Abstract: A process for pipeline installation in shallow or very shallow water. The process includes trench excavation used for positioning/guiding pipes (“pre-trenching”); optional dragging of the pipes during the pre-trenching; cleaning and maintenance of the trench in the dragging; underground insertion of the pipes positioned at a required level (“post-trenching”); possible covering of the inserted pipes (“back-filling”). The operations are effected by coordinated use of vehicles of: a tracked transport vehicle or a vehicle with tires; an autonomous power and control module to power the vehicle, equipped with an operator cabin, being either positioned on the vehicle chassis or detached and placed on a floating craft, connected to the vehicle by an umbilical duct. The vehicles are assigned to transport one or more equipment items each having one of the following functions: “pre-trenching”, “trench maintenance”, “post-trenching”, possibly dragging and/or “back-filling”, so that all the equipment having the above functions is present within the whole group of vehicles used.

Abstract: A process and apparatus for installing the enbloc superstructure of an offshore platform on the fixed legs emerging from water of the lower structure or jacket including loading the whole superstructure on a vertically movable support platform provided on the deck of a semisubmersible raft or barge, completely submerging the raft in the vicinity of the jacket, the stability being maintained by vertical buoyancy tanks on the raft deck, and lifting the support platform and the superstructure by activating related hydraulic lift cylinders, to a height higher than that of the protruding ends of the jacket leg, independently from wave-motion of sea. Subsequently, cylindrical lift pillars slide, by means of hydropneumatic jacks, within tubular columns provided in the superstructure until the conical ends of the pillars enter corresponding seats in the jacket legs and, during a moment of smooth sea, the superstructure is lifted to the desired height using the hydropneumatic jacks, while at the same time, the support platform is rapidly lowered, and the raft is ballasted.
