问题 1 从 80

When handing over the con of a vessel to a pilot, should the Master insist in discussing the passage plan with the pilot while he is there to use his local knowledge and advice on the navigation of the ship?

A passage plan should be discussed between the Master and pilot, when under pilotage in the same way as discussed with the bridge team when deep sea.

A pilot is responsible for the navigation whilst on board and will be very familiar with what is required, therefore discussing the passage plan is not necessary.

The pilot would probably consider it unnecessary, be more interested in knowing the ship’s characteristics and resist any passage planning discussions with the Master.

The passage is well established and known by the pilot and a plan is therefore not necessary.

What significant change to the requirements for the carriage of Vegetable Oils in tankers was introduced by the amendments to MARPOL and the IBC Code on 1st January 2007?

They must now be carried in double-hull tankers.

They must now be carried in type II tanks.

Your chemical tanker is fitted with sumbersible deepwell cargo pumps. When stripping a tank, if excessive air is allowed to be drawn into the suction line, which of the following may occur?

The pump will “race” and there will be a loss of suction.

The cargo pump impeller will stop rotating.

The back pressure will increase.

Control of the operation will be lost and the tank will rapidly empty.

Onboard training should be organised in such a way that:

It is an integral part of the overall training plan.

Each crew member is trained individually.

It does not contravene with the rest hours of the crew.

None of the above.

A conventional tanker has most of its tanks slack during the discharging of oil cargo, it is not of any great consequence; however, if an OBO has most of its holds slack during discharging (or loading) of oil cargo this will:

Likely cause a sudden or violent list due to the very large free surface in the broad beamed holds?

Cause extreme strain to the hull on the listed side if a list develops?

Cause the vessel to develop a slow rolling motion?

Have not much effect on stability as these vessels are designed for such conditions?

“Passivation” is a restorative process periodically applied to stainless steel tanks on a chemical tanker. What effect does this process have on the steel surface?

It restores and reforms the passive Chromium Hydroxide surface layer.

It restricts active corrosion on the surface steel.

It restores the surface steel to an even and smooth finish, thereby encouraging drainage during discharge.

The carriage of a new Noxious Liquid Substance not yet listed in the IBC Code may be considered possible, provided it is achieved through a “tri-partite” agreement between:

Call the Master.

A tanker in ballast, having recently left the discharge port is involved in a collision. The two vessels are still interlocked after the collision and a survey of the ships gives all crew members are safe and the damage is focussed to the vicinity of the impact. What should be the greatest concern at this time?

The ships moving together in the swell/seaway will cause a spark and consequently an explosion.

The possibility of pollution.

The vessels moving together will create even greater damage to their structures.

When the two vessels separate, one (or both) of the vessels will have insufficient stability to remain afloat.

The “dew point” of a liquid chemical can be defined as:

The temperature at which a saturated gas exhibits condensation.

The temperature at which dry-ice melts in Acetone.

A report giving the result of the Performance Test, issued by the manufacturer in compliance with the Flag State Authority requirements.

A report giving the result of the Conformance Test issued by an Application Service Provider on behalf of an Administration.

When a Master takes the leadership in approaching a problem, must hist first action be a decision that will directly solve the problem?

Not necessary, he shall use all available resourses. He should resist the temptation to step in and do it all by himself.

As per IMDG Code, the term “separated from” can be defined as:

In different compartments or holds when stowed “under deck”. Provided an intervening deck is resistant to fire and liquid, a vertical separation may be accepted as equivalent. For “on deck” stowage, this segregation means a distance of at least 6 metres.

Either in a vertical or horizontal separation: if the intervening decks are not resistant to fire and liquid, then only in a longitudinal separation is acceptable. For “on deck” stowage, this means a distance of at least 12 metres. This distance also applies to one package stowed “on deck” and another in an upper compartment.

With an intervening compartment, being both a vertical and horizontal separation. Provided an intervening deck is resistant to liquid and fire, a vertical separation of 6 metres is acceptable. For “on deck” stowage, this segregation means a distance of at least 12 metres irrespective of compartment divisions.

Effectively segregated so that the incompatible goods cannot interact dangerously in the event of an accident, but may be transported in the same compartment or hold or on deck, provided a horizontal separation, projected vertically, of 3 metres is obtained.

The subject «Deck Department, Management Level, Chemical Tanker» covers both theoretical and practical knowledge about safely working with electrical equipment, which is a key indicator of an employee's competence in their role aboard a vessel. As a Deck Officer on a Chemical Tanker, the role involves a variety of responsibilities related to deck management. The primary duty is to oversee and coordinate the safe and efficient loading, unloading, and transfer of chemical cargo. This requires a thorough understanding of the chemical properties, handling procedures, and stowage requirements for each type of cargo, as well as ensuring compliance with all relevant regulations and industry standards. Additionally, Deck Officers are responsible for the safe navigation of the vessel, which includes planning and executing the vessel's route, maintaining its position, and adhering to all navigation regulations. They are also tasked with watchkeeping, maintenance, and ensuring the overall safety and security of the vessel.
