The present invention relates to a method of providing an adjustable arm davit apparatus with height adjustable feature including, a base member, a shock absorber, a boom member, an adjustable arm, a winch assembly and a cylinder assembly. The boom member comprises a first member hingedly mounted on the base member and a second member mounted on the first member to adjust a height of the apparatus via the cylinder assembly disposed at the boom member. The adjustable arm is engaged to frontal ends of the boom member. The winch assembly positioned on the boom member for supplying a cable via a plurality of pulleys to attach the target object. The winch assembly is actuated to raise or lower the target object from the target location.

A system and method of extracting a tube from the water by pulling the tube up a pair of elongated rails extending aft of the stern of a vessel and positioning the tube between a tube containment arm disposed above each of the elongated rails so that the tube is pressure fit therein. The pair of elongated rails can be pivoted up and out of the water for transportation and storage. The elongated rails and the tube containment arms can be telescopic.

The invention provides a system for transporting object from a sea level position to an elevated position on a structure, wherein the sea level position is movable in relation to the elevated position. The system comprises an elongated guide device configured to be arranged to the structure in one end and to extend below the sea level with a second end, an attachment device configured to be arranged on said object and for attaching said object to the elongated guide device, wherein the attachment device is configured to allow a relative movement between the attachment device and the elongated guide device along a first direction parallel to the extension direction of the guide device and a lifting device configured to transport the object from the sea level position to the elevated position. The system is characterized in that a weight is arranged to the second end of the guide device below the sea level for stabilizing the guide device, wherein the second end is a free end and the weight is a free weight.
