| 摘要 |
The invention relates to a marine vessel having a hull structure (2) with a bottom surface (21). The marine vessel has an internal compartment (3), a so-called moon pool or keel cavity. The internal compartment (3) extends downwards to the bottom surface (21) of the hull structure (2) and is provided with a closure mechanism (4). In order to eliminate the risk of inflow of unwanted objects, such as ice formations (IF), into the internal vertical compartment (3), the closure mechanism (4) includes at least two pairs of turnable hatch elements (42, 43, 45, 46), which are arranged to form an extension (5) of the internal compartment (3) below the bottom surface (21) of the hull structure (2) of the marine vessel (1). |
