CoC Oral Exam Preparation (Part- 2) – Survey & Certification
Image Credit: Marinelink
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.
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).
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.
- 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.
– 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 –
- 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.

– 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:
- Passenger ship safety certificate Validity 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.
