JPS57130888A - Semi-submerged work ship associated with elevating work table - Google Patents

Abstract

PURPOSE:To achieve a work ship where the works such as the oversea bridging work can be performed efficiently, by providing a work table on the top of an elevatable rig penetrating through the on-the-water hull and the submerged floating member thereby adjusting the height of the work table optionally. CONSTITUTION:The hull 4 located on the water and the floating body 9 located in the water are coupled through a seath 8 surrounding the rig 2, a coupling section 20, etc. where a plurality of rigs 2 are provided to pass through the seath 8 and penetrate through the hull 4 and the floating body 9, and when driving a pinion 7 it will be lifted or lowered by a rack provided in the longitudinally direction. A work table 1 is provided on the top of said rig 2 and a crane 11, winch 12, etc. needed for the work are equipped on the table 1. When lifting/ lowering the rig 2 thereby lifting/lowering the work table 1, various works such as the oversea bridging work can be performed efficiently.
