A marine hose has a twist coefficient 1900K2900 of fiber cords constituting a fiber reinforced member with three or four twisted filaments made of polyester, an interrelationship R between a predetermined elongation ratio E2 of a plurality of types of the fiber cords having different specifications and a hose elongation ratio E1 in a predetermined expansion test of each of marine hoses in which the fiber reinforced member including the respective fiber cords as constituent members is embedded as reinforcing layers is determined in advance. A threshold Th of the ratio E2 is set based on a standard value of hose elongation ratio E1 in the predetermined expansion test and the interrelationship R and the predetermined elongation ratio E2 of the fiber cords used as the reinforcing layers is set to the threshold Th or less.

An underwater floating pipeline with the ability to self-maintain desired depth beneath the water giving the ability to connect distant locations. The sections maintain and alter buoyancy for repair and maintenance. Multi chambered pipes allow different rates of flow. Automatic snap-shut doors protect against leaks and loss of pressure. Warning systems alert those in proximity to the pipeline. Freight may use the tunnels to avoid adverse surface weather and high shipping cost and fuel and labour savings.

A buoyant stretchable hose assembly, and mooring systems utilizing same, adapted to be filled with a gas to change its buoyancy in water to create an upward curvature under calm conditions while providing sufficient scope during dynamic conditions to effectively moor a surface buoy or ship while minimizing damage to benthic communities.

A float system includes a first float element and a second float element. The first float element is attachable to the conduit, and the second float element is attachable to the conduit adjacent the first float element. The first float element and the second float element are capable of restricting a bending angle of the conduit.
