SB-2200P Sentinel®, a larger patented version of the extremely successful SB-98P, is Tideland Signal’s newest generation of large sea buoys. This buoy’s patented hull, lifting and mooring eye system, and its twin-keel design, bring together two decades of experience in providing worldwide, on-station alternatives to steel and GRP buoys. The SB-2200P modular design is ideal for use in open seas, exposed channels and harbours, and its twin keel provides superior performance in currents up to 6 knots. SB-2200P is a direct replacement for most steel ocean buoys.

Diameter:  2.2m


UV-Stabilised Polyethylene
Rotationally moulded for a tough 12mm thick body with increased thickness for reinforcement at stress points. The polyethylene material is abrasion resistant, shock absorbing, impact resistant, and able to withstand collisions at sea. In addition, it repels marine growth. Colour pigment is impregnated throughout, eliminating the need for repeated, costly sandblasting and painting.

Modular Construction
A float section, middle superstructure section and top navaid section form the SB-2200P buoy. In the event of damage, individual sections can be easily replaced on the deck of a buoy tender at sea.

Matching or Alternating Colours
Bifurcation buoys easily can be made, either red or green as needed. Cardinal buoys can be assembled using the same method with yellow and black sections. Fairway or Safe Water buoys are produced using a process of colour graphics, resulting in red and white vertical striping. Wreck marker buoys use the same process, resulting in blue and yellow vertical striping.

Float Section of 2.2 Metres Diameter
Utilises a patented high strength, internal structure, solidly linking a two-position mooring eye, two lifting eyes, deck and superstructure. The hull is filled with polystyrene beads, expanded and bonded through a steam process, filling voids and limiting water ingress in case of puncture. The one-piece polystyrene adds rigidity and support to the tough polyethylene outer hull. Twin keels provide stability in fast water and support the buoy standing erect on deck. The SB-2200P two-position mooring eye is provided for either fast or slow water conditions.

Superstructure Section
A maximum of four (4) 12-volt, 105 Ah lead-acid batteries can be located within this section above the waterline. This section includes a hinged, tamperproof, watertight service hatch.

NAVAID Top Section
This section supports up to four (4) optional 40-watt solar modules. Configurations can vary depending on electrical load and average solar insolation for the deployment site. An internal, high gain, passive radar reflector (10m2) can be included. All additional internal optional equipment is housed in this section.

Crating / Shipping
The design of the SB-2200P allows transport of four (4) buoys in a standard 40 foot container, minimising shipping costs.

The standard SB-2200P is suitable for use with a self-contained lantern.
