Study On Shipping Agency Business Of Drilling Rig Towing At Anchorage Of Dalian Port

The rapid growth of oil demand in China, China's oil shipping market provides a good opportunity. At present, the development of the world's oceans has become a major issue; the marine economy has also become a new growth point of national economy. In particular the development of offshore oil and gas resources, the more compelling. The development of new oil and gas resources has become an inevitable trend to march the sea. Jack up drilling rig is maritime mobile drilling platform, because of its positioning capability and operational stability; it occupies an important position in the continental shelf waters of the oil and gas exploration and development. the marine mobile platform is a major offshore oil and gas exploration and development equipment, it is need for transportation when the offshore platform to replace position, delivery to the shipyard repairs, and will be built offshore oil operations by the shipyard to sea transport. there are now common methods used semi-submersible barge. drilling rig in the semi-submersible vessel loaded into the process, they will use tugboat towing semi-submersible drilling platform to the location of sites, and then to load the drilling rig. Therefore, Offshore drilling rig security on the towing of great significance.In this paper, tug towing offshore drilling rig for the study in Dalian anchorage of port. Care of the drilling rig of the calculation method of Resistance to drilling rig of stability and load lashing theory as the main basis for the development of relevant work and drilling rig towing program. In this process, we can draw on the drilling rig, solid towing and lashing line notes and essentials.By this author, hoping to provide some valuable experience and advice in later towing of drilling rig.
