    • An offshore well platform is towed in an upright condition to a well site by the use of a temporary flotation device. The flotation device mounts to a portion of the platform and is partially submerged, increasing the ability and buoyancy of the platform. At the site, the engagement of the flotation device shifts to a deploying position. In the deploying position, the ballast of the platform is increased to cause it to more deeply submerge. The flotation device remains at least partially surrounding the platform and floating while the platform moves downwardly relative to it. This provides lateral support if needed to prevent heeling while being submerged. The flotation device is disengageable from the platform when the platform is fully submerged.
    • 通过使用临时浮选装置将海上井平台以直立状态拖到井场。 浮选装置安装到平台的一部分并且部分地被淹没,从而增加了平台的能力和浮力。 在现场,浮选装置的接合转移到部署位置。 在部署位置,平台的镇流器增加,使其更加深入淹没。 浮选装置至少部分地围绕平台并且在平台相对于平台向下移动时浮动。 如果需要防止在淹没时倾斜,则提供横向支撑。 当平台完全浸没时,浮选装置可从平台脱离。
