Shipping Profitability: Save Money with Preventative Maintenance

Preventive maintenance is common practice in the shipping industry. It not only plays a significant role in enhancing a ship’s overall efficiency but also helps companies enjoy high returns. The primary benefit of preventive ship maintenance is its ability to detect potential problems ahead of time.

In addition to corrective and predictive maintenance, prevention is the next best course of action to ensure your ship’s operational efficiency and crew’s safety. While you might think that a routine underwater inspection is all you need to prevent issues in a marine vehicle, it’s more than that. Preventive maintenance also includes correct equipment purchasing, workers’ training, scheduled maintenance, and timely repairs.

Corrosion and Cathodic Protection of Your Vessel

What is Corrosion?

Corrosion is a naturally occurring process of materials returning to their natural state. As with any man-made material, a considerable amount of energy is put into the finished product through mining, smelting, and processing. It’s the act of corrosion that reverts these finished products to their original form.

The Importance of Proper Rudder Maintenance Practices

A rudder is one of the most important components in any marine vessel. It enables the helmsman to steer, control, and direct the ship in the sea.

A damaged rudder poses a high risk to the structural integrity of the ship. Without an efficient rudder, a ship can’t operate properly, even with all other systems intact. The rudder’s function and significance are quite similar to a propeller in that it converts rotational kinetic energy into power.

Sitting at the stern of the vessel and taking abuse from the prevailing vessel movements ahead, it is prone to a slew of anomalies making regular maintenance a must. Because of its location in the rear of the ship and its immersion in water, it is difficult to access from the surface for any type of repair work.

A comprehensive rudder maintenance and repair plan is essential to keep your marine vessel up and running.

Hull Cleaning Mistakes That Can Ruin Your Ship

Neglecting hull cleaning and professional ship care can end up costing you heaps of dollars in the long run. From potentially ruining the ecosystem (by harboring hazardous pests and marine species), a dirty hull can lead to various ship inefficiencies. If you’re new to the shipping industry or generally unaware of correct hull cleaning practices, our hull cleaning experts at Thai Subsea Services are here to help.

Marine Propellers: The Driving Force of Your Ship

A propeller, known as a ‘screw’ for its appearance is a fan-like piece of machinery attached to the stern of a ship. They come in many varieties and designs, they can be left-hand turning or right-hand turning, they are fitted in pairs or in threes and may be covered in shrouds and nozzles. However, their main function is the same – to propeller the ship!

Typically made from nickel-aluminum-bronze alloys, a propeller, or ‘prop’ is generally located at the stern of the vessel and attached to a rotating hub at the end of a shaft that is driven by the engine of a ship. These metals and their alloys are ten to fifteen percent lighter than steel and are impervious to corrosion. However, some propellers, particularly ice-class vessels, can be composed of much harder, stainless steel alloys.



Underwater Maintenance: What Your Vessel Needs

Regular maintenance of your vessel is important. It increases its lifespan, saves money, improves ship efficiency, and keeps your crew safe.

Regular inspections and maintenance are necessary procedures and encompass many things. Here’s a shortlist of things that your ship needs when undergoing underwater maintenance.

How to Choose a Subsea Service Provider

A good subsea service provider should be able to provide a wide range of services, such as underwater welding, hull inspection and cleaning, propeller polishing, biofouling assessments, transducer change-outs, underwater ship repairs like leak management, rope guard installations, and much more.

Here’s what you should look for when choosing your next subsea services provider:

State-of-the-art Equipment

It’s necessary for a subsea provider to have the appropriate equipment to carry out their services. Go for a subsea service provider with the most state-of-the-art machinery and equipment since there’s a greater chance for better work to be conducted and a lesser chance of damage to your assets.

Important equipment includes commercial diving gear recognized to the highest standards along with items like CCTV and HD camera systems, and name-brand underwater cleaning and welding equipment.

Reliable and Trustworthy

Ideally, your subsea service provider should comply with all the international standards and hold as many certifications and accreditations as possible. This will help prove that they’re reliable and trustworthy and competent, putting you at ease. You should check for testimonials and reviews and get in touch with their team so that you know exactly how qualified they are to deal with your vessel.

Qualified Team of Divers

A good subsea service provider must have a qualified team of professional and certified commercial divers. Competent commercial divers are necessary to perform routine class inspections as well as more technical maintenance and repairs of your ship. They should have the ability to identify problems like leaks, cracks, and damage and provide you with on-site solutions.

A commercial diver

Moreover, a qualified team of divers can also perform many other required tasks. Hull cleaning, for example, requires specialized techniques and equipment to ensure that no damage is done to the hull of your ship while cleaning. Commercial divers also perform potentially dangerous and but necessary tasks, such as underwater welding. These tasks require a level of skill and precision, and can only be performed by a team of highly experienced professional divers. If performed incorrectly, it may become costly for you— which is why it’s important to choose the right subsea services provider from the start!

Underwater Welding Basics

Underwater welding is a lucrative yet dangerous field and one of the best paid undertakings for commercial divers.

Since ships are subject to extraneous conditions like storms and ice or may become damaged by collisions and accidents, they sometimes require intervention by underwater welders.

Here’s a short intro for everything that you need to know about underwater welding.

3 Most Common Type of Ships

Though it may not seem like it, most of the ships that sail into the oceans are purposed for international freight transport.

However, there are many different kinds of ships. They vary in size, shape, functions, and even durability. Here are some of the most popular types of ships across the world!

Biofouling: Complying with the Guidelines

Biofouling is the accumulation of micro and macro-organisms composed of animals and plants on ship surfaces such as the hull plating, propeller, water inlets, and outlets, which cause long-term damage and degradation to your vessel. Additionally, it is recognized as a serious threat to marine life and the conversation of biodiversity in the oceans.
