Description
Technical Field
The invention relates to the field of crude oil barge-to-barge manufacturing, in particular to a living area sheet welding method for crude oil barge-to-barge.
Background
The traditional crude oil transportation generally adopts a combined mode of 'FPSO (floating production oil storage vessel) +shuttle tanker', and the shuttle tanker with good dynamic positioning performance can be relatively close to the FPSO to finish the crude oil transportation work in consideration of complex sea conditions under the combined action of wind, wave and current near the sea area of the FPSO operation. However, the international oil price is continuously running at present, the single-time transportation of crude oil in the transportation mode of the FPSO and shuttle tanker is small in quantity, the transportation cost is high, and particularly in the case of long-distance transportation, the defect is particularly remarkable, and the profit margin of a crude oil extraction company is greatly compressed.
Compared with a shuttle oil tanker, the VLCC (very large oil tanker) has larger single transportation quantity, and can greatly reduce the transportation cost of crude oil at sea. However, the conventional VLCC ship type has poor dynamic positioning capability, and if crude oil is transported close to the FPSO, the relatively steady state is achieved with the help of complex multi-point mooring and auxiliary ships, and high requirements are placed on the sea bed conditions of the operating sea area. Therefore, CTV (crude oil barge) has been developed to build a transfer bridge between VLCC and FPSO in order to meet the market demand.
The upper building part of the crude oil barge is usually provided with various crew living area cabins, and the living area is formed by welding thinner steel plates and frameworks based on the economic consideration of construction because the living area only needs to meet the daily life of crew and does not need to be provided with larger ship plane equipment. The platform base used as the floor slab in the living area is large in surface area, structural reinforcing members such as transverse beams and longitudinal beams are more, welding continuity is difficult to ensure, welding stress concentration is easy to occur, the processing efficiency in the manufacturing process is low, deformation is easy to occur, and larger assembly gaps can occur if deformation occurs, so that the assembly of the subsequent whole living area section is affected.
