The Taiei Maru

 

The Japanese fleet oiler Taiei Maru...

A.K.A.

Okikawa Maru

 



The jury is out on the name of this ship... some people would have you call her the Taiei Maru, others the Okikawa Maru, others still have even called her Olympia Maru! We were introduced to her as the Taiei on our first dive and even though we can never spell it in our logbooks without recourse to a bottle of Tippex from time to time we're sticking with that name for now at least!

The Taiei Maru appears to be, quite apart from an invitation to keep adding E's to the end of her name, a Japanese "oiler" - that is to say a ship which carried heavy grade oil to re-fuel other ships at sea. But in addition it appears she also carried several different grades of oil to run a variety of machinery and vehicles  including very light grade fuels such as diesel and petrol. Most of her tanks are vast open caverns but there is at least one much smaller tank I have entered where there are baffle plates fitted inside. This presumably indicates that the tank in question was designed for a much lighter grade of fuel which would slosh around in heavy seas... hence the requirement to damp down the fuel's movement.  Unlike a true oil tanker she has quite extensive areas on the upper decks immediately below the bridge area which are turned over to duties other than the carriage of oil, along with crew quarters which take a considerable time to swim right around. This would seem to indicate to me that she carried far more crew than a ship designed just to get oil from A to B - I would take the additional accommodation spaces to mean that the crew were far greater in number and hence they had far more to do at sea than just sit round watching the oil slosh and the world go by - Q.E.D? Additionally some of the none oil carrying areas on the upper decks above the tanks, especially amidships, may possibly have been workshops or storage space for spare parts, ammunition perhaps, workshop areas, possibly even extensive sick bay quarters. It is hard to be certain about anything because post-war salvage may have robbed such workshop areas of tell-tale machinery.

I am most keen to learn much more about this enigmatic ship and her design philosophy!

The USS Lexington...The bow of the wreck is almost completely detached from the body where the heavy bombing she suffered broke her in two though her upper decks remain remarkably intact even after so many years under water. As with the other Coron Bay wrecks the Taiei Maru was attacked on September 29th. 1944 by American aircraft from AG's (Air Group) 18, 19 and 31, many of which were flown off from carriers like the USS Lexington seen here on the right.

The wreck is now home to many, many species of fish and is encrusted with coral growth however inside she is relatively clean of organic matter apart from occasional colonies of large crayfish which run up and down the inside walls of the tanks in the darkness. These creatures are quite bizarre and emit a high pitch screech if you disturb them - we think of aliens beings from outer space but in reality we have much weirder things here on earth beneath the waves inhabiting inner space!

VITAL STATISTICS:

168 m long - the biggest of the Coron wrecks in volume.

Max depth: 26 meters to seabed, 10 to 16 meters on the deck.

Penetration is very much the order of the day on the Taiei Maru. It is perfectly possible and highly exciting to enter the wreck through the propeller shaft and swim into the engine room then continue almost all the way back to the bows without ever leaving the wreck. The decks are quite magnificent in terms of wild life however there is almost always a strong current running and so swimming inside is desirable. Long dives are possible due to the shallower depths. Tracy completed her 20 metre mask clear for her BSAC Advanced Diver qualification whilst kneeling inside the bow wreckage and was rather shocked to see a large lionfish bimbling by when she had cleared the water out again!

Our January 2007 visit...



Our guide Tan Tan about to enter the wreck...

Taiei Maru was an oil tanker and within the wreck there is a lot of pipework blown to smithereens by American bombs in the attack...

A bomb penetration hole in the deck plating...

Tracy drops down through a bomb rent in the Taiei Maru's deck...

More interesting pipe work below decks...

Looking out through an opening in the tanker's hull...

Yet more damaged pipe work - only a wreck head can get excited about this!

A broken down bulkhead, the pipe entry hole clear to see...

Wheels and pipes... sorreeeee... I'm a wreck head!

Looking up from within the wreck towards the surface 20 metres above...

Mike swims over Martin's head as he takes the picture...

Mike inspects a railing dividing two sections of Taiei Maru's interior...

Lieutenant Latex behind bars!

Tracy had these two tiny fish swim with her for practically the entire dive!

Tan Tan leads us out of the wreck onto the decks...

Waiting for Martin to come out next!

Hard and soft corals and marine vegetation grow around a hatch way into the ship...

Tracy on a swim through concentrating on the movie camera's viewfinder...

A very large Lionfish - large and very poisonous but incredibly docile!

Fish swimming amongst the ruined metalwork...

Our guide swims us across the deck looking for our next point of entry...

Some sort of anemone? I've never seen anything like this before...

Small Anemone fish, large anemone!

And again! That's a lot of anemone to protect from intruders but he's up for it!

Large plate corals cover the superstructure softening the man made lines...

Mike Holroyd swims across the top of the wreck...

Another point of entry...

This coral head reminds me of a giant hamburger bun!

Parrot fish inhabit the deck towards the stern and turn the coral there into fine white sand...

A large Batfish lurks beneath the superstructure...

Tan Tan...

Shoals of tiny fish inhabit the vegetation on the wreck...
