Although the spill response, escorting docking and firefighting can be accomplished with only 5 Advanced Tugs, the maintenance requirements of these tugs create the need for the 6th Advanced Tug just to replace one of the 5 others during their substantial scheduled yearly outages. The immediate availability of the 6th Advanced Tug allows a 7.200 hp conventional tug to take skimming barge, sentinel or docking duty from an out of service tug. The ETT or SXT are classified as primary tugs to be continuously tethered to laden tankers past Seal Rocks, (Pt. Johnstone inbound), weather allowing. The SXT may be replaced by a PRT for HE duty. Conventional tugs are qualified for the limited duties described above. This is a natural monopoly situation potentially subject to RCA oversight and APSC should/must expand its surveillance, salvage, lightering, firefighting and response OSRO coverage to all regulated vessels carrying >2,500 bbl fuel and/or oil cargo, possibly in agreement with Chadux members, for the PWS COTP/Region of Operation. The ability of SERVS to garner income from other tank and non-tank vessels must be recognized as a mechanism to lower TAPS Tariff and tanker transit costs and therefore required where the additional duties would not appreciably interfere with tanker traffic and the training with additional regulated vessels would best serve both public and coop members’ interests. Other regional OSROs must similarly upgrade and capture most if not all regional response contracts because the cost of redundancy for the very large and capable working vessels needed to serve the full range of response demands in conditions so severe that they’re only bested by Antarctic waters . The state and federal responsibility for unidentified spill sources and unregulated vessels must be borne in coop fees proportionate to the volume and type of unregulated traffic to be served by that coop. Tug and barge design must match the exceptional conditions and deck operations must be automated to the point that most foreseen tasks are remote controlled from heated areas and work at the rail is only necessary to deal with emergencies.

1.5 MWe Tow Pods in auxiliary assist mode pushing on the extended skegs to supplement UL-255 and UL-1401 power for long range transport at higher speeds. The bow of the Tow Pod docks and secures to a 1.5 m steel spreader riding in a Tide Slide to provide inline thrust transfer without propeller emergence. deck crane The Tow Pod can be stored at deck level in its slide dock. The 3 m x 300 m SPI Ocean Boom can be quickly attached and remotely deployed with the Tow Pod off the transom with a winch cable. The boom and cargo net attached to the side rails automatically deploys as the boom inflates and then the aft deck cranes lower the OB ISS units into the water. All four deck cranes assist in retrieval of the boom, nets, Tow Pods and OB ISS. Cargo net & boom storage

2 m Tow Harness 5 cm x 5 cm Synthetic Mesh Net extends from the Ocean Buster to the tow harness. The mesh is attached to cables at bottom boom tension member and to an inboard cable attached to the two Tide Slides for a current and wave attenuation effect over a ~400 m² area. The Tow Pod 3000 @ 1,500 KWe front of the Ocean Buster has a thin, closely perforated air bladder capable of towing 300 m of extending the full width of the mesh to create a sheet of small air 3 m ocean boom @8 knots. The broadband data link allows programmed navigation and stabilization or manual steering via video feed. The Tow Pod docks to a Tide Slide at the vessel transom for deployment of boom from the deck level or without the boom to push on the transom or barge skeg as 3 MWe auxiliary outboard power.

The Tow Pod quickly deploys from its deck stand installed near a deployment crane. The trailing ocean boom inflates upon deployment and the remote operator navigates the pods into position and sets a cruising speed and course track for both pods and the vessel. Individual pods can be manually steered using the video feed to avoid hazards or to approach targets with precision navigation. The Delta Wing Flotation chamber provides inherent pitch and roll stability with auxiliary pitch and steering control using trim tabs.

The surfboard-shaped air chamber provides positive buoyancy and the incorporated hydrofoil forward insures rapid surface tracking when the Tow Pod dives in severe sea states. Advanced flexible propellers can develop maximum thrust at all speeds and loads

The 5 cm compressed air hose from the boom couples providing lighting & electronics power and 3 phase power & air cooling for the 1.5 MWe pod motor.

AP OSRV: 400’ X 144’ X 25’+ Z-drives with 3 drives totaling ~5.8 MWe @12 kt. Skimming in seas 15 ft it would track a wide spill sailing in a serpentine pattern or tracking sideways for a narrow slick using the forward hull to concentrate oil for the windward skimmer in the trimaran hull that protects the skimmer from wave action.

All Purpose Skimmer: Inclined Plane Skimmer with self-cleaning ice separator below excludes ice 2,500 bbl/hr creates a vacuum underneath the 56’ X 18’ X 11’ module to recover the viscous, emulsified oil and ice mixture for further separation and heating in holds

AP OSRV with CombiThrusters raised for shallow water skimming, static strategic skimming, or to generate higher current in skimming tunnels to prevent a bow wake in front of the ice accumulating ahead of the skimmer

DESMI Pollcat: Zero Relative Velocity Rope Mop Cat: 3 ZRV modules 18’ X 18’ X 14’ could replace the APS module for even faster ice free skimming that would also be wavetolerant. Turbulence in the trimaran tunnels would require generation of air bubble sheets from the tunnel bottom to stratify the oil at the surface for the rope/brush mops to

recover oil effectively.
