Introduction

Cruise ships have been a big part of the tourism industry for many years, providing people with the best vacation experience. While cruising, the ship‘s crew must ensure the safety of the passengers while also making sure they have a great time (Biolcheva, Valchev 2023). However, one of the most crucial parts of managing a cruise ship‘s journey is weather routing.

Weather routing is the process of choosing the best possible route for a ship, considering the weather conditions such as winds, waves, and currents. The importance of weather routing for cruise ships cannot be overstated. The safety of the passengers and crew greatly depends on the decisions the captain makes when choosing the ship‘s route.

The operating cruise lines also prioritize environmental preservation and protection, so responsible ship captains must use their best judgment in assessing ways to reduce fuel consumption and, consequently, carbon emissions, as well as in choosing the most time- and fuel-efficient routes to their destinations.

The trustworthy weather routing services step in at this point, acting as an advisory service and effectively addressing the necessary information for safety and efficiency by creating, upon request, an ideal track for ocean voyages based on forecasts of weather, sea conditions, and ship’s unique characteristics for a particular transit. Based on this equation, the term “optimum” is used to refer to the greatest passenger, crew, and vessel safety, as well as the least amount of fuel used, and time spent at sea.

Depending on the details of the potential voyage and the ship’s captain’s request, the operations department will suggest an effective weather routing organization in accordance with the cruise line’s weather routing policy (Chen et al. 2021). According to the instructions of the ship’s operator, the ship’s captain must create a detailed journey plan from the quay of the port of departure to the quay of the port of arrival (Bui et al. 2008; Gancheva 2021). The “Bridge Team Management” brochure from the Nautical Institute and the “Bridge Procedures Guide” document from the International Chamber of Shipping must be read while creating the trip plan (ICS, 2022, Nautical Institute, 2018).

All the weather conditions, both anticipated and actual over the duration of the voyage, must be mentioned and considered when creating the voyage plan. The weather routing services give all this data.

Cruise ships have different routes for different seasons, and the weather factors play a significant role in determining these routes. The captain must have the latest weather forecast information and use it to make decisions. Routing the ship through rough waters, high winds, or intense storms can lead to significant safety risks for the crew and passengers.

Furthermore, the importance of weather routing for cruise ships is evident in the level of comfort that passengers enjoy while cruising. Nobody wants to be on a ship that thrashes around in choppy waters. By routing the ship away from rough weather, passengers will enjoy a smoother ride, allowing them to relax and enjoy their vacation without feeling seasick.

Incorporating weather routing systems also allows cruise ships to save fuel, time and reduce emissions. The ship‘s crew can use technology to monitor the weather and route the ship, ensuring it uses the least amount of energy possible while still arriving at the destination within the planned timeframe.

The implementation of these systems in maritime education and training has become increasingly important, as it is necessary for captains and crew members to have an in-depth understanding of weather patterns and how to navigate through storms.

Weather-routing technique

A weather routing system involves the use of satellites and advanced computer programs to monitor weather conditions. These programs use real-time data to provide guidance on how to avoid storms, reduce fuel consumption, and improve safety. The technique is a strategic approach used to calculate the shortest and the most efficient route for a ship based on the prevailing weather conditions (oceanweatherservices.com). It accounts for the vessel’s speed, its defined route, and the developing weather patterns. The technique relies on weather forecasts received from various sources, including satellite images, buoys, and weather stations located along the ship’s planned route. This information is combined with ocean current data, vessel performance information, and other factors to recommend the most optimal route for a particular voyage.

To do effective weather routing the following steps must be considered:

– You must be able to construct ship performance curves and comprehend a wave chart.

– Create the shortest track you can.

– Obtain the track that takes the least amount of time;

– Verify the track’s viability in light of navigational and safety risks.

Three different sea conditions are used to draw the performance curves:

• waves on the following sea;

• waves on the beam sea;

• and waves on the head sea.

To plot these curves, information on ship speed in various wave conditions must be taken from the logbook of the ship or from a sister ship. The curves are interpolated using the available data if there is insufficient data. A wave diagram is displayed on Figure 1.

The blue curved line represents the wave height at each point. A blue arrow denotes the wave direction. Steps to obtain the least time track.

It is necessary to draw a straight line connecting the ports of departure and arrival (Dimitrakiev, Gilev 2021). The thick blue line between the red dots represents the shortest possible sailing distance.

The plastic sheet-covered diagram is prepared for the following stage of route planning. On either side of the vessel course, 10° and 20° radial lines must be drawn. Say there are five lines altogether that must be followed.

Based on wave direction, wave height, and ship performance curves, the ship position must be determined after 12 hours on watch on these routes. For instance, the ship will travel 120 nautical miles when the waves are abeam and have a height of 6 meters, according to the second radial line to the right of the shortest route. For each of these courses, the time frame needs to be determined.

The least-time track is the first radial line to the left of the shortest track since it is the point of tangency (Figure 2). If possible, the vessel would then follow this course. Currents, ice, fog, load line zones, and navigational safety hazards are among the variables that might make a route impassable.

The least-timed track acquired must be drawn from the ultimate destination red point to the shortest track possible. As with the original course, lines of 10° and 20° must be drawn on both sides of the ship.

After 12 hours on these courses, the new ship positions must be determined based on the wave orientations, wave height, and performance curve. As with the first planning step, this one is repeated.

Weather routing systems are crucial for cruise ships, as they help prevent accidents caused by dangerous weather conditions. This is especially important considering the unpredictable nature of the ocean and the possibility of encountering storms that can cause damage to ships and pose a threat to passengers and crew members.
