Preservation and Storage
Subsea tensioners are made of Stainless Steel with an additional electrolysis nickel finish. They are corrosion and wear resistant and under suitable conditions will not rust.
Any tools which are exposed to salt water should be rinsed with fresh water and dried before storage.
Tools which have been exposed to water during usage (from rain or similar) should be throughly dried before storage. Once packed, all accessible surfaces of the tools should be sprayed with a suitable non-drying rust prohibitive oil (for example, Shell Ensis Fluid or Castrol Rustillo DW300X).This is to ensure that the tools remain rust through their service life.
During storage, it is recommended that all hydraulic fittings have their connected dust caps correctly fitted to prevent any foreign objects getting into the fittings and fouling them.
The packing crates that are provided as a standard are not water tight and should be covered (under a waterproof tarpaulin or plastic sheeting, for example) if used for longer term storage. The packing crates will protect against incidental splashes but are not designed for constant wet conditions.
Pack the tools into the crate with suitable packing material to prevent the tools from sliding around.
