Description

A kind of beveled structure of LNG-FSRU bows cargo hold

Technical field

The present invention relates to marine large-scale Floating Liquefied Natural Gas storage and regasification plant (LNG-FSRU) Ship Structure skill Art, more specifically to a kind of beveled structure of LNG-FSRU cargo holds.

Background technology

In nearly 5 years, the marine large-scale Floating Liquefied Natural Gas storage of research and regasification plant are risen successively in the world (LNG-FSRU), accordingly stored and regasifying liquefied natural gas base with replacing building on land.Marine LNG-FSU compares land Upper base, the construction period is short, and expense is low, and environmental-protecting performance is more preferable, is the high-end equipment of latest model of current international ocean engineering.At present The LNG-FSRU for not having more than 27 ten thousand steres also in the world puts into effect.

Without the cargo hold and stem structure for transforming LNG-FSRU as shown in Figure 1 and Figure 2, need are arranged according to cargo hold and bow Ask, isolate empty cabin 7 and be arranged on before bow Peak Tank 8, isolate empty cabin 7 by being arranged on the cargo hold passage deck 1 on top, first in cargo hold Plate 2 and be arranged on bottom 5 in the cargo hold of bottom, outside plate 6 forms；Bow main deck 4 is arranged on the top of bow Peak Tank 8.The goods The horizontal girder 3 and the bow main deck 4 of cabin passage deck 1 and bow main deck 4 not in sustained height, cargo hold area be not also right Position.Wherein, cargo hold passage deck 1 and goods flat 2 are to having certain distance, the horizontal girder 3 between the bow main deck 4 It is closer to the position of bow main deck 4.In these cases, cargo hold isolate empty cabin horizontal girder 3 and bow main deck 4 not In sustained height, it is impossible to ensure the effective transmission of load.

The content of the invention

It is contemplated that designing a kind of beveled structure of cargo hold, effectively solve cargo hold transverse bulkhead horizontal girder and bow main deck Not sustained height load problem of transmission, it is ensured that effective transmission of structural strength.

In order to achieve the above object, the present invention provides a kind of beveled structure of LNG-FSRU bows cargo hold, including is arranged on The horizontal girder isolated inside empty cabin and the bow main deck for being arranged on bow Peak Tank top, outside the end points and cargo hold of the horizontal girder Cant board connects, and the direction of the plate face of horizontal girder along bow main deck tilts upward, tiltedly interior to the bow main deck and cargo hold It is turned over downwards at the second knuckle point that shell phase is handed over, turns down into cargo hold the 3rd knuckle point that riser and the oblique inner casing of the cargo hold intersect It is horizontal-extending after place；The horizontal girder structure is symmetrical.

The present invention provides the beveled structure for the LNG-FSRU bow cargo holds that can be aligned with main deck, can effectively transmit bow Load between structure.The present invention effectively ensures the transmission of load by knuckle types horizontal girder, ensures structural strength, while reaches beautiful The effect of the beautification outdoor main deck of bow is seen, realizes shipbuilding attractive in appearance.The isolation being made up of between cargo hold and bow double-deck transverse bulkhead Empty cabin, isolate arrangement horizontal girder in empty cabin.Bow main deck is large area open deck, need to design camber：Height, two among being formed The low slanted deck of topside, avoids deck ponding.The present invention uses horizontal girder bending angle transition, avoids and is rolled over using bow main deck This transition structure in angle causes main deck out-of-flatness, centre are low ponding to be present, and transition structure increase in deck reduces deck cloth and installed The problem of standby effective area.The present invention can effectively solve LNG-FSRU cargo hold transverse bulkhead horizontal girder and bow main deck does not exist The problem of transmission of the load of sustained height, it is ensured that front-end geometry effectively connects.

Embodiment

As shown in Figure 3, Figure 4, in beveled structure of the present invention, the end points of horizontal girder 3 connects with the outer cant board 13 of cargo hold, Position of the plate face of horizontal girder 3 along bow main deck 4 tilts upward, and intersects to the bow main deck 4 inner casing 9 oblique with cargo hold It is turned over downwards at second knuckle point 11, turns down into cargo hold the 3rd knuckle point 12 that riser 14 and the oblique inner casing 9 of the cargo hold intersect It is horizontal-extending after place；The tiled configuration of horizontal girder 3 is symmetrical.The horizontal girder 3 is in addition to angled portion, remainder and bow The contraposition connection of main deck 4；Effectively ensure the transmission of load by knuckle types horizontal girder, ensure structural strength, while reach beautiful The effect of the beautification outdoor main deck of bow is seen, realizes shipbuilding attractive in appearance.

The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto, Any one skilled in the art in the technical scope of present disclosure, technique according to the invention scheme and its Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
