The invention provides a shallow-draft geophysical prospecting workboat. A boat body is provided with a bulbous bow, the width of the bulbous bow is larger than the height of the bulbous bow, the bulbous bow is provided with a side surface and a bottom surface, on a cross section passing through the bulbous bow, the side surface and the cross section intersect at a first curve, the bottom surface and the cross section intersect at a second curve, and the curvature of the first curve is larger than that of the second curve. The bottom surface is smoothly connected with the bottom of the boat body and intersects with a middle longitudinal section at a third curve, the curvature of the third curve is gradually reduced from the bow direction to the stern direction, and the width of the bottom surface is gradually increased. The boat body is provided with a DP propelling system, a column-mounted air gun seismic source system and a node folding and unfolding system. According to the shallow-draft geophysical prospecting workboat disclosed by the invention, the boat body is provided with the wide and flat bulbous bow so that the boat body has the ability of sailing in a shallow water area, a wave-making resistance generated during sailing of the boat is improved, meanwhile, the specific gravity of a drainage volume distributed at a head part is increased, and the stability and seakeeping of the boat are improved; and a heaving phenomenon under the action of stormy waves can be resisted.
本发明提供一种浅吃水物探作业船,船体具有球鼻艏,球鼻艏的宽度大于高度,球鼻艏具有侧面和底面,在经过球鼻艏的横剖面上,侧面与横剖面相交于第一曲线,底面与横剖面相交于第二曲线,第一曲线的曲率大于第二曲线的曲率。底面与船体底部平滑连接,与中纵剖面相交于第三曲线,第三曲线的曲率从船艏方向向船艉方向逐渐减小,且底面的宽度逐渐增大。船体设有DP推进系统、列装气枪震源系统和节点收放系统。本发明公开的一种浅吃水物探作业船,船体设有宽扁平的球鼻艏,使船体具有浅水域航行的能力,不仅改善船舶航行时的产生的兴波阻力,同时增加分布在首部的排水体积的比重,提高船舶的稳定性和耐波性,有利于抵抗风浪作用下的垂荡现象。
