Urgent Underwater Support When Time Matters
When a vessel or underwater asset faces an urgent problem, response time, access, safety and clear evidence are critical. Inhaca Sub can support emergency underwater visual checks, Mini-ROV surveys and diving operations subject to location, permits, weather, safety review and operational feasibility.
Propeller Entanglement Removal
Ropes, nets, lines, wires and debris assessed and removed where safe and permitted.
Grounding & Hull Visual Inspection
Underwater visual documentation after grounding, impact, contact or suspected hull damage.
Sea Chest / Intake Blockage Check
Visual inspection and support for suspected blockage affecting cooling, generators or intake flow.
Emergency Mini-ROV Survey
Rapid underwater video evidence where diver entry is restricted, delayed, unsafe or unnecessary.
Lost Anchor / Chain Search Support
Underwater search, marking and recovery assistance subject to lifting plan and site conditions.
Underwater Obstruction Search
Visual search for submerged hazards, debris, dropped objects or obstructions below or near the asset.
Pre-Departure Clearance
Last-minute hull, propeller, rudder, sea chest or intake visual checks before sailing where feasible.
Urgent Intake / Water Asset Check
Mini-ROV visual support for selected water intakes, screens, tanks or industrial water assets.
Propeller Entanglement
Inspection and removal support for nets, ropes, lines, wires or floating debris.
Blocked Sea Chest / Intake
Visual checks and support for suspected intake blockage affecting vessel systems.
Grounding Damage Check
Underwater imaging of visible dents, coating loss, deformation or suspected contact areas.
Rudder Damage / Steering Issue
Visual review of rudder, stock area, hinges, pintles, nozzles and steering-related damage signs.
Shaft Line / Vibration Indications
Visual inspection for rope marks, blade damage, fouling, deformation or foreign object contact.
Dropped Object Search
ROV or diver-assisted underwater search for dropped tools, equipment or operational objects.
Lost Anchor / Chain
Search, visual marking and support to recovery planning for lost anchor or chain situations.
Collision / Berthing Impact
Inspection of visible deformation, coating loss, scuffing, impact zones and underwater contact areas.
Structural Dents & Plate Damage
Close visual evidence of affected plating, weld areas and visible hull irregularities.
UWILD Preparation Support
Underwater evidence gathering and pre-check support for class or owner review, subject to scope.
Pre-Departure Checks
Hull, propeller, rudder and intakes visually checked before departure where time and permits allow.
Submerged Obstruction Search
Visual detection of hazards below the hull, around berth, anchorage or work area.
Propeller Damage After Impact
Inspection of blades for visible chips, cracks, bent edges, abrasion and foreign object marks.
Underwater Fouling Check
Quick visual fouling assessment to support cleaning, performance and operational decisions.
Thruster & CPP Inspection
Nozzle, blades, tunnel area and CPP external condition visually checked where accessible.
Mooring Line / Chain Issues
Visual checks for wear, entanglement, seabed interaction or abnormal line/chain condition.
Leakage / Through-Hull Concern
Visual inspection around valves, fittings, hull penetrations and suspected underwater leak points.
Sea Chest Grid Damage
Visual checks for bent, blocked or damaged sea chest grids and visible obstruction.
Berth / Quay / Fender Check
Visual inspection of piles, quay walls, fenders, concrete surfaces and impact areas.
Urgent Water Intake / Screen Check
Mini-ROV visual support for selected dam, tank, pump station or industrial intake screens.
Best Information to Send
- Vessel / asset name and exact location
- Problem description and urgency
- Photos, drawings or previous reports if available
- Berth, anchorage or site access details
- Required permits, agent or site contact
- Preferred inspection or sailing deadline
Important Operational Notes
- Mobilisation depends on location, safety and permits
- ROV may be used before divers where practical
- Engines, propellers and thrusters must be secured for vessel work
- Some sites require client / port / terminal approval before deployment
- Final feasibility is confirmed after scope and HSE review
