Bridge & Block Marine
Certified Marine Spares & Navigation Electronics - Sourced Fast, Verified Always
Two disciplines. Deep, not broad.
We work in two areas and nothing else: marine diesel engine spares — cylinder components, fuel injection, valves, turbocharger consumables and separator parts — and SOLAS Type-Approved bridge electronics. Narrow coverage is deliberate. It means when you send us a part number, you are partnering with specialists who know your equipment inside out.
How we vet every part we source.
Step 1 — Confirm certification. Every navigation electronics product we source carries valid SOLAS-linked Type Approval. Every engine spare we source carries classification-society Approval of Manufacturers or material certification. No exceptions.
Step 2 — Confirm the fit. We work from your maker's nameplate and the part or section number in the instruction manual, not from a product category. Where a part is superseded, we identify the current equivalent and tell you what changed between them before you order.
Step 3 — Deliver. Once certification and fit both check out, we get you what you need.
Less noise, better results from the start.
Purpose-built marine procurement for zero-downtime operations.
A vessel alongside with a failed liner is not price-shopping — it needs the right part, certified, with a delivery date it can trust. We work across the certified aftermarket for the major engine families, including MAN B&W MC/MC-C and ME, Wärtsilä 32 and 46, Sulzer RTA and RT-flex, and Caterpillar 3512/3516 and MaK M32/M43.
We handle the cross-referencing, the certification checks, and the documentation. You get one contact, one quote, and a delivery commitment to a named port.
What we cover.
Navigation Electronics
Radar, AIS, ECDIS and GMDSS equipment carrying valid SOLAS-linked Type Approval, verified before quotation.

Cylinder liners, piston rings, crowns and covers; injectors, nozzles, HP pipes, pumps, plungers and barrels; exhaust and inlet valves, seats, spindles and cages; turbocharger bearings, nozzle rings and cartridges; separator bowl discs and seal kits. Including superseded and discontinued items for older tonnage.
What we need to quote
Send these five things and you'll have a quote inside 12 hours:
