077 HUMAN ENGINEERING AND SYSTEM SAFETY

077.1 Human Engineering

ASTM F1166 specific criteria shall be applied in the design of compartments, spaces, work and control stations, and facilities. Factors affecting both normal and emergency conditions, such as illumination and environmental conditions, shall be as outlined in ASTM F1337. Vessel systems shall be designed to be operated by a range of the specific user population, bounded between the 5th-percentile female to the 95th-percentile male. Operation, maintenance and repair activities and procedures shall minimize manual handling, and shall be designed to be conducted by this range of individual physical capability.

077.2 System Safety

Safety guards shall be installed over unprotected moving parts of rotating or oscillating equipment and machinery that could pose a hazard to personnel. Guards shall also be installed over moving wire ropes that could be contacted by personnel. Guards for scientific winches shall not enclose the drums or cable lead.


078 MATERIALS

The vessel shall be constructed of best commercial marine grade materials and components. Where CRES is used, it shall be Class 316, passivated.

Cast iron shall not be used in any service where it is exposed to impact loading.

Dissimilar metals that are not electrolytically compatible shall not be joined directly. Electrolytic corrosion shall be prevented by insulating dissimilar metals from each other with gaskets, washers and sleeves, or bushings of insulating materials. Faying surfaces between wood, metals and laminates, or any combination of these materials, except machinery foundation shims, shall be protected by use of bedding compound plus one coat of primer applied to the metal. Faying surfaces between wood and other materials shall be protected by use of wood preservative fortified bedding compound. Use of explosion bonded bimetallic joint material is preferred for aluminum-to-steel joints.

Asbestos, ceramic fiber, radioactive or radium-bearing material, magnesium, cadmium plated parts, chromate or lead containing materials, and mercury shall not be used in construction applications where a functionally equivalent substitute is available.

The use of polychlorinated biphenyl (PCB) or materials identified by Occupational Safety and Health Administration (OSHA), International Agency for Research on Cancer (IARC) monographs, and National Toxicology Program (NTP) annual report as carcinogenic or potentially carcinogenic materials is prohibited.

All materials used in applications exposed to the weather, located in bilges, or used in ballast tanks shall be suitable for the corrosive seawater environment.

079 STABILITY

The stability calculations shall address the following loading conditions:

Full load condition with fuel required for endurance, 100% fresh water and 100% consumables.

Mid-voyage condition with 50% fuel, 50% fresh water and 50% consumables. Arrival condition with 10% fuel, 10% fresh water and 10% consumables. Capacity load condition with full fuel tanks, full fresh water tanks and full

consumables.

All loading conditions, except capacity load, shall include service life weight allowance and service life KG allowance. All loading conditions shall include full scientific load. Trim in the full load condition shall not exceed one foot by the stern. A maximum trim of one-half foot by the bow is acceptable, provided the Contractor can demonstrate by model tests that the vessel is directionally stable and fully supports ship and scientific operations in this condition. List in the full load condition shall not exceed 1/2 degree to port or starboard.


Permanent ballast shall not be used. Ballasting of fuel tanks is not acceptable. Variable water ballast shall not be used in the full load condition.

Equipment and machinery shall be arranged and installed to facilitate access for use and access for purposes of maintenance, adjustment or repair. Access to equipment shall permit ease of maintenance and operation and shall permit the movement and positioning of portable tools and test and support equipment required to perform the maintenance and operational tasks. Permanent fittings and structure shall be kept clear of routes required for the removal of machinery, whenever possible.

Bolted equipment removal plates (BERPs) or welded equipment removal plates (WERPs) shall be provided for removal of large equipment and components where the size of the item or component to be shipped or unshipped exceeds door or hatch sizes. Removal of the BERPs or WERPs shall not require the removal of other fixed vessel structure. Ancillary systems shall be kept clear of BERP or WERP openings. The selection of a BERP or WERP shall be based on the regularity of need for equipment removal. Where equipment can be expected to require removal every eight years or less, a BERP shall be used for removal. For longer periods, a WERP is acceptable. As a minimum, a BERP shall be provided in the engine room.

Access shall be provided for maintenance and replacement of propulsion motor bearings.

Monorails, padeyes and lifting fittings shall be provided and attached to adequate structure, to permit equipment and machinery removals and installations.

Washers, dryers, hot water heaters and other domestic equipment shall be capable of being removed from the vessel without dismantling the equipment or the joiner work or do
