CBT Test Online for Seamen about Stability II, Damage Stability

Welcome to the website where you can pass online the CBT test on the subject «Stability II, Damage Stability (CD Module 0061)». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. CBT based on practical information and marine specialists experience.

CBT tests developed for evaluating seaman basic knowledge by Seagull Company (rebranded as «OTG»), is an evaluating online-tool, used for revealing any professional preparation needed in specific fields of knowledge, defined by STCW.

CBT tests have proven themselves as good tools for the selection and recruitment process, as well as advancing the level of knowledge of the current officers and crew. Ocean Technologies Group use various subjects for question creation, which includes:

Crowd and Crisis Management;
Integrated Navigation System (INS);
Ballast water management;
Handling and Stowage;
Vessel operation management and safety;
Marine engineering;
Maintenance and repair, etc.

Current test contains Seagull CBT questions on the subject «Stability II, Damage Stability». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.

«Stability II, Damage Stability» subject includes theoretical and practical information about advanced training for work on any type of vessel. The test evaluates knowledge of intact and damage stability principles for various vessel types. It includes theoretical questions on stability criteria, regulations (e. g., SOLAS), and damage control procedures. Practical scenarios assess the ability to calculate stability parameters after flooding or hull damage. Questions may cover watertight compartments, subdivision and the impact of free surface effect. The test examines understanding of IMO requirements for stability in damaged conditions. Candidates must demonstrate proficiency in using stability software or manual calculations for emergency situations. Case studies simulate real-life damage scenarios, requiring corrective actions to maintain vessel safety. Successful completion ensures competence in assessing and managing stability risks on passenger, cargo and special-purpose ships.

On this site Crew Evaluation System Test on the subject «Stability II, Damage Stability» contains 13 questions you need to answer with no possibility to go back to previous question. Therefore, we recommend carefully reading each question and making decision with no hurry. In case you have some difficulty answering, you have also possibility to request a hint.

What is the minimum required righting lever for a damaged passenger ship at final state of flooding?

0,15 metres.

0,10 metres.

0,05 metres.

0,20 metres.

What is the minimum required residual dynamic stability for a damaged passenger ship at equilibrium?

0,010 metre-radians.

0,020 metre-radians.

0,015 metre-radians.

0,025 metre-radians.

Which statement is true about volume permeability? (Select all applicable answers)

If the volume permeability is 100 %, the damaged compartment below the waterline will be completely filled with water in case of damage.

If the volume permeability is 0 %, no water will enter the compartment in case of damage.

Volume permeability affects only the air flow in undamaged compartments.

Volume permeability determines the speed at which water drains from the ship.

In the added weight method, the free communication effect in damaged condition:

Reduces the GM and decreases the dynamic stability by sinus correction of the GZ curve.

Increases the GM and improves the dynamic stability.

Has no impact on the stability calculations.

Causes the ship to heel permanently to starboard side.

Which statements are true concerning the loss of Buoyancy method: (Select all applicable answers)

The method is suitable for computer programming.

It assumes the ship is undamaged and fully operational.

The damaged compartment is considered non-existing.

The method ignores water ingress and focuses on hull strength.

Which statement is true about the metacentric radius?

The distance between B and metacentre, depending on the displacement and the moment of inertia of the waterplane area.

The vertical distance between the keel and the waterline.

The total volume of the submerged hull below the waterline.

The length of the ship from bow to stern.

Which of the following statements are true, with respect to change of stability parameters for a damaged ship?

Only B moves while M and GM stay constant.

M moves, B moves and GM increases or decreases.

GM always increases after damage.

M and GM remain unchanged regardless of damage.

What is usually the effect on G when the ship is damaged?

It is unchanged.

It increases.

It decreases.

Which statements are true concerning the added weight method: (Select all applicable answers)

It is a suitable damage stability calculation method for manual calculations.

The free surface effect from the water in the damaged compartment has influence on residual stability even though the damage is symmetrical.

It is not applicable for large vessels.

It requires complex computer simulations.

It is only used for theoretical calculations.

Which of the following statement(s) are true?

A damage control plan shows the boundaries of watertight compartments and openings therein.

Cross flooding arrangements are only used in emergency situations.

Cross flooding arrangements reduce the heeling angle in damaged condition.

A damage control plan is not necessary for small vessels.

Cross flooding arrangements can increase the risk of capsizing.

What is the minimum required righting lever for a damaged passenger ship at intermediate state of flooding?

0,05 metres.

0,10 metres.

0,15 metres.

A ship has VCG = 9,80 m above keel. The metacentre position above keel varies according to the hydrostatic table shown here. What is the maximum permissible draught for the ship to fulfil the stability requirements?

6,5 m.

7,0 m.

8,0 m.

What is the minimum required GM for a ship with the following GM(min) curve and draught 6,3 meters?

1,7 m.

1,5 m.

2,0 m.
