Abstract: A floating, self-propelling, self-ballasting, pivotable bridge system is described. The bridge has a main bridge body with a pontoon-like structure. One end of the bridge has a pivoting system comprising complementary pivot plates, one attached to the bridge and the other on land with a pivot pin attaching them at a pivot point. The other end of the bridge has a releasable locking mechanism. The bridge has ballast tanks for raising and lowering its level in the water. The bridge also has thrusters for propelling itself through the water when it pivots from a closed position spanning a waterway to an open position allowing boat traffic through a waterway.

Abstract: Novel precast concrete boxes are disclosed which can be assembled together and/or with structural shapes disclosed in U.S. Pat. No. 5,697,736 to form waterfront structures such as seawalls, boathouses and the like. The boxes can be sized and proportioned so as to be conveniently assembled in such structures and to be easily transported via intermodal transportation media. Novel methods of waterborne transport and installation of the boxes are disclosed. Shellfish habitats based upon the boxes are also disclosed.

Abstract: A clamped-down bridge comprises a superstructure supported by pontoons, each end of the bridge being fixedly secured to the bottom by means of anchors and anchor cables and clamped down to the expected maximum load by means of sinkers and sink cables. The anchor cables and the sink cables are wound in pairs onto common shafts in such manner that winding up of the sink cables causes unwinding of the anchor cables, and vice versa. The shafts are, by a motion transfer arrangement, connected with each other and with an automatic locking device which allows vertical adjustment of the bridge due to changes in the water level, but which locks against vertical adjustment due to wave action or the bridge being loaded.

Abstract: A jack-up rig includes a cantilever beam assembly and a drilling module is mounted on the cantilever beam assembly. The jack-up rig also includes means for moving the cantilever beam assembly from the storage position to extended positions wherein a rearward end of the cantilever beam assembly is extended from the jack-up rig. The fixed platform comprises a fixed platform support structure having a drilling module support surface and a beam opening. The jack-up rig is positioned near the fixed platform with the cantilever beam assembly generally aligned with the beam opening in the fixed platform support structure. The cantilever beam assembly then is extended through a portion of the beam opening to an extended position wherein the drilling module is supported on the cantilever beam assembly a distance generally above the drilling module support surface. The jack-up rig then is lowered to a position wherein the drilling module is supported on the fixed platform support structure.

Abstract: A port ramp for access to a ship, having a first end supported by a quay and a second end rigidly supported by a float, the float being anchored by blocks to the bottom by a connection of selectively adjustable length, the maximum buoyancy of the float being at least equal to the weight of the ramp added to the maximum load thereon, so that, when the float is submerged, the height of the ramp above the surface is independent of the load on the ramp.
