Authorised independent examination, investigation, and inspection, measuring or testing of ship structure, machinery and equipment, done and supervised by Surveyors appointed by regulatory or commercial organisations.

Classification Societies:
They are third party independent bodies e.g. ABS (American Bureau of Shipping), BV (Bureau Veritas), LR (Lloyd’s Register), ClassNK (Nippon Kaiji Kyokai), DNV (Det Norske Veritas), GL (Germanischer Lloyd).

Their functions:
1. To ensure that ship is soundly constructed and the standard of construction is maintained.
2. Carried out Statutory Survey on behalf of the Administration regarding the ship safety and prevention of pollution of marine environment.

Classed ship:

  •  A ship, which is built in standard and maintained under rules and regulations of Classification
  • For a ship to be entitled to a class, Classification Society issues a Classification Certificate after carrying out Classification Surveys.
  • Classification Certificate confirms that the ship has both structural and mechanical fitness for their intended services.

Maintaining the class:
To maintain a ship in the class:
–  The owner must carry out regular surveys of hull, machinery and equipment.
–  Carry out repairs necessary from time to time, under the supervision of Class Surveyors.

Statutory Survey:
–  Carried out by Administration regarding the safety of the ship, sea worthiness and pollution, in accordance with national and international rules.
–  Issued a certificate, this is essential to the ship’s ability to trade.
–  If Statutory Survey is not certified, the ship can be detained.

Statutory Surveys are:

  • International tonnage survey
  • International load line survey 5 years interval
  • Cargo ship safety construction survey 5 years –
  • Cargo ship safety equipment survey 2 years –
  • Cargo ship safety radio survey 1 year –
  • Marpol IOPP & IAPP survey 5 years –

Classification Survey:

  • Carried out by Classification Surveyor, to ensure that the ship has both structural and mechanical fitness, for intended voyage, in accordance with the class requirements.
  • A classification survey is a visual examination that normally consists of:
    –  an overall examination of the items identified in the Rules for survey;
    –  detailed checks of selected parts, on a sampling basis;
    –  witnessing tests, measurements and trials where applicable.

Difference bet: Statutory Survey and Classification Survey:

  •  Statutory surveys are not assessing or measuring something for a client.
  • Statutory survey will inspect something against a set standard or law.
  • On completion of this survey, the ship is issued with a certificate, which is essential to the ship’s ability to trade.
  • Class cannot go to the ship unless requested by the owner, or unless the ship is detained by the Port State Control.

Why Classification Societies sometimes issue the Statutory Certificate?

  • Sometimes Administration delegates the authority, to the Classification Society to inspect and issue Certificates, on their behalf, regarding statutory requirements.

Port State Control:

1. Port State Inspection is a particular form of Statutory Survey.
2. Intention of Survey is to check that, ships flying the Flags of States comply with the Requirements of the Conventions.
3. When these ships are in Ports of States, Port State Authority has control over the ships in port, and has rights to inspect the followings, in order to avoid Substandard Ships:
– Safety Equipment.
– IOPP & IAPP Certificate.
– Oil Record Book.
– Sewage Treatment Plant.
– MARPOL Equipment.

For PSC purposes, Port Authorities will apply in general, the following Instruments.
ILL 66, SOLAS 74, MARPOL 73/78, STCW 78, COLARG 72 and ILO 76.

4. A Surveyor representing the Authority of the Government carries out the Port State Inspection.

Preparation for Port State Control Inspection: [As a CE]

  •  IOPP, IAPP, IEE Certificates for MARPOL
  • Load Line Certificate
  • SOLAS Certificates
  • STCW Certificates, kept ready.
  • Safety Equipment prepared for testing and inspection.
  • MARPOL Equipment prepared for testing and inspection, such as:
    – OWS operation and alarm test.
    – Incinerator tested and kept ready for demonstration, and alarm test.
    – Sewage Treatment Plant, in good order, and dose chemicals.
    – Tank top near OWS and Bilge Pumping Station kept clean.
    – Bilge overboard discharge valve, tightly closed and kept under lock and key.
    – Update and attach ORB, with photocopies of MARPOL Certificates, original Oil Disposal Receipts, and Dirty Oil and Sludge Piping Diagram.

Flag State control:

1. Flag State or Administration has responsibilities that the ships built to their flag, comply with the Requirements of the Conventions, in construction and upkeep afterwards.
2. Government body carried out Surveys and issued Certificates relating to safety of the ship, sea worthiness and pollution.
3. Flag State Control is limited to ensure that valid Certificates are onboard:

  1. Passenger ship safety certificate Validity 1 year.
  2. Cargo ship safety construction certificate 5 years
  3. Cargo ship safety equipment certificate 2 years
  4. Cargo ship safety radio certificate 1 year

  • For PSC purposes, Port Authorities will apply in general the following Instruments.

1. International Convention of Load Line. ILL 66
2. International Convention for Safety of Life at Sea. SOLAS 1974.
3. International Convention for the Prevention of Pollution from Ships.
MARPOL 1973/78

  • Validity is until next survey due.

Certificate of Seaworthiness:

  • To enable to proceed to the next port, the Surveyor other than Class Surveyor issues it.
  • If the Classification Surveyor does not carry out the survey, the requisite certificate that is issued will be one of seaworthiness.
  • This Certificate enables the vessel to proceed to her next port, where a further survey by the Classification Surveyor will be conducted, so that Interim Certificate of Class can be issued.

1. The fitness of the vessel in all respects for carrying cargo and crew in safe condition.
2. Important items concerned are stability, strength, freeboard, machinery and design, and they must be entirely satisfactory.

Franchise Clauses:

  • These state certain portion of insured value, for which Insurers are not liable to pay.
  • There are two kinds of franchises:
    [These state the percentage of the claim, which the Assured must bear.]


1. If amount of loss does not exceed the franchise amount the Insurers (Underwriters) are not liable to pay at all.
2. But if the amount of loss exceeds the franchise amount Insurers are liable to pay that portion which exceeds the franchise amount.
[Only claims in excess of certain percentages are paid, i.e. the Assured pays the first so much
percentage of any claim.]


1. If amount of loss does not exceed the franchise amount the Insurers (Underwriters) are not liable to pay at all.
2. But if the amount of loss exceeds the franchise amount Insurers are liable to pay the whole amount.
[The Underwriter pays the whole claim if it exceeds the stipulated percentage.]

1200°C, [Melting point of CI].
2. Welding rod: pure CI with high silicon content.
3. Part to be welded is preheated to 600 ~ 700°C, to avoid excessive stresses.
4. During welding, gas bubbles are developed in molten weld pool. By striking the pool in circular motion with welding rod, these bubbles can be removed.
5. It is necessary to use welding flux.

Arc Welding:

1. Electrode: pure nickel (or) nickel iron.
2. Weld metal, deposited in short thin beads with small electrode and low amperage, to avoid local heat built up and expansion, around weld point.
3. Casting is allowed to cool, between each run.

Gas Welding:

1. Used for thickness of plate up to 3/16″.
2. Slightly excess acetylene is used, due to lower melting point, 660°C.

5. Avoid inhalation of smoke, produced during welding.

Arc Welding:

1. Thickness of plate ¼ ” or more.
2. Electrode: 95% Aluminium, 5% Silicon: with 20°of vertical.
3. Keep arc as short as possible, low amperage and movement is in straight line.
4. Welding speed is 3 times faster than mild steel.
5. Thick plate should be preheated for smooth weld.
6. Traces of flux, removed with hot water after gas or arc welding, otherwise flux corrosion will occur.

Inert gas welding:

1. Welds are superior in strength and pressure tightness.
2. No flux is required, so no risk of corrosion.
3. Very high speed is possible with welding machine.
4. Gas metallic arc welding GMAW or MIG is easier to use, particularly where position welding is needed, vertical, horizontal or overhead.
5. For plate thickness of ¼ ” MIG is more economical and practical.
