Desired Features and Desired Alternatives Attachment J.7

1.0 GENERAL

Desirable feature and desired alternatives are provided herein for potential incorporation in the Contractor’s ship design. These features support the ship’s ability to perform its scientific mission or reduce life cycle cost. These features are highly desirable but are not mandatory.

2.0 DESIRABLE FEATURES

A. Increase Single Stateroom Quantity

Provide more than the minimum 20 single staterooms required in SOR section 640 b. The specific number of single staterooms shall be identified in the Offeror’s proposal. Twenty-four (24) single staterooms is threshold, and thirty (30) single staterooms is objective.

3.0 DESIRED ALTERNATIVE FEATURES

A. Flexible Launch and Recovery System

Section 583c Multipurpose davit system

Each small craft stowage area shall have a minimum clear deck area 10.7 m (35 ft) longitudinally and 4.6 m

(15ft) transversely. The outboard longitudinal side of the stowage areas shall be located at the deck edge. If located under structure, a clear height shall be at least 4.3m (14 ft) between the cradle and overhead structure, lighting, ventilation, and other services.

Port and starboard painter booms with traction winches shall be provided to support launch and recovery of small craft from the crewed and uncrewed stowage areas. In the stowed position painter booms shall be flush with or inboard of the skin of the ship. Painter booms shall be capable of holding the line parallel to the ship side when small craft are in the launch and recovery position. Means for safely accessing painter line leads from the weather deck shall be provided. Painter booms shall have a safe working load of at least 3,400 KG.

A launch and recovery system (LARS) that services both stowage areas on the port side and a LARS that services both stowage areas on the starboard side shall be provided. Each LARS shall be outfitted with a motion compensation system. Each small craft area shall be provided with stowage supports. Cradle supports shall be arranged to accommodate different cradle configurations and allow for cradle configuration to be changed without hot work or industrial support. Cradles shall be capable of stowing a small craft with appendages extending below the keel. The stowage cradle supports shall be separate from the structure of the LARS.

The handling systems shall be able to launch and recover crewed small craft from both the port and starboard sides simultaneously. Each handling system shall be able to launch all craft from the cradle to the water in less than 10 minutes. Handling system shall be able to recover all craft on each side of ship simultaneous in less than 10 minutes.

The handling system shall be able to accommodate any small craft that fits inside a design envelope of 9.8 m (32 ft) length by 3 m (10 ft) beam by 4 m (13.2 ft) height (keel to mast height when stowed) and a crewed craft weighing up to

6,800 KG (15,000 lbs) through Sea State 4 and recovery of craft in Sea State 5 with a reach of 3.1 m (10 ft) outboard of the ship. The system shall have dual pick points spaced 6.25 m (20.5 ft) apart with a shock absorber system and an anti-pendulation system. The aft pick point shall be between 1.68m and 1.83m (5.5 and 6ft) forward of the aft end of the Small Craft Stowage Area being served. The wire fall at each pick point shall have a dedicated winch capable of both independent and synchronized operation. A wire puller device shall be included with the LARS to maintain wire tension while spooling in and out. Launch and recovery winches shall be equipped with independent constant tension systems with a tension speed of 120 to 160 m/min. The constant tension system shall be manually engaged and automatically disengaged when hoisting is initiated. The shock absorber system shall be capable of being adjusted without industrial support to accommodate small craft weighing between 1,200 kg and 6,800 KG. The handling system shall be able to launch any stowed small craft without the need to deploy any other small craft.

A fixed control station shall be provided for the LARS with unobstructed views of the small craft stowage area being serviced. When recovering the LARS control shall automatically level off the two wire falls at 3m above the water, provide automatic slow down when the small craft passes the “at-the-rail” height, and further slowdown and automatic stop at top point to prevent two-blocking.

Launch and recovery of all vessels shall not require removal of bulwarks or lifelines.
