Technical superintendents, naval architects, and commercial fleet managers manage rigorous drydock and structural integrity commitments: tracking ultrasonic plate thickness measurements (UTM), managing ballast tank coating conditions, coordinating intermediate underwater UWILD inspections, and ensuring continuous Class Society hull survey compliance. When hull corrosion reports, sacrificial anode depletion logs, and drydock repair specifications remain trapped across scattered shipboard spreadsheets and paper binders, technical directors lose visibility and merchant vessels face costly drydock budget overruns, structural condition notes, or Port State Control detentions. Fleet Rabbit delivers dedicated cargo ship hull inspection and drydock-scheduling software, unifying digital structural condition mapping, automated Class survey milestone tracking, and drydock repair itemization into one centralized maritime hub. Eliminate drydock off-hire delays, maintain audit-ready structural survey records, and enable chief officers and superintendents to capture complete hull and tank inspection records offline at sea with zero satellite connectivity.

Why Generic Asset Tools Fail Cargo Ship Hull & Drydock Management
Standard enterprise maintenance software is built for static industrial plants or highway assets, completely lacking the marine structural hierarchy, Class Enhanced Survey Programme (ESP) requirements, and drydock specification workflows essential to merchant vessels.
01
Deep-Sea Ballast Tank Inspection Blackouts
Cargo vessels conduct ballast water tank and void space visual checks in transit with zero satellite connectivity; cloud-only systems freeze, forcing officers to record corrosion notes and coating scores on paper.
02
Fragmented Ultrasonic Gauging & Corrosion Logs
Ultrasonic thickness measurements (UTM) and plate renewal records stored across disconnected PDFs make it difficult for superintendents to identify accelerated wastage in cargo hold frames before Class survey deadlines.
03
Unstructured Drydock Repair Specifications
Compiling drydock work packages from email threads and scattered defect notes leads to missing underwater valve renewals, inaccurate steel weight estimates, and costly shipyard change orders.
04
Lapsed Intermediate & UWILD Survey Windows
Tracking 30-month intermediate in-water surveys (UWILD) and 5-year special drydock surveys across multi-vessel fleets on static spreadsheets exposes operators to Class condition notes and suspended trading certificates.
