"Deep Down, Inc. (BULLETIN BOARD: DPDW) announced today, in a continuing effort to create installation-friendly, solution-oriented products for its clients, that it has custom-engineered, produced, and shipped BS Latcher receivers and Messenger Wire Kits to mitigate the problem of marine growth in shallow subsea environments for umbilical systems in the Shell Perdido project. The entire project included more than $1.5 million in ROV-installable subsea hardware consisting of four BS Latchers with fluid-compensated subsea protective debris covers, nine subsea blind flanges, and 13 Messenger Wire Kits, including chain jacks and drifts.
The Messenger Wire Kit includes our standard fluid-compensated debris cover, which completely surrounds the BS Latcher Receiver. This unit is connected to a new, unique, high-strength, pre-tensioned messenger wire chain that is attached to a surface hang-off device, with an upper blind flange sealing off the I-tube and holding the chain under tension with a chain stop. The chain tension and extra slack chain is handled via a surface kit. This surface kit consists of a chain locker and a new double-acting chain jacking system which is mounted on the top of the I-tube hang off device. This enables the debris cover or subsea blind flange to be held under tension or lowered to the installation vessel in a continuous and controlled process. The Messenger Wire Kit also includes cylindrical drifts with internal anodes and port holes to provide circulation and optimum corrosion protection within the I-tube."
