FREQUENTLY ASKED QUESTIONS

What piping services does SEATEC PIPE provide?

We cover the full chain of ship piping work: on-board pre-inspection and 3D laser scanning, engineering and class submission drawings, pipe spool fabrication, surface treatment, logistics and on-board installation — one team from first survey to final acceptance.

How accurate is your 3D scanning?

We use the FARO Focus S350 laser scanner for general arrangements (accuracy 0–2 mm) and the SIMSCAN 22 handheld scanner for confined spaces (accuracy 0.1 mm). The scan is verified against the 3D model with a deviation colour-map analysis before any drawing is issued.

How long do the on-board survey and engineering take?

The on-board 3D scanning usually takes one day. Engineering takes about 7 days when based on handheld scanning and up to 14 days for large FARO-scanned areas, including modelling and production drawings.

How long does a BWTS piping installation take on board?

A typical BWTS piping installation is completed within 10–12 days by our riding team. For two BWTS sets on the same vessel the duration is about 15–18 days, subject to the final scope and the vessel's schedule.

Which standards do your piping products follow?

Our pipe fabrication follows the STS pipe standard QSTS-097-2020 and applicable CSQS requirements; hot-dip galvanizing follows GB/T 13912-2002; and workmanship aligns with IACS Recommendation No.47 where applicable.

Do you hold class approvals such as DNV?

Our projects are routinely delivered with class attendance and class-accepted documentation. DNV material certificates, inspection reports and pressure test reports are issued per project, and class certificates are available on request. Please contact us for documentation relevant to your project.

Which vessel types have you served?

Since 2018 we have completed piping work on more than 300 vessels, including bulk carriers, tankers, container ships, general cargo vessels and offshore units — mainly BWTS retrofits, scrubber retrofits and repair piping.

Can installation be carried out during the voyage or at anchorage?

Yes. Our riding teams can attend at the shipyard, at anchorage or during the voyage, depending on the vessel's schedule. This keeps off-hire time to a minimum.

What piping materials can you fabricate?

We fabricate carbon steel, stainless steel, CuNiFe (copper-nickel), GRE/GRP and plastic piping, with matching flanges, fittings and surface protection for each system.

What surface treatment options are available?

Hot-dip galvanizing to GB/T 13912-2002, acid cleaning and passivation, shop primer and full coating systems, and plastic or rubber lining for corrosive media. Coating reports are issued for every batch.

How quickly will I receive a reply to my inquiry?

We reply to every inquiry within 24 hours. For quotations it helps to attach drawings or photos of the existing piping, the required pipe specifications and the vessel's schedule.

Where are you based and which ports do you cover?

We are based in Shanghai, China, and our teams attend vessels at ports and shipyards worldwide. Logistics for pipe spools is arranged by road, sea or air to match the vessel's schedule.
