SAIS developed this product for Sea-Tech Services (STS)
SeaTech Services (STS) is an equipment rental company in the Oil & Gas industry sector of the Gulf of Mexico. Based in Houston Texas, STS identified a need for overhead lighting on large operations in the Oil & Gas Industry where several surface vessels are on-stie with divers, Remotely Operated Vehicles (ROVs) and cutting machinery in the water simultaneously. In light of recent events in the Gulf, STS forward-looking initiative to improve underwater safety was a timely move. Having clear vision and being in sight of every other operator while working on a busy underwater site is one of the best ways to enhance the safety of personnel, equipment and well-heads during these large-scale operations.
The solution: The SAIS SOLAS 4K Luminaire.>>>
A 390,000 Lumen output HMI lamp is housed in a custom designed quartz envelope and aluminium housing. The light will illuminate a 50ft diameter area from 50ft above using a 15in diameter reflector which was custom designed using SAIS-developed reflector-design software. The lights will be deployed in groups of three on a large pod attached to the surface by a single cable. The whole array is deployed by STS's Launch and Recovery System (LARS) which was custom built for the purpose.
The Luminaire is also suitable for use as a single light source. Other uses include film production, architectural lighting and anywhere where daylight quality illumination is needed underwater. The STS LARS is equipped with a 500ft (155m) cable but the SOLAS it is actually capable of going to a greater depth (770ft / 235m). A single light LARS will be available for rent / lease shortly. Lights are currently available for rent in the Gulf area by contacting STS directly. Rentals for film production, and other operations on the West Coast are available from SAIS.

Stone Aerospace Inc. (SAI), Ocean Research firm in Texas. ()
Stone Aeospace needed a custom aluminum housing with a 4.25in OD, and 7.5in of internal space. One end was modified to accomadate the 6in diam. dome that you see in the photo. 
The customer will be placing their own camera inside it. This one is a going to be rated for relatively shallow use (68m / 230ft) but it is actually capable of going about three times that depth (205m / 675ft). The design is based on the 1000m / 3280ft housing (see our housing flyer) and it could be modified to go that deep. The main limiting factor here is the dome.
It was pressure tested to 70m for several cycles and one long hold. November, 2008.
SeaBotix Inc. (SBX), manufacturer of remotely operated underwater vehicles (ROV). ()
Seabotix manufactures the Litte Benthic Vehicle (LBV), a small remotely operated vehicle that is capable of carrying a wide array of oceanographic tools for inspection and light duty underwater work.
The SeaBotix 1500m LBV model uses a glass viewport on the front of the vehicle that houses both of the vehicle cameras, the light source and the majority of the vehicle electronics. Several instances of glass spalling in the field led SBX to reconsider the design.
SubAqua Imaging was contracted to examine the damaged viewports and find a solution to the problem.
The glass was being damaged when the viewport was disassembled and reassembled for routine maintenance in the field. This often resulted in debris being trapped between the glass and the metal seat that it rests on. When the reassembled vehicle went to depth, the debris would cause high concentrations of stress at the glass seat leading to spalling.
SAIS redesigned the viewport to be permanently attached to the metal seats so that the vehicle could be disassembled in the field without removing the glass from its seat. One of the major design constraints was to keep all other parts the same so that the new design could be swapped out with existing ones in the field.
The redesign was completed and three complete viewports were assembled and tested by SAIS. The new design was successfully tested to SBX specified standards at their faculty.
SAIS delivered complete documentation, fixtures for building the new viewports and conducted a hand off to SBX Production at the conclusion of the project.
July 2007.
