PROCEDURE FOR PROXIMITY GPS TRACKING OF TRANSECTS CARRIED OUT WITH A REMOTELY OPERATED VEHICLE ON BIOPHYSICAL SEABED PROFILING PROJECTS

Vessel Utilised: M.V. Mariko, single screw inshore/offshore fishing vessel

ROV Utilised: Seaeye Falcon ~ Serial number 1238

Clump Weight: Steel with Single Stabilising Fin at 180 pounds weight

Maximum speed of vessel whilst surveying : 1.3 knots

Minimum speed of vessel whilst surveying : .08 of a knot

Maximum Depth of Surveyed areas : 188 meters

ROV Umbilical secured to Clump Weight downline by cable ties (Zap Straps)

Clump Weight Downline marked in 3 meter increments

Location of Capstan davit for Clump Weight system, starboard side amidship / beam

This Project was carried out for the Department of Fisheries and Oceans, PBS Station Nanaimo on their Inshore Rockfish and Ling Cod Habitat Biophysical Profiling Projects

A DFO GPS System was set up on the survey vessel Mariko tied into Nobeltec Navigation software. A Clump Weight system weighing 180 pounds was utilized to maintain the ROV in close proximity to the vessels footprint as possible.

The three quarter inch braided downline rope to the clump weight was marked with pieces of string stitched through the braided rope at 3 meter increments to enable accurate positioning of the clump weight from 3 to 5 meters off seabed at all times.

Two personnel were required to run this clump weight system, one man to run the capstan winch and adjust the depth of the clump weight and one man to connect and disconnect plastic cable ties to secure the ROV umbilical to the downline. When the clump weight and ROV was to be recovered to surface the second man cut the cable ties with a side cutter tool and coiled the umbilical away from the capstan. Care was taken to ensure the umbilical never reached the capstan and only the downline was subjected to strain around the capstan winch.

Direct communications were maintained with the deck Capstan operator and the ROV Pilot.

An echo sounder monitor was positioned aft of the wheelhouse in direct view of the deck clump weight crew. A television monitor was also positioned aft of the wheelhouse in direct view of the capstan operator showing the ROV camera picture. This enabled a direct reaction from the deck crew when rock faces and obstacles were encountered by the ROV.

The ROV was flown behind the clump weight with approximately 40 feet of stray umbilical to compensate for the height of the clump weight off seabed and allow the ROV some degree of maneuverability for obstacle avoidance and movement towards items of interest, whilst underway.
The ROV umbilical was secured to the top shackle of the clump weight with nylon whipping line.

The ROV was at a seabed position below the stern of the vessels footprint flying at heights from 200mm to 500mm above seabed.

ROV Details ~

Equipment carried by the Falcon ROV included:

Twin Laser system for biophysical measurements

Depth and temperature logging device

A large Battery pack for the lasers

Total weight of additional equipment : In excess of 11 Kilos.

The Falcon ROV has a wide angle high resolution, low light, color camera with a plus or minus 90 degree movement up or down. This is a motorized Tilt system. The camera angle is shown on the ROV monitor allowing an accurate and constant camera angle to be maintained to enable laser measurements to remain constant.

The Falcon ROV also has a Tritech Sector scanning sonar of 150 meter range onboard for obstacle and seabed feature observation, a single function manipulator claw, Flux Gate Compass, Depth gauge and onboard 24 volt power supply for additional equipment.

Top speed of the Falcon ROV is 3.2 knots, maximum operating depth of the ROV is 1000 feet.

The overlay on the ROV monitor shows the following information: Depth in meters or feet, Camera angle, Time, Date, Compass heading and number of turns or twists in the umbilical.

Procedure for Survey:

A grid was established on the Nobeltec software chart for the area East offshore Gabriola Island. Random grid sections were chosen to carry out transects on. Each random grid square was to have a transect carried out across it to a distance of 500 meters, either vertically, longitudinally or diagonally.

These GPS fixed transects were recorded on the grid / chart with the Nobeltec software.

Prior to this survey, alongside a marina jetty, a control for the laser measurements was established with fixed steel and rope grids laid flat on the seabed. These grids were separated into quadrants of a known distance and the ROV was positioned both over and beside the grids at a set camera angle to ascertain the laser locations on the quadrants and ensure laser accuracy for measuring purposes during the surveys.

Once a survey grid square was chosen an initial transect was carried out on a given course heading using only the vessels echo sounder to establish the nature of the seabed on that transect in terms of cliff faces, elevations and drop offs.

This pre survey then enabled a decision to be made as to the best direction to carry out that transect with regard to risk to the ROV from collision with cliff faces whilst underway.

The vessel would then stand by at the start position of the grid square transect whilst the clump weight and ROV was deployed to seabed proximity. Once the digital video recording and GPS tracking system was started the vessel would commence the transect with the ROV maintaining camera angle and optimum depth behind the clump weight until the transect was completed.

LETTER OF REFERENCE

To Whom It May Concern 15th March 2005

Reference: The Master; Mr. A. Valentyn De Leeuw and Survey / Fishing Vessel - M.V. Mariko

SubOceanic Sciences has just completed an Inshore rock fish and ling cod biophysical Project for the Canadian Department of Fisheries and Oceans aboard the M.V. Mariko. This Project ran from the 28th of February to the 13th of March 2005, off the East Coast of Gabriola Island.

The survey entailed SubOceanic flying its Seaeye Falcon Remotely Operated Vehicle over a distance in excess of 11 kilometers of extremely craggy seabed carrying a DFO payload of nearly 12 Kilos of extra equipment being; twin lasers, large battery pack, and a depth and temperature data logger.

Our ROV flew at altitudes of sometimes only 200mm off seabed to enable identification of rock fish and habitat when light and visibility was very limited to depths of 188 meters. This was whilst the vessel was underway in ‘Live Boat’ mode with speeds averaging 1.3 knots.

The Seamanship, care and attention to detail of the Master of the Mariko was exemplary and would explain why (Despite the rugged and hazardous terrain encountered) the ROV sustained no damage from collisions resulting in nil downtime for repairs.

The Falcon ROV was flown from a clump weight system deployed off a davit arm on the starboard side of the Mariko.

Captain De Leeuw and the Vessel Mariko are an ideal combination for ROV and inshore survey Operations.

A mention should also be made of the excellent meals and ambience aboard the Mariko, the job was a pleasure from all aspects.

Sidescan Sonar and ROV Operation for The Greater Vancouver Regional District's Iona Island Deep Sea Outfall Pipelines

2005-04-27T16:35:00.000-07:00

September 2005
Greater Vancouver Regional District

The M.V. Mariko and crew was contracted to provide vessel support when SubOceanic is awarded the inspection of the Iona Island, Greater Vancouver Regional District's twin WWTP Deep Sea Outfall pipelines in 110 meters of seawater.

This contract entailed the ROV Inspection and measurement of clear openings on 200 diffusers on 2 pipelines over a 505 meter length, ROV seabed surveys of 400 meters and sidescan sonar survey of 1500 meters plus.

The M.V. Mariko provided Nobeltec GPS Tracking for several phases of the operation.

All video recording was Digital and the new Viperfish Digital Recording system with hard drive was utilised. Our Client; SubOceanic Sciences Canada Ltd, completed this Lump Sum Contract in a 3 day period, a day ahead of schedule and 2 days ahead of the previous contractor's time frame.

The Iona Outfall area is notorious for its weather exposed location, bad subsea visibility and extremely strong currents created by the Fraser River outflow.
