Table 10.9 lists some common zinc anode alloys. In three cases aluminium is added to improve the uniformity of dissolution and thereby reduce the risk of mechanical detachment of undissolved anode material . Cadmium is added to encourage the formation of a soft corrosion product that readily crumbles and falls away so that it cannot accumulate to hinder dissolution. The Military Specification material was developed to avoid the alloy passivating as a result of the presence of iron . It later became apparent that this material suffered intergranular decohesion at elevated temperatures (>50°C) with the result that the material failed by fragmentation". The material specified by Det Norske Veritas was developed to overcome the problem the aluminium level was reduced under the mistaken impression that it produced the problem. It has since been shown that decohesion is due to a hydrogen embrittlement mechanism and that it can be overcome by the addition of small concentrations of titanium". It is not clear whether...

External verification the CER has been appraised by Det Norske Veritas. This appraisal included a review of data from all operating sites, and visits to sites in the UK, Malaysia and South Africa to evaluate conditions on the plant. In particular, the auditors remark on... 

Det Norske Veritas states that it made some detailed recommendations for ways to enhance the site and Group environmental reports , but these are not given in the CER. Tioxide s willingness to take on these and previous years recommendations is also recognised.

Based on the assumption that the soil is perfectly plastic material, a wide scatter of variations have been proposed by various authors, as shown in Figure 10.5. Notably, recommendations from American Petroleum Institute (API RP2A, 2000) and Det Norske Veritas (1977) are very conservative. Of the values shown in Figure 10.5, that of Berezantsev et al. (1961) is considered to be the most reliable (Nordlimd, 1963 Vesic, 1965 Tomlinson, 1977 Canadian Foimdation Engineering Manual [CFEM], 1978).

The materials tested were 25-, 35-, 50-, and 80-mm-thick 5083-0 plates, which were manufactured by ordinary industrial processes and sufficiently met the requirements of applicable ASTM and NV (Det Norske Veritas) specifications. The fracture tests were conducted mainly on 25-mm-thick plates. The 35-, 50-, and 80-mm-thick plates were used to investigate the effects of plate thickness on fracture strength.

In addition, information is available from several reputable sources, including the World Offshore Data bank (WOAD) of Det Norske Veritas (DNV), which contains data and analyses on more than 6,000 accidents from 1970, the SINTEF Offshore Blowout Data Base on major blowouts and spills since 1955, and periodic studies done for Oil and Gas UK on accidents dating back to 1990. Such a comparative analysis would be useful to the new DOI regime in which BOEM and BSEE are expected to develop regulatory reforms and to their counterparts in Norway and the United Kingdom as well. Performance indicators and the reporting and evaluation of safety-relevant data are discussed further by Blakstad in Ghapter 9.

For novel technologies, it may sometimes be difficult to determine which standards are applicable and to what extent certain requirements are relevant. On this basis DNV( in cooperation with industry partners, developed the DNV-RP-A203 Qualification procedures for new technology in 2000, (Det Norske Veritas, 2001). This recommended practice has previously been presented at an ESReDA seminar, (Kortner, 2004).
