On May 26, the world’s first M350 offshore floating production storage and unloading ship (FPSO) «Bacalhau», jointly developed and designed by Dalian Shipbuilding and Mitsui Marine under China Shipbuilding Group, was officially delivered, realizing a major breakthrough in China’s floating production storage and unloading ship shipbuilding industry.

The «Bacalhau» floating production storage and unloading vessel is the seventh floating production storage and unloading vessel built by Dalian Shipbuilding. It is also the first cooperation between Dalian Shipbuilding and the world’s general contracting company Mitsui Ocean, as well as the world-renowned oil company Aquino, in the construction of a new floating production storage and unloading vessel.
The «Bacalhau» has transformed from concept to practice, from drawings to actual ships, fully adhering to the concept of full life cycle informatization and digital management, achieving full three-dimensional design and visual construction. It is the world’s first ultra large marine engineering project designed using the latest specifications of Det Norske Veritas, which can meet the special marine environmental conditions of Brazil, West Africa, Australia and other regions, and is suitable for oil and gas development operations in multiple sea areas around the world, And it can significantly reduce the operating costs of homeowners.

This project can be used for oil extraction, oil and gas separation, oily wastewater treatment, power generation, heating, and storage and transportation of crude oil products. It is a comprehensive large-scale offshore oil production base that integrates personnel living and production command system.
The project is classified by Norwegian Veritas, flying the Bahamian flag, and has the world’s largest volume, scale, and scale parameters. The ship has a total length of 364 meters, a molded width of 64 meters, a molded depth of 33 meters, a designed draft of 22.65 meters, a displacement of over 460000 tons, and a deck area of 17400 square meters, equivalent to three standard football fields. It can process 220000 barrels of crude oil per day, equivalent to a 10 square kilometer onshore oil and gas processing plant. Among them, the weight of the oil and gas processing upper module reaches 50000 tons, with a total of 34000 pipes on board, weighing about 4000 tons. The total length of the cable is about 800000 meters, equivalent to the straight-line distance from Dalian to Shanghai. The coating area is approximately 880000 square meters, and the construction volume of each profession is three times that of ordinary ultra large oil tankers (VLCC).

The project successfully applied various long-term anti-corrosion materials such as titanium alloy pipes, heat-resistant alloy pipes, super bidirectional stainless steel pipes, and improved fiberglass steel pipes used in fire protection systems, breaking through the challenges of welding, coating, and installation processes. It achieved that the platform only requires low maintenance in the oil field, and can meet the requirement of 30 years of non docking. There are 22 cargo oil tanks with a full load storage capacity of 2 million barrels. The operation mode of double export oil transportation is adopted, which is flexible and can meet different operational needs.
It is reported that the ship will operate in the Santos Basin off the coast of S ã o Paulo, Brazil, and is currently the largest floating production and storage vessel in Brazilian waters with the largest production capacity and reserves.
