FPSO hulls berth at the yard for integration, for example Cidade de Marica in 2015.
Niteroi lies across Guanabara Bay from Rio de Janeiro and is mainly a commercial city. The two power-generation modules for the P-56 platform were built by Rolls-Royce with UTC Engenharia at UTC's site in Niteroi, an example of offshore topside fabrication done in the city. This page explains what to look for in a hazardous area mobile phone for Niteroi, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Niteroi: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Zone | 0, 1 or 2 for gas; 20, 21 or 22 for dust | Designed for Zone 1 and Zone 21 |
| Gas group | IIA, IIB or IIC | IIC (target) |
| Area drawing | The operator's own classification drawing | Decided by the site operator |
| Where it applies | Niteroi: FPSO module fabrication and integration, Shipyard tank and hull work, Fuel and gas handling at quaysides | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Niteroi. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Niteroi has a tropical monsoon climate with warm temperatures year-round and frequent rain.
Niteroi lies across Guanabara Bay from Rio de Janeiro; it was founded in 1573 and served as capital of Rio de Janeiro state until 1975, apart from a short period from 1894 to 1903.
Industry reports in 2025 said Hanwha Ocean was considering a shipyard in Niteroi to meet local-content requirements tied to Petrobras projects such as the FPSO P-86 tender.
A 2011 Getulio Vargas Foundation study classed Niteroi as Brazil's richest city by share of high-income households, and it is the second-largest formal employer in Rio de Janeiro state.
The Mauá shipyard grew from a Niterói foundry and shipyard bought in 1846 by Baron of Mauá, and its 2000 joint venture with Jurong Shipyard added construction of oil and gas platforms.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Niteroi. Niteroi is mainly a commercial city, so the classified areas here are essentially the shipyard: module fabrication and integration, tank and hull work, and fuel and gas handling at quaysides. The yard operator classifies them for each job; SAMS does not.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Likely candidates are fpso module fabrication and integration, shipyard tank and hull work, fuel and gas handling at quaysides. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Mainly shipyard and fabrication work: platform modules, power packages and vessel outfitting for the Campos and Santos basins. Hazardous areas arise on tanks, engine spaces and process modules, so zone definitions come from the yard's classification plan.
Niteroi faces Rio across Guanabara Bay and is connected by road bridge and ferry, so commuting between yards and Rio offices is common. Ask local logistics staff about peak traffic when scheduling deliveries of equipment.
The sheet notes that the latest sourced integrations are 2014-2015, so current workload is not confirmed. A buyer should ask the yard directly. Confirm approvals and documentation requirements with the site operator before planning a fleet.
