A high-speed transportation system includes at least one transportation structure having at least one track, at least one capsule configured for travel through the at least one structure between a plurality of stations, a propulsion system adapted to propel the at least one capsule through the structure, and a levitation system adapted to levitate the capsule within the structure. At least one track is positioned to provide balancing force vectors to achieve stability for the capsule.

An apparatus, system, and method of loading of a compartmented dry-bulk-cargo barge in an efficient, safe, load-balanced, and environmentally responsible way, minimizing exposure to the elements, spillage, and spread of dust particles from the dry-bulk materials, through existing small hatch openings in barge compartment covers, without removing barge compartment covers, using an articulated arrangement of connected conveyers with rotating and telescoping capabilities, providing rapid change of position and precise positioning with minimal movement of the compartmented dry-hulk-cargo barge.

A cable handling bow (2) for an overboarding system of a work platform has a cable retaining structure (4) for retaining a length of a cable, where the cable retaining structure (4) extends along a partially curved path (6). The path (6) has a first end (8) and an opposed second end (10), where the path (6) has a first straight segment (14) located between the first end (8) and the second end (10) and is spaced away from both ends (8, 10), such that a cable joint connecting two ends of a cable is placeable in the first straight segment (14), when the cable length is retained in the cable retaining structure (4).

An arrangement for positioning a fall pipe end (414) during subsea rock installation includes a submersible frame (400) adapted to be lowered towards an underwater structure. The submersible frame has a first (401) frame structure carrying propulsion equipment (415) and a second frame structure (402) carrying survey equipment (406, 407), a channel structure (410), and a rotation system with an actuator (403). The actuator (403) has a first (411) and a second element (412) and being adapted to convert an energy input into a rotation of the second element (412) when holding the first element (411). The second element (412) is connected to the second frame structure (402), such that in suspended condition of the submersible frame (400), the survey equipment (406, 407) can be rotated about a vertical axis (409) by energizing the actuator (403), without using the propulsion equipment (415).
