Anemometers Service Companies

An anemometer is a small instrument that measures wind speed and, on most designs, wind direction. On board a vessel or offshore unit, it sits on the mast or monkey island and feeds data to the bridge, the DP console, the crane safe-load indicator, and the helideck status panel.

When the reading drifts, the systems connected to it start making bad calls. Cranes keep lifting past the wind limit. DP vessels misread the weather window. Helidecks stay open when they should close. 

Keeping these sensors accurate takes proper reference equipment and class-approved paperwork. This work is best handled by specialist anemometer service companies. RecordsMarine keeps a verified directory of these firms, grouped by port and region, so you can book one during your vessel's next call.

Where Anemometers Are Used in the Marine Industry

Wind measurement is built into almost every vessel and offshore asset where safety depends on the weather:

Merchant ships — tankers, bulkers, container vessels, gas carriers, and reefers

• Offshore units — OSVs, jack-ups, drillships, FPSOs and semi-submersibles
• Cruise, passenger, and RoRo vessels
• Naval and coast-guard fleets
• DP-class crane barges, heavy-lift vessels, and cable-layers
• Shipyards during newbuilding and sea trials
• Ports and terminals — STS and RTG cranes, bulk berths, harbour-master towers
• Offshore wind installation vessels, SOVs, and CTVs

How to Choose an Anemometer Service Company

When our team vets a supplier for this directory, we look at five things:

• In-house calibration standards traceable to a national metrology institute
• ISO/IEC 17025 accreditation covering ultrasonic, cup, and vane sensors
• Class-society approvals from ABS, DNV, Lloyd's Register, Bureau Veritas, or ClassNK
• A brand-neutral workshop not tied to a single manufacturer
• A contractual response time, ideally 24 to 48 hours in main ports

A firm that cannot tick all five boxes is really a calibration lab or a reseller rather than a full marine service provider. 

Industry Standards and Regulations

Reliable anemometer service providers in the marine sector work to recognised standards, so their paperwork holds up during a class or flag-state inspection. The key benchmarks are:

• ISO/IEC 17025 for the calibration work itself
• Class-society rules from ABS, DNV, Lloyd's Register, Bureau Veritas, and ClassNK for shipboard installations
• SOLAS and IMO guidance covering bridge navigation equipment
• IEC 60945 for marine navigation and radio equipment fitted to the bridge
• CAP 437 for helidecks on ships and offshore installations

Before hiring a provider, ask for a sample calibration certificate and check that it names the standard that applies to your vessel or unit.

FAQs 

What do anemometer service companies actually do?

They calibrate, repair, install, and recertify wind sensors on ships and offshore units. A good provider handles every marine brand and issues calibration certificates that class surveyors, insurers, and port-state control officers recognise.

How often should the sensor be recalibrated?

Once every 12 months is standard for most vessels. But for DP-class ships, crane barges, and helideck-equipped units usually move for six months, because drifting on those assets carries real operational cost.

Can one company service every anemometer brand on a mixed fleet?

Yes, provided the firm is truly OEM-independent. Our directory only lists companies that service Gill, Thies, Vaisala, LCJ Capteurs, Observator, Deif, Furuno, and other marine brands under one agreement.

How quickly can a provider attend a vessel in port?

In major shipping hubs, 24 to 48 hours is a realistic target. Anything slower usually means the provider is subcontracting the job rather than sending its own engineers on board.

Do I need a service company for a newbuilding too?

Yes. The best providers also handle sea-trial commissioning, mast surveys, and cable work during newbuilding. Using the same firm for installation and annual servicing avoids the hand-off problems that come with mixing suppliers.
