According to the studies of Chase, stated in the book “Principles of Naval Architecture”, when clearing a ship slip, what is the adequate criterion for judging backing speed with respect a ship’s operators (Pilot included) opinion:

Associe os termos náuticos da coluna A) com a coluna B), com relação aos termos náuticos referentes aos cabos e sua manobra, de acordo com Maurílo M. Fonseca, no livro Arte Naval:

COLUNA A

1) Desgurnir

2) Desengastar

3) Engasgar

4) Enrascar

5) Recorrer

COLUNA B

( ) Retirar cocas.

( ) Desfazer uma coca que tenha mordido no gorne de um poleame.

( ) Deixar que arriem os cabos ou a amarra para aliviá-los.

( ) Embaraçar cabos entre si, de modo a impedi-los de trabalhar regularmente.

( ) Passar um cabo por um gorne ou retorno, impedindo-o de correr.

( ) Tirar os cabos de laborar dos lugares onde estão trabalhando.

Pilot Gabriela needs to reduce as fast as possible the speed of a ship with 16 knots, in an emergency situation. The lateral sea room permits all available maneuvers. What is the better maneuver to be executed by Gabriela, as function of ship’s actual speed, according to “Principles of Naval Architecture”?

A vessel is considered to be "restricted in her ability to maneuver" under the Rules of International Regulations for Preventing Collisions at Sea, 1972 – COLREG if she is __________.

Which statement concerning reserve sources of energy for GMDSS is FALSE?

Na interpretação de uma carta sinótica de pressão ao nível do mar, o navegante identifica em uma região de ocorrência de cavado, no oceano Atlântico Sul, uma área com vento forte de SW, quando observa-se, de acordo com Lobo e Soares, no livro “Meteorologia e Oceanografia”, as seguintes características:

Atualmente, a força de tração nos cabos de reboque tem levado à ruptura de cabeços e buzinas de navios. Este fato, Otávio e Marcelo, no livro “Rebocadores Portuários”, do CONAPRA (Conselho Nacional de Praticagem) tem se tornado perigosamente freqüente, principalmente em operações de escolta. O aumento de freqüência desse tipo de acidente levou a OCIMF (Oil Companies International Marine Forum) a

preparar um documento recomendando, entre outras normas de segurança, que exista uma troca de informações entre o Prático e o Comandante do navio. Esta recomendação está no Anexo 4 do livro supra citado. Coloque F (falso) ou V (verdadeiro) nas afirmativas abaixo, sobre o que é recomendável que o Prático avise ao Comandante do navio, de acordo com a OCIMF, assinalando a seguir, a opção correta:

( ) If escorting, the maximum towline forces that the tug may generate at escort speeds.

( ) The type of rugs to be used and their bollard pull(s).

( ) Which chocks, bollards and strong points can be used for towing.

( ) The method by which the ship’s crew should take on board and release the tug’s tow line.

( ) The SWL (Safe Working Load) of the mooring fittings.

( ) Maximum planned speed for the passage and the maximum speed of the tug.

( ) That on release, the tug’s gear should be lowered back always under control.

Captain Crenshaw, in his book ”Naval Shiphandling”, states that “Shiphandling is the art of handling the velocities of aship”. So, a pilot uses forces of engines, propellers, rudders, the wind and the tide, lines, tugs and anchors to control the velocities of a ship. One of the most important sources of force on a ship is her own propeller and the pilot must understand the action of a propeller in order to be able to predict its action on ship. A propeller produces side forces in addition to thrust along the propeller shaft. A ship can rotates to starboard or port as function of these side forces. Pilot Antonio is studying propeller side force, on a single right-hand screw propeller, and knows that it can be broken down in four parts: following wake effect, inclination effect, helical discharge effect and shallow submergence effect. Antonio wrote the following consideration:

I) The following wake effect produces a net force tending to move the stern to right and cause the ship to veer to the port.

II) The inclination effect is net effect that tends to twist the ship to the right.

III) The shallow submergence effect tends the stern to starboard and cause the ship to veer to the left.

IV) The helical discharge effect tends to turn the ship to the right.

From the list of Antonio is correct to affirm, according to the book “Naval Shiphandling”, that:

Assinale a afirmativa correta, com relação a nomenclatura do navio, de acordo com Maurílio M. Fonseca, no livro Arte Naval:

Qual das manobras padrão, abaixo relacionadas, indica a habilidade que o leme tem para governar o navio, de acordo com os “Princípios da Arquitetura Naval”:
