  • Publication number: 20230211857
    Abstract: The present invention provides a floater structure. The floater structure is used for bearing the tower of wind turbines, especially for the offshore wind turbines. The floater structure is constructed via a main column, two off columns and a pontoon. The off column is connected to any other main column and the off column via a horizontal bracing, and the pontoon is connected to the main column and the two off columns. The shape of the pontoon is triangle, and three corners of the triangle are round corners, polygon corners, or the combinations thereof.

  • Patent number: 9453276
    Abstract: Processes for protecting steel chains from corrosion and steel chains thus protected are provided. The process includes using finite element analysis to determine stress levels within links of a steel chain having a plurality of connected links. Regions of each link of the chain corresponding to high stress levels are identified. Target areas corresponding to the regions identified are indicated for coating each link of the chain with a sacrificial coating. Thermally sprayed alumina can be used as the sacrificial coating.

  • Patent number: 9221521
    Abstract: Disclosed are platforms adapted to be mounted onto anchor handling vessels (AHVs) and AHVs useful for replacing a used wire rope segment or for installing a new wire rope segment in a mooring line which can be used for mooring a floating vessel such as a floating storage and offloading (FSO) vessel.

  • Publication number: 20150027717
    Abstract: An apparatus, system and process for deployment of subsea drilling equipment through a moon pool of a drilling vessel is disclosed. The drilling equipment may include a subsea mudlift pump (MLP) that is configured to be deployed below the surface of the ocean and is adapted for conducting dual gradient drilling (DGD) operations. In the apparatus and process, the MLP may be suspended temporarily aboard the vessel by a holding mechanism. The MLP may be combined first with a lower marine riser package (LMRP) prior to suspension of the MLP and/or MLP/LMRP aboard the drilling vessel. An equipment combination, comprising at least a MLP and a LMRP, may be with a BOP, the mating occurring at a position below the surface of the ocean. In one aspect, the BOP may be separately deployed into the ocean, and then subsequently mated subsea with the LMRP and/or a MLP/LMRP combined equipment package.

  • Publication number: 20140017013
    Abstract: Disclosed are methods for replacing a used wire rope segment or for installing a new wire rope segment in a mooring line useful for mooring a floating vessel such as a floating storage and offloading (FSO) vessel. The methods utilize platforms adapted to be mounted onto anchor handling vessels (AHVs) for severing the used wire rope segment and connecting the new wire rope segment thereon.
