March 1953 - August 1991


This is a rundown of my time with ONI, and subsequent struggle to make a living and finance my hobby, biking:

After near 6 years in the Swedish Navy and 5 in the Merchant Marine I joined Offshore Raydist Inc, an ONI sister company, early March 1953 as a Raydist Mobile Operator. I worked on domestic operations in the Gulf of Mexico until early 1957, when I resigned, purchased a 1956 Ford pickup and drove from New Orleans to San Josť, Costa Rica. After a year there I joined ONI's foreign operations as a Shoran Mobile Operator, first in Venezuela and then in the Persian Gulf. This was followed by Italy, many Central and South American and African countries, Canada, and the Far East. Then came 4 years as an Area Supervisor in Singapore (1971 - 1974). In 1975 I worked in Brazil, before being transferred to the Geneva office to replace Fred Mueller. April 1977 saw me transferred to ONI's head office in Harahan, New Orleans.

After ONI's founder, Robert Suggs, died, and his much younger widow, Carroll Suggs, took over, things went down-hill, so I resigned in August 1991along with Joe DeLerno, who was then Company President. 

Since leaving ONI I have been involved in several businesses, Equipment Leasing, Real Estate, Restaurants, a Volumetric Concrete Delivery Company, and an ATM company. In other words: a Jack of many trades, but Master of none. The Real Estate, Restaurant and ATM are still active. And, of course, I have spent a good part of my "retirement" viewing the world from the saddle of a motorcycle - best estimate 500,000 miles so far.

Photos from Esso rig location, Bass Strait, Australia, 1965. I was here for over a year before going to Costa Rica to assist the high school graduation of my stepdaughter Patricia. Bill Cooper replaced me, and he stayed for a couple of years before going to China (?) to study acupuncture. Besides rig positioning I was in charge of Esso's supply yard and radio communications. I was the only ONI man on the job. Picked up base operators off the street when needed (sounds familiar!). I set the station, lined up the antenna, and asked them to keep the generator running.




Curtis Island, Bass Strait, Australia, July 1965. Site was only accessible

 by helicopter.


Helicopter flew equipment to the top of Curtis Island. Barely enough space to set down, no room to put up a tent until after the chopper left.


Electrotape - electronic measuring device. In use here at Merriman, Victoria, Jan 1965.

Wally Harmon, a temporary ONI hire, operated the Electrotape as required.


Helicopter perched on top of the Shoran site before the camp was set up. The guy's name is Ron, local, temp ONI operator.

to a point 73kilometers 

away on the Australian mainland.  Ron again.

airport, Venezuela, June 1958. Karl, ONI Technician/Engineer, Yugoslav, designed the Shoran pre-amplifier that was installed on top of the tower, next to the yaggis. He left ONI and moved to California, later 

dying of brain tumor complications.

 perhaps awaiting his turn on 

the hubble bubble!

The bike. Quite a cool piece of kit by 

appearances. No doubt about where 

in the world we are today.
