Is this the Hospital Ship that is preserved in Yokohama? I visited it often in the 70's and 80's when ahore before being distracted by "other seafarers interests". Good photo.

Hi jabegren
The two main diesel engines for the HIKAWA MARU were built 1929 by Burmeister & Wain, Copenhagen.
The type 8680DS160 was 4 stroke dubble acting 8 cylinders with 5500 bhp each. They had the engine numbers 1602 and 1603.

There is no such thing as a double acting 4-stroke.
This is a single acting 4-stroke.

The double acting B&W and later H&W engines were double acting four strokes such as the figure on page xviii of CC Pounder 8th. Edition, installed in the 1925 Gripsholm. The H&W engines were virtually standard in Blue Funnel's post WW2 fleet regeneration. The engine is comparable with the Doxford design. With the Super P's, single acting 2-S became the standard engine (Sulzer and B&W).

Sailed on Lamport and Holt D boats (Debrett, Devis and Delius.
Worked on Blue Funnel Motor Ships.
Checked C.C. Pounder's Book.
All double acting 2-strokes.

The HIKAWA MARU engines are of the same type as the ones in GRIPSHOLM and KUNGSHOLM although smaller bore. According to a book: "B&W-dieselmotorens historie" (publish by MAN Diesel) from 2008 these engines are 4 stroke dubble acting diesels. However only 6 ships were equipped with this type (from Burmeister & Wain, Copenhagen), apart from the already mentioned: CHICHIBU MARU, HIYE MARU and HEIAN MARU. The engines were of B&W-design not Doxford.

Hi Bob,

I, like you, was a little sceptical. This is what made me check CC Pounder. The engine that they mention was a B&W 840-D four-stroke, double acting engine installed in the Swedish America Line's "Gripsholm" of 1925, the first transatlantic motor liner. Based on the transverse section shown in CC P, This engine appears to be of similar configuration with the non-vertical pushrod arrangement. A bit of a mystery! According to Pounder, shortly after, the 2-S double acting engine became very popular, very closely followed by the introduction of the "standard" (same basic design until 1968!) Sulzer 2-S engines which had a very high (compared to earlier engines) cylinder power. Sulzer's impetus appears to have been the engining of several NZ Steamship vessels which required high power and service speeds, mostly triple screw arrangements.

Regards,
Dave

The engines fitted to the S.A. Lines were indeed double acting 4 cycle engine as is the above, this design started its life as a single cylinder test engine at the experimental test station at Christianshavn and was the subject of two years work which included 4 months of continuous running without any stops at all. The design was considered to be a very important step for B&W. The engine could also be built as a long stroke engine for single screw vessels.
