Science Objectives

This is the fifth major infrastructure deployment and servicing cruise for the Pioneer Array of the National Science Foundation’s Ocean Observatories Initiative (OOI). The Pioneer Array will include a network of moorings and autonomous robotic vehicles to monitor waters of the continental shelf and slope south of New England and, in particular, the shelfbreak front where nutrients and other properties are exchanged between the coast and the deep ocean. Data from the Pioneer Array will provide new insights into coastal ocean processes such as shelf/slope nutrient exchange, air-sea property exchange, carbon cycling, and ocean acidification that are important to the New England shelf, and to continental shelf ecosystems around the world. For further information, see http://www.oceanobservatories.org.

Science Activities

The Pioneer-5 cruise has multiple main objectives and several ancillary objectives. The main objectives can be grouped into eight categories: 1) Deploy 3 Coastal Surface Moorings (CSMs), 2) Recover 3 CSMs, 3) Deploy 5 Coastal Profiler Moorings (CPMs), 4) Recovery 5 CPMs, 5) Deploy 6 Coastal Gliders, 6) Recover 4 Coastal Gliders, 7) Deploy 2 AUV Docks and associated AUVs, 8) Perform field evaluation activities, including CTD casts with water sampling. The ancillary objectives include 1) Compare buoy and shipboard data, 2) Service 2 Coastal Surface Piercing Profilers (CSPP), 3) Conduct cross-shelf CTD surveys in the vicinity of the moored array, and 4) Conduct surveys using shipboard sensors (ADCP, thermosalinograph) in the Pioneer moored array region.

Over the Side Equipment

Will you be bringing any equipment (winches, blocks, etc.) that lowers instruments over the side? yes Details: UCONN ROV "Kraken 2 (K2) for Leg C:  Port side hydroboom will be used.  Uconn will bring their own WINCH and WIRE for this operation.

The following is a list of all major items used in support of the Kraken2 (K2) ROV:
1) Kraken2 (K2) ROV w/tool skid: 48"W x 96"L x 72"H ~ 2,300 lbs
2) ROV Control Van: 8'W x 20'L x 8‐1/2'H ~ 12,000 lbs max.
3) Oceanographic Winch: 8'W x 6‐1/2'D x 6‐1/2'H ~ 5,500 lbs
4) Hydraulic Pressure Unit (HPU): 56‐1/2"W x 41"D x 75"H ~ 1,750 lbs
5) Sheave for Umbilical: 36" diameter x 15"W
6) ROV Depressor Frame: 22"W x 45"L x 50‐1/2"H ~ 1,050 lbs
7) Deck Storage Totes (quantity 4): 43"L x 28"W x 20"H ~ stackable on deck
Power Requirements:
1) The ROV control van is wired for 208VAC Three Phase and has a maximum load of 80
Amps at 120 Volts, or 80 * 120 = 9600 VA per leg. For three legs, the total is 3 * 9600 =
28800 VA or 28.8 kVA.
The actual load under realistic conditions is typically on the order of 75A max. An
isolation transformer can be provided to accommodate 460VAC if 208 is unavailable.
The transformer is approximately 36"W x 24"D x 36"H ~ 550lbs in weight. The K2 ROV is
powered from the control van so no additional power is required for this unit.
2) The HPU is wired for 208VAC Three Phase although it can accommodate either 208VAC
Three Phase or 460VAC Three Phase power ~ whichever is readily available. In practice,
this unit is typically supported by a 100A, 208VAC Three Phase service capable of
handling the peak starting power of this unit (see below).
The three‐phase motor for the HPU is rated at 30 horsepower (HP) with an efficiency of
92.4% or 24.2 kVA with the motor running at rated load. The motor nameplate lists it as
a code letter "G" motor which would have a peak starting power is between 5.6 and
6.29 kVA per HP. Assuming an average (5.6 + 6.29) / 2 = 5.95 kVA per HP. Then, for a 30
HP motor the peak starting power is 5.95 * 30 = 178.5 kVA.
