Rudder Repairs

Rudder Repairs

Maintain the integrity and performance of your ship’s rudder with our Wencon solutions. Rudder blades are prone to cavitation and corrosion, especially in aggressive marine environments. The construction involves welded plates that can suffer from wear and rust, particularly at the weld seams. Our repairs include filling these seams with high-quality materials, reinforcing the structure effectively.

We also address issues such as loose bearings and bimetallic corrosion, which can cause significant damage over time. Our services include casting new thrust and bearing bushings, ensuring a precise fit and restoring the rudder’s functionality.

Stern Tube

Stern Tube

Ensure the reliability of your ship’s propulsion system with our guidance to repair and protect the stern tube. The stern tube, where the propeller shaft exits the hull, is highly susceptible to bimetallic corrosion, which is often left unpainted and can sneak into the main propeller or stern tube seal boxes. This corrosion can lead to leaks and misalignment in the seal boxes, posing serious operational risks.

Our repair solutions address these issues efficiently, often completing the necessary repairs within a day, minimizing both cost and downtime. Protect your vessel from costly damage and operational delays with our expert stern tube repair services.

Propeller Cavitation

Propeller Cavitation

Protect your propeller blades from the damaging effects of cavitation with our specialized repair services. Cavitation, caused by vacuum on the pressure and suction sides of the blades, can lead to significant erosion, much like sandblasting a single spot repeatedly. This damage is commonly seen on rudders and propeller blades.

Our repair solutions involve filling and reinforcing these damaged areas with new material, effectively preventing further cavitation damage. By detecting and addressing cavitation early, we can ensure that your vessel continues to operate smoothly and efficiently, using Wencon products to provide a lasting solution.

Exhaust Repair

Exhaust Repair

Keep your ship’s exhaust systems operating smoothly with our repair solutions for exhaust systems made for high temperature. Exhaust components, including bellows and compensators, are prone to damage from engine vibrations, high temperatures, and sulfur in exhaust gases.

These conditions can lead to cracks in expansion joints and weld failures. Our repair services tackle these challenges head-on, ensuring your exhaust systems withstand the challenges of fuel combustion.

Heat Exchange Covers and Coolers

Heat Exchange Covers and Coolers

Enhance the efficiency and longevity of your ship’s heat exchange systems with our specialized repair services. Heat exchange covers, also known as end covers, and plate heat exchangers can suffer from rust and expansion, leading to internal pressure and leaks. Our expert repairs ensure these end plates are fully rebuilt and perfectly flat, preventing future issues.

We also offer comprehensive services for pipe coolers, including the restoration of pipes, end covers, and return covers, significantly extending their lifespan. Trust Wencon solutions to keep your cooling systems in top condition.

Seawater Filter

Seawater Filter

Protect your ship’s seawater intake systems with our repair solutions for filters, strainers, and housings. These components are constantly exposed to both corrosion and bimetallic corrosion, affecting all types of water entering the vessel, including:

  • process water
  • drinking water
  • cooling water

Corrosion can lead to leaks, allowing water to enter the ship, which is something you of course want to avoid.

Our Wencon repair solutions ensure your seawater strainers and housings remain intact and efficient, preventing unwanted water ingress and maintaining the integrity of your vessel.

Scrubber Outlet

Scrubber Outlet

Ensure the integrity of your scrubber outlets and the surrounding hull with our repair services. Scrubber wash water flows through GRE pipes and stainless steel valves that resist corrosion, but as it exits through the overboard pipes, it can often cause significant damage to the surrounding hull. This common issue is frequently overlooked during routine maintenance.

Our repair solutions address the degradation caused by scrubber wash water, reinforcing overboard pipes and protecting the hull from corrosive damage.

Explore how our comprehensive repair services can prevent and resolve issues with your scrubber outlets, ensuring the longevity and safety of your vessel.

Hydraulic Ram

Hydraulic Rams

Optimize your vessel’s operations with our specialized repair services for hydraulic rams. Rebuilding the surface of hydraulic pistons, especially those with chrome and ceramic coatings, can prevent costly replacements. These pistons are expensive, and repairing them can result in significant savings for shipowners. Taking a ship out of charter for piston replacement is extremely costly. Our epoxy repair solutions allow you to refurbish cylinders within a few days, avoiding the hassle and expense of cutting out and installing new cylinders.

Discover how our efficient repair services can keep your hydraulic rams in top condition and save you time and money.

Thruster Gear Housing and Tunnels

Thruster Gear Housing and Tunnels

Thruster gear housings often suffer from bimetallic corrosion due to the presence of multiple metals in a confined space, placing high demands on zinc anodes. Instead of allowing corrosion to damage the unit, a stainless steel ring is welded inside the thruster. The cast iron thruster is more susceptible to corrosion compared to the ship’s hull and the stainless steel ring. Propellers on the thruster resist corrosion better, but the welded joint between the stainless steel ring and the thruster can still lead to significant bimetallic corrosion, causing the ring to loosen. This area can be protected effectively.

With numerous mechanical parts that need to fit together perfectly, replacing a thruster often involves a long wait time, leading to significant cost savings when opting for effective protection solutions by Wencon.

Refurbishment and general corrosion protection in the area of achor and mooring winch, for instance:

  • Refurbishment of holding break
  • Cast to fit bearings, liners and bushings

With Wencon products, we are able to build up the construction to original shape and apply a double layer coating which will protect the asset against future corrosion.

Tank Pittings

Tank Pittings

Protect your ship from the damaging effects of tank pittings caused by corrosion and wear in the suction well due to high flow rates.

Over time, paint can erode, leading to wear on the steel and other materials. Our solutions effectively stop pittings by sealing them, preventing holes that could compromise the integrity of your vessel. Avoid costly repairs and maintain your ship’s safety with our specialized sealing techniques.

Protection of Suction wells in cargo tank
Ballast Pipes

Ballast Pipes

Ballast water is essential for maintaining safe operating conditions throughout a voyage. It reduces stress on the hull, enhances transverse stability, improves propulsion and maneuverability, and compensates for weight changes due to varying cargo loads and fuel and water consumption. However, when ballast pipes start leaking, it can compromise these benefits and pose significant operational challenges.
