Problems solved by technology
However, hoisting at the wharf stage is risky and difficult, and it is easy to cause production accidents
[0007] However, on ships that use liquefied petroleum gas as fuel, the fuel tanks are often located in non-open areas, and the lifting of the pump tower after the completion of the containment system will cause a huge delay in the loading of the superstructure
It will have an extremely adverse impact on the shipyard's control of the dock cycle, which will greatly limit the increase in the shipyard's production capacity and increase additional operating costs.

The invention provides a method for installing a triangular mast of a pump tower of an MARK-III type enclosure system, which focuses on the precondition of hoisting the pump tower in advance, the operation process, detailed hoisting solution and subsequent ending, and simultaneously overcomes various problems generated by hoisting in advance and the problem of long construction period of the enclosure system. For the ship type with a large-scale steel structure at the upper part of a hatch coaming, the pump tower is hoisted in advance, so that the carrying time can be greatly shortened, the dock period is shortened, a ship enterprise for building an LNG ship or an LNG fuel ship can be guided to hoist the pump tower in advance, the shorter carrying period is ensured, the richer constructionperiod is provided for a liquid cargo system CHS and a fuel gas system FGSS, and great significance is achieved for the period and cost control of a shipyard.
Description
technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a method for installing a pump tower triangular mast of a MARK-III containment system. Background technique [0002] GTT MARK-III / MARK-III FLEX containment system is a membrane containment system widely used in LNG carriers and dual-fuel ships. [0003] Pump tower hoisting is a major technical difficulty in the construction of liquefied gas carriers and liquefied gas powered ships, and is also an important production node. Pump tower hoisting marks the CHS (cargo handling system) or FGSS (fuel The start of construction of the gas supply system. Premature hoisting of the pump tower will cause a lot of inconvenience to the construction of the cabin enclosure system, so the pump tower hoisting is generally arranged after the installation of the main shielding in the cabin is completed or is about to be completed. [0004] The hoisting of pump towers of liquefied gas tran...
