Each topic and area of interest provides access to more detailed documentation that is freely downloadable.
This includes our 17 Technical Information Papers which are fully illustrated with photos and diagrams and are available in several languages.
What happens to oil in the marine environment over time when spilled at sea? How do different factors such as volume and physical and chemical properties affect the fate of oil spills?
How does oil impact seabirds, plankton, sea mammals and the shoreline?
Which industries might suffer temporary economic losses and loss of market confidence?
What are the specific chemical response strategies for responding to a Hazardous and Noxious Substance spill, and what are the potential effects on human and marine life?
What information is needed for an effective oil spill contingency plan? How can aerial observation and protective strategies assist with response operations?
What techniques are available for cleaning up oil at sea and on the shoreline?
What planning and waste management systems need to be put in place to reduce the volume of oily waste for treatment or disposal?
What legal arrangements and sources of compensation are available for a spill from a ship?

This paper examines trends in tanker oil spills worldwide over a 20 year period from 1992 to 2011 and analyses potential influences on spill volumes and frequencies for incidents in the spill size groups 7-700 tonnes and >700 tonnes. ITOPF’s attendance of incidents is also analysed to demonstrate trends in the complexity of oil spill response.
While the hazards and consequences of oil spills are well known, little information exists for chemical spills. Words such as ‘carcinogenic’, ‘mutagenic’, and ‘neurotoxic’, which appear on shipping documents, are readily misinterpreted and extrapolated to worst-case scenarios causing public apprehension and mistrust. This paper attempts to answer the question ‘Are HNS Spills More Dangerous Than Oil Spills?
The question as to whether oil tankers should carry oil spill response equipment onboard has been the subject of debate for many years. The idea received considerable attention in the previous decade during the preparation of regulations by the United States Coast Guard as a result of the US Oil Pollution Act of 1990 (OPA'90).
At the outset of a major oil spill, it is hard to imagine how shorelines inundated with the thick black pollutant will ever be cleaned or that they will ever return to their original condition. Two facts are known as a result of these unfortunate experiences: first, these shorelines are eventually cleaned and second, that nature plays a very large part in that cleaning process.
The paper begins by reviewing the dramatic reduction in the incidence of major tanker spills since the beginning of the 1980s. The paper then focuses on the factors that determine the seriousness of marine oil spills and the fundamental technical difficulties of combating them at-sea, in coastal waters and on shorelines.
Based on ITOPF's extensive experience of spill clean-up around the world and quantitative data from recent spills in the UK, France, Turkey and Argentina, the paper will examine the wide range of technical, organisational, logistic and financial problems facing those responsible for managing shoreline clean-up operations.
This review of the practical lessons which can be learnt from past events is intended to provide an informed basis for the selection of more effective response techniques and equipment, and for the development of improved spill response management and contingency planning
The concept of persistence in relation to oil spills probably originated after the Torrey Canyon incident in 1967. This is when discussions first arose regarding various new measures to protect the marine environment and to manage marine oil spills, particularly in relation to liability and compensation.
Within the wider debate on the effectiveness of at-sea recovery, this paper investigates whether the particular characteristics of heavy oils warrant special consideration when planning and responding to spills of these oils. The paper reviews arguments for and against greater at-sea recovery efforts than would be justified with other, lighter oils.
