Pro-Tec Geosystems Pte Ltd provides professional On-Board Vessel Indoor Air Quality Survey Services in Singapore for ship owners, ship managers, shipyards, vessel builders, offshore operators and marine contractors. Our service helps assess indoor environmental conditions inside vessel accommodation areas, workspaces and occupied spaces to support crew comfort, health, safety and marine habitability requirements.
An on-board vessel indoor air quality survey assesses indoor environmental conditions inside selected enclosed vessel spaces. It helps evaluate air quality, ventilation performance, humidity control, air movement, thermal comfort and possible pollutant sources.
The survey may include temperature, relative humidity, air velocity, carbon dioxide, carbon monoxide, particulate matter, total volatile organic compounds and other relevant parameters depending on the project requirement.
Crew members spend long hours inside cabins, mess rooms, recreation rooms, offices, control rooms and medical rooms. Poor ventilation, high humidity, odour, dust, fumes, CO₂ build-up or poor air-conditioning performance can affect comfort, concentration, rest quality and well-being.
A professional vessel IAQ monitoring survey helps identify areas where ventilation, housekeeping, air-conditioning performance or source control improvements may be required.
Ship indoor air quality survey services are commonly required during:
Pro-Tec Geosystems conducts marine indoor air quality survey and indoor climate assessment services with reference to applicable marine, class and project requirements.

| Site Observations | Odour, occupancy, housekeeping and sources |
For ship thermal comfort assessment, the focus is usually temperature, humidity and air movement. For broader IAQ assessment, CO₂, CO, particulate matter and VOCs may be included.
Measurements are performed using suitable direct-reading instruments at representative occupied zones. Readings are recorded after instrument stabilisation. The survey team may document number of occupants, air-conditioning status, ventilation condition, odour, housekeeping, open doors or windows and nearby.
The on-board vessel indoor air quality survey report may include vessel particulars, survey objective, reference criteria, methodology, instrument details, calibration information, monitoring parameters, measurement results, photographs, observations, conclusion and recommendations
Recommendations may include improving fresh air supply, checking air-conditioning performance, balancing air distribution, cleaning filters and diffusers, improving exhaust ventilation, controlling pollutant sources, improving housekeeping, reducing moisture build-up and reviewing occupancy levels.
