crane's actual configuration. Drawings from MacGregor headquarters are often out of date for cranes that have been modified during their service life.
2. Class survey alignment — if either crane is class-surveyed, get the class surveyor's input on acceptable supplier and on inspection points during manufacture.
3. Pre-shipment FAT — for major rotating equipment, run a factory acceptance test with the buyer (or buyer's agent) witnessing. Saves 80% of post-installation surprises.
4. Documentation pack — agree the complete documentation set in advance (operation manuals, installation drawings, parts manuals, electrical schematics, hydraulic schematics, calibration certificates).
5. Spare parts stock — order critical spare parts (seal kits, gaskets, sensors) with the original shipment. Replenishing a single seal kit later costs more than the kit itself in shipping and time.

Bangladesh marine sourcing logistics

Chittagong port handles the bulk of Bangladesh's marine equipment imports. Practical notes from past projects:

• Sea freight: Shanghai → Chittagong is 14-18 days regular service; Ningbo and Qingdao similar. Major equipment ships as break-bulk or in containers; very large assemblies (large slew bearings, full HPU skids) may need RoRo or specialised heavy-lift service.
• Customs: Marine-equipment imports for shipyard refurbishment generally qualify for capital-equipment duty treatment, but the documentation must be precise. Bangladesh Customs queries are usually about HS code classification — settle these before shipment.
• Inland transport: from Chittagong port to most local shipyards is within 30 km. Heavy assemblies need cranage at both ends. Plan the receiving cranage capacity before the supplier confirms shipment.
• Pre-shipment inspection: Bangladesh sometimes requires PSI certification for capital equipment imports. Coordinate the PSI agent (typical: SGS, Intertek, BV) before equipment is sealed in the supplier's factory.

Frequently asked questions

Closing thought

The Bangladeshi inquiry was framed as "complete equipment, two cranes." That phrasing rewards a supplier who has the depth to deliver the full scope and the discipline to document it. A bottom-priced quote that's actually a stitched-together assembly of multiple sub-suppliers will look attractive on day one and very expensive by month six. Procurement teams who've been through a few of these projects already know that — which is exactly why the inquiry came in as a single-source bid request.

How to compare quotes when they all say "100% OEM-compatible"

Every Chinese hydraulic remanufacturer says their parts are "100% OEM-compatible." That phrase, by itself, is meaningless. Here's how to disambiguate:

What to confirm before issuing a PO

For a 12-line BOM crossing main motors, gearboxes, hydraulic pumps, and control electronics, the procurement checklist before issuing the PO usually includes:

• Lead time per line item — gearboxes and slew bearings are the long-lead items (8–12 weeks is normal); pumps and motors are 4–6 weeks; control boards 2–3 weeks. The PO should set a single Required Date and let the supplier propose the staged dispatch schedule.
• Inco term — for marine refit work, FOB China port is most common because the buyer typically has freight forwarder agreements already in place. CIF is acceptable but adds 8–12% to the line cost.
• Inspection clause — third-party inspection (SGS, BV, Lloyd's) at the factory before despatch is standard for orders above USD 50,000. The cost is borne by the supplier; the inspection report is required for L/C release.
• Warranty period — 12 months from commissioning is standard. Some Chinese suppliers offer 18 months on remanufactured units; in that case, ask what failure mode is covered. "Manufacturing defects only" is a narrower warranty than "premature wear under rated duty cycle."
• Class certification — MacGregor cranes installed on classed vessels (DNV, BV, Lloyd's, ABS, KR, NK) may require that replacement parts also carry class approval. Confirm with the vessel's class society before specifying class-approved parts; otherwise the supplier's cost goes up by 15–25% unnecessarily.

Marine sourcing logistics: Norway → China → Norway

For a Norwegian buyer ordering from China, the typical logistics flow is:

1. Factory inspection at Ningbo / Qingdao (depending on the supplier's location). Lead time: 5–10 days from the supplier announcing readiness.
2. Sea freight from a Chinese port (most pump suppliers use Ningbo or Shanghai) to Rotterdam, Hamburg, or Gdansk, then inland trucking to the Norwegian yard. Sea transit is 28–35 days.
3. Norwegian customs clearance for refit parts is generally straightforward when the parts are itemised on the commercial invoice with HS codes 8412 (motor / pump) and 8413 (pump components). VAT and duty depend on whether the vessel is registered for ocean-going service.
4. Yard delivery coordinated with the dry-dock window. Most Norwegian crane refit work happens at a fixed dock window, so the supplier's commitment to a despatch date matters more than transit time itself.

Frequently asked questions

Closing thought

The Norwegian buyer who sent us this BOM was not asking for a catalogue. They were asking, implicitly, which Chinese supplier on your network actually understands marine hydraulic refurbishment, has the test equipment, and won't ghost when the pump fails on first installation?

That's the question this article exists to answer — by walking through the BOM, the failure modes, and the verification steps that separate a real remanufacturer from a trader. If you're working on a similar refit and want to skip directly to a shortlist, the supplier card above is where to start.
