A marine pipelaying vessel with a pipeline stinger connected to said vessel, preferably pivotable, and forming a downwardly directed support for pipeline to be laid. The vessel further includes a stinger suspension assembly between the stinger and the vessel from which the stinger is suspended at least during operation, preferably the stinger suspension assembly allowing to lower and raise said stinger. The stinger suspension assembly includes a sacrificial stinger impact absorber which is adapted to absorb impact energy resulting from a violent stinger motion, e.g. induced by a freak wave. Preferably, the impact absorber forms an elongatable structure, e.g. a telescopic structure, which is elongated under impact energy absorption.
