On March 17, Norwegian geophysical company Petroleum Geo-Services (PGS) officially received its latest Ramform Titan-class 3D seismic survey vessel (ship-type shipyard trading) "Ramform Tethys" from Mitsubishi Heavy Industries (ship hangar) Nagasaki Shipyard.
   The “Ramform Tethys†3D seismic survey ship is the world's first and most efficient 24-cable 3D seismic survey ship (ship type shipyard). In order to carry enough cables at the stern, the hull is very strangely constructed. The waist triangle is one of the most exotic ships in the world.
   The "Ramform Tethys" is 104 meters long and has a stern width of 70 meters. Its huge rear deck is ideal for installation and towing equipment for seismic research. The cost is about $285 million per ship.
   “Ramform Atlas†can carry 6,000 tons of fuel and related equipment, equipped with 24 cables and 12 kilometers of cables (purchased by the product library), and the sensors on the cable (purchased by the product library) can collect relevant data within 12 square kilometers, which is almost equivalent to 1500. The area of ​​the football field. The boat is equipped with safe and comfortable rooms, including 60 single cabins and 10 double cabins for up to 80 people.
   It is reported that PGS has ordered a total of four Ramform Titan-class survey vessels, and the "Ramform Tethys" is the third one. Meet the criteria for seismic survey vessels for the next 20 years. The first ship "Ramform Titan" was delivered in April 2013 and the operation was very successful. The unique design of the hull of this series of ships has only one purpose: to collect the maximum amount of seismic data quickly, safely and reliably. Compared to the first two ships of the same series "Ramform Atlas" and "Ramform Titan", the "Ramform Tethys" has a higher output and the rear deck has been further optimized. The ship thus became the new flagship of PGS.
   Previously, PGS had postponed the delivery of the last two 3D geophysical survey vessels built at Mitsubishi Heavy Industries. The two new ships are the “Ramform Tethys†and “Ramform Hyperion†delivered respectively. The delivery period was originally scheduled for the first half of 2015 and is currently extended to the first and third quarters of this year.
   According to PGS, “Ramform Tethys†will travel to Europe, where many customers have expressed strong interest in the new ship.
Rutile Titanium Dioxide
Rutile Titanium Dioxide is used in coatings, plastics, paper, printing inks, chemical fiber, rubber, cosmetics and other industries. It has a high melting point and is also used to make refractory glass, glaze, enamel, clay, high temperature resistant laboratory utensils, etc.
At the same time, titanium dioxide has a good UV shielding effect, and is often incorporated into textile fibers as a sunscreen. Ultra-fine titanium dioxide powder is also added to sunscreen cream to make sunscreen cosmetics.
Titanium dioxide is not only used as a coloring agent in the rubber industry, but also has the functions of strengthening, anti-aging and filling. Titanium dioxide is added to white and colored rubber products. It is resistant to sunlight under sunlight, does not crack, does not change color, has high elongation and is acid and alkali resistant. Titanium dioxide for rubber is mainly used in car tires, rubber shoes, rubber flooring, gloves, sports equipment, etc., generally anatase type. However, when used in the production of automobile tires, a certain amount of rutile products are often added to enhance the anti-ozone and anti-ultraviolet capabilities.

Rutile titanium dioxide
Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of fragrant powder use titanium dioxide instead of lead white and zinc white. You only need to add 5%-8% of titanium dioxide to the fragrance powder to get a permanent white color, making the fragrance smoother, having adhesion, absorption and hiding power. In gouache and cold cream, titanium dioxide can weaken the greasy and transparent feeling. Titanium dioxide can also be used in various other spices, sunscreens, soap flakes, white soap and toothpaste.
The glaze made of titanium dioxide has strong transparency, low quality, strong impact resistance, good mechanical properties, bright colors, and is not easy to be polluted. Titanium dioxide for food and medicine is titanium dioxide with high purity, low heavy metal content and strong hiding power.
