Production From Thai Field FPSO
Commences
Rutherford-Moran Oil Corp., an independent energy
company which concentrates its activities in
Southeast Asia, announced that production from its
Tantawan Field has begun. The natural gas and
crude oil production from the two wellhead platforms
is being moved to FPSO Tantawan Explorer in the
field. The natural gas travels from the producing
wells to the FPSO and after further processing is
exported and sold to the Petroleum Authority of
Thailand (PTT). The crude oil is processed and stored
on the FPSO where it is periodically offloaded into
shuttle tankers and sold. The Tantawan Field is
reportedly the first field in the Gulf of Thailand that
produces crude oil and condensate as well as natural
gas. Tantawan Explorer began accepting production
on January 28 and initiated shipments of gas to the
pipeline three days later. Rutherford-Moran Oil,
through its Thai Romo Ltd. subsidiary, owns a 46.3
percent interest in the Tantawan Field. A subsidiary
of Pogo Producing Company owns a similar percent-
age, and the remaining interest owned by a sub-
sidiary of The Sophonpanich Co., Ltd.
Transocean Offshore Awarded $ 124 M
Drilling Contract
Transocean Offshore Inc. announced that it has
been awarded a three-well, turn-key, $124 million
drilling project by Petroleos Mexicanos (Pemex), the
national oil company of Mexico. The project was
expected to commence by late February, with an esti-
mated duration of two years, including well testing
services.
The three-well program includes two delineation
wells and one wildcat well, each located in up to 600
fsw in the Bay of Campeche. The wells will be drilled
by Discoverer 511, a turret-moored drillship owned by
Ghana National Petroleum Corporation (GNPC) and
bareboat chartered by Transocean Offshore.
The rig was scheduled to be in a Gulf Coast yard
undergoing a short refurbishment and upgrade pro-
gram in February, which was expected to be complet-
ed by mid-month. Upgrade and refurbishment costs
incurred on Discoverer 511 will be shared by
Transocean Offshore and GNPC, with Transocean
Offshore primarily responsible for the installation of
an existing top drive system and shipyard supervi-
sion.
Amoco And Shell To Develop $500 M
Deepwater Project In Gulf Of Mexico
Amoco and Shell Deepwater Development Inc.
announced plans to develop a $500 million deepwater
Gulf of Mexico oil and natural gas discovery located in
waters 328 ft. (100 m) deep to the south of Mobile,
Ala. The project will utilize a TLP and is expected to
produce 250 million cu. ft. of gas and 40,000 bpd of oil,
beginning in mid-1999. Dubbed the Marlin prospect,
the discovery was drilled in 1993 and is located on
Viosca Knoll Block 915 in 3,240 fsw. Amoco is the
operator and has a 75 percent interest in the field,
and Shell owns the remaining interest.

Mobile Docking Aid System for
Ships
Laser Communications, Inc. (LCI),
the marine division of Laser
Technology, Inc. (LTI), has intro-
duced a mobile laser docking aid sys-
tem with almost all the features of a
full-blown, fixed-base laser system.
Many of the same ideas and concepts
used on the NASA space shuttle pro-
ject were employed in the develop-
ment of the Rover mobile docking
system. The Rover is built around an
electrical, self-powered mobile chas-
sis.
The onboard rechargeable batteries
provide power to move and relocate
the entire docking system at
respectable speeds (about 20 kph).
The batteries also power the onboard
computer, display sign and transmit-
ter. The Rover is driven to a location
estimated to be approximately amid-
ships of the incoming ship. The dock-
ing aid system is then activated and
left to operate, unmanned.
When the incoming ship comes into
view, the Rover measures the closing
speeds and distances and records the
data on the computer for future ref-
erence. The pilot and captain can
observe the closing distances and
speeds on a display located on the
Rover.
As an option, the closing speeds
and distances can be relayed to
pager-type, handheld receivers on
the bridge of the ship and on the
dock. Utilizing the latest in commu-
nications technology, the docking
data can be sent anywhere in the
world, if desired. The main purpose
of the system is to provide the pilot with fast, accurate, usable information to help
maneuver the ship for a safe, expedient landing without fender damage.
The data generated by the Rover can also be used for training purposes. The data
will also be of use to dock owners in situations that warrant investigations of fend-
er damage.
Some ports experience extreme tides, currents and traffic that expose a moored
ship to drift-off. Also, as the tides change and the vessel is offloaded, the mooring
lines can slacken and expose the ship to drift-off. During the high risk periods, the
Rover can be used to monitor the ship for drift-off after it has been moored. The
mobility of the Rover allows the docking aid system to be used at several different
docks during the day and night. The Rover can also be configured to protect the
operator and system from the environment. While waiting for the next landing, the
Rover can be recharging its batteries back at the main office.
