Nope. Or most probably not.
Depending on time of year especially, your equipment will go through heat/cool cycles and will breath in moisture laden and worse, salt laden air. If the temperatures are low enough, the metal parts will "sweat" internally as well as externally.
My biggest dread and the most damage I experienced when I shipped gearboxes from Europe (via Rotterdam) to the USA was when they were at sea during the coldest months. I have had some pretty rusty stuff show up - stuff that was oily when it left due to having been filled and drained.
Your choice is:
1. Roll the dice and do nothing and with crossed fingers hope that the residual oil will hang in there. It might, but...
2. Coat the internal parts with a preservative or rust preventative that you know will hang in there - probably not doable in a gear box.
3. Completely seal the gearbox so that there can be no possiblity of ingress of moisture/salt laden air. Probably easier said than done. And if doable, then beware of and allow for pressure differences internal to external due to temperature fluctuations.
4. Place dessicant bags in the crates, and wrap the gearboxes as well as possible with moisture proof cloth or paper. And if there is access to gearbox internals, place dessicant bags inside the gearbox with instructions for removal clearly posted on the equipment.
Method 4 was done for the most part with the large gearboxes I imported and it worked reasonably well. Method 2 was used for the individual parts, gears, shafts, pieces parts, etc.
When I had a choice, I tried to time the shipments so that they would be on the north Atlantic during the warmest weather. I had some bad cold weather experiences.
