What is a nautical chart according to SOLAS?

Reg 2 of SOLAS V states that it is map or a specially compiled database from which such a map is derived. It also has to be issued officially by or on the authority of a Government, authorized Hydrographic Office or other relevant government institution and is designed to meet the requirements of marine navigation.

UK guidance states that a chart must be of such a scale and contain sufficient detail as clearly to show:

  • All navigational marks which may be used by a ship when navigating the waters which are covered by the chart;
  • All known dangers affecting those waters;
  • All information concerning any ships’ routeing and ship reporting measures applicable to those waters.

A Handy Guide to SOLAS V Regulation 17 – Electromagnetic Compatibility

Polarcus Alima's bridge

After that brief pause to look at changes to MARPOL this blog now returns to exploring the regulations of SOLAS Chapter V.

Click here to read Regulation 17 on the UK MCA website>

What vessels must comply with Regulation 17?

Ships constructed on or after 1 July 2002

What does this regulation require regarding equipment testing of bridge equipment?

That all electrical and electronic equipment on the bridge or in the vicinity of the bridge is tested for electromagnetic compatibility (EMC).

What resolution gives the requirements for Electromagnetic compatibility with navigational equipment?

A.813(19)

Click here to view the resolution>

What should the installation of electrical and electronic equipment avoid with regards to bridge navigation equipment?

Electromagnetic interference affecting the proper function of navigational systems and equipment. Portable electrical and electronic equipment shall not be operated on the bridge if it may affect the proper function of navigational systems and equipment.

What must masters ensure regarding portable electronic equipment being used on a ship’s bridge?

That no portable electrical or electronic equipment that might cause interference is used on or near the bridge. This includes not only ship’s equipment but also personal items such as  portable radios, hi-fi equipment and lap top computers. Non-transmitting equipment displaying the European “CE” mark will probably not cause interference.

Mobile phones, while not likely to cause electromagnetic interference, prove to be an increasing distraction to safe navigation. MGN (M&F) 299 – Interference with Safe Navigation through inappropriate use of Mobile Phones is to be complied with.

The maintenance of navigation equipment

Navsregs>SOLAS>SOLAS V>Maintenance of Navigational Equipment

Radars , radios and lights on ship's gantry mastSOLAS V Regulation 16-Maintenance of equipment.

On the Navregs  blog writing the front the exploration of SOLAS V continues . This time the focus is on maintenance.

What is the requirements for the maintenance of navigational equipment?

That adequate arrangements are in place to ensure that the performance of the equipment required by SOLAS Chapter V is maintained.

Note This will include ensuring that proper manuals enabling on-board maintenance are available and that that companies have ensured a comprehensive back-up service, including provision of both spares and maintenance engineers by manufacturers or their agents.

Can a vessel sail with defective navigational equipment?

Yes, where repair facilities are not readily available, provided suitable arrangements are made by the master to take the inoperative equipment or unavailable information into account in planning and executing a safe voyage to a port where repairs can take place. In such cases the vessel must obtain approval from their flag state. Approval to sail will not apply to cases when the defects are detected during a safety survey.

The decision to allow a vessel to sale with defective equipment  will depend on the equipment involved, the magnitude of the malfunction and it’s effect on the ship being able to complete the voyage safely.

Equipment manuals and IEC

IEC 60945, issued by the IEC states that equipment manuals must be:

  • Be written in English
  • Identify the category of the equipment or units to which they refer
  • in the case of equipment so designed that fault diagnosis and repair down to component level are practicable, provide full circuit diagrams, component layouts and a component parts list
  • In the case of equipment containing complex modules in which fault diagnosis and repair down to component level are not practicable, contain sufficient information to enable a defective complex module to be located, identified and replaced.

IEC is the international Electrotechnical Commission.

ISM and maintenance

ISM paragraph 5.10 contains the codes requirements for maintenance.

“5.10 Maintenance of the Ship and Equipment

5.10.1 The Company should establish procedures to ensure that the ship is maintained in conformity with the provisions of the relevant rules and regulations and with any additional requirements which may be established by the Company.

5.10.2 In meeting these requirements the Company should ensure that:
.1 inspections are held at appropriate intervals;
.2 any non-conformity is reported, with its possible cause, if known;
.3 appropriate corrective action is taken; and
.4 records of these activities are maintained”

The use of heading and track control- a quick guide

Navsregs>SOLAS>SOLAS V>Heading and Track Control
A cargo ship at sunrise off DawlishAnother SOLAS V Regulation, and another regulation on steering gear. This one covers what used to be called the  ‘Auto Pilot’, before technology gave us many variations to play with.

The importance of the steering gear in safety of navigation is reflected in the fact there are several regulations devoted to it within SOLAS V. So far this blog has covered these two-

And now, it will look at a third.

SOLAS V Regulation 24 – Use of heading and/or track control systems-a quick guide

When must it be possible to immediately establish manual control of a ship’s steering?

  • In areas of high traffic density
  • in conditions of restricted visibility
  • in all other hazardous navigational situations

 “(l) The term “restricted visibility” means any condition in which visibility is restricted by fog, mist, falling snow, heavy rainstorms, sandstorms or any other similar causes.” COLREGS Rule 3

What must the Officer of the watch have immediately available in  areas of high traffic density, in conditions of restricted visibility, and in all other hazardous navigational situations?

The services of a qualified helmsperson who shall be ready at all times to take over steering control.

How should the changeover from automatic to manual steering and vice versa shall be made?

By or under the supervision of a responsible officer.

When at sea should the manual steering be tested?

After prolonged use of heading and/or track control systems, and before entering areas where navigation demands special caution.

What International standard refers to Heading Control standards?

And so the wader through SOLAS V continues with its equipment related theme. This time its the steering gear, and in particular. the tests an Officer of the Watch must conduct.

Regulation 26-Steering gear- Testing and Drills

This Regulation within SOLAS V contains the requirements for the pre-sailing tests of steering gear tests.

Click here for the UK MCA guidance on Regulation 26>

When should the pre-departure testing of steering gear be conducted?

It should be tested within 12 hours before departure

What equipment should include within the steering gear testing procedure?

  • The main steering gear
  • The auxiliary steering gear
  • The remote steering gear control systems
  • The steering positions located on the navigation bridge
  • The emergency power supply
  • The rudder angle indicators in relation to the actual position of the rudder
  • The remote steering gear control system power failure alarms
  • The steering gear power unit failure alarms
  • The automatic isolating arrangements and other automatic equipment

What tests and checks should be included in the steering gear testing procedures?

  • The full movement of the rudder according to the required capabilities of the steering gear
  • A visual inspection for the steering gear and its connecting linkage
  • The operation of the means of communication between the navigation bridge and steering gear compartment

Movement-Visual-Communications

The flag state may waive the requirements to carry out the checks and tests for ships which regularly engage on short voyages. Such ships shall carry out these checks and tests at least once every week.

How often should the emergency steering gear be tested?

Emergency steering drills shall take place at least once every three months.

These drills shall include

  • Direct control within the steering gear compartment
  • The communications procedure with the navigation bridge
  • Where applicable, the operation of alternative power supplies

The date upon which the checks and tests are carried out and the date and details of emergency steering drills carried shall be recorded.

What should be displayed regarding the steering gear change over procedures?

A simple operating instructions with a block diagram showing the change-over procedures for remote steering gear control systems. This shall be permanently displayed on the navigation bridge and in the steering compartment.

Note: All ships’ officers concerned with the operation and/or maintenance of steering gear shall be familiar with the operation of the steering systems fitted on the ship and with the procedures for changing from one system to another.

Car ferry manouvering

In addition to the testing requirements, SOLAS V contains a short regulation requiring the use of more than one steering gear.

SOLAS V Regulation 25-Operation of Steering Gear

When should more than one steering gear be used?

In areas where navigation demands special caution,  when steering gear units are capable of simultaneous operation.

Click here for MCA guidance on Regulation 25>

A diversion beyond SOLAS V into the Construction section of the convention gives the performance standards required when testing the steering gear.

SOLAS II-1 Regulation 29-Steering Gear

How quick should a rudder turn?

At maximum ahead service speed the rudder must be capable of putting the rudder over:

From 35° on one side to 35° on the other side

and

From 35° on either side to 30° on the other side in not more than 28 seconds.

The auxiliary steering gear shall be of adequate strength and capable of steering the ship at navigable speed and be capable of putting the rudder over from 15° on one side to 15° on the other side in not more than 60 seconds at one half of the maximum ahead service speed or 7 knots, whichever is the greater.
