All-Oceans Engineering Limited and Sub-Atlantic Limited, both internationally acknowledged as leading companies in the ROV industry, have facilitated a substantial order from Subsea Resources Plc for a 6000m ROV system for the survey and recovery of valuable sunken cargo and treasure.
Sub-Atlantic's 6000m innovative Comanche ROV was selected as it perfectly met the requirements designated by Subsea Resources. It then followed that All Oceans' were the preferred partner to cover all aspects of the Launch and Recovery System (LARS) deign, manufacture and vessel integration.
All Oceans are an approved supplier of all types of umbilical handling systems and LARS to Sub-Atlantic and for Sub-Atlantic submersibles, whilst, All Oceans had worked with some of Subsea Resources' key people on deep ocean studies and equipment evaluations several years ago.
All Oceans and Subsea Resources understand the many and not insignificant issues associated with launching, recovering and supporting what is not only a substantial equipment investment but also a tool fundamental tool for realising rewarding salvage operations.
The culmination of technical knowledge and expertise of All Oceans and Sub Atlantic, has resulted in this high profile successful sale. This unique business partnership is evidence that a strategic alliance of resources can result in a competitive edge within the subsea industry. It is also evidence that companies working primarily within the oil and Gas industry can successfully succeed out with traditional target markets.

With more than 20 years experience in the detailed design of Winches and Marine Handling Equipment, All Oceans Engineering Limited have developed experience in the custom design and manufacture of a variety of Instrument cable winches. All winches are designed, built and tested in house at their facility on the outskirts of Aberdeen.
ALL OCEANS have more than a decade of experience in the design and manufacture of underwater winches and equipment. The marine market is now benefiting from this experience in that many winches are built in material combinations for no / low corrosion with dry / water lubricated bearings, sealed drives etc. Many solutions, like those shown, only need periodic visual inspection.
If not the heaviest, then certainly the tallest, design and build project undertaken by ALL OCEANS from their Aberdeen facility to date. The picture shows an "ILUC" handling system standing at its full height of 15m (50 feet)alongside the workshop.
BONUS or PENALTY?
For information, the two winches were rated to pull 8,000kg bottom wrap and handle up to 300m of 16mm steel wire rope. Level wind combined grooved drums and powered spooling.
Performance was maximised for the specified ROV hot-stab hydraulic supply and flow. Operating depth is in excess 3000msw.
FISH PEN and TANK INSPECTION SYSTEM
Oceanography Centre has commissioned the UK's first remotely
operated vehicle (ROV) dedicated to deep-ocean exploration
Capable of carrying out research down to depths of 6,500 metres the ROV will give scientists access to 98 per cent of the world's oceans.
Based at Southampton Oceanography Centre, the ROV will also be available for use by researchers from across the UK, as part of the marine science technology pool.
Professor Priede of the Department of Zoology, University of Aberdeen
said: 'This is a long overdue development that will greatly
The Tether Management System for the project is to be supplied by ALL OCEANS Engineering Limited of Aberdeen, who are obviously delighted to be involved in such a prestigious British project.
Function testing of the TMS is scheduled to take place in Aberdeen in the last quarter of 2002. 0nce complete it will be despatched for ROV and Launch and Recovery System integration and testing. The first sea trials are understood to be scheduled for the second quarter 2003.
The SOC web site has more details and information about the Project including technical specifications of some of the hardware. www.soc.soton.ac.uk/OED/ROV/index.php
The large range of various TMS building block components that ALL OCEANS have developed over the years allowed a near proven solution to be offered to the Project.
This was a major advantage when it is appreciated that what the Project called for was a TMS not much bigger, or heavier than what would normally be used with an "Inspection" class ROV, but with a load rating appropriate to a heavy "Work" class ROV.
The winch module is one of the smaller units in the All Oceans' range and will provide 260m minimum ROV excursion on the Project supplied special tether cable.
The TMS is rated for a maximum 4000kg ROV and has a proof load rating of 12,000kg but in air will weigh less than 1000kg.
A brand new
multi-purpose support vessel, the "Skandi Patagonia",
is Argentina bound with a shiny new ROV system aboard. ALL
OCEANS were contracted by the Norwegian ROV manufacturer
ARGUS Remote Systems of Bergen to supply a TMS and Launch
and Recovery System to suit their electric work class ROV.
All Oceans and Argus worked closely with the Norwegian customer to supply a fully vessel integrated system that would support the saturation diving and well work-over facilities and be a stand along ROV capability suited to the harsh environment of the South Atlantic.
The all electric and field proven
TMS option that has been available
from All Oceans for many years now
combines well to make a very capable
and compact all electric ROV package.
Also part of All Oceans supply was the umbilical winch, electro-hydraulic power pack, local and remote controls for the winch and crane, and the TMS to crane load latch. All of the equipment was designed, assembled and tested in Aberdeen at All Oceans works, prior to shipment and installation on the vessel in Norway mid November.
Acceptance trials went very well. A number of hitch free trial dives were carried out to prove the various systems before the final test of rigging a lift line to the diving bell was done. This emergency intervention capability was identified early on in the project and has an importance associated with the level of diving support capability in Argentina.
In a matter of minutes, the ROV was in the water unlatched from the TMS, had located and picked up on the crane wire and hook, then located the bell and the emergency lift sling. Then, in only two attempts it had safely hooked the bell lift sling. The 10Te bell was then cross-hauled to the vessel deck all without incident.
The ease and precision with which the operation and other manoeuvres was carried out is testament to a very capable and well designed ROV system.
