A ship for transporting cargo gas, such as natural gas, includes a ship structure and a middle transverse bulkhead constructed by gas storage containers. Each gas storage container includes an enclosure and a pipe coil within the enclosure that contains the cargo gas and it is the enclosures of the gas storage containers that are integrated into the ship structure to form the middle transverse bulk head.

A channel member is adapted for mounting on a watercraft with a foot component slidable along the channel. A latch component is mounted on the foot component by a tongue extending through a slot between a base part of the foot component and a footrest part. The latch also has a tooth to engage with openings in the channel for adjustment of the position of the footrest. A handle portion of the latch component can be flexed to free the tooth from a channel opening, whereupon the foot component can be slid to a desired position and the handle released to lock the foot component in the adjusted position. The footrest can have differently contoured sides for engagement by a foot of a user, and the three foot brace parts (the channel, foot component, and latch component) can be manually separated and reassembled with the either of the contoured sides facing the user.

Electronic Warfare (EW) systems Human Machine Interface (HMI) is used to classify and correlate electronic emissions. The HMI must maximize operator efficiency and support effective decision making and must create a workspace that reduces the operator?s manual interaction with the system. In order to capture the HMI requirements, SEA CORP will follow a structured process to study the AN/BLQ-10 operator workflow and capture the results in an HMI Concept of Operations (CONOPS). SEA CORP successfully employed this process, based on interaction with fleet personnel and subject matter experts, in defining new HMI concepts for the AN/BYG-1 Weapon Control System (WCS) Strike Displays. This effort will define a display framework, based on the CONOPS, which will decrease the number of menus, controls and windows, providing the operator more intuitive operations. The displays will be designed to support a touch screen user interface in accordance with the SWFTS HMI common style guide. SEA CORP will utilize the existing EW Server API/ toolkit to obtain the organic and non-organic datasets and create a display widget library that will support a highly extensible system. As a result, the HMI architecture design will facilitate easy integration and future growth of the EW HMI.

Technological advances have facilitated weapons systems capable of simultaneously supporting multiple missions leading to cost efficiencies and greater operational flexibility. Future systems capable of deploying multiple payloads from a single missile will enable various targets to be attacked with a single launch allowing more efficient use of limited and valuable resources. For such a system to work as anticipated, positive control and equipment safety of the weapons multiple payloads is critical. SEA CORP proposes the use of commercial off the shelf (COTS) automotive air bag inflators as the energetics source to release and impulse the payload from its stowed position. Inflators feature high power density, small volume, high reliability, a broad manufacturing base, clean gas output, and strict quality standards making them ideal, cost-effective candidates for applications requiring minimally-sized, power-efficient energetics packages. SEA CORP has successfully adapted inflators to launch and restrain weapons and other projectiles and to perform mechanical work and can effectively tune the inflators to conform to minimal exit velocities and maximum acceleration forces. This ensures equipment safety and effectiveness. SEA CORP only works with inflator vendors with impeccable quality and safety records and uses a different type of device than those subject to recent industry recalls.

A method and system for ballast water treatment is provided for a vessel with a ballast water tank system that pumps water from a local environment through a conduit into at least one tank on the vessel. The water contains aerobic micro-organisms from the local environment. Oxygen-containing gas is introduced into the water as it is pumped through the conduit. Living organisms are added into the water with the oxygen-containing gas introduced therein. As a result, the tank receives a mixture of the water with the oxygen-containing gas introduced therein and the living organisms added thereto. The living organisms are selected to consume (i) the aerobic micro-organisms, (ii) oxygen dissolved in the water, and (iii) food sources for the aerobic micro-organisms contained in the water. A vacuum is applied to the tanks ullage space at a point in time after the mixture is received in the tank.

Present sonobuoys allow for the selection of functions such as RF Channel, Depth, etc. by use of a single selector button and LED display along with a second button used for verification located on the side of the sonobuoy. Selection or verification requires access to the buttons and cannot be accomplished once the sonobuoy is loaded into the launcher. The capability to select and verify functions wirelessly employing either an in-launcher Ir interface or a battery-operated, Ir handheld device useable in low light conditions that can interface to a standard personal computer (PC) has been deemed desirable for adaptation to the P-8A Poseidon by NAVAIR. Use in P-8A would permit programming and verification to be accomplished via direct interface with the mission computer while the sonobuoy is in the launcher and while the aircraft is in flight. Team SEA CORP will advance Remote Electronic Function Select (REFS) Ir sonobuoy programming technologies developed in Phases I and II to TRL-6 to enable future P-8A integration. The Team SEA CORP solution will address specific requirements for P-8A integration. The full system will cost under $15K in production. Reliability and the ability to operate in various environments will be addressed.

Missiles, use electro-explosive devices (EEDs) to perform mulitple functions during operation. This effort seeks ways to improve on the EED"s reliability and lower the failure or inadvertent activation rate of these devices. During Phase I, SEA CORP investigated replacing EEDs with commercial off the shelf (COTS) automotive airbag inflators to perform the required pneumatic functions of various devices. The Phase II effort will develop, build, and test selected inflator based prototype devices for the most promising applications. Approved for Public Release 14-MDA-7903 (2 July 14)

This effort to improve the capabilities of the ESM system will increase the reliability and reduce lifecycle support costs of the Radar Wideband (RWB) subsystem on submarines. Analog to digital converter (A/D) based digital receivers will be applied to yield improvements in Radar signal acquisition and processing. In-phase and Quadrature (I/Q) data streams will be created from which intra pulse modulations may be derived. Improvements for intercept and characterization will include: shorter and longer pulse width processing, signals with dynamic pulse repetition intervals, signals with frequency agility, and solid state transmitters. This will allow the Electronic Warfare systems the capability to meet the challenges brought about by the emergence of complex Continuous Wave (CW) solid state radars that threaten the stealth and secure operations of the submarine force. This will improve the submarine mission readiness and effectiveness.

Since the advent of impulse launching various payloads from Navy and other military combatants, the source of the impulse energy has been either an explosive gas generator (propellant) or stored high pressure gas in a flask. Both of these methods have high maintenance and/or clean-up costs and are typically limited to one type or size of payload per launcher device. This limits operational flexibility and increases logistical complexity and cost. SEA CORP has developed a family of impulse launchers that use COTS automotive air bag inflators that significantly expands the capability and flexibility of any single launcher design to employ a number of payloads. The inflators, widely used in the automotive industry, are small cylinders containing a highly compressed inert gas that is released when a small initiator is electrically actuated. By changing the number, size, and initiation timing of the inflators, the launcher can be adjusted to accommodate various payloads that have different impulse requirements. The technology was originally developed under a NAVSEA SBIR to launch light weight torpedoes up to 740lbs from surface ships. In the proposed application, SEA CORP will adapt the technology to provide the impulse energy to eject missiles from submerged submarines.
