A lifting system and a method of installing a lifting frame for lifting a subsea pipeline has paired subsea foundations spaced apart from each other by a gap through which the pipeline extends. A removable lifting frame is mounted on the foundations to bridge over the pipeline disposed in the gap. The lifting frame comprises a pair of feet that are cooperable with respective support formations on the foundations. One support formation defines a hinge component to restrain one of the feet for pivotal movement. The other support formation defines a platform on which the other foot can rest in various positions within a support area. This compensates for differences in level, spacing or alignment between the foundations. The lifting frame can be transferred to another location by dismounting it from a first pair of foundations and then mounting it onto a second pair of foundations in a corresponding manner.
