The 25 ft (8 m) Transportable Port Security Boat (TPSB): (AKA The Guardian) is a twin outboard motor, open deck, all weather, high performance, moderately-armed platform capable of operating in inner harbor/near shore environments in light sea conditions.
VB-10,000 is a heavy-lift twin-gantry catamaran consisting of two truss space frames atop two barges.The design was derived from Versabar's earlier VB-4000 (aka Bottom Feeder), [1] [2] which was developed to clear debris from toppled oil drilling platforms in the Gulf of Mexico.
The Arrowhead West Tunnel is 3.8 mi (6.1 km) long and 12 ft (3.7 m) in diameter. The tunnel begins at Devil's Canyon and is the first of the three tunnels in the feeder project. It continues east to the Waterman portal at Old Waterman Canyon Road and California State Route 18. The tunnel was constructed with a grade to allow water to flow by ...
Not shown is the rare, but also possible combination of a 30-foot container coupled to a 10-foot box, in a 40(+) foot long stack. The ISO 668 standard firstly classifies containers by their length in whole feet for their 'common names', despite all measurement units used being either metric (SI) or officially based on the metric system .
In Houston and East Texas, they are called feeders. Dallas and Fort Worth area residents call their frontage roads "service roads", and "access roads" is the predominant term used in San Antonio. [8] Most signs reference "Frontage Road" despite local regional vernacular (there are signs in Houston that use the term "feeder").
The 2 × 25 kV autotransformer system is a split-phase electric power system which supplies 25 kV power to the trains, but transmits power at 50 kV to reduce energy losses. It should not be confused with the 50 kV system. In this system, the current is mainly carried between the overhead line and a feeder transmission line instead of the rail.
One of the earliest and most critical tasks in a submarine pipeline planning exercise is the route selection. [5] This selection has to consider a variety of issues, some of a political nature, but most others dealing with geohazards, physical factors along the prospective route, and other uses of the seabed in the area considered.
[25] The father and son researchers Ramette and Ramette successfully siphoned carbon dioxide under air pressure in 2011 and concluded that molecular cohesion is not required for the operation of a siphon, but: "The basic explanation of siphon action is that, once the tube is filled, the flow is initiated by the greater pull of gravity on the ...
