Seakeeping analysis is measuring how a watercraft or any other water vessel can withstand conditions while on the waters. A ship, or a boat in that case, that has perfect sea keeping ability is referred to as seaworthy, and it will be able to operate efficiently and effectively even when in very high seas. What is normally used during such analysis include a number of things among them the steel catenary risers.

Sea keeping ability is measured using the following factors.


This is one of the first things used in seakeeping analysis. Where is the ship intended to operate? Or what will be the role of the ship while on the high seas. Basically, mission is one of the key factors used when it comes to seakeeping analysis.

The Environment

Just like mission, the environment also plays a significant role as it is one of the measures. Normally, what is looked into are the conditions under which the ship or the boat is going to operate. The conditions can be described as wind speed, sea state, and geographic region. Additionally, all these conditions can be combined.

Ship Response

How is the ship going to respond to the external and environmental factors? Ideally, the responses are the function of the environment and the ship’s features and characteristics.

Seakeeping analysis impacts directly on the design of the vessel. Ship motions are very vital for determining dynamic loading of the crew, cargo, structural element and even the ship components. It is put under great consideration when determining key dimensions of the sea vessel. Additionally, it will play a key role when you are creating the general arrangements of the ship interior.

Factors That Affect Seakeeping

When it comes to seakeeping analysis, there are multiple factors that can impact directly on how the ship will respond correctly. Some of these factors are highlighted below.


Practically, the larger the ship, the lower motions it will have than a smaller ship. Why is this case? Ideally the relative size of the wave is lower.


Normally, when a ship is stable, it will tend to follow a wave more close than the one that is less stable. In short, a ship with more stability will have high acceleration, but with very low amplitude of motion.


Displacement plays a key role when it comes to seakeeping analysis. A ship that is heavy will have low motions when compared with a lighter ship.

Human Factor

This is often one of the most critical factors when it comes to seakeeping, especially when it comes to smaller vessels. You certainly have to stay injury free, get sufficient sleep and avoid sickness.


The larger the water vessel, the lower its chances of it immersing. Deck immersion is normally one of the seakeeping analysis criterion. It actually affects the mission abilities of quite a number of water vessels.
