1 The Influence of Regulations on the Safety Record of the Aframax Tankers S. Delautre, Bureau Veritas, France E. Eliopoulou, National Technical University of Athens, Greece N. Mikelis Intertanko, United Kingdom An analysis carried out as part of the POP&C project # on the incidents/accidents experienced by the Aframax fleet of (80,000 to 120,000 DWT tonnes) for the period 1978 to 2003 has shown that there is a definite and sharp decline on the frequencies of occurrence in all categories of accident considered in the project, i.e. collision, contact, grounding, nonaccidental structural failure, fire, and explosion. Statistics have shown that averaged frequency rates for all types of accidents for the period between 1978 and 1990 were reduced to about one third in the period and to about one eighth in the last 5 years period Many regulations and also some industry initiatives have come into force during these last 26 years. There is no doubt that some of these regulations and initiatives had a definite impact on the decline of the accidents rates. The regulations helped to harmonize the quality level of the shipping industry by making mandatory some equipment and procedures which often already existed in the best shipping companies and on-board their ships. The present study identifies the introduction of key regulations that may explain the declining trends of accident/incident rates. It should be noted that the focus of this study is aimed at regulations which prevent accidents/incidents taking place, and not at regulations intended to mitigate the consequences of accidents. It is also noted that the interpretation as to which accident categories are affected by each regulation is to some degree subjective. # The Pollution Prevention & Control (POP&C) project is financially supported by the European Commission under the FP6 Sustainable Surface Transport Programme. 1

2 REGULATIONS Date of entry into force Applicable Description Comments to * Collision Contact Grounding NASF Fire Explosion 1972 International regulations for the prevention of collisions at sea, COLREG 1977 All ships One of the most important innovations in the 1972 COLREGs was the recognition given to traffic separation schemes. Rule 10 gives guidance in determining safe speed, the risk of collision and the conduct of vessels operating in or near traffic separation schemes Existing ships Range of lights and colour specification Impact on the prevention of Collision Impact on the prevention of Collision due to the navigational lights and colour code Existing ships Navigation lights, positioning and sound signals Impact on the prevention of Collision due to the navigational lights and sound signals SOLAS 1980 New ships Special requirements for - fire safety provisions: inert gas systems - requirements for carrying of radar and collision avoidance aids Impact on the prevention of Collision and contact due to the navigational equipments. Impact on the prevention of fire & explosion due to the inert gas system Paris Memorandum of the understanding 1982 All ships entering ports of Regulations with respect to Port State Control in Europe and Canada The memorandum, although not introducing new regulations by itself, authorises and harmonises Port State Control within Europe * Note: New ships means new in relation to the enter into force date of the respective convention/amendments, while an existing ship means a ship constructed before that date. 2

The STCW code has been introduced and is mandatory for both countries that signed the convention and seafarers that enter countries which are party to the convention. * until 1 st of February 2002, Parties may continue to issue, recognise and endorse certificates which applied before that date in respect to seafarers who began training or seagoing service before 1 st August 1998 and Canada. Although the countries party to the ParisMOU already enforced PSC in one way or the other, the ParisMOU made the PSC more effective by combining each countries inspection reports. The STCW ensured that the level & quality of training of the mariners given by the national authorities was in accordance with the minimum standards prescribed by the regulation. The educational systems were examined by the IMO groups of experts who established a white list of all the countries which complied with the convention s standards. It is envisaged to perform this review every 5 years. Certainly the STCW had an impact on the shipping industry and on the decrease of the accidents rates. It ensured a universal level & quality of training of the seafarers. The STCW had an impact on the decrease of the collision, contact and grounding accidents Collision bulkhead, bilge pumping arrangement, Provisions for halogenated hydrocarbon extinguishing systems, As said before, most of the navigational equipments were already on-board most of the ships. The regulations made mandatory these equipments (harmonization) or gave additional requirements such as the duplication of some of 3

The OPA90 liability provisions may have had an overall impact on the quality level of the shipping industry and on the decrease of all types of incidents. Oil Company Vetting Inspections of Tokyo memorandum of the understanding on Port State Control 1993 MARPOL Special enhanced inspection programme (ESP survey) From 1990, and from 1993 standardi sed under the SIRE system Existing oil 1993 All ships entering ports of countries party to the memorand um 1993 (IACS) 1995 (IMO) Crude oil > DWT and > 5 years. Product > This is a voluntary measure introduced by oil companies when chartering vessels. The first oil company inspections may have started in the 1970s but this was on ad hoc basis and not on a significant numbers of ships. In the late 1980s oil company inspections became more prevalent, but the real proliferation of oil company vetting inspections followed the introduction of OPA90. Regulations with respect to Port State Control in Asia & Oceania To ensure that any deficiencies such as corrosion or wear and tear resulting from age or neglect are detected. The programme requires mandatory preplanning of surveys and has introduced strict on-board record keeping of surveys, inspections, It is generally believed that Oil Company Vetting Inspections have contributed to increased operational standards on. As such it is thought that they will have contributed to the improvements in all accident categories, except Non Accidental Structural Failure, as the Vetting Inspections do not involve any structural surveying. The introduction of the ESP surveys has certainly had a great impact on the decrease of the Non Accidental Structural Failure accidents. 5

Shipowning companies to hold a Document of Compliance and the ship to hold a Safety Management Certificate. The ISM Code has rationalized the existing procedures of shipping companies and harmonized the level and quality of their safety management systems. The ISM code represents significant progress which is thought to have had an impact on the decrease of all types of incidents SOLAS 1998 New ships Stricter requirements for protection of oil fuel lines (jacketed piping for high-pressure pipes, insulation of surfaces with temp. above 220ºC, screening). Impact on the prevention of fire incidents SOLAS 1997 All ships Ships' routeing systems may be made mandatory for all ships. This amendment had an impact on the prevention of the collision and grounding accident. 6

Safe access to tanker bows. Ships to be fitted with a system to ensure that the equipment necessary for propulsion and steering will be maintained or immediately restored in the case of loss of anyone of the generators in service. This convention may have an impact on the reduction of the number of grounding accident by making easier the salvage operations. However this impact remains limited for New oil Dedicated sea water ballast tanks to have efficient corrosion prevention system. This amendment will have an impact on the decline of the number of Non Accidental Structural Failure accidents. As this amendment involves new building, it will certainly take years to show results ILO C180 Seafarers' Hours of Work and the Manning of Ships Condition Assessment Program (CAP) 2002 All Ships Regulations concerning maximum hours of work, and minimal rest requirements Existing A voluntary measure promoted mainly by oil companies for ships they charter. It is applied for of over 15 years old. The CAP scheme was first introduced in 1991, initially by one classification society, and quickly followed by a second one. The scheme really took off in terms of ship numbers around Effects watchkeeping and emergency response, hence grounding, contact or collision events. CAP addresses the structural condition of and therefore any positive influence CAP may have is on Non Accidental Structural Failures. 7
