Almarin was established in 2004 in Barcelona with
the objective of developing aids to navigation in Spain.
Backed by its Portuguese partners, Almarin made in-
roads into the Spanish market through innovation and
excellence in customer service. Simultaneously, the dis-
tribution of boatyard, port and harbour equipment was
successfully developed.
Almarin designs and manufactures buoys and beacons
and has a close collaboration with the leading manufac-
turers of lights and other equipment with which its buoys
and beacons are equipped. To strengthen its position,
in 2007 Almarin acquired Balizamar, founded in 1981,
and in 2008 Almarin became an industrial member of
IALA.
Based in Barcelona and competitively manufacturing
high quality products in Europe, the success of its na-
vigation buoys encouraged the continual development
and investment in the aids to navigation business area.
This success led to the internationalization of its activity
which began in 2012, initially focusing efforts in the La-
tin American markets.
Today Almarin is a specialist manufacturer of aids to
navigation with an increasingly global scope.

The Grupo Lindley of companies began its acti-
vities in 1930 with the establishment of Ahlers Lindley,
Lda. as a distributor of port and industrial equipment in
Portugal.
Today the group comprises of four companies, three of
which continue to focus on the original business activity:
Ahlers Lindley is a manufacturer of harbour and marina
equipment; Almovi distributes and services cargo han-
dling equipment in the industrial and harbour markets;
Almarin is a manufacturer and distributor of aids to na-
vigation.
Ahlers Lindley and Almarin pool engineering and produc-
tion capabilities sharing expertise in the design and ma-
nufacture of fixed and floating structures for the marine
environment. Almovi is a market leader in industrial and
port handling equipment with highly trained technicians
that maintain equipment in the most demanding condi-
tions.
Each company employs qualified staff capable of provi-
ding service to customers wherever it may be required.
The Grupo Lindley companies are proud to be conside-
red a benchmark by customers who have acquired its
products and services.

Balizamar
Navigation
Buoys

Aids to Navigation
Balizamar buoys are designed and
manufactured in accordance with
IALA recommendations; this range
is suited to most marine beaconing
needs. Years of experience combi-
ned with the best engineering and
a careful selection of materials pro-
vide a range of high performance
buoys at an affordable price.
All Balizamar buoys are characteri-
sed for having a unique galvanized
steel structure that passes through
the hull transmiting the loads
through a large circular plate onto
the hull. No joints or screws to hold
the plastic components together.
Balizamar buoy hulls are made of
rotomoulded polyethylene and filled
with expanded polystyrene foam,
which ensures flotation in case of
a breached skin. Its steel structure
supports the mooring and tower
evenly distributing loads on the up-
per surface of the hull.

The GUIA range is the top, most ro-
bust range of buoys manufactured
by Almarin. They are designed to be
used in marine navigation where na-
tural conditions are demanding, the-
re are high volumes of marine traffic
or for situations that require using
the most rugged product available.
The hull of the GUIA buoys is ma-
nufactured using closed cell po-
lyethylene foam core, which makes
them virtually unsinkable. The core
is covered by a polyurethane elasto-
mer skin, which makes the assembly
flexible and resistant to impacts they
may receive from marine traffic.
The load bearing structure, usually
a tail, transmits the loads from the
mooring to the hull and is manufac-
tured from hot dipped galvanized
steel.
The GUIA buoys are tailor-made,
with a modular type build and avai-
lable in multiple sizes and shapes.

The A800 model is an economical
and single body buoy manufactu-
red from rotomoulded polyethylene
and available in several shapes and
colours. This product is the most
commonly used for the beaconing
of beaches but can also be used for
the provisional beaconing of marine
works, dredging, small channels and
temporary installations.
The buoys can be purchased empty
or full of polyurethane foam, which
ensures the buoy will remain afloat
even when the hull has been brea-
ched. In very shallow waters, the
buoy can be equipped with ballast
to ensure its stability. The A800 was
designed as a blind buoy but as an
option small lanterns and/or top
marks (only in the case of the cylin-
drical buoy) may be installed when
used in very calm waters.
Options: self contained lantern top
mark on the cylindrical buoy and fi-
lled with polyethylene and/or polyu-
rethane foam and ballast material.

Almarin’s engineers will assist in selecting the correct
product and mooring for each application. Almarin offers
turnkey supply and installation if required
• Breaking areas
• Areas with very strong surf
Spar buoys are recommended for
use where there are breaking seas.
Manufactured in the shape of a tor-
pedo and with reduced reserve buo-
yancy, the buoy will submerge and
sink under breaking conditions, offe-
ring a low resistance and a minimum
pull on the mooring.
The buoys are manufactured in glass
reinforced polyester and their inter-
nal chamber is partially filled with
closed cell polyethylene foam to
prevent it from sinking in case of a
breached hull.
Almarin manufactures two models:
3m and 6m. The selected model will
depend on the depth of the loca-
tion where they are to be installed.
In both cases a minimum depth is
required (which will depend on the
swell) to ensure the buoy does not
touch the bottom. The installation of
this type of buoy will require a de-
tailed study of the depths where it
is going to operate, since its reserve
buoyancy is limited and the design
of the mooring is critical for correct
operation.

Recommendation of using the proper buoy for each appli-
cation and mooring calculation
• Narrow channels, inside of ports
• Marking of dredging limits
• Exterior seawall limits
• Turning basins
• Seawalls or submerged obstacles
Articulated navigation buoys have a
reduced swing radius. These buoys
are recommended for applica-
tions that require a highly accurate
beacon placement and are typically
found in narrow channels or inside
the port itself, usually marking the
limits of turning basins. These buoys
are frequently used for marking the
bases of quaysides or moles where
there is an abrupt change in depth.
Each buoy is comprised of a tube
that extends from a universal joint
attached to the sinker to the lamp
located at the top. A hull that is lo-
cated a few metres below the surfa-
ce applies a constant upward force,
which maintains the assembly in a
vertical position.
This type of buoy requires a detai-
led study of the location and will
not perform correctly in applications
with strong currents or where the
variation in water level is high (due
to the tide or wave height). The stan-
dard operating depth is between 12
and 60m.

re below is located at the north en-
trance to the Port of Barcelona.

PORT BEACONING
ALT posts are used as aids to na-
vigation in and around ports and
harbours. Not only do they support
a lantern for night time beaconing,
they also act as a day mark.
The posts are built from stainless or
in hot dip galvanized steel painted in
accordance with IALA recommenda-
tions. The final result is a very strong,
weather resistant structure that can
be tailored to the customer’s requi-
rements.
The ALT 3 posts are primarily used
for beaconing inside ports and har-
bours. They have been designed to
work with self contained lanterns.

The quality control of manufactured products is a
priority at Almarin. The company strictly monitors
the quality of its workmanship and raw materials
used. Traceability is of the utmost importance so as
to be able to assess performance throughout the
life span of the product. Almarin is ISO 9001:2008
and ISO 14001:2004 certified, which shows its
commitment to quality and the environment. Re-
gular internal meetings monitor and standardize
activities and promote a constant improvement of
the company’s products.
Almarin has been a member of the International
Association of Lighthouse Accessories (IALA) since
2008. IALA provides guidelines and recomenda-
tions for the design of aids to navigation; Almarin
incorporates the majority of the association’s re-
commendations into the design of its products.
Almarin benefits from the Lindley
Group’s know-how acquired over 85
years of experience manufacturing
products for the marine and port
environment. The added value is re-
flected in the design and control of
solutions for their customers.
The standard, batch produced pro-
ducts are periodically reviewed for
updating of designs and procedures.
Almarin is continuously analysing
materials, ensuring that the most
suitable materials are used for each
application. Prior to adopting new
designs or incorporating new mate-
rials, the solutions are tested using a
variety of alternative methods: phy-
sical tests conducted at our installa-
tions or in the marine environment
and materials testing in external la-
boratories.
All the new designs are created using
three-dimensional tools and a sub-
sequent structural analysis. The use
of state of the art tools and the de-
dication of qualified personnel in the
Lindley Group are the foundation for
high quality products manufactured
by Almarin.
