C-Leanship: ROV Hull Cleaning that Quickly Cuts Fuel and Downtime

Biofouling is a quiet tax on every voyage, and C-Leanship’s pitch is to remove it without blowing the schedule. They deploy ROVs to inspect and clean hulls and propellers during port calls or at anchorage, so you recover speed at the same throttle, trim fuel use, and keep the call on track. The value is practical: fewer diver dependencies, predictable windows, and documentation that supports biofouling expectations. If you are watching OPEX and compliance risk between drydock cycles, this is a lever you can pull.

Shipowners save by:
  • Recovering fuel efficiency: ROV hull and propeller cleaning restores smooth surfaces, so the same speed requires less fuel compared with fouled condition.
  • Real Discounts: C-Leanship offers a fixed discount of 2% to customers who come via the Ship Universe Savings Alliance (Susa), which can result in notable savings on the final invoice.
  • Spares in transit handled end-to-end: Customs and logistics for ship spares in transit reduce delays, storage charges, and misrouted packages.
  • Cutting schedule impact: Cleaning can be done during port calls or at anchorage, including alongside bunkering in some cases, which reduces off-hire versus yard-based options.
  • Keeping compliance on track: A documented biofouling management approach supports inspections and port expectations and reduces the chance of biofouling-related delays.
  • Improving safety and predictability: Remote ROV methods avoid many diver operations and deliver repeatable results where local permissions allow.
  • Timing maintenance smarter: Underwater inspections show when performance loss justifies a clean, helping avoid premature or late interventions.
  • Leveraging regional coverage: Active service hubs in Singapore and Busan support Asia routes and regional calls with short response times.

C-Leanship presents a focused, practical offer: recover performance and clean biofouling with ROVs during normal calls, keeping schedules intact while trimming fuel use. The value sits in predictable windows, fewer diver dependencies, and documentation that supports biofouling expectations at port. If you’re trying to hold speed between drydock cycles without routing to a yard, this is a credible option to keep in the mix, especially on trades where a short alongside or anchorage window can double as a clean.
