1.Offshore platform supply vessels

In order to assist offshore oil and gas drilling activities, specialised ships known as offshore platform supply vessels (OSVs) are required. These ships are outfitted with a range of unusual technologies and tools that allow them to complete their duty safely and effectively.

The Bourbon Liberty 300 series of ships is one illustration of an OSV with distinctive systems and apparatus. The Dynamic Positioning (DP) system that these ships are outfitted with allows them to retain their position and heading without the usage of anchors. This is crucial in offshore drilling operations because it requires the ship to remain still as it loads and unloads supplies and equipment onto the drilling platform.

The enormous cargo deck on the Bourbon Liberty 300 series lets the ship to handle a variety of supplies and machinery, including as drilling fluids, cement, and drill pipes. The ships also have a FiFi (Fire Fighting) system that enables them to act swiftly in the event that a fire breaks out on the drilling platform.


Specialised ships called “icebreakers” are made to travel through ice-covered waters. These ships can function in some of the harshest environments on the planet thanks to a range of special systems and apparatus.

Examples of ships with distinctive keel designs

A ship’s keel, which extends from the bow to the stern along the centerline, serves as its spine. It gives the ship stability and acts as a mounting place for the propulsion system. While most ships have very straightforward keels, others have special keel shapes that enhance performance or fulfil a particular function. We will look at three instances of ships with unusual keel shapes in this post.


A multihull sailboat with a special keel configuration is called a trimaran. Trimarans have three distinct hulls, with the central hull serving as the main keel, as opposed to a single keel running along the centerline. Compared to conventional monohull sailboats, this design offers increased stability and speed among other benefits.

A trimaran often has a central keel that is deeper than the keel on a monohull sailboat, which contributes to the trimaran’s increased stability in choppy waters. The two smaller hulls that are located on either side of the main hull also serve as outriggers, which help keep the boat from toppling over in strong gusts. Due to the three hulls’ reduced water resistance, this design also makes trimarans faster than monohull sailboats.

2.Icebreaking Tanker

Ships called “icebreaking tankers” are made to travel across ice-covered seas while transporting oil or other liquids. The reinforced keel of these ships is typically made to break through ice, allowing the ship to travel through the frozen waterways.

The ship also has two bow thrusters, which can be utilised to push the vessel through ice if it becomes stuck.

3.Wave-Piercing Catamaran

High-speed boats that can cut through waves are called wave-piercing catamarans. The distinctive keel form of these ships enables them to cut through the waves as opposed to riding over them like conventional monohull vessels.

A wave-piercing catamaran’s keel is often short and pointed, allowing the vessel to cut through the waves. The keel is frequently inclined upward and towards the bow as well, which aids in raising the boat out of the water and lowering drag. Compared to conventional monohull vessels, wave-piercing catamarans may travel at higher speeds and with greater comfort because to their design. The Condor Vitesse, which operates a high-speed ferry service between the UK and France, is an illustration of a wave-piercing catamaran with a distinctive keel design.


In conclusion, ships are intricate machines made up of many elements that work together to accomplish a certain task. Every component of a ship, from the bow to the stern, is essential to the ship’s ability to travel the sea safely and effectively. Each component’s design is based on the ship’s intended usage, which can range from carrying out scientific research and military operations to transporting cargo and passengers.

Ships have incorporated a variety of avant-garde designs and technology throughout history to increase their effectiveness and performance. The distinctive bow designs of icebreakers and container ships, the hull designs of cruise ships and hydrofoils, the propulsion systems of nuclear-powered submarines and LNG carriers, and the numerous systems and equipment used in scientific research vessels and offshore oil platforms are a few examples.

While improvements in ship technology have substantially increased the safety and effectiveness of ships, they have also brought forth new difficulties and worries, notably with regard to the impact on the environment. There are constant initiatives to create more environmentally friendly and sustainable business practises and technologies because the shipping sector contributes significantly to global greenhouse gas emissions.

The safety of ships is another constant worry, especially in light of mishaps and catastrophes like collisions, groundings, and sinkings. There is always potential for improvement in terms of safety in the business despite the introduction of safety rules and standards like the International Convention for the Safety of Life at Sea (SOLAS).

In general, new developments and improvements are created every year in the realm of ships and marine technology. Ships must be carefully designed and built, striking a balance between form and function while taking into account aspects like speed, stability, manoeuvrability, and safety. The shipping industry must continue to adapt and develop in order to face new challenges and guarantee a sustainable and secure future for all as demand for international shipping keeps rising.
