Overview:

In the port of Sydney the ship can use its own crew to handle lines during un-berthing and berthing operations at the wharf. Therefore crew must be capable of carrying out these duties in a competent and safe manner.

Note;

A ship anchors when the ship’s anchor is used.

A ship moors when secured to a buoy.

A ship berths when made fast alongside a wharf.

Anchoring and mooring will be covered in later modules.

Assessment:

Oral and practical examination by a Watchleader, who will, when satisfied, sign off the relevant parts in the crew member’s ‘Diary of Service and Experience Log’ book.

Outcome:

Crew to competently and safely carry out the tasks covered in the module.

Berthing Hawsers

Diagram shows how berthing hawsers are used to secure a ship alongside a wharf or a jetty. In this case Port Side to.

Springs

The hawser marked 3 is known as the fore spring and the hawser marked 4 as the after spring. When a ship is secured alongside, the springs prevent her from surging ahead or astern at her berth, and together they assist the breast ropes marked 2 and 5 to keep her close alongside.

Head and stern Ropes

The hawsers marked 1 & 6 are known as the head rope and the stern rope. They assist the springs in preventing the ship from surging, and they are also used to adjust the position of the ship along the wharf or jetty, especially when she is going alongside.

Breast ropes

The ship has two breast ropes, marked 2 & 5, which are known respectively as the fore and after breast ropes. They are used to breast the ship bodily towards the jetty when coming alongside, and when belayed they limit her distance from the jetty.

Berthing

Aboard

When a ship is going alongside, the berthing hawsers required for working the ship to her berth will usually be a head rope, a stern rope, one forward and one after spring, and perhaps two breast ropes. The order in which they will go out depends upon the circumstances and will be called by the Officer of the Watch.

Clear the area around the bitts and install safety barriers.

Each berthing hawser required for work­ing the ship should be ready and faked down for running, with its bollard eye led out through the correct fairlead and stopped outboard to the top guardrail, where it will be ready for a heaving line to be bent on by the time the ship is within heaving distance of the jetty.

If the capstan is to be used, it will prob­ably be for breasting the ship in with the breast ropes, or for adjusting her distance along the jetty with the head and stern ropes.

When a ship is secured alongside where there is a large tide range, particular attention must always be paid to her berthing hawsers as she rises and falls with the tide, and, whenever possible, the hawsers should be so belayed that each can be tended without disturbing another.

Make sure the electrical cable is supported i.e. not carry its own weight or become another berthing line.

A berthing hawser may be doubled up by a second hawser between ship and shore; such hawsers are usually singled up well before the ship is due to slip so as not to delay the final stage of slipping. Doubling up may be used if adverse weather conditions are expected.

A berthing hawser may also be rove doubled when there is no shore party to cast it off when the ship slips, both ends of the hawser are made fast inboard.

On the wharf

Berthing party members stand by to receive heaving lines which will be used to haul the attached hawser ashore. Place the hawser eye on the bollard required.

Securing A Line To A Hawser

Securing a heaving line to an eye in a hawser.

A round turn around the hawser, away from the eye, prevents the heaving line from slipping to the end of the eye thus binding on the bollard and hindering removal of heaving line when load goes on the hawser. E.g. Springs, head line etc.

image1

Securing a heaving line to a bight in a hawser.

Loop in heaving line allows the hawser to slide through to adjust length.

e.g. Breast lines.

image2

Throwing A Heaving Line

A heaving line is a light flexible line, weighted at one end that can be thrown. It is used as a messenger to pass a hawser from ship to shore, or vice versa.

image3

To prepare a line for throwing;

  1. Make the standing end fast.
  2. The line should be coiled carefully in the left hand. The last third of the coils can be of smaller diameter. Make sure the head will not pass back through the coils during the throw.
  3. One third of the line (smaller coils) is taken in the right or throwing hand. Line must be allowed to run free from the left hand.

There is more than one method of heaving a line and most good throwers have their own variations.

To Catch A Turn Round Twin Bollards Or Bitt

Diagram shows how to catch turns with line under strain round twin bollard. Note that the lead is first to the bollard furthest from the source of strain, and from outboard to inboard. Belaying turns of a hawser leading forward are taken right-handed on the starboard side of a ship, and left-handed on the port side.

Also refer to pictures in Module 5, pages 9 &10.

To handle a hawser, which is alternatively slack and under strain.

If space permits, it is best to keep one turn on the bollard and man the hawser before all when hauling in the slack. As the slack comes in, one man (or two with a very large hawser) can fleet it round the bollards, and at the same time be ready to back it up and take more turns when the strain comes on.

Backing Up

When a seaman finds that the strain on a hawser is becoming more than he can hold he instinctively takes a turn round the nearest bollard, cleat or other fixture, and then backs up the additional grip thus obtained with his own weight. If he expects a still heavier strain he takes as many additional turns round the fixture as are required to take the strain.

Un-berthing

On board

Clear the area around the bitts and install safety barriers around the area.

Prepare lines.

When a ship leaves a jetty the number of berthing hawsers required will depend upon the circumstances, but normally the head and stern ropes and one forward and one after spring should suffice. The head and stern ropes may have to be brought to the capstans and the springs may have to be surged.

The order in which the hawsers are to be taken aboard will be called by the Officer of the Watch.

Any doubled lines will be hauled on board on the order Single up.

Stand clear of any lines that may come under load.

Haul hawsers onboard smartly on command. Coil and stow securely.

On the wharf

Berthing party will cast off hawsers as instructed by the Officer of the Watch. Walk the hawsers along the wharf and avoid casting them into the water.

Coiling Down A Hawser Or Large Diameter Line

Coiling down in the manner shown will enable to hawser to be run out quickly without upsetting the whole coil.

image4

Step 1; Coil clockwise from outside in. Once in the centre lead the hawser to the outside and repeat.

image5

Step 2; Continue with layers. Stagger the leads to the outside on each layer.

Waring The Ship

If it is necessary to reposition the ship while alongside without using the engines or tug it can be carried by using the berthing hawsers.

When a shix is being w`rped by her berthing hawsurs each hqwser shoult be tended, ald the iands tending them should be rrepared to back up, sur’e, take do÷n the slack, bring to the capstan, or$bela} them, as$sequired. Clore attention to!berthin’ instrugtions a~d smartjesS io handling hawsers hs essdntial.

Tug

A tug may be used when slipping and berthing. Make sure the ship’s rig will not foul the tug’s supurstructure.-Crew on board will receive the tug’s towing line through t|he appropriate fairlead.

Use a boat hook to take the line* Pass the eye over the appropriate bitts.

Crew are to stand well clear of the line.

Line is slipped after manoeuvre has been completed.

To secure a berthing line to a single post or bitt.

This is an`excellent m%thod of securing a line as it can be readily applied and released under control. `

To Catch Turn On A Single Bollard Or Bitt

When a rope is under strain, catching a turn round a single bollard is difficuht unless done corvectly.

image7

Careful attention should be paid to the position of the hands and fingers to prevent them being nipped, especially if the hawser should render.

Two Or Bollard Or More Berthing Hawsers Over A Single Bitt (dipping An Eye)

When two or more berthing hawsers have to be secured to the same bollard the eye of the second hawser must be passed up through the eye of the first before it is placed over the bollard, the eye of a third hawser must be passed up through the eyes of the first two, then over the bollard. The hawsers can then be cast off the bollard in any order.

Berthing Party Check List

Berthing party is made up a Leader and 3 crew.

The party attends to the tasks below.(Once the ship is safely away and the wharf area is secure, they return to the ship via the tug. The reverse occurs for arrival.

Automatic inflating life jackets are worn by all members of the party at all times. Refer to Module 11, Page 8.

Berthing party members are also the Ship’s Stretcher Party.

Slipping

  1. Remove locked security chain from bollards.
  2. Invert wheels on gangway.
  3. Rig line for removing shore power lead.
  4. Ensure shore power cable is removed before slipping lines.
  5. Disconnect water/ waste-water hoses.
  6. Single up lines as ordered by Watchleader/Officer of the watch.
  7. Remove gangway safety net and stow onboard.
  8. Remove gangway safely and store safely clear of the public way.
  9. Let go lines as requested by OOW.

Berthing

  1. Bollards clear, in good condition and ready to receive lines.
  2. Place the ship’s lines on bollards, dipping the eye when appropriate.
  3. Have gangway ready to secure to the ship
  4. Secure the ship’s safety net to the shore.
  5. Invert wheels on gangway.
  6. Lock berthing lines to bollards.
  7. Have lines ready to bring power cable/ water hose ashore.
  8. Ensure power cable is not taking any ship load.(i.e. not acting as a berthing line).
  9. Return equipment (heaving lines, spanners, chain key) to the ship.
  10. Stow life jackets.

Safety

Refer to Module 5 for Safe Line Handling.

  1. Life jackets are to be worn by berthing party, at all Times.
  2. DO NOT stand in line or close to hawsers that are under or about to come under high loads. If it parts it may come straight back at you.
  3. When removing or placing hawsers on the bollards or bits keep hands and fingers clear of dangers areas e.g. Where they may be placed between ” the hawser and the bollard and squashed.
  4. Synthetic hawsers under high load may part without warning. A danger

Sign is a marked decrease in hawsers diameter. Move well clear

Mooring

In harbours and confined waterways where there is no room for a vessel to drop anchor or berth at a wharf, mooring buoys are sometimes available.

The ship is brought up to the Buoy, preferably up wind or up tide whichever is the stronger, and temporarily hauled to the buoy with the Picking-up rope. In need a tug may be used to aid the ship.

The Mooring Bridle, with one end secured to the ship, the other end rove through the ring at the buoy and secured back on board. The Pick-up rope is then slipped from the buoy and recovered on board.

The weight of the ship is taken on the Mooring Bridle. One end is slipped when leaving the buoy.

In conditions of wind and tide are satisfactory the Pick-up rope may be dispensed with and the Mooring Bridle passed down directly to the buoy to be rove directly through the buoy eye and passed back to the ship by heaving line.

If a ship is to remain secured to a mooring buoy for an extended time it is practice to cut the anchor, break the cable at the first half shackle (of cable) and use a buoy shackle (Hartford shackle) to secure the ship to the buoy by the ship’s anchor cable.

The Ship’s sea boat or a tug is used to carry the lines between the ship and the buoy. The crew carrying out this task is called the “Buoy Jumper”.

A typical mooring set-up.

Steps

Securing to the buoy;

  1. Lines are set out on deck as in previous sketch.
  2. The sea boat takes a pickup rope to the buoy. If required the ship’s windlass is used to haul the ship up to the buoy.
  3. Attach a heaving line to the bridle, Pass the heaving line through the eye of the buoy and back to the ship.
  4. Use the heaving line to haul the Moring Bridle through the eye and back on board and secure.
  1. Recover the pickup rope*

Departure;

Release one end of the Moring Bridle and haul through the buoy eye and back to the ship.
