A module for retrofitting a boat for collection of floating biomass has a telescoping beam that spans the width of the boat and connects to aft-ends of levers that rest on the gunwales. The telescoping beam extends beyond both gunwales such that outboard net holders can be disposed thereon. Nets are attached to and held open by the net holders. The nets are at least partially submerged and fill with sargassum as the boat moves forward. Longitudinal drag forces are resisted by chains that connect the levers to the bow. Torsion around the telescoping beam is resisted by pretensioned straps that pass under the boat and over the aft-ends of the levers, which extend towards the bow to minimize strap tension and reaction force against gunwales. Horizontal moments in the outboard portions of the telescoping beam are absorbed by the inboard portion of the telescoping beam.

A hull-mounted installation conversion method in which some or all of first-use units placed on a hull and constituting a first-use installation are removed from the hull, and then second-use units are placed on the hull to construct a second-use installation. For example, the first-use units are medical units, and the first-use installation is a medical installation. Alternatively, the second-use units are medical units, and the second-use installation is a medical installation.

A floating vessel equipped with a power plant includes a hull and a process deck arranged on a portion of the hull above compartments within the hull. The power plant includes a fuel source and at least one electrical power generator driven by a gas turbine; the fuel source arranged for providing fuel to the gas turbine. Per gas turbine, the floating vessel is equipped with a steam production unit coupled to the gas turbine exhaust for receiving heat to produce pressurized steam. Per each steam production unit, the floating vessel is equipped with at least one secondary power generator driven by a steam turbine, which is coupled to the steam production unit for receiving steam. Each gas turbine and steam production unit are positioned on the process deck, and each secondary power generator and steam turbine are positioned under the process deck in the one or more compartments.

A floating platform, the platform including a plurality of floating chambers, wherein each chamber comprises a plurality of shipping containers, each container having a door at a first end and an opposing panel at a second end, the containers placed one above the other such that a door of one container is connected to an opposing panel of another container.

A floating offshore wind turbine assembly unit useful for assembling or maintaining wind turbines at an offshore location is disclosed. The floating offshore wind turbine assembly unit may include a first vessel spaced a distance apart from a second vessel, and an extended deck coupled to the first vessel and the second vessel. The extended deck is positioned in the distance between the first vessel and the second vessel, and the extended deck is configured as a dry dock disposed or movable to a height above a sea level. In some embodiments, the extended deck or a portion thereof is movably coupled to the first vessel and the second vessel. For example, the extended deck or a portion thereof is movable between a submerged or near sea level position and a position above a sea level.

A structural block is fabricated with necessary components and structure for LNG storage and/or process. The structural block may be an LNG tank with the same configuration as that in an LNG carrier. The structural block may also be a regasification plant or a liquefaction plant to be used for LNG process. An existing vessel, e.g. an LNG carrier, is cut apart to form a forward section and an aft section. The forward section and the aft section are moved away from each other to form a space therebetween. The structural block is then placed into the space and jointed to the forward and aft sections, by welding for example, to form an integrated new vessel. The structural block provides the new vessel with increased LNG storage and transportation capabilities as well as regasification and/or liquefaction process facilities to meet the increased demand for LNG storage, transportation and processing.
