Ka`imikai-O-Kanaloa

R/V KOK The R/V KOK is a 223' single-hulled vessel owned and operated by the University of Hawaii Marine Center. The ship was modified in 1993 to serve as the primary support ship for three submersibles, but also functions as a multi-purpose oceanographic research vessel. Over 1050 sq. ft. of space is provided in 4 different laboratories and over 3000 sq. ft. of exterior working space is available on the aft main deck, the aft 01 deck, and the hangar. The KOK operates out Honolulu, Hawaii and has worked throughout the Pacific over the past 2 decades. The cruising speed is 9 kts with a minimum speed of approximately 1 kt.

Level 02 Bridge
Anybody is welcome on the bridge during daylight hours, but there's limited space and not everyone can come at once. Traffic or ongoing operations my preclude your presence. No persons will be allowed on the bridge while the vessel is arriving/departing port, piers, or maneuvering in close quarters.
Bridge
Submersible navigation center (tracking station) is located just aft of the pilothouse for easy and immediate communications with the bridge during operations. This area also serves as the ROV control station. Scientific observers are welcome to these areas during non-critical times.

Level 01

The Mezzanine runs above and along the sides of the KOK Sub-Hangar as seen in the above picture. The Mezzanine also connects to the KOK air-castle that hosts the damage control locker and CTD winch controls.

The air castle and CTD rosette boom/winch control station area provides a central location for the damage control locker. CTD' s are both deployed and retrieved from this space. Access to the Straza Tower is available here, and provisions are made for use of the gangway from this level.

Main Deck
The A-frame with telearm on the aft deck is used for launch and recovery of heavy submersible and other large, deep ocean equipment systems. Submersibles can be lifted off of the main deck, extended over the stern and lowered into the ocean. The lift controls are located on the aft deck, allowing the operator an immediate view of the submersible for optimum judgment in the execution of its deployment or recovery.

A-Frame Specs

  • Height from Deck:
  • 26 ft. (top crossbeam)
  • 25 ft. to shive/block bracket mounting points
  • Rated Capacity: 30K lbs (dynamic)
  • Width at Deck:
  • 16 ft. between inboard gunwales
  • A-frame itself is 19 ft. wide
  • Width at Crossbeam: 10.75 ft
The hangar area shelters submersibles for maintenance work while underway. The submersible is moved from the hangar to the open aft deck on a sliding cradle track system. Cradle dimensions are approx. 8.5' wide, and 12' long, and can handle loads up to 30K lbs. Designed for subs, the hanger can also be used to stage an 8'x20' container inside the high bay. Additional container slots are located on the upper weather deck as well.
  • 1330 sq. ft.

  • Can stage an 8'x20' container

The rock lab provides space for storage and analysis of solid samples recovered from the ocean. It also allows access to the 'moon pool' that houses the trolley to transport the sub control and communication equipment in and out of the water.
  • 300 sq. ft.

This lab contains the SeaBeam 2000 bathymetry acquistion system. Here It is possible to complete finished 3D, colored charts with the on board equipment.
  • 300 sq. ft.

This is the "wet" / chemistry lab on the main deck. The door in the rear leads to a small "clean room." This lab also accommodates computers for collection and analysis of CTD data. There is a cable from here to the hydro winch slip rings for this purpose.
  • 300 sq. ft.

The clean room in the back of the Wet lab. The "wet" / chemistry lab is on the main deck."
  • 150 sq. ft.

The electronics lab is for repair and development of electronic/electrical equipment associated with various scientific endeavors.
  • 200 sq. ft.

Copying and archiving of the video data to an external hard disk drives takes place here. The A/V lab is also used for storage of blank and used video data media formerly referred to as "data packages."
  • 100 sq. ft.

Conference room for science team work and meetings. This facility is useful both at sea and ashore. There is a general use computer and printer located here.
  • 250 sq. ft.



The KOK is fortunate in having two TV / Library lounges. Although small they are extremely comfortable. Smoking is not permitted in the lounges

Deep Water Multibeam Sonar System
The Seabeam 3012 Phase 1 hybrid 12 kHz multibeam sonar bathymetric mapping system is installed aboard KOK. The Seabeam is capable of acoustically charting the seafloor peaks and valleys with complete high-resolution coverage to depths of 11,000 meters. A near real-time contour plot for the current swath is produced, and the digital data is recorded for later post-processing on the ship-board Linux workstation. Some applications of this technology are: hydrographic charting for hazards to navigation, search and recovery operations, submersible support, marine resource exploration, scientific research, and locations of seamounts as natural fish aggregation devices.


CTD System
Seabird SBE 9/11plus CTD housing with pressure sensor, rated for 6,800m depth rating, equipped with:
  • 2 Sea-Bird SBE 3P temperature sensors
  • 2 Sea-Bird SBE 4C conductivity sensors
  • 2 Sea-Bird SBE 43 dissolved oxygen sensors
  • Other auxiliary sensors can be included by prior arrangement:
    • Biospherical QSP-2300 log scalar PAR sensor (2,000 m depth rating),
    • Wetlabs ECO FLNTU Chlorophyll Fluorometer & Turbidity sensor (6,000 m depth rating),
    • Seapoint SCF Chlorophyll Fluorometer (6,000 m depth rating),
    • Wetlabs C-Star 25 cm transmissometer (6,000 m depth rating),
    • Applied Microsystems SVPlus sound velocity profiler (5,000 m depth rating).
  • For casts being conducted near the sea bottom an altimeter or a 12 kHz acoustic pinger will be attached to the frame to monitor the package's height off the sea floor.
  • Water samples can be collected with 12 L PVC sampling bottles with internal Teflon-coated springs. The bottles can be triggered at any depth with a Seabird SBE 32 carousel.
  • 24-bottle and 12-bottle rosette frames are available.
