the weather or the sea state and are less expensive than seaborne operations. Pipeline supply can be coordinated: while one line is being laid at sea, another one can be spooled onshore. A single reel can have enough capacity for a full length flow line. The reel-lay system, however, can only handle lower diameter pipelines – up to about 400 mm (16 in). Also, the kind of steel making up the pipes must be able to undergo the required amount of plastic deformation as it is bent to proper curvature (by a spiral J-tube) when reeled around the drum, and straightened back (by a straightener) during the layout operations at the installation site.

Challenges with this type of system include: requirement for an abrasion-resistant coating, interaction with other submarine pipelines and potential obstructions (reef, boulders, etc.). Bottom tow is commonly used for river crossings and crossings between shores.

A particularly long stinger could be used, but this is also objectionable since that structure would be adversely affected by winds and currents. The J-lay system, one of the latest generations of lay-barge, is better suited for deep water environments. In this system, the pipeline leaves the vessel on a nearly vertical ramp (or tower). There is no overbend – only a sagbend of

245:: If and where the proposed pipeline intersects an existing one, which is not uncommon, a bridging structure may be required at that juncture in order to cross it. This has to be done at a right angle. The juncture should be carefully designed so as to avoid interferences between the two structures either by direct physical contact or due to hydrodynamic effects.
402:: In this configuration, the pipeline remains at the surface of the water during tow, and is then sunk into position at lay site. The line has to be buoyant – this can be done with individual buoyancy units attached to it. Surface tows are not appropriate for rough seas and are vulnerable to lateral currents.

193:: High currents are objectionable in that they hinder pipe laying operations. For instance, in shallow seas tidal currents may be quite strong in a strait between two islands. Under these circumstances, it may be preferable to bring the pipe elsewhere, even if this alternative route ends up being longer.
539:
In areas where the water is very deep, the S-lay system may not be appropriate because the pipeline leaves the stinger to go almost straight down. To avoid sharp bending at the end of it and to mitigate excessive sag bending, the tension in the pipeline would have to be high. Doing so would interfere

Pipeline construction involves two procedures: assembling many pipe segments into a full line, and installing that line along the desired route. Several systems can be used – for a submarine pipeline, the choice in favor of any one of them is based on the following factors: physical and environmental

Submarine pipelines generally vary in diameter from 3 inches (76 mm) for gas lines, to 72 inches (1,800 mm) for high capacity lines. Wall thicknesses typically range from 10 millimetres (0.39 in) to 75 millimetres (3.0 in). The pipe can be designed for fluids at high temperature

Proper planning of a pipeline route has to factor in a wide range of human activities that make use of the seabed along the proposed route, or that are likely to do so in the future. They include the following:
