Zusammenfassung:	A releasable guidepost for use on the seabed together with a fixed subsea structure is shown. The guidepost assists during lowering of a component from the surface of the water to the subsea structure to obtain a focused landing of said component at a predetermined location. The guidepost includes an upward (in the position of use) projecting end designed for engagement with the lowered component. The guidepost is of a light weight shell construction, in order to increase buoyancy during lowering thereof through the sea by use of an ROV. The light weight shell construction defines a cavity filled with a non-collapsible buoyancy material in at least part of the guidepost.
