The jackets, with aluminum sacrificial anodes for cathodic protection (CP) of the immersed zone, were launched in March 1995. In May 096 a CP survey showed that, after almost one year of service, a low polarization level had been achieved and some extended unprotected zones existed; mainly in the deepest part of the Platform II. Further to this, a joint activity was decided in order to assess the need of a possible retrofitting of the CP systems. The results of the activity carried out are dealt with, including technical and economical comparisons amongst several retrofitting options, both with sacrificial anodes and with impressed current systems. The adopted solution is illustrated and data are reported on the level of protection presently achieved.展开更多

It has become a controversial sea area due to the loopholes in the modern law of the sea. It is competed by neighboring countries for its interests, which exacerbate the tense situation in China＇s enforcement of maritime rights protection and poses the serious threat to our country＇s sovereignty over the South China Sea. The article takes the South China Sea controversial maritime rights enforcement model as the starting point. It contrasts the status quo of maritime rights enforcement system both at home and abroad, and analyzes the existing laws and regulations of maritime rights protection system in our country, such as the imperfect laws and regulations, the unreasonable establishment of law enforcement agencies and the imperfect law enforcement system. It also puts forward the strategy and idea of perfecting the law enforcement system of maritime rights protection in our country, which is of far-reaching significance to the strategy of safeguarding the maritime rights and interests of China and building a maritime power.展开更多
