Marine fouling increases hydrodynamic drag, cutting speed and driving up fuel consumption and emissions. Our teams clean the entire wetted surface — flat bottom, vertical sides, boot-top and niche areas — returning the hull to a smooth, efficient condition.
We match the method to the level of fouling and the vessel's antifouling coating, so growth is removed effectively without damaging the paint system.
Recommended cleaning frequency ranges from every few months to annually, depending on trading route, idle time and coating condition.
The propeller is one of the most performance-sensitive surfaces on the vessel. Even light roughening or fouling of the blades measurably increases fuel consumption. Our divers polish each blade progressively to a mirror-grade finish.
Propeller polishing is often carried out together with hull cleaning during the same underwater attendance, maximising the fuel-efficiency gain from a single port call.
Underwater Inspection In Lieu of Drydocking (UWILD) lets vessels satisfy survey requirements without the cost and downtime of a drydock. Our divers carry out class-oriented inspection of the hull, rudder, propeller, sea-chests, anodes and other underwater fittings.
Live video is streamed to the surface so superintendents and surveyors can observe and direct the inspection in real time. Every survey is closed out with structured imagery and a written report.
Divers communicate live during operations while surface teams watch the video feed — so masters, superintendents and surveyors see exactly what the diver sees, as it happens.
Detailed ETA planning accounts for tidal currents and port schedules, in close coordination with agents and vessel masters to reduce delays and off-hire time.
From compliant cleaning to inspection, blanking and salvage — one accountable diving partner.
Captured, compliant hull cleaning to New Zealand MPI's Craft Risk Management Standard for biofouling — for vessels bound for New Zealand ports.
Underwater Inspection In Lieu of Drydocking — class-oriented survey of hull, rudder, propeller and appendages with live video and full reporting.
Fitting and removal of sea-chest blanks to isolate intakes for valve, pump and pipework maintenance, plus grating clearance and refit.
Underwater salvage support — recovery of lost items and equipment, debris and obstruction clearance, and assistance to casualty operations.
Underwater inspection of quays, jetties, piles, fenders and berth structures — condition assessment with photo and video documentation.
Remotely operated vehicle cleaning and inspection for large flat areas, deep drafts and strong-current conditions — with recorded visual survey.
From enquiry to close-out report, every attendance follows a disciplined sequence built to protect your schedule.
Share the vessel particulars, port and window. We assess fouling expectations, tides and access, and confirm scope and quote.
We align with the agent, master and superintendent on ETA and berth, and mobilise the dive team and equipment to meet the vessel.
Divers or ROV carry out cleaning, polishing or survey with live video to the surface — safe, methodical and fully observed.
Results are checked zone-by-zone against the scope, with before/after imagery captured throughout.
You receive a structured report with media and recommendations — ready for your records, class and charterers.
