S3
CHARTER NEW VESSEL
Specialist Subsea Services (S3) has announced the charter of a newly-built, dynamically positioned subsea construction vessel, Neptune Larissa, from Reef Shipping through its parent group Reef Subsea. The ship will be renamed Reef Larissa. Designed with the Ulstein X-Bow, it has a faster transit speed in head seas and reduced fuel consumption. The design also provides several advantages in the foreship and on the working decks, making the vessels more environmentally and work friendly. Designed for worldwide and deepwater services, they are equipped with 150t SWL crane with active heave compensation, an enclosed ROV hangar with integrated LARS for the deployment of Work Class ROVs on both sides of the vessel, a large moonpool and 935m² of deck space . The 150t crane is able to work in over 2000m water depth and, with S3’s WROVs, the vessels will be able to operate in water depths up to 3000m.
STILL GOING STRONG
2012 will see the completion of our new marine building. This state-of-the-art facility will house:
- 35x15m Ocean Basin - 15x10m Coastal Basin - 35x0.6m Sediment Wave Flume - Marine Navigation Centre; including a full mission bridge using world-leading Transas NTPRO 5000, CAD modelling facility and ECDIS labs.

A C-Tecnics pan and tilt camera, which is almost 20 years old, has just surfaced after completing another successful season clamped to one of the piles under Swanage Pier.
Its real-time output to the internet and to screens on the pier were initially considered to be of novelty value only, but with the proven reliability of the unit and the fact that the output covers all daylight hours, the unit is now being treated as a biological monitor and “site assessment tool”.
The C-Tecnics lights were removed after the first year so as to provide genuine habitat conditions; with the low light capability of the unit dawn-till-dusk service is still provided. The camera is installed by the Isle of Purbeck Sub-Aqua Club in April each year and is expected to run, without maintenance, until its removal at the year end. Mechanically and electronically the C- Tecnics unit has undoubtedly met the requirement, but the company is still awaiting a solution to ensure the glass lens cover remains clear of marine growth.
The camera originally belonged to Dorset Wildlife Trust, who donated the unit and controls as part of their contribution along with funding from the “Dorset Biodiversity Partnership”. The harsh operational environment of the North Sea is well recognised by all equipment manufacturers, but sometimes relatively benign conditions can be more of a challenge when the operational requirement is measured in months of continuous use - rather than just a single shift ROV or diver deployment of a few hours. Retirement comes to us all and a decision has now been made to replace the unit with a portable C-Tecnics system.
