Freshly released into the Oceanography equipment range is the Multiport DTS Drop Camera System. Capable of operating to 2000m water depth, this

deep water inspection tool operates over a single

coaxial sonar cable, utilizing the innovative digital

telemetry link to provide power and bi-directional

control to all subsea instrumentation. At the heart

of the system is the high resolution 14 Mega Pixel

Digital Subsea Camera which has a wide range of

adjustable parameters including ISO sensitivity, zoom

and resolution. The camera has been designed to

be user confi gured on the “fl y” via the PC graphical

user interface, which is Ethernet interfaced to the

topside Multiport DTS. Another signifi cant feature is the

ability to download and view captured images within

moments of exposure. This time saving feature provides

the user with the confi dence to move onto the next

location without having to recover the camera to

access the captured images. The system can also

accommodate external video overlay information

to display vessel specifi c information to each

capture. Further to enhance the underwater viewing

performance, selectable underwater LED lamps and

a high power fl ash module are accommodated onto

the custom seabed frame. Additionally a number

of sensors such as a velocity sensor, motion sensor

and altimeter can be installed and confi gured via

dedicated high speed RS232 and RS485 com ports.

Sonar Equipment Services have an extensive track record in providing deployment solutions for side scan sonar and sub-bottom systems in both shallow and full ocean depth applications. To continue the expansion of this division, SES has

invested in key deployment winches and power reels

to complement the existing range. The latest addition

is the 6000m Deep Tow Winch, fi tted with 11.4mm

single coaxial cable. The specifi cations include a fully

enclosed electro hydraulic drive system with variable

speed control via local and remote controls. This

confi guration demonstrates a versatile solution which

counters limited deck space and provides the user

greater winch control. In addition a precise cable

level wind system is fi tted to insure cable lay is optimum

for safe, reliable operation.

To support near-shore projects, SES has developed

the DC Powered Cable Reel to provide an economical

deployment solution, where larger winches are

either not required or not an option. The Power

Reel has been designed to tow side scan sonar or

magnetometer towfi sh, and have a proven record

in the Renewable Energy sector. Developed to be

operated on small boats, the generator friendly 24v

dc control system offers a variable speed motor for

greater control which is recommended when towing

expensive equipment close to the seabed fl oor. The

stainless steel construction is robust but lightweight

enough to be portable and to further aid fl exibility, a

series of reels can be confi gured for multi-deployment

operation via a single control panel interface, with the

ability to control the reels independently or collectively.

A design which is well suited to gradiometer surveys.

The SES Digital Sub Bottom Transmitter has been making a name for itself since its release 12 months ago. With advanced software driven

features, the Digital Transmitter demonstrates a high

performance approach to sub-bottom profi ling.

All of the functionality expected in a transmitter is

provided but with extra features that give signifi cant

improvements in performance. Firstly a carefully

developed front end receiver offers unparalleled

shallow water performance. The option to transmit

and receive on dual transducers has been kept,

however this reduced power option is no longer

required as clear signal imagery within a metre is

achievable in both combined and separate mode.

Deep water applications have also been catered

for by a reliable solid state 20kW power supply that

has a 3 KHz to 15 KHz variable pulse length frequency

range. An optional heave input from industry standard

motion reference sensor further improves deep water

operation. Automatic impedance matching has

been included when operating the Massa TR1075D

Transducer. This feature prevents transducer damage

when altering array confi gurations whilst delivering

optimum performance. To complete the package, the

Intuitive program settings are controlled via the digital

display interface, which is housed on the front of the

19-inch rack mountable case.

To maintain our commitment to ROV survey and inspection services, SES have released a new range of high defi nition deep water sensors to operate with the fi eld proven SES Multilink digital interface. After extensive research and

testing, the new dual frequency300/600 kHz digital

side scan offers dramatically improved range

resolution, resulting in images of exceptional clarity.

The new Sub-Sea Digital Transmitter continues

this class leading theme with features parallel to

the SES Digital Transmitter featured. Developed

to supersede the industry proven SES SB5002

Transmitter, the subsea transmitter offers superior

penetration and resolution.

In addition the extensive development in

the receiver circuitry dramatically reduces ringing

and background artifacts in the data for signifi cant

advantages in shallow water sub-bottom detection.

Compatibility with various ROV telemetry systems

is achieved by fl exible power requirements and

integration via multimode fi bre, single mode fi bre

or traditional copper coax. In addition the Multilink

Software provides a complete solution for data

acquisition, post processing and reporting with

direct compatibility to external software suites such

as Coda.
