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 present invention provides a method for installing a pump tower delta mast of a MARK‑III type containment system, focusing on the preconditions, operation process, detailed explanation of hoisting, and subsequent finishing of the pump tower hoisting in advance, and at the same time overcoming various problems caused by the hoisting in advance , to overcome the problem of long construction period of the containment system, for ships with large steel structures on the upper part of the hatch enclosure, hoisting the pump tower in advance can greatly shorten the loading time and reduce the docking period, and can guide the construction of LNG ships or LNG fuel ships It is of great significance to the shipyard's period and cost control that the company will carry out the pump tower hoisting earlier to ensure a shorter loading period and give the liquid cargo system CHS and gas system FGSS a more abundant construction period.
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...
