| SINGLE_ANCHOR_LEG_MOORING | A rigid frame or tube with a buoyancy <DEVICE> at its upper end, secured at its lower end to a universal joint on a large steel or concrete base resting on the <OCEAN_FLOOR>, and at its upper end to a mooring <BUOY> by a <FLEXIBLE_RESTRAINT> (for example: a <CHAIN> or <WIRE>); single anchor leg mooring. | 12 | ||
| OIL_BARRIER_TYPE | The type of an <OIL_BARRIER>. | |||
| FLOATING | A floating tube-shaped <STRUCTURE>, with a curtain (2 metres) hanging under it, below the <WATERBODY_SURFACE>, that acts as a <BARRIER> preventing the spread of oil. | 1 | ||
| OIL_RETENTION_PIPE | A <PIPE> with <APERTURE>s from which <AIR> blows under high pressure; oil retention pipe. When the bubbles of <AIR> reach the <WATERBODY_SURFACE> they form a <BARRIER> which prevents the spread of oil. | 2 | ||
| OMNIDIR_SHIP_NOISE_CONFIDENCE | A qualitative estimate of the degree of confidence in the <<OMNIDIR_SHIP_NOISE_SPCT_PWR_LVL>> at a specified <<FREQUENCY>>, based on the quantity and variability of the measurements. | |||
| LOW | Low. | 1 | ||
| MEDIUM | Medium. | 2 | ||
| HIGH | High. | 3 | ||
| OPERATING_RESTRICTIONS_TYPE | The conditions during which the use of an <OBJECT> (for example: a <FACILITY> and/or an <AIRSPACE>) is restricted; operating restrictions type. | |||
| DAYTIME_ONLY | Daytime operations; between sunrise and sunset only. | 1 | ||
| NIGHT_TIME_ONLY | Night-time operations; between sunset and sunrise only. | 2 | ||
| NO_RESTRICTIONS | No restrictions apply. | 3 | ||
| PRONE_TO_FLOODING | Prone to flooding that may restrict normal usage. | 4 | ||
| PRONE_TO_ICE | Prone to icy weather conditions that may restrict normal usage. | 5 | ||
| PRONE_TO_SNOW | Prone to snowy weather conditions that may restrict normal usage. | 6 | ||
| SPECIAL_RESTRICTIONS | Special restrictions apply. | 7 | ||
| OPERATING_TIME | The times during which the use of an <OBJECT> (for example: a <FACILITY> and/or an <AIRSPACE>) is unrestricted; operating time. | |||
| CONTINUOUS | Continuous. | 1 | ||
| DAYTIME | Between sunrise and sunset; daytime. | 2 | ||
| NIGHT_TIME | Between sunset and sunrise; night-time. | 3 | ||
| SUMMER_TIME_APRIL_OCTOBER | Summer time; April through October. | 4 | ||
| WINTER_TIME_NOVEMBER_MARCH | Winter time; November through March. | 5 | ||
| OVERHEAD_OBSTRUCTION_TYPE | The type of an <OVERHEAD_OBSTRUCTION>. | |||
| BRIDGE_SUPERSTRUCTURE | Limited by the design of the <BRIDGE>. | 1 | ||
| HIGH_TENSION_POWERLINE | Limited by a high-tension <POWER_TRANSMISSION_LINE>. | 2 | ||
| RAILWAY_POWERLINE | Limited by a <POWER_TRANSMISSION_LINE> for a <RAILWAY>. | 3 | ||
| ROOF | Limited by the design of the <ROOF>. | 4 | ||
| VIADUCT_ARCH_CONSTRUCTION | Limited by the construction of the arch overpass of a <VIADUCT>. | 5 | ||
| VIADUCT_FRAME_CONSTRUCTION | Limited by the construction of the frame overpass of a <VIADUCT>. | 6 |
