The floating installation method of offshore platform topsides has become an effective installation method since the 1980s. After years of practice and exploration in the industry, not only the weight of the installation structure is increasing, but also the installation method is constantly challenging the worse construction sea conditions.The floating method solves the contradiction that the module construction cannot be expanded due to the limitation of lifting capacity, and improves the efficiency of platform construction
(1) The incoming end must be aligned with the jacket notch;(2) The collision force between the fender and the jacket must be less than the bearing limit of the jacket and the fender itself;(3) There shall be no collision between the installation leg of the topside and the jacket leg during ship entry;(4) The longitudinal and transverse motions and yaw angles of the installation vessel must be controlled within a certain range.When the boat entry operation is completed
The performance and advantages of the product are as follows: molded foam board This product has introduced foreign foam technology, and the foam density is uniform, with a density of 0.3-1.0g/cm3. The product is soft, light, good resilience, strong tensile force, high strength, odorless, tasteless and non-toxic.Long service life, high temperature resistance can reach more than 300 ℃ without deformation.Features: 1. UV resistant and ozone resistant
Can silicone foam?Certainly.It may be around you, but you may regard it as a sponge when you see it, because it looks like it and feels soft.Foamed silica gel belongs to additive silica gel, and two-component additive silica gel.It consists of two parts: component A is silica gel and component B is curing agent;Mix the two components in 1:1 ratio
Rubber fenders are widely used in navigation, and also have a strong role in use. They can be divided into many types, such as cylindrical rubber fenders, semicircular (D-type) rubber fenders, drum rubber fenders, and inflatable berthing balls. What are their functions?What is the scope of application?Let's take a look.Each rubber fender has its own difference
In fact, there are many thermal insulation materials in the market, but polyurethane foam board is one of the three common internal wall thermal insulation materials.It is a special polyurethane product that can be filled with polyurethane prepolymer, foaming agent, catalyst and other components in a pressure resistant aerosol tank.When the material is ejected from the aerosol tank, the foamed polyurethane material will rapidly expand and solidify with the air or the moisture in the contacted matrix
As a polymer material with excellent performance, polyurethane thermal insulation material has become the fifth largest plastic after polyethylene, polyvinyl chloride, polypropylene and polystyrene, and the global total output has exceeded 10 million tons/year.In recent years, China's polyurethane industry has made great progress, and has been widely used in refrigerator, container, leather, shoemaking, textile and other fields.Of course, in our
