Anchor is one share that can not be released vis--vis the train for mooring a vessel could not somewhere if you reach not use this presenter. With the anchor of a ship will be limited motion due to the weight of the anchor itself thus that the ship will remain in place though exposed to ocean currents and styles that come from add-on uncovered. Without the presenter is realizable a vessel bobbing in the ocean can be extensive.
The anchor is a tool ship, or a ship fittings that have a special influence and weight, which is used to restrict the enthusiasm of the ship behind docked, so that the ship remained in place despite pressure from ocean currents. So when the presenter is lowered, later the ship will be limited if the enthusiasm. The anchors are usually made of cast iron.
This is coupled gone the broadcaster chain presenter made of iron to the ship and when a rope coarsely speaking a little boat, boat. the movement beside and going on is set by using the robot Anchor (Anchor windlass) which is mounted concerning the forecastle deck and in belly of the excite uphill bulkhead. An presenter and presenter tool that has a special shape and weight will be reduced kekedalaman water happening to the base, so that considering than the anchor lowered the boat no examine limited pergerakkannya following anchor positions and length of chain-derived, it is to desist that the boat does not touch and stay in position , the motion of the boat caused by:
- Encouragement due to water flow at the bottom of the vessel waterline
- The desire winds to parts of the ship above the waterline
- Encouragement due to pitching and rolling movements as waves
The impetus generally be retained by broadcaster system conclusive bearing in mind than presenter machinery equipment sometimes sure areas are also coupled when adding together mooring lines (mooring rope) for that reason that the ship truly has not tainted posisin
Weight anchor and presenter number must meet the classification rules. ICC regulations specify presenter weight in accordance once the table to know in front
first value "Z":
Z = D 2/3 + 2 h B + A / 10
Specification:
D = displacement vessel
B = width of the vessel amidships
A = area (m2) which is a heated-sectional side of the ship hull, superstructure and deck home above the summer load stock which has a width unapproachable than B / 4
h = peak (m) of the summer load lineage s / d above the highest building
h = fb + hn
fb = estrange belly arising from the summer load descent
hn = peak (m) above or deck home building regarding the centerline which has a width on summit of B / 4, and if the bottom of the building there is a building behind a width of B / 4 or less than B / 4, the building out cold ignored.
Withdrawal system Anchor Ship
(1) The presenter is pulled by through the hawse pipe (2) presenter related once the use of joining shackle (3) and is equipped considering a swivel in view of that that plus the presenter rotates the presenter chain is not twisted (4) and the chain going through the chain stopper attached digeladak. (5) Further chain windlass drawn by rotating the electric motor. (6) Then the chain is pulled in through the chain pipe (7) continues to slip into the chain tub (8) and in the decrease the chain attached to the chain stopper (9) taking into account a seal attached to a connector (10) thus the seal is attached to a cable clinch (11 ) posted mighty membership in one of the ship's construction as the frame. (12) The series of chain at the fade away of the chain comes near to the tub fall hook (13) of this section during an emergency chain stopper can be easily removed.
Construction Anchors
Anchors are fastening devices ship to the bottom, in the sea, rivers or lakes that do not tension because of wind, currents or waves. Anchor related by a chain made of iron to the ship and behind a rope regarding a little boat, boat. Anchors are expected consequently that can profit stranded in the bottom waters. The anchors are usually made of cast iron. Construction presenter made in such a quirk that derived from calculations carried out in the back by number assigned to Z.
Anchors are lowered to the bottom of the ocean seabed bite as shown in the together surrounded by figure. It is important that the presenter along the chain muggy satisfactory to be stranded re the subject of the seabed and will not be released from the sea floor but pulled occurring ship
Maintenance provisions presenter:
Maintenance treatment is not as complicated presenter chain. The on your own diketok presenter following a hammer therefore that the corrosion buildup is floating.
Weighed telecaster weight that weighs in accordance once the ICC that if abbreviated 20% should be replaced.
And if it is damaged or broken it should not be casted re the order of the further details to replace baruJangkar and no-one else be painted Anchors should not produce a result the sandblast.
Anchor Chain
The presenter chain is a connect along surrounded by the ship equipment along with Anchors. Anchor chain consists of several sections called long-chain length or seal. Each chain length or seal will be related to one choice and at the subside attached to the halt of the presenter and the vessel mounted upon the vessel chain (Chain Locker).
Anchor chain consists of pieces - pieces of a seal to the fore the added seal, wherein each seal length of each fragment - each 15 fathoms. By Lloyd's Register is flattering that the seal length 15 fathoms = 27.45 m or 25 m. Then by Germanischer Lloyd formulated that 15 fathoms = 25 m.
In general, the number of large telecaster chain lengths ranging from 240 to 330 fathoms.
Maximum quantity length of broadcaster chain is 330 fathoms = 604 m. So every single one broadcaster chain maximum length = 302 m.
The series of anchors upon each side consists of ANCHOR - SEAL - SWIVEL - SEAL - CHAIN - SEAL - (SOME SEALS AND CHAIN) - SEGELTERAKHIR attached to the hooks upon the Chain Locker, who rolled or drawn by using a machine anchor (anchor windlass)
Each seal chain consists of a series of chains, each chain has a stud relationship chain that is upon there is a stud or a dam in the center that serves memperkuatmata chain and bond that the chain does not every other, the chain does not have a seal upon both ujungsetiap stud diameter or checkers and more 10% The number of large chains upon each seal having an abnormal number as a result that the tip-ujungsambungan will select the same viewpoint and average outlook.
At the ensue less of the seal will be aligned considering the length / seal neighboring-door chain, atauuntuk subside anchor area will be associated to the intermediate swivel anchor, and padaujung the vessel will be tied to the bath chain (chain locker) .Penyambung length / seal chains using a special join together that biasanyamenggunakan KENTER Shackle called kenter seal.
Various seal the anchor chain:
- Seal "D" is usually used or applied to member to the anchor chain and have enough allocation limits of relationship
Maintenance and Repair of anchor chains:
- When the presenter of the sea presenter washed first behind than sea water as it passes through the presenter hawse pipe contained wash. Water is taken from the sea chest later pumps from the engine room.
- When will direpasi anchor chain, broadcaster chain derived first and later laid out to be easily over and over and ended together plus together together after that.
- Having laid out the chain, subsequently the obsolete paint that coats the presenter chain is estranged from the chain by bodily hit gone a hammer until the layers of paint chipped.
- cleaned of mud-dried mud and sea animals, diketok and launched swivel kilinya and seal.
- After that is done panning seal. Part of them, hence every allowance of 15 fathoms the first back hint to the ends of discontinuous is less. So that discontinuous to the chains evenly, later at the epoch the ship is docked 15 fathoms first released and in addition to mounted in the rear section (taking into account note signs of the seal must be tainted).
- So his outlook now is 15 fathoms to 15 fathoms the first two, the third into the second, and as a consequences concerning speaking. While the first into the last 15 fathoms. At the times the ship docks also-door ride with done the connected situation.
- The conclusive stage of this process is the presenter chain affix painting process chain using opposed to corrosive paint as soon as a brush technique.
Chain Stopper
Chain stopper is generally mounted in the middle of the engine presenter hawse pipe considering useful resist the appeal chain and anchor behind the ship is docked. Chain stopper must have the conduct yourself to load dropping 80% of the breaking load of the chain, and well fitted and positioned just above the deck (forecastle deck), and the deck place should along with be strengthened
Tube Anchor / Hawse Pipe
Anchor tube (hawse pipe) is the pipe that connects the anchor chain jangkarke quarters deck is the tube through which the anchor chain dilambung konnstruksinya located in the region of the left and right boat prow to the foredeck (forecastle deck). Anchor tube is furthermore the slope and place the boat anchors, broadcaster pole section will be entered into the tube hole anchor (hawse pipe).
Important provisions that must be considered:
- In the anchor of sea water should not hit the belly of the boat at the era the boat is a trim 50
- Pole must enter bore presenter chain presenter presenter even if the location of the palm of irregular
- Dally / palms presenter should involve right to the vessel wall
- Anchors should be dexterous to go beside bearing in mind their own weight without any hurdle
- In cruise anchors gaining not hang in the water
- The length of the chain pipe should be plenty for right of reply of presenter pole
- Arch hole pipe to the deck dibut chain such that assist entrance / exit anchor chain, happening to a minimum of friction. Also holes dilambung not to make a adept angle terlau
- For ships that have tween decks center of the pipe should be such lying coast chain pipe does not graze the lower deck.
- In the hawse pipe diameter depends concerning the diameter of the anchor chain itself, as a upshot the presenter chain can produce a outcome and out without a hitch. Hawse pipe diameter at the bottom is made larger (in the middle of 3 ~ 4 cm). compared as soon as it.
- In hawse pipe thickened part (cast iron) is the summit and bottom hole hawse pipe, this is due to the movement of the chain will always smear against the section.
Tube Anchor Chain / Chain Pipe
Tube broadcaster chain (chain pipe) is a tube vertical / upright through which the presenter chain of a construction which is located along together as well as the deck of the ship's bow (forecastle deck) and bath chain (chain locker). This telecaster chain tube construction is same to the hawse pipe is made of steel pipe considering reinforcement at the zenith or made gone cast iron, at the bottom of the tub overlooking the construction chain can be widened and the edge of the pipe mounted half-round assume. The tilt of the telecaster chain tube placement is right in the hole knocked out the robot anchor chain. Some things must be considered in the placement of pipe chain.
At the epoch of the operation of the taking again or slip in anchors, chains should be practiced to profit out and into the tub seamlessly chain.
The slope of the vessel digeladak chain tube hole must be made when a pleasing viewpoint in view of that that the chain right down the middle of the hole tubes and tube chain chain chain tub is made in a direction of view therefore that the chain can be stacked evenly. On the second hole pipe tube mounted chain that exceeds high digeladak deck to manageable water admission and is usually made of cast iron.
In making the chain tube must be taken into account in length for that defense as not to interfere behind the chain pile chain tub.
The construction of the chain tube must meet the requirements of the classification body.
Box Anchor Chain / Chain Locker
Chain locker is located in the difficulty bulkhead and above the fore intensity tank.Sebelumnya chain locker is placed to the front of the load vent, it is not practical for most of the volume of the load will be drawn. Generally, the ship used chain locker rectangular.
Construction of the tube is the same as the construction chain hawse pipe made of steel plate (steel plate). Lower decline of the chain pipe section facing the tub fitted chain or attached half round iron. The upper waylay of this chain tube placed directly a propos the chain holes.
Some provisions of the chain locker:
Generally inside is lined in the in the future wood to prevent a mumble in the region of anchorage.
At the bottom of the chain tub perforated plate made for a habit out dirt / mud carried by the chain, and underneath there is a crate of mud that can easily be cleaned.
Provided Ranai decrease telecaster fastener tool that does not disappear behind anchoring. binding telecaster chain ends normally use "D" shackle hermetic sufficient and bo strength not less than 15% bebanputus darirantai presenter.
There should be a wall of loathing surrounded by the chain box to the left and right, left and right chain sehinggan not twisted and not acquire into shackle in the anchorage.
Machinery Anchor / Windlass
Anchor robot is a robot broadcaster mounted crane vessel for the seek of lifting and extend through the broadcaster and telecaster chain telecaster tube (hawse pipe).
The vessel shall have a special power birds (special generator) to steer the robot broadcaster (must be divided gone additional electrical installations) are above the driving force through the worm shaft (worm gear) will desire the main shaft of the robot telecaster, in prettify to the presenter engine fitted to the clutch system handy and motivate the driving force in force gone the main shaft.
Anchor robot should be placed upon the bow of the ship digeladak slant appropriately as to assist the operation of the narrowing and raising the anchor. In the engine mounting anchor upon the ship's deck, the deck slab creation areas should be strengthened as well as the robot anchor plate thickening as ably as a hermetically sealed opening construction.
At the era of scrutiny, anchor robot that has two drums should be skillful to lift the anchor chain along the 55 m derived simultaneously from the depths of the sea is not less than 6 minutes. To anchor a surgically remove robot along in the middle of the left and right anchor machines should each be swift to raise the anchor chain derived along the 82.5 m from the sea severity of not less than 9 minutes. This is a classification of the provisions of regulatory bodies.
Parts of the crane anchor is comprised of:
- Engine / motor is driven by a diesel / eclectic,
- Spil / wildcat is a roll / thromol that may implicate the anchor chain at the time passed,
- Clutch or ement that can official pardon or spil connecting the machine,
- The band brake to control spil gone not associated to the machine.
- Gears, connected following the shaft,
- Drum / gypsies, to abet tros vessel mounted upon the ends of the main shaft.
