Hope that helps C# is case-sensitive. Your iteration variable is ship_id but you're trying to use Ship_Id in the loop.
Ideally, use C# naming conventions instead (and for other variables too):
code :
// Declared outside the method.
private const string InsertSql = 
    "insert into PROJECT_SHIP (CR_Number, Ship_Id) " +
    "VALUES (@CR_Number, @CCF_Number)";

...

string[] shipIds = ShipsInScope.Split('|');
foreach (string shipId in shipIds)
{
    using (SqlCommand command = new SqlCommand(InsertSql, connection))
    {
        command.Parameters.Add("@CR_Number", SqlDbType.NVarChar, 10)
                          .Value = crNumber; // Unclear what this means
        command.Parameters.Add("@Ship_Id", SqlDbType.NVarChar, 10)
                          .Value = shipId;
        command.ExecuteNonQuery();
    }
}

it should still fix some issue Is it possible to add another where clause on this, or do I need to make another foreach? , You can just put it in the same Where clause:
code :
foreach (Point point in _Points.Where(x => x.Name == "Test" && !x.Asset.StartsWith("INV"))
{

Hope this helps Why not simply check if the value is what you expect and then break out of the loop? Or am I not understanding something correctly?

it fixes the issue Updating shared mutable variables in a stream is frowned upon. This should do it.
code :
resultEmpty.stream().forEach(empty -> {
  resultWithValues.stream()
      .filter(
          withValues -> withValues.get("name").equals(empty.get("name")))
      .findFirst().ifPresent(withValues -> {
        empty.replace("totsuccess", withValues.get("totsuccess"));
        empty.replace("totfailed", withValues.get("totfailed"));
      });
});
