Built 1970 by Kawasaki, Japan.
6300 grt reefer powered by 10 cylinder MAN 2-stroke diesel of 12,600 bhp driving a controllable pitch propellor giving a speed of 20 knots.
She was third of eight generally sister ships by same builder. She had a somewhat chequered career - on maiden voyage from Japan developed serious cracking on main deck. She put into Hawaii for repairs and inspection revealed the need to order her two sister ships to port where as precautionary measure steel beams were welded to main deck lengthways from accommodation to forecastle until a permanant solution could be reached.
A second serious incident in her early life was lengine lub oil contamination that caused engine failure off the coast of Panama. In danger of grounding tug assistance was sought.
It has been said that the best view of a ship is through the rear window of a taxi as one heads for home. As far as this ship is concerned that is very true. Sold in 1982 and renamed Al Moshtaree, broken up India 1994.

I sailed one trip on her as third engineer in 1980. Joined her in Baltimore and left her in Genoa. She was a happy ship, a pig to bunker and we had numerous scavenge fires on the trips across the Atlantic.

Sorry to read of your scavenge fires. - She used to use a McGregor-Livanos engine cleaning system. A chemical could be injected into various parts of the scavenge spaces and turbo charger inlet. I thought it was a good chemical. I was not amused when the order came from Queensway that it was no longer going to be supplied, presumably on a cost basis. We did not get any scavenge fires and it prolonged the service life of the valves on the underpiston scavenge system - Nos 8, 9 and 10 cylinders if I remember correctly. - One could tell if these valves were working correctly when they sounded like a galloping horse ! How did you get on with air start valves - at least one could be guaranteed to stick open on each engine start. - I left Motagua in mid 1974 also at Genoa and was not sorry to go.

Hi Jim

Yes I had forgotten about the valves on the scavenge system if my memory serves me well they were a very dirty job to change. Yes the air start valves always sticking open perhaps due to the infrequent starts of the main engine. With a normal propellor the main engine would have had numerous starts on standby. When I joined the CPP took some getting use very strange having the main engine running and not moving.

Alan,
The CPP gave me some embarrassment one day - we were galloping along about 20 knots in calm seas when I got a call from the 3/E that a small bore pipe had blown off the CPP control unit mounted on the prop shaft and leaking hydraulic oil. Mindful of the air start valve problems I decided that if I shut down the CPP hydraulic pump the prop would fail to full ahead pitch - WRONG. I did hear some cavitation type noise from outside the hull as we plugged off the affected part, thought it strange but of no consequence. Restarted the hydraulaic pump and went to the bridge to let the 2nd Mate know the situation. - It transpired we had just overtaken an elderly Greek ship when I shut off the CPP pump. The prop went into Full Astern mode so we passed the same ship again this time going astern - Job was completed - pump restarted - Full Ahead pitch restored and we passed this by now very bemused Greek ship again for trhe third tiime. I had attended a one day Kamewa course and I thought the guy had said the prop would fail safe to full ahead pitch. Maybe I just dreamt it. The Mates just loved the CPP - but sometimes engine control had to be taken from them when they got too enthusiastic on "Full Away" - if applying too much power too quickly the two turbochargers would protest quite vocally.
Did you ever have the Engine Control Room Air Conditioning fail? - the very early design of data logger would object and print out the main engine exhaust temperatures as Dollars.
