Types of Plataform

Get to know the technologies we use in our operations at sea.

Platforms can be for drilling, production (when it can lift the oil and separate oil, water and gas) or have both functions. In each field, we analyze the conditions to determine the most appropriate type of platform. On a platform, we can find engineers, technicians of various specialties, hoteliers and nurses, safety specialists, and divers, among others. In Brazil, we work with over a hundred production platforms, most of which fixed.

Select the platform that you want to know:

P-55 semi-submersible platform operating in the Roncador field,
in the Campos Basin. Weighing in at 52,000 tonnes,
and with an area of 10000 sqm, the P-55 is the largest
semi-submersible built in Brazil, and one of the largest in the world.

Floating unit that can
PRODUCE, STORE AND OFFLOAD OIL.
The oil is drained by SHUTTLE VESSELS
and the gas flows through pipelines.
Has GREAT MOBILITY
and is primarily used in the most
isolated places, with little structure
available to deploy a fixed platform.
Important for production in
DEEP AND ULTRA-DEEP WATERS.

FPSO Platform
TYPE OF PLATAFORM FPSO
WATER DEPTH (DEPTH AT THE INSTALLATION/OPERATION SITE). More than 2,000 meters (it can be installed at great depths thanks to modern anchoring systems).
HOW IT IS Floating platform, in most cases converted from oil tankers. As is the case with the semi-submersible platform, it is anchored to the seabed.
DRILLING ACTIVITY No.
PRODUCTION ACTIVITY Yes.
WHERE ALL CONTROL TAKES PLACE Seabed.
STORAGE CAPACITY Yes.
PRODUCTION FLOW The oil is offloaded to tankers, which, in turn, offload it at the terminals.
ADVANTAGE The storage capacity allows them to operate at great distances from the coast, where building pipelines is not feasible.

It is an FPSO, but with a

ROUND HULL,
which affords
greater stability.
The first platform with
these characteristics in
the world is the one we
have been using in
PIRANEMA, SERGIPE,
since 2007.
We are developing the Mono-BR,
which we will be able to use in
ULTRA-DEEPWATER
and harsh environmental conditions.
Its stability is further
increased thanks to an
opening in the central
portion, which allows for the

ENTRY OF WATER
and reduces the movement caused by the waves.

PRODUCTION.
It is known as
"FLOATING, ALMOST FIXED"
because it is a floating unit,
but has an anchoring system
that uses tendons (or legs) fixed
by piles driven into the seabed.
Thus, as is the case of the
fixed platform, well control can
be done from the
SURFACE.
The first TLWP of Brazil (the P-61) is
installed at the PAPATERRA FIELD
(Campos Basin).
The P-61 is moored by
EIGHT 32 INCH
TENSION LEGS

spiked by 80-meter long piles.
The TLWP has great potential
for use in production at the
PRE-SALT
