Lift boats are the unglamorous vessels of oil and gas well servicing industry. They travel to the job site with three large cylindrical legs rising 150-250 ft. above the waterline. Once onsite, lift boats lower their legs to the seabed and raise their hull up to 100 ft. above the waterline to be even with the structure they are servicing to provide a stable platform for workers to transit from the lift boat to the project in which they are working. These versatile vessels can serve through the entire life of a oil or gas well from driving casing to provide a "path" for a jackup rig to drill through construction of the platform, repair and renovation of the platform to plug and abandonment of the well.
