As BigInch mentioned, you would better to tow them instead of laying.
and as you mentioned, several tie ins make it impractical.
but there is a technology named Snake lay technology provided by SLT International company can arrange it for you with 3 or 4 tie-ins. visit www.slt-international.com...
Hi guys,
Is application of automatic welding machine for offshore pipeline welding (on laybarge) enforces any requirement on pipeline dimensional tolerances?
Is DNV supplementary requirement D is mandatory or at least strongly recommended to be applied if automatic welding is going to be used?
