Professional Underwater Hull Cleaning

In-water hull cleaning services designed to reduce fuel consumption, improve hydrodynamic performance and protect coating life.

HULL CLEANING

HIGH-QUALITY UNDERWATER HULL CLEANING SERVICES

At U-SEADIVING, we deliver high-standard underwater hull cleaning services in all major Turkish ports — including İzmir, Aliağa, İstanbul, Yalova, Gemlik, Kuşadası, İskenderun, and Nemrut Bay — ensuring vessels maintain maximum performance and efficiency without the need for dry-docking.

Our certified commercial divers, approved by leading classification societies such as DNV, BV, RINA, LR, ABS, NK, and KR, perform every in-water hull cleaning operation using modern hydraulic Brush Kart systems designed to protect the coating while ensuring a deep and effective cleaning result.

WHY UNDERWATER HULL CLEANING MATTERS

A fouled hull dramatically affects a vessel’s performance and operating cost. Marine growth such as algae, barnacles, and shell deposits increases frictional resistance, leading to:

Higher fuel consumption and CO₂ emissions
Reduced speed and maneuverability
Increased vibration and engine strain

Shortened coating life and more frequent dry-dock intervals

With our underwater hull cleaning services, vessel owners benefit from cleaner surfaces, reduced fuel costs, and improved operational efficiency — all while keeping environmental compliance and performance at the forefront.

Scope of Underwater Hull Cleaning Services

U-SEADIVING provides comprehensive underwater hull cleaning services covering all major submerged hull areas that affect vessel performance and fuel efficiency. Our certified commercial divers use controlled hydraulic brush systems suitable for different fouling levels and coating conditions.

Our underwater hull cleaning scope includes:

Flat bottom hull cleaning to remove marine growth and biofouling
Vertical hull side cleaning from waterline to keel
Cleaning of curved hull sections, including bilge areas and transitions

Bulbous bow cleaning to restore smooth water flow
Cleaning around bilge keels and structural edges
Surface cleaning near rudder and stern areas connected to hull performance

All cleaning operations are carried out with coating protection in mind, using appropriate brush types and controlled pressure to avoid damage to antifouling systems.

Our Hull Cleaning Equipment & Method

U-SEADIVING performs underwater hull cleaning using advanced hydraulic brush systems designed to deliver effective results while protecting antifouling coatings. Our equipment allows precise control of contact pressure, ensuring safe cleaning across different paint types and hull conditions.

Depending on the fouling level and surface condition, our divers select suitable brush materials such as nylon, stainless steel or wire brushes. This controlled approach enables efficient removal of algae, slime, barnacles and other marine growth without causing unnecessary coating damage.

Before each operation, our teams conduct an underwater inspection to assess fouling intensity and coating condition. After cleaning, a follow-up inspection is performed to verify results and document the final hull condition.

All hull cleaning work is supported by diver-to-surface communication and full photo/video documentation for technical records.

IMO & Environmental Compliance in Hull Cleaning

U-SEADIVING conducts underwater hull cleaning operations in line with international environmental practices and modern maritime efficiency standards. Proper management of hull biofouling is a key factor in reducing fuel consumption, lowering emissions and supporting vessel environmental performance.

Our cleaning methods are aligned with IMO biofouling management principles and in-water cleaning guidance. By using controlled brush systems, appropriate cleaning tools and environmentally responsible procedures, we help minimize the release of harmful substances while maintaining coating integrity.

Regular underwater hull cleaning contributes to reduced hydrodynamic resistance, improved fuel efficiency and lower carbon emissions. These improvements support shipowners in meeting environmental performance goals and maintaining efficient vessel operations.

All operations are documented with photo and video records, which can support technical reviews, environmental documentation and performance monitoring.
