A liftboat is a self-propelled, self-elevating vessel with a relatively large open deck capable of carrying equipment and supplies in support of various offshore mineral exploration and production or offshore construction activities.
Liftboats look like a barge with three or four legs. Brothers Lynn and Orin Dean are credited with inventing the liftboat in 1955 when they combined the design of a jack-up oil rig with an offshore supply boat.
A commercial lift boat had begun to lower its legs onto the seafloor off the Louisiana coast during bad weather and a crew member had turned the vessel into heavy winds when it capsized last month, according to a preliminary report by the National Transportation Safety Board released on Tuesday. Although the N.T.S.B.
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast.
A liftboat is a self-elevating, self-propelled, offshore supply vessel. Liftboats have been used in the Gulf of Mexico to service and supply offshore platforms as well as performing other offshore operations for the Oil & Gas industry.
NEW ORLEANS (AP) — The offshore service vessel that capsized in the Gulf of Mexico in a deadly April disaster is cracking and will have to be brought ashore in sections, the U.S. Coast Guard said Wednesday.
According to the NTSB report, when the legs began to descend, the crewmember at the helm attempted to turn the vessel into the winds. Before the turn was completed, the Seacor Power heeled to starboard and capsized. Several personnel were able to escape out onto the exposed port side of the Seacor Power deckhouse.
The man, Dwayne Lewis, was one of six survivors from the lift boat, called the Seacor Power, that capsized during a storm on April 13, killing 13 people. A lift boat is a work vessel with legs that can jack up and turn the boat into a platform above the water.
It is owned and operated by Seacor Marine, which is based in Houston but has an office in Houma. The Seacor Power was built in 2002 and has a crew and passenger capacity of 48, according to the owner's website. It has the ability to work at a maximum depth of 195 feet and is equipped with two 185-ton cranes.
While you may instinctively raise the boat as high above the water as possible during a storm, it is better to not do it. There is the risk of your raising the ship till the lifting platform, or of the rack hitting the frame. Either only leads to snapped cables and possible personal injury or boat and lifts damage!

The 175-foot lift boat Seacor Power carried nine crew members, two galley staff and eight offshore workers when it overturned in the Gulf of Mexico during hurricane-force winds April 13, the report said.
What Type of Boats Are Most Likely to Capsize? Capsizing occurs most often with small boats like canoes, kayaks, and sailboats. This is because small boats are more likely to become unstable since they are built to only hold a limited amount of weight.
The skipper should turn the boat to port. This will move the stern (and the propeller) to starboard and away from the person in the water. Do not go into the water to assist the person unless absolutely necessary.
Ships are built so that they can't easily flip over – or capsize. Whether a boat capsizes or not has a lot to do with something called its centre of gravity. We think of gravity as a force that pulls things downward (toward Earth's centre), but it doesn't always work like that.
What Prevents a Sailboat from Tipping Over? In conjunction with other weight, the keel or centerboard is primarily what keeps a boat from capsizing. This is essentially called ballast. There is ballast in the keel, and there is also usually ballast in the hull itself.
All sailboats need an optimum of “X” amount of power. A certain amount of heel allows the boat to sail on its lines, gives the rudder bite, and helps create lift. (That's why you will see racing crews huddled on the leeward rail in light air to induce heel.)
Without having the winds in your sails, the boat will not move forward. Instead, you'll only drift along and get stuck in the neutral. Worst still, you can easily capsize. As such, it's of great importance to have a good grasp of how the wind works in propelling a sailboat and what you can do without it.
Yachts can tip over, and they can sink just like any other type of boat. However, some yachts can capsize and sink more easily than others. The size of the yacht and the draft plays an important role when it comes to capsizing.
Yes, sailboats can flip or roll over, which is also referred to as capsizing. To prevent this from happening, make sure you do the following: Don't ride your sailboat in inclement weather, including strong winds, rains, lightning, and thunder.
The act of reversing a capsized vessel is called righting. If a capsized vessel has enough flotation to prevent sinking, it may recover on its own in changing conditions or through mechanical work if it is not stable inverted. Vessels of this design are called self-righting.
Boats typically spit out water to keep the bilge free of water. Water builds up over time inside the bilge and the bilge pump automatically pumps the water out again. Often, when boats are spitting out water, it is because they are expelling water that has built up in the bilge of the ship. What Is The Bilge Of A Boat?
