Novel offshore installation construction resource-combined type pontoon barge

Abstract

The invention provides an offshore installation construction resource-combined type pontoon barge. The combined type pontoon barge (1) comprises a flat plate ship body (2), a portal jib crane (3), a crane (4), a cantilever beam (5), an awler crane (6), a slide rail (7) and a removable deck (8), wherein the portal jib crane (3), the crane (4), the cantilever beam (5), the awler crane (6), the slide rail (7) and the removable deck (8) are arranged on the flat plate ship body, and at the same time, a left and right water ballast tanks (11), a fresh-water tank (12), a bilge tank (13), a hydraulic motive power station tank (generator tank) (14), a fuel oil tank (15), a ballast tank control tank (16), a dust tank (17) and a living tank (18) for meeting the living and residing requirements of 60 persons are arranged on the flat plateship body (2). The pontoon barge is mainly used for the transportation and the installation operation of large structures of ocean engineering, and can also be used for the installation of expansion bend parts, offshore pipe pavement construction operation and the like. The invention has the advantages that the shipping, the transportation and the offshore installation can be realized at the same time, the risk of offshore installation construction is reduced, the offshore construction resources are reduced, and the time is saved.

Description

technical field [0001] The invention belongs to the innovation of offshore installation and construction resources in the field of ocean engineering. Background technique [0002] Engineering barge refers to a ship that has no power propulsion device, no self-propelled capability, and is driven by a motor ship to engage in engineering operations. According to the function, it is divided into dredger, crane ship, piling ship, concrete mixer ship and ships for auxiliary operations. It is characterized by simple equipment, shallow draft, and large cargo capacity, and is mainly used for passenger and cargo transportation. With the increasing scale of offshore oil exploration and development, a single engineering barge in the general concept has a simple structure, relatively single function, and most of its main transportation functions cannot meet the needs of construction. According to the characteristics of the current marine engineering structure itself, to complete a cons...

Problems solved by technology

With the increasing scale of offshore oil exploration and development, the general concept of a single engineering barge has a simple structure, relatively single function, and most of the characteristics of transportation are more unable to meet the needs of construction.

According to the characteristics of the current marine engineering structure itself, to complete a construction operation, several ships with different functions need to be used at the same time, which increases the construction resources, increases the cost, and prolongs the construction period.
