1. Several offshore installation methods can be envisaged, depending on the pipeline characteristics (diameter, length, waterdepth) and the availability of suitable equipment: conventional pipelaying (S-curve), reeling, towing following assembly onshore (on-bottom, off-botom, mid-depth and surface), J-laying.
2. Conventional pipeline barges should have sufficient tensioner capacity to allow one tensioner to be kept on standby.
3. Stingers should not be longer than 60 metres.
4. Equipment shold be tested on mobilisation should include as a minimum the anchor wincher, the pipe tensioners, the abandonment and recovery winches, the pipe straighteners and all navigation/positioning equipment as applicable.
