Frequently asked questions
How often must a 15 ppm bilge alarm be calibrated?
At least at every IOPP renewal survey under MEPC.107(49); many owners calibrate annually to avoid PSC deficiencies.
Can you calibrate onboard without removing the unit?
Yes. We calibrate onboard with certified test samples and issue the certificate on completion.
How quickly can you attend a vessel in Sharjah?
We work 24/7. For most Sharjah ports and anchorages we can mobilise the same or next day, depending on the scope, spares and port access permits. Call or WhatsApp +971 55 659 9860 for urgent jobs.
