Perry PC 1805 submers

Listing description

The SPDB is built by Perry and is classified by Lloyds Register of Shipping.

The pressure hull is constructed by low temperature service steel, with internal ribs and a internal diameter of 1.372 m.

The battery pods are pressure sealed, cylindrical and have a diameter of 0,50 m. they are equipped with removable ends, for easy entrance to the batteries.

The submersible is supplied with 1 entrance hatch in the tower and 3 entrance hatches for the diver lock out compartment (DLOC). Front of the pressure hull there is a spherical segment window of 0,89 m. Beside are 8 view ports of 0,20 m diameter equally spaced around the conning tower, an d 1 upward looking port in the top center of the hatch. All view ports are made of acrylic plastic.

The pressure hull is supplied by several blanked spares for additional equipment such as battery power, the use of high pressure air and for monitoring of the propulsion. All external equipment is protected by heavy-duty fender rails in case of a collision.

Crew

depending to its operation 2 or 3 crew with
2
divers
(DLO
mode)
or
3
passengers
(maximum 5 persons) Extra load

maximum 450kg

Buoyancy
4 external ballast tanks with a total capacity of 363L for the buoyancy
for the surface stability.

Trim
An internal variable ballast tank system is placed for compensation of
the weight change. The forward tank has a capacity of 91.5L, the after tank 228.5L with appropriate ballast pump.

Air
A
high
pressure
air
system
of
two
10,5cub/m,
200bar
cylinders
mounted
externally,
for
blowing the
ballast
tanks
and
as
built-in emergency breathing system.

Ventilation
In the SPDB is a constant 1 atmospheric environment with a constant
monitoring of CO2 and O2. Excess of CO2
will be out filtered with sodium carbonate (CO2 absorption chalk) by an electric powered scrubber unit, the
O2
will
be
supplied by 4
internal placed 50L oxygen cylinders.

Hydraulics
In the SPDB placed electric powered hydraulic pump supplies the
actuation/control of the stern rudder and diving rudder with 3 legs. The manipulators are controlled by an external placed system with its own pump.

Controls
At
the
pilot
seat
is a portable control box
with joystick, for the
controlling of the propelled and positioning thrusters. The pilot has the control over all the instruments which are needed for the power supply and the monitoring, in both normal as emergency situations.

Standard equipment

Navigation: compass, sonar, echo sounder, tracking transponder and depth gauges.

Communication: Mesotech underwater telephones (27 kz), FM radio for the surface use and diving communication system through the umbilical.

External lightning: 4 x 100 watt Quartz halogen lamps.

Cameras: 5 cameras with DVD recorder of which 4 fixed and 1 adjustable zoom and focus. The cameras will be used for monitoring and observation of the SPDB, the adjustable camera can also be used for underwater video inspections.

Manipulator:
2
hydraulic
controlled
multifunctional
34kg
WLP manipulators with 4 degrees of free movement and 5 functions. Transport: Special designed transport flat-rack with cover.

Safety features
In case of emergency the battery pods can be ejected te get extra
buoyancy.
In the battery pods a water sensor can detect eventual leaks.
Built in emergency breathing system (BIBS) with masks and life vests.
3 fire extinguishers of which 1 hyperbaric (in DLOC) Battery powered stroboscope as beacon.

Spare parts
With the SPDB comes a 10ft container with some spare and original
parts, like a spare spherical doom and thruster motors. When required a spare part list can be send separately.

Important note

At this moment the SPDB is not approved anymore and needs a new approval before its operational again.
Its situated in the Netherlands and can be visited any time on request.
