Material selection for hydrocarbon and sea water systems is shortly described and experiences are explained. The risk of external stress corrosion cracking is discussed. Same is the need for isolation pipe spools to avoid galvanic corrosion.

Possible corrosion as result of hot work reduction on platform modification work is discussed. Benefit from positive material identification is explained and the solution of a weld problem due to mix-up of filler material is shown.

Experiences with cold bending and subsea material engineering are discussed and recommendations are given.

Fracture mechanic techniques with purpose of avoiding costly replacement and repair welding are shown by two examples. At the end the new cost reduction trend of using performance based specifications is shortly discussed with respect to material requirements.
