Abstract

A method of initiating laying of an elongate flexible product such as a lightweight pipeline on the seabed comprises tensioning the product between an anchored termination head and an installation vessel. A sag bend curvature is imparted to the product by weight added locally to the product at a sag bend region. This orients the termination head, and a section of the product adjoining the termination head, toward the horizontal while they remain above the seabed. The invention aims to reduce or eliminate the need for an additional buoyancy element when initiating a lightweight flexible product towards a subsea anchor point as well as increasing the operational sea state for laying the subsequent tie-in loops
