What ship furnishes the rigs, including the shot lines, station-to-station phone line and rig messengers?

The delivery ship

What ship will hand tend all pone lines?

When will the delivery ship send and hand tend all phone lines?

When the receiving ship has complement of 50 personnel or less.

When 2 ships are delivering to each other and the weather is rough, what ship is it more desirable to be the approach ship?

The more maneuverable ship

When replenishing, what is required to maintain station because of the forces that act upon both ships?

Precise maneuvering and particular emphasis shall be placed on steering control and coordination between ships

Who is responsible for selecting and promulgating the replenishment course and speed?

The OTC

When ready to receive a ship alongside, what ship hoists ROMEO close up?

The control ship, at night, ROMEO close up shall be signaled by flashing light or voice radio

What does the approach ship do when ready for UNREP at the designated stations?

Commences the approach and hoists ROMEO close up. At night, ROMEO close u shall be signaled by flashing light or voice radio

Who attains proper for and aft position alongside by observing the appropriate ship structure?

The conning officer on the bridge of the approach ship

At what stage is there a risk of collision during the approach, unless lateral separation is adequate?

When the bow of the approach ship passes the control ship

Why should relative speed be reduced when replenishing in shallow water?

Shallow water increases the effect of the differential in water pressure, which can cause the approach ship's bow to veer in toward the control ship

How can the approach ship make a wider approach than would normally be required using the gyrocompass?

Steering by magnetic compass

What is the minimum required during initial tensioning?

140 feet

What can result if separation distances between delivery ship and CVN is greater than 180 feet?

It may result in unseating the lower probe of double probe rig

What is venturi effect?

There are areas of increased water pressure at teh bow and stern and areas of decreased water pressure (suction) amidships. The venturi effect results from the differences in velocity in the flow of water around the hull

When ships of the same size are alongside, what is their best position?

Exactly abeam

When ships are alongside, and the approach ship is considerably smaller than the control ship, what is their best positions?

In between the bow and stern pressure areas.

Except in wartime or in an emergency, ships will not operate underway alongside unless the depth of the water is how many times the draft of the ship with the greatest draft?

At least three times the draft.

During a replenishment operation, and prior to going alongside, steering control should be checked in what mode?

In all modes of operation, in accordance with applicable maintenance requirement, from both the pilot house and after steering.

Whenever feasible, during a replenishment operation, who is assigned as ship control safety officer on the bridge?

A commissioned line officer or licensed officer

Who is assigned as after steering safety officer?

An E-6 or above, and whenever feasible a commissioned line officer should be assigned

What factors determine the rudder angle necessary for maintaining station alongside?

Size and loads of ships, sea and wind conditions, replenishment speed, distance between ships, location of transfer station and transfer rig employed

When a STREAM rig is used, who makes the recommendation on a minimum distance between ships considered safe for the receiving ship when tension if first applied?

The conning officers of both ships

After all STREAM rigs have been tensioned, the conning officer of the control ship may need to carry what rudder angle to maintain the prescribed course?

Some degree of relatively steady rudder angle

What does the need for and the degree of rudder angle that the receiving ship carries depend on?

The location of the STREAM receiving station relative to the ship's of rotation (pivot point)

When loss of steering control is reported or sounded, what should the commanding officer and conning officer determine as quickly as possible?

The position of the rudder and direction the ship is heading in relation to the replenishment course, before automatically giving a rudder command.

The conning officer of the approach ship shall conn from what position?

Where that ship's heading, the rudder angle indicator if installed, and the relative motion of the two ships can be observed.

What flag hoist signal should the approach ship hoist, when disengaging at the last transfer station?

Prep close up.

When does the approach haul down PREP?

When all lines are clear

During underway replenishment, what is the objective of an emergency breakaway?

To disengage quickly without damaging the rigs or endangering personnel

What are some conditions of an emergency breakaway?

Engineering casualty, enemy contact reported, emergency launch or recovery of aircraft, when hoses appear in danger of parting, when a rig pats and a possibility of the screw becoming fouled, and when a person is lost overboard and a lifeguard ship or helicopter is not on station

Who can order an emergency breakaway?

The Commanding Officer of either ship

What should be the primary means of communication for ordering an emergency breakaway?

Sound-powered phones, bridge-to-bridge radios, and hand signals, because of the minimal amount of noise generated. However, the general announcing system (IMC), bullhorns and voice radio circuits can be used to ensure rapid ship-to-ship communications

What is the danger signal sounded by the ship initiating the emergency breakaway to alert all ships in the vicinity?

At least 5 short blasts.

In sounding five short blasts on the whistle to alerts ships in the vicinity of emergency breakaway, what due regard should be taken?

The tactical situation, the effect of increased noised levels on conning officers-to-helmsman communication and the disruption to intership and intraship sound powered phone communications caused by whistle signals

Once an emergency breakaway is initiated, what ship will assume control and initiate proper hand signals with appropriate parallel information of radios or sound powered phones to the receiving ship?

The delivery ship

What is paramount in execution of an emergency breakaway?

The allowance of sufficient time for the ships to disconnect the rigs in a safe and orderly manner

When a condition warranting an emergency is recognized, what actions should be taken?

Notify the intraship stations, pass the word between ships, stop all transfers, retrieve rigs, and sound-powered phones remain connected until rigs are disconnected and all lines should be released by the receiving ship

When a condition warranting an emergency breakaway is recognized, what intraship stations should be notified of conditions or situations?

Bridge, cargo control center, fuel control center, fueling stations, and cargo stations

If the gyrocompass falls, why is steering by magnetic compass NOT the best alternative?

Changes and deviations in readings from the magnetic compass, because of the ships alongside and their relative movements and the low sensitivity of the magnet compass to small changes in heading, suggest that there are times when positive control can only be obtained by using rudder orders

What is the basis for proper preparation for personnel involved in replenishment?

The assignment of specific duties to personnel at each UNREP station. Personnel shall be thoroughly briefed on the entire evolution prior to each UNREP.

What shall personnel assigned to use velocity, pole-type, wire ripe cutters be trained and certified in accordance with what directive?

OPNAVINST 8020.14 (series), Department of Navy Explosives Safety Policy.

How shall winch watchers stationed at winches used during replenishment report any malfunction immediately?

By blowing on a whistle loudly until acknowledge by the rig captain or winch operator

On ships using wire rope rigs for underway replenishment, how is each wire rope end secured to the winch drum?

By only one wire rope clip or specially designed clamp that will allow the bitter end of the wire rope to slip free of the drum during an emergency breakaway

When are the explosive-charged velocity pole type wire rope cutters used?

To cut non tensioned wire ropes and lines during an emergency breakaway if there is danger to the ship's structure

How many explosive charged velocity pole type wire rope cutters are required at each STREAM solid cargo transfer station on an UNREP delivery ship?

two

After station to station communications have been established, what should be reviewed by the safety officer at each transfer station on th delivery ship and the corresponding safety officer on the receiving ship?

In detail the procedures for an emergency breakaway. The delivery ship shall send over with the first lines at each station written instructions for breakaway applicable to the rig being used

During the replenishment operation, when shall preparation be made for an emergency breakaway?

Upon receipt of the first line
