Maritime Conventions and Codes on Amazon

wp-1481562626266.jpgThroughout the recent posts on this blog have been references to various International Maritime Conventions and Codes. Now that all the key certificates have been covered, it is probably a good time to provide a quick reference to where to purchase the source publications.

Where to find the publications on Amazon

When I started building this post my intention was to give links to each book. Unfortunately, I was soon thwarted by the high range in prices being offered on line. In order to avoid providing links towards overpriced I have instead given some search links that will allow a quick check of what is currently being offered on-line.

Before buying through Amazon then it is recommended to check the suppliers and prices IMOfrom the IMO, at their publication page.

The High Speed Craft Safety Certificate


This journey through ship certification is now exploring some of the more specialized certificates, that is that required by High speed Craft.

Two High Speed craft Codes

  • The International Code of safety for High speed Craft 1994
  • The International Code of safety for High speed Craft 2000

The 2000 Code applies to high speed craft of which the keels were laid or which are at a similar stage of construction on or after 1 July 2002.

The High Speed Craft Safety Certificate

Why is the HSC safety certificate required?

It is required by the International Code of safety for High-speed craft 2000 ( the HSC CertHSCUKcode)

What does it certify?        

That the craft has been surveyed in accordance with the HSC code and in all respects the craft complies with the relevant provisions of the Code.

That the life‐saving appliances are provided for a stated number of persons

What is a high speed craft?

High-speed craft is a craft capable of a maximum speed, in metres per second (m/s), equal to or exceeding a value obtained from the formula

Cert HSC formula

Where Delta is the volume of displacement corresponding to the design waterline (m3),excluding craft the hull of which is supported completely clear above the water surface in non-displacement mode by aerodynamic forces generated by ground effect.

What vessels must comply with the High Speed craft code?

High speed craft that:

  • Are engaged in international voyages

    it is interfacing with
  • There is an agreement on a Declaration of Security between Contracting Governments covering certain international voyages or specific ships on those
  • There has been a security threat or a security incident involving the ship or
    involving the port facility
  • The ship is at a port which is not required to have and implement an approved port
    facility security plan
  • The ship is conducting ship to ship activities with another ship not required to have and implement an approved ship security plan

Who completes the declaration of Security?

  • The master or the ship security officer on behalf of the ship(s); and, if appropriate,
  • The port facility security officer or, if the Contracting Government determines
    otherwise, by any other body responsible for shore-side security, on behalf of the
    port facility

What is contained on the Declaration of Security between a ship and a port facility?

Navsregs>Ship Certification>EIAPP

The EIAPP- Certifying the engines

The last two posts in this series covered certificates that are concerned with reducing air pollution from a ship, this post delves deeper into the subject by considering reducing pollution from individual diesel engines.

What is the EIAPP Certificate?

It is the Engine International air pollution prevention Certificate. It is a certificate issued for a marine diesel engine. The EIAPP Certificate shall accompany the engine throughout its life and shall be available on board the ship at all times.

Why is an EIAPP required?

It is required by Technical Code on Control of Emission of Nitrogen Oxides from Marine Diesel Engines made mandatory by Annex VI of MARPOL.

Which engines require an EIAPP?

  • Eac
  • h marine diesel engine with a power output of more than 130 kW installed on a ship
  • Each marine diesel engine with a power output of more than 130 kW which undergoes a major conversion on or after 1 January 2000 except when demonstrated to the satisfaction of the Administration that such engine is an identical replacement to the engine which it is replacing.

The following engines do not require an EIAPP

  • A diesel engine intended to be used solely for emergencies, or solely to power any device or equipment intended to be used solely for emergencies on the ship on which it is installed
  • A marine diesel engine installed in lifeboats intended to be used solely for emergencies
  • A marine diesel engine installed on a ship solely engaged in voyages within waters subject to the sovereignty or jurisdiction of the State the flag of which the ship is entitled to fly, provided that such engine is subject to an alternative NOx control measure established by the Administration

What does the EIAPP certify?

That a marine diesel engine has been surveyed for pre-certification in accordance with the requirements of the revised Technical Code on Control of Emission of Nitrogen Oxides.

That the pre-certification survey shows that the engine, its components, adjustable features, and Technical File, prior to the engine’s installation and/or service on board a ship, fully comply with the applicable regulation 13 of Annex VI of MARPOL.

How long is an EIAPP valid?

For the life of the engine subject to surveys in accordance with regulation 5 of Annex VI of the Convention.

What information is contained on the EIAPP Certificate?

The certificate contains a table with the following headings

  • Engine
  • Manufacturer
  • Model number
  • Serial number
  • Test cycle(s)
  • Rated power (kW) and speed (RPM)
  • Engine approval number

What document must be attached to the EIAPP?

The Supplement to engine international air pollution prevention certificate.

The Supplement to engine international air pollution prevention certificate 

This documents full name is the ‘Record of construction, technical file and means of verification supplement to the engine international air pollution prevention certificate (EIAPP Certificate)’.

The Record and its attachments shall be permanently attached to the EIAPP Certificate.

What Sections does the record contain?

  • Particulars of the technical file
  • Particulars of the engine
  • Specifications for the on-board NOx verification procedures for the engine parameter survey

What Particulars of the technical file are recorded?

  • Technical File identification/approval number
  • Technical File approval date

What Particulars of the engine are recorded?

  • Name and address of manufacturer
  • Place of engine build
  • Date of engine build
  • Place of pre-certification survey
  • Date of pre-certification survey
  • Engine type and model number
  • Engine serial number
  • If applicable, engine group details.
  • Approval reference
  • Rated power (kW) and rated speed (rpm) values or ranges
  • Test cycle(s)
  • Parent Engine(s) test fuel oil specification
  • Applicable NOx emission limit (g/kWh
  • Parent Engine(s) emission value (g/kWh)

What Specifications for the on-board NOx verification procedures for the engine parameter survey are contained?

  • Engine Parameter Check method:
    • Identification/approval number
    • Approval date
  • Direct Measurement and Monitoring method:
    • Identification/approval number
    • Approval date

What additional document must always accompany an engine?

The Technical File as required by chapter 2 of the NO x Technical Code, must always accompany an engine throughout its life and always be available on board a ship. It forms an integral part of the EAIPP certification.
