Recommendations on the Hazard Identification of Fuel Changeover Processes

1 April 2013

This paper provides guidelines to oil tanker operators and other interested parties on the potential consequences of fuel switching between residual and distillate fuels where ships’ installations have typically been designed and manufactured to be used with residual fuels (HFO). INTERTANKO and OCIMF have developed this guidance with the aim of providing a simple check list of items which should be part of a Risk Assessment and a Hazard Identification (HAZID) assessment, for main engines, auxiliary engines and boiler systems in oil tankers covering the switching to, and long term operation on, low sulphur marine distillate fuel. It is recommended that such assessments are conducted in cooperation with classification societies, equipment manufacturers/installers and/or other experienced entities. The differences between the composition and physical properties of low sulphur marine distillate fuel and residual fuels (HFO) result in significant differences with regard to the safe operation of installed systems which should be addressed by specific operational instructions and procedures. Operators will need to undertake a risk assessment of the fuel switching process and, based on the results, consider the initial design or the need for modification to existing equipment, as well as updating instructions and providing associated training to the crew.

Recommendations on the Proactive Use of Voyage Data Recorder Information

1 October 2012

This paper highlights how the proactive analysis of Voyage Data Recorder information, on a regular basis, can provide an important tool for use in accident prevention and the reinforcement of a positive operational safety culture. The paper also depicts the analysis of tanker incidents during the period 1978 to 2011 which indicates that navigational incidents involving collisions, contacts or groundings have consistently accounted for around half of all incidents and how there is a potential to learn lessons from other industries, particularly aviation, by improving the analysis and assessment of available data.

Guidelines on Capabilities of Emergency Response Services

1 March 2013

Emergency Response Services (ERS) are rarely used, and as such may not attract appropriate priority of emphasis in vessel management. Merely having a service agreement in place does not ensure that, when needed, the quality of service provided meets the need. Recognising the potential hazards associated with the lack of consistency in the provision and utilisation of ERS, the OCIMF Marine Technical Sub-committee was tasked to form a Working Group to review current systems and practices in the industry, and to make any necessary recommendations for improvement. The objective of these Guidelines is to clarify and recommend the minimum scope of ERS provision, and to give advice on suggested minimum requirements of competency and capability of ERS service providers.

Marine Breakaway Couplings Information Paper

4 November 2008

Offshore marine terminals providing bulk liquid transfer facilities to tankers through floating and sub-sea flexible hose strings may be at risk of tanker breakout and surge pressures within the hose strings. Tanker breakouts may be as a result of parting of mooring hawsers due to excessive environmental forces and surge pressures may be experienced due to operational errors, such as the incorrect operation of transfer valves. Where no protective device has been installed, such incidents have resulted in the rupture of hoses or damage to Single Point Mooring systems (SPMs) and tanker pipework and fittings, with consequent pollution of the environment.

Guide For Implementation Of Sulphur Oxide Exhaust Gas Cleaning Systems

4 August 2016

The use of Exhaust Gas Cleaning Systems (EGCS) in the maritime industry is relatively new and there is a general lack of technical understanding and operational experience. MARPOL Annex VI sulphur oxide (SOx) compliance can only be achieved through the use of either low sulphur fuels or an EGCS. Due to the high cost of low sulphur fuels, there is an interest in continuing to use high sulphur fuels which would require the use of an EGCS. This information paper provides practical guidance for the selection, installation and use of SOx EGCS.

Inert Gas Systems The Use Of Inert Gas For The Carriage Of Flammable Oil Cargoes

13 March 2017

Hydrocarbon gas normally carried in petroleum tankers cannot burn in an atmosphere containing less than approximately 11% oxygen by volume. Accordingly, one way to provide protection against fires or explosions in the vapour space of cargo tanks is to keep the oxygen level below that figure. This is usually achieved by using a fixed piping arrangement to blow inert gas into each cargo tank in order to reduce the oxygen content and render the tank atmosphere non-flammable

A Guide to Best Practice for Navigational Assessments and Audits

10 October 2018

Navigational assessments and audits help vessel owners, operators and Masters to identify areas for improvement and increase safety. They also assure companies that high standards of navigation and watchkeeping are being maintained. While a wide range of navigational assessments are used in the industry, there is no common standard, and a lack of available guidance means that audits and assessments can vary in quality. This information paper gives guidance on how to conduct a good navigational assessment, including: • How assessments should be designed. • Why assessments are carried out. • Who should carry out assessments. • How an assessor should conduct assessments. • How the results can be used to identify trends and training requirements. The paper also features a full template that companies can use as a guide when developing their own navigational assessments.
