摘要:
Provided is a locking apparatus for a damping device of a moonpool, which can automatically lock and unlock an opened state of the damping device of the moonpool. The locking apparatus includes: one or more first locking members installed in a sidewall of the moonpool; one or more second locking members installed in a side of the damping device; and a holding unit separably holding the first locking members and the second locking members when the damping devices are in the opened state.

The present invention relates to a floating unit for drilling operations in particular a drill ship, comprising a floating structure 2 which defines a main deck 3, above which a drill floor 4 is placed, and at least one drilling tower 5 having a box-like structure which extends above the drill floor 4 next to at least one moon pool 6, which vertically crosses the floating structure at the drill floor 4 as far as the bottom 8 of said floating structure. The drilling tower 5 is directly supported by a support structure 10 structurally integrated with the floating structure 2. The support structure 10 of the tower 5 and/or the tower 5 crosses the drill floor 4. The drill floor is structurally supported by the support structure 10 of the tower and/or by the tower itself.

Disclosed are a mooring system and a drill ship including the same. The mooring system according to an embodiment of the present invention includes a circular guide groove formed on a bottom surface of a hull and configured to use a center of the moon pool as a center thereof, a turret having a ring shape and inserted into the guide groove to rotate, and a bearing interposed between the turret and the guide groove to rotate with respect to the guide groove of the turret.

A dissimilar material joint (50) is formed by arranging a plurality of joint segments (44) consecutively in a longitudinal direction. Each joint segment (44) is formed by joining and integrating together a first member (51), an intermediate member (55), and a second member (54) by explosive welding. A groove (62) is formed in a joint end face of each joint segment (44), the joint end face being joined to another one of the segments (44), the groove (62) spacing apart an end face of the first member (51) and an end face of the second member (54) from each other in a stacking direction. In the dissimilar material joint (50), the end faces of the respective first members (51) of the joint segments (44, 44) that are adjacent to each other are joined together by welding, and the end faces of the respective second members (54) of the joint segments (44, 44) that are adjacent to each other are joined together by welding.

A device for diminishing flow resistance in a moon pool is disclosed. The device includes a guide structure (16) having a lattice shape. The guide structure includes horizontal guide plates (20), guide ramps (22), longitudinal reinforcing beams (24) and a hinge axis (H). The horizontal guide plates are spaced apart from each other along a longitudinal direction of a hull and arranged in rows along a lateral direction of the hull. The guide ramps are arranged in rows along the lateral direction and coupled to the respective horizontal guide plates. Front ends of the guide ramps are inclined upwards towards a bow side of the hull and spaced apart from rear ends of the adjacent fore horizontal guide plates. The longitudinal reinforcing beams support the horizontal guide plates and the guide ramps. The lattice guide structure is rotated around the hinge axis towards a transit position or a working position.

A composite structural laminate plate construction comprises two outer metal layers (1, 2), a form (10) between them and an elastomer layer (20) bonded to the outer metal layers (1, 2) and filling the space between them other than that occupied by the form (10). The form may be foam and may be in partial contact with the metal layers (1, 2).
摘要:
Gabarit de tamponnage (13,20,21) pour le passage de profilés de renfort structurel (11) sur structures navales, équipé d'une rainure est collé aux structures métalliques traversées (10) au moyen d'un matériau scellant, incombustible et élastique, qui est constitué par un produit à un seul composant à base de fibres. Avant de présenter le gabarit (13), on pose sur la surface de la structure métallique traversée (10), dans la zone prévue de superposition avec le gabarit (13), une couche (18) de matériau scellant, on présente le gabarit (13), en effectuant une pression sur celui-ci, puis on fixe plus solidement le gabarit (13) sur la structure métallique traversée (10) au moyen de points de soudure (14,15,16;22,23,24,25) puis, pour terminer, tout autour du périmètre du gabarit (13) on pose un cordon d'encollage (19).
摘要:
A composite laminate panel suitable for building containment vessels, and in particular, suitable for building double hull oil tankers. The laminate has two facing metal layers structurally bonded to a polyurethane elastomer core. The laminate is used in various hull components, such as the hull plates, longitudinal girders, transverse frames and bulkheads. The laminate is used to build the inner hull and outer hull, and may be used to build the structural supports between the inner and outer hulls. The innermost layer of inner hull contains the ship's cargo. The elastomer core of the inner hull laminate isolates the innermost hull skin from cracks, thereby preventing a loss of cargo such as oil into the environment, when the outer hull is pierced, penetrated or ruptured in an accident or grounding.
