Bulk ship 3 Placement and Structure

In bulk carriers, it is relatively difficult to secure a dedicated ballast tank with a large capacity because ships transporting coal, grain, etc.,

which have a large cargo coefficient, need to make the cargo hold as large as possible so that they can load a lot of cargo.

As a result, there is a shortage of ballast when operating an empty ship. As a countermeasure to this problem, a specific cargo hold is often used as a ballast tank.

Since grabs or bulldozers are often inserted into cargo holds to unload bulk cargo ships, protrusions should not be installed on the double bottom inner bottom, and hatches should be made as large as possible to facilitate mechanical unloading. .~

General bulk ship

Above Fig is a general bulk cargo ship layout. ~ It is important is the top side wing tank also plays a role in preventing grains from accumulating on one side.

ore carrier

The ore carrier does not have a top side wing tank as shown in the drawing above. Instead, it has large ballast tanks on both sides.~

In the case of ore-only carriers, the cargo hold does not need to be large in order to load iron ore with a large specific gravity, so sufficient dedicated ballast tanks are secured, and there is a need to increase the double bottom to ensure sufficient strength of the double bottom.

ore and oil tanker

Ore-cum-oil tankers have the characteristic of being able to handle both solids and liquids.~

Ore and bulk tanker

Basically, in the case of ore and bulk oil tankers, it is almost impossible to see them ~ They may be floating on the sea ~ That is how unique they are ~ They can perform many functions, but they are not efficient because they do not carry a lot of cargo, so ship owners do not prefer them ~

Bulk 4 Structural Terminology and Forms

Structural terminology and forms. First, this is the structure of the hold part where cargo is loaded. Typical Cargo Hold – single side skin There is a top side wing tank to prevent cargo from stacking and tilting. The hull shell is vertically reinforced with T-shaped webs (at regular intervals). The hopper tank is tilted at a 45-degree angle to avoid concentrated loads and makes loading and unloading of cargo easy. Also, cleaning is easy because it is tilted ~ The cargo floor is double bottom~ Typical Transverse Section The picture above shows the inside of the cargo window in section. Each term is written down. The form of the structure is to use a tank by blocking the upper edge of the cargo hold with an inclined plate (top side tank), and to allow the side cargo to easily flow down, a hopper is installed by attaching inclined plates to the corners of both sides of the cargo hold floor. The hopper has almost double the strength. It has the function of reducing...

Class Notation - Dr Choi shipbuilding cafe

When a ship contract is signed, a notation is inserted into the contract. This time, we will organize the contents of these notations. First, the notations defined by the classification society are as follows. They indicate that the ship or facility has met certain essential requirements for the classification and are listed in the Class regulations related to each rule set. Class notations describe the structure or characteristics of the ship and are supported by technical requirements of the rules that can be clearly complied with. Sometimes, compliance with the rule requirements can be achieved by satisfactorily following ShipRight procedures (e.g. FDA, there may be other ways to demonstrate compliance with the rules). It is important to keep in mind that not all aspects of the Class Notation requirements are based solely on an evaluation of the ship plan against the rules, and many verifications are performed on site with the presence of an inspector. This is where the term S...

US shipbuilding revival policy, a 'double-edged sword' for Korean shipbuilding- Shipbuilding Maritime Story 2025-03-07 Dr. Choi's Shipbuilding Cafe

● US shipbuilding revival policy, a 'double-edged sword' for Korean shipbuilding: Coexistence of opportunities and threats Recently, as the US government has been promoting various policies aimed at revitalizing its own shipbuilding industry, a 'double-edged sword' situation is unfolding in the domestic shipbuilding industry. Expanding entry into the US MRO market As the demand for maintenance and repair of aging naval vessels is increasing in the US, domestic shipbuilding companies can gain opportunities to enter the US MRO market based on their high technological capabilities. In fact, major domestic shipbuilding companies such as HD Hyundai Heavy Industries, Hanwha Ocean, and HJ Heavy Industries have begun preparations to participate in the US naval vessel MRO business. Expectation of an increase in orders for high value-added ships The US is expanding investment in high value-added ships such as eco-friendly ships and smart ships, so domestic shipbuilding companie...
