what is Navy shipbuilding
art & science
236
problem of training for shiphandlers
warships is low while size is higher. so opportunities to practice ship handling are low. thus.. shiphandling
237
publication by the US Navy Institute
"Proceedings"
238
important thing to remember about shiphandlign
no single shiphandler has firsthand knowledge of every platform
239
what is the most visible sign of command excellence
shiphandling
240
science of shiphandling
ship's physical characteristics and forces that influence her movements
241
art of shiphandling
using known characteristics/forces to move into desired positions
242
what must a novice know about their ship before being given an opportunity to move it
length beam draft at different loads type and number power position of engines rudder type, number, position RPM and propeller pitch to speed rudder angle and turn surg distance type/number/position of mooring lines and anchors
243
disciplines to know when shiphandling
physics mechanics hydraulics METOC math hydrodynamics physics of: energy, power, work, motion, vectors...
244
what is the IMO
International Maritime Organization - HQ London - specialized agency of the UN that does maritime affairs - has adopted 30 conventions/protections and +700 codes on maritime safety
245
SOLAS
Convention on Safety of Life at Sea
246
MARPOL
Convention for the Prevention of Pollution from Ships
247
"Rules of the Road"
COLREGS: International Regulations for the Prevention of Collisions at Sea
248
Seaman's Eye
learned skills of timing and execution of planned maneuvers based on observation of all forces working on a ship - professional ship handler can detect/correct with deviations from a plan
249
tools used in the art of shiphandling
direct from bridge - engine, propeller, rudder, thrust, auxiliary power remote control - tugs, lines, anchor not controlled - wind, current, channel configuration
250
role of the Conning Officer
must plan a maneuver, give appropriate orders, observe if things are going as planned, correct deviations, and repeat until maneuver is completed - MUST understand all forces working on the ship
251
needed to become a shiphandler
1. physical characteristics of the ship 2. technical, scientific, and principles involved 3. forces that affect maneuvering and positioning of the ship 4. full understanding of terminology
252
problem of the fleet communities
too few opportunities to practice. wit your turn - typical 2 year duty = ship makes ~24 pier side landings. (pilots do 20ish, CO/XO 5, so 15 for the rest of the crew. DHs get 6ish so 9 for the remaining O's. few chances for the juniors/new. novices get little chances to get familiarization, competence, and confidence
253
importance of understanding the configuration of a ship
single v multiple screw, single v dual rudder, rudder lined up behind the propellers v offset, gas turbine v steam v diesel capabilities/limitations of bow thruster on aux propulsions units, ships w/high sides and large superstructures are most sensitive to the wind
254
importance of leadership of a ship
should not be ambiguous who is controlling the ship's movements - transfer of the conn is formal so all know who is giving orders, "I have the conn" "Aye Aye" - then announce gyro, compass course, and current order to the engine
255
well ordered bridge
well-ordered bridge is characterized by quiet - Conning O should never have to struggle to make themselves heard
256
MARAD
US Maritime Administration
257
ARPA
Automatic Radar Plotting Aids
258
ECDIS
Electronic Chart Display and Information Systems
259
prerequisite to run a ship
understand all forces that affect the ship and how they interact - understand what can be directly controlled from bridge, controlled by voice command to remote locale, and what isn't under their control
260
forces the OOD on a ship can control via remove communication from the bridge
lines, tugs, & anchors - controllabe forces but not at the same level of precisions as factors controlled directly from the bridge (engine, rudders)
261
affect of water on a ship's motion
water gives resistance to the ship's motion that is proportionate to the square of our speed
262
power to get a ship moving
at rest, very little power is needed to move the ship
263
water resistance to a ship's motion and speed
b/c resistance of water to a ship's motion. increase so steeply with increase in speed, a ship using 1/2 power can make about 80% of its max speed
264
types of ship engines & their pitch propellers
fixed pitch propellers: steam and electronic controllabel pitch propelelrs= gas & turbine
265
shafts of a Navy vessel
Navy vessels have 1,2, or 4 shafts no problem with 3 or over 4 but only Coast Guard Icebreakers use 3 shafts

285
one of the most difficult factors affecting getting u/w
strong wind or current holds the ship to the pier
286
what are anchors designed to do
anchors are designed to dig in w/horizontal pull and break out with a vertical pull - do want tohave some steerageway to lay out chain on a horizontal pull
287
normal technique to drop the anchor
pass a short distance over the point of anchoring (head into the wind/current) then gather slightly sternway to back through the same point so the bow passes over the intended anchorage
288
direction to head in when you drop an anchor
if possible, head into your anchorage directly into the prevailing wind or current (whichever is stronger)
289
what should you always do when you drop an anchor
always buoy an anchor to facilitate their recovery if they slip
290
amount of anchor chain needed
depth of water, time at that anchorage, anticipated weather, characteristics of the bottom most common rule = 5-7x depth of water
291
bow of a ship when anchored
unless the harbor is protected, the bow of an anchored ship moves a great deal - you can dampen this with a second anchor or greater chain
292
why does weather and current matter when anchored?
if anchored in a strong current or weather, it is prudent to maintain a capability to get u/w on short notice
293
how to ease strain on the ground tackle in severe weather
in severe weather, strain on the ground tackle can be eased by steaming in place. - aim = reduce strain not eliminate it. - if slack, then bring up taut. that'll place a shock load on anchor which may cause it to drag or break - if weather is severe enough to consider steaming in place, you'll need a full watch team capable of getting u/w if anchor drags
294
steaming in place
aim - reduce strain not eliminate it. (on anchor) - if weather is severe enough to consider steaming in place, you'll need a full watch team capable of getting u/w if the anchor drags
295
steaming in place
maneuver where a ship uses its engine to maintain its position in the water w/o moving forward - key: no foreword movement but the engine is actively working to counter external forces that cause it to drift
296
key of steaming in place
no forward movement but the engines are actively working to counter external forces that cause it to drift - done to maintain a precise position - engine power and propeller pitch are precisely adjusted to achieve the desired stationary position
297
why would you steam in place?
to hold a precise position
298
what is essential in order to land a ship alongside a precise position
advance planning of maneuver is essential for doing a good job of landing a ship alongside - plan must account for... assigned berth, velocity/direction of wind and current - if you are going pierside or along another ship, if pier is pillon or solid face, potential traffic in channel and position of nearby ships
299
direction that is the hardest to land a ship in
landing stern first is harder than bow first - b/c a ship doesn't steer as well going astern and is lest directionally stable - when backing, the pivot point movest towards the stern giving the rudder little to work with - if you have long distance to the back, you need sufficient steerageway to steer (over 5 knots(( or depend upon twisting with teh engine to maintain directional control -
300
how do you steer around a pier
you need to learn to read the ship's motion fore, aft, and laterally
301
pitometer
reads speed relative to water not solid objects around you
302
important thing to remember about instruments
instruments are helpful but none replace your own observations
303
water when the ship's engines are backing up
quickwater = pattern of disturbance when ship's engines are backing, the water is distrubed by the back screw appears as a swriling pattern on the surface
304
quickwater
= pattern of disturbance when the ship's engines are backing, the water is disturbed by the back screw appears as a swirling pattern on the sur4face 3 knots = quickwater stays with the ship 2 knots = water moves forward onto each side of the ship - as backing engines bring ship to a stop, the quickwater moves foreword to amidshp
305
what are anchors designed to do
anchors are designed to dig in w/a horizontal pull then break themselves off with a verticule pull - when dropping, you want to lay out the chain to put a horizontal pull on teh anchor...with steerageway if possible
306
anchor when in restricted waters
when in restricted water, anchor should be kept read to let go - can help with maneuvering - drop anchor so it drags bottom w/o diggin in OR continue to pay out chain until the ship is sufficiently sowed enough to make it but don't think of anchor as an emergency break. can't stop a massive ship suddenly
307
using the anchor to control the ship
anchor can control the bow when being set onto a pier by the wind or current
308
Med Moore
Mediterrean - method of mooring a ship using 2 anchors to secure the bow w/the stern line or lines to the pier - makes best use of limited pier space in crowded harbors - strong moor w/advantage over nestin in that each ship has its broiw tot he pier but the downside is the possibility of fouling anchors w/adjacent ships (can fix that disadvantage if ships leave in reverse order from where they are moored)
309
goal of the Med Moore
Mediterrean Moore - place anchor 100-150 yds apart on a line parallel to the pier and equidistant on each side of the position the ship will occupy when moored
310
advantages of mooring to a buoy
mooring buoys are always more securely attached than what can be achieved with the ship 0 properly moored buoy remains nearly stationary so reduces the swinging arc of the ship
311
how are ships anchored to an anchor
chain is let out through the bullnose and shackled to the buoy
