The Overall view and usage of podded drive future captured from below article.
2.2.7. Other Technology Affecting Port Services Introducing podded drive propulsion systems can potentially reduce requirements for harbor tug services in port. These high-power azimuthing systems significantly improve ship maneuverability, possibly eliminating the need for tug assist services for berthing. While podded drive to date has largely been limited to cruise ship and ferry propulsion, there are indications that use of the technology may spread to other types of ships, particularly where maneuverability is especially important (see Box 18).
Podded electric drive technology uses a sealed “pod” encapsulating an electric motor directly coupled to a propeller. Electricity from the ship’s power plant to the fully submerged watertight pod is provided via cable. The pod is steerable and provides side as well as fore and aft thrust. Use of the pod eliminates the requirement for a rudder, shaft, and stern thruster and frees up space inside the ship that would be otherwise occupied by a conventional propulsion engine. Currently, the technology is largely limited to cruise ship and large ferry propulsion. However, a survey of shipowners and shipbuilders indicated that podded electric drive has potential use in a variety of ship types. Generally, the results indicate that the technology has greatest possibility on ships where maneuverability is particularly important, space and weight savings have substantial value, or current propulsion systems interfere with efficient layout. Because the ship is more maneuverable, tug assist in harbors may not be necessary, which could affect future requirements for harbor tug services. In addition, the sideways thrust of podded drive could affect the underwater structure of piers during vessel docking and undocking and accepting vessels with this propulsion device may require some beefing up of the berth.

X Bow arrangement
Please prepare case study 450 words based on below guidelines. Importance to be given for the X bow design advantage and difference from conventional design,. You will find useful information from below link and notes taken below from same link.
The X Bow (Axe Bow) ship, with its revolutionary and innovative design, has created quite a sensation when it was introduced to the world. This ship was devised by the Norwegian Ulstein Group that is known for their safe, reliable, and operable designs.
Inspired by the ancient Viking ships, the X Bow, as the name suggests, has a rounded bow with a little flare in the forepart of the ship. This shape along with the increased length of a vertical prow pierces through the water instead of slamming onto the incoming waves. This adds greater buoyancy to the ship, reducing the speed and violent motion, resulting in better seakeeping. The bow with the navigating bridge mounted on top in the forepart makes large room for accommodation, and the rest of this ship is available for cargo.
The following are the advantages of the bow shape:
- Higher transit time
- Reduced fuel consumption
- Negligible slamming reducing the risk of damage to the vessel
- Lower pitch and heave accelerations, and enhanced protection of cargo areas reducing the risk of loss or damage of cargo
- Increased payload capacity for certain applications and configurations
- Improved work environment
- Prevents passenger discomfort, seasickness, and injury
The small and medium sized vessels engaged in regional trades are particularly expected to capitalize on the benefits offered by the X Bow.
The Ulstein AX104 Bourbon Orca, the first vessel of Ulstein X Bow was awarded the ‘Ship of the Year’ for 2006.The advantages of the bow shape are extended to several types of ship such as container feeder ships, open hatch bulk carrier, ro-ro carrier, and general cargo vessels. This design can also be applied to large deep-sea ships over 50,000 tons and also for short sea vessels. The construction costs are also lower as against the conventional ships. The Ulstein Group has made arrangements to incorporate this design for a new class of short-sea shipping vessels also.
The beginnings for this design can be attributed to the late 1990s to the collaboration between Damen Shipyard, a commercial and military vessels builder, and the faculty of Delft University of Technology. The concept they developed was known as the Enlarged Ship Concept (ESC). ESC was refined in the year 2003 with additional participation from the U.S Coast Guard and the Maritime Research Institute Netherlands (MARIN), eventually leading to the bow design. This design was specifically developed to improve the seakeeping at high speed and ensuring 100% operability on North Sea at 50 knots with a 50 (164’) meter patrol boat, according to Jaap Gelling, Product Director of Damen. And an advantageous side effect to this is the reduction in resistance from 10 to 15% in flat water compared to a conventional fast vessel.
- Improved power efficiency
- Soft entry in waves
- Very low levels of noise and vibrations
- Reduced bow impact and slamming
- Reduced wave-induced vibrations
- Improved resting time
- Lower acceleration levels
- Lower pitch response due to volume
- More comfortable on board conditions
- Lower speed loss
- Reduced spray
ICE CLASS A
Please prepare case study 450 words based on below guideless. Stress on wht we need Ice class design advantage and additional structural work to sustan ice water saailing,. You will find useful information from below link and notes taken below from same link.
Ice class refers to a notation assigned by a classification society or a national authority to denote the additional level of strengthening as well as other arrangements that enable a ship to navigate through sea ice. Some ice classes also have requirements for the ice-going performance of the vessel.
Beginning this last section of our series, we delve into the design considerations of an ice-capable ship. Now an obvious question arises is that is there differences in design amongst icebreakers, ice-going and ice-class ships? The answer is, yes.
However, to put it simply, the best way to avoid the confusion is to hierarch these three in the sense that an icebreaker requires most of the ice-breaking capabilities, as they are dedicated to the function of breaking ice and often escorting other vessels in ice-clad waters, followed by ice-going and ice-class, as described in the previous article .
Ice-class/ice-strengthened vessels have a significant difference between icebreakers and ice-going as they are general-purpose ships with capabilities to tread in icy water conditions with an escort like an icebreaker, remember? So they lack several functional and design capabilities of the other two. We briefly summarize ice-class ships in our last and concluding section as they do not have huge intricacies in their hull form.
Reiterating back from our previous article, the hull form design of an ice-capable ship takes into consideration parametric angles in terms of stem angle, flare and waterline entrance angles
The hull form of ice-going ships including icebreakers has always been a debated topic. Over the years, the hull form has undergone several evolutions, transitions and developments to enhance icebreaking and negotiating performance without compromising propulsive efficiency.
Discussing the history of all those developments is time-consuming and may be referred to in trusted resources if required. But the crux of designing a suitable hull form for ice ships lies in the aim for reducing the overall ice resistance while effectively breaking and clearing ice.
As we know, ice resistance due to crushing is several times higher than due to bending by shear loads. So, the main aim is to reduce this ‘crushing’ resistance as much as we can. Also, the open-water resistance (mostly frictional) is also not compromised. So over the years, from experience and theoretical analysis, the hull form of ice vessels form various countries have evolved significantly in different countries.
Factors affecting the design of ice-capable ships are as follows:
- Ship’s beam
- Ship angles
- Hull condition
- Ice condition
- Service of the vessel
