Helge August Olsen Myhre voyage to London

So now with a reasonable indication of documents showing vaccination date and documentation for 'leaving a Parish' dated August 1851 in Stavanger, we now seek vessel details for Helge August Olsen Myhre to U.K around this time. I have not been able to see anything so far. The next appearance we have confirmation of, is his marriage to Emily Brunette in London in July 1859. They had two children, he died in 1864, by this time it seems using the christian name of Albert August Myhre. He appears in the London Gazette 21st February 1862 as Helge August Myhre as having developed an invention of 'improvement in ships logs' with his profession listed as 'watchmaker'. So the period of leaving Norway could be from September 1851 to I would guess 1853. We have been provided with a record of a Myhre on the SS Courier to Hull 1857 but I feel this is too long from the dates above to very close to his marriage date.
