Art Anderson Associates completed design of a new dredge vessel for Pacifica, a Seattle-based vehicle assembler. The 50-foot vessel was  delivered to a customer for gold dredging operations in the coastal waters of Alaska near Nome.

Our naval architects and marine engineers were engaged in December, 2011 to develop the dredge design concept in to a complete design for construction. In the first phase, we developed a computer-based model of the vessel based on the concept drawings, and employed the model as the basis for initial hydrostatic and weight calculations. In Phase II, we developed construction drawings for the hull and superstructure, and finalized the weight and stability calculations. In the project’s final phase, the team provided fuel, water and controls drawings and design support. The vessel was designed specifically to meet the unique requirements of sub-surface dredging operations in the remote coastal waters of the Bering Sea, and is powered by twin 300HP Yamaha outboards. It features a custom-designed bow for cutting through the rough seas and all pump, sluice and crane systems to conduct its gold dredging mission.

The project was delivered on time and under budget.

In response to increased growth in the region, King County constructed a new $1.6-billion regional wastewater treatment plant, called Brightwater. The facility serves portions of King and Snohomish counties and supports the County's mission to protect public health and the environment. The new facilities will include a treatment plant, conveyance (pipes and pumps taking wastewater to and from the plant), and a marine outfall and will feature the largest membrane bioreactor system in the United States.

Art Anderson Associates provided civil and structural engineering services to develop a marine outfall for King County's new Brightwater wastewater treatment system. Our scope included the preparation of plans, specifications, a basis of design report and calculations for plastic pipe weights and a reinforced concrete pipe anchor in support of our design/build partner Triton Marine Construction. We also designed the temporary construction trestle. The purpose of the anchor is to resist axial loads on the twin 63-inch HDPE pipe system caused by seismic or landslide events. Both of the mile-long pipes and the anchor system are now resting 600 feet below the surface of Puget Sound.

The Brightwater Outfall project was featured in the September 28, 2008 issue of Engineering News Record. Engineering News Record recognized the Brightwater Outfall project with the "Best of the Best" award in the heavy/civil construction category. Engineering News Record also awarded the project its "Best of 2009" Award in the heavy/civil category.

Art Anderson Associates provided naval architecture and marine engineering services for the conversion of the Ex-USNS AGATE PASS (YTT-12), a former torpedo test craft, into a NOAA research vessel. The converted vessel, now named the NANCY FOSTER, was outfitted to conduct coastal research along the US Atlantic and Gulf coasts. Our services were performed as a series of conversion tasks under our IDIQ contract with NOAA for naval architecture and marine engineering services. These tasks include engineering design for:

  • De-militarization of the ship by removing all torpedo systems, including ejection tanks, handling and firing equipment, void tanks, torpedo hold support structures and high-pressure compressed air system.
  • Installation of shell closure plate to close off torpedo tunnel openings, watertight bulkheads in the torpedo hold to create multi-use spaces, inclined ladder access and equipment access hatches to the new spaces.
  • Installation of new watertight flats to create a new stores space and exercise/MSD room.
  • Installation of a new watertight door and inclined ladder to create an auxiliary machinery room with a main deck enclosure structure.
  • Modification of bilge/ballast and fuel oil piping to convert ballast tanks to fuel oil storage.
  • Installation of a new 5.7 m SOLAS rescue boat, davit, and associated equipment

  • Installation of a new A-frame (SWL 20,000 pounds) with a constant-tension winch and associated equipment
  • Installation of a new man-rated aft knuckle boom crane (SWL, at 40 foot reach, 10,000 pounds).
  • Replacement of main deck edge railings with a bulwark and installation of portable lifelines and deck edge rubber rub rail, except in way of A-frame and J-frame openings.
  • Installation of a new marine sanitation device and related sewage piping modifications.
  • Installation of a new walk-in refrigerator/freezer.
  • Installation of a new double-plate, spade rudder and new steering gear equipment.
  • Stability assessment, revision of damaged stability calculations and new trim and stability booklet.

NANCY FOSTER's mission includes the characterization of various habitats in NOAA's National Marine Sanctuaries, pollution assessments and studies to improve understanding of the connection between marine habitats and estuaries. These missions support scientific data collection through bottom fish trawling, sediment sampling, side-scan sonar and multi-beam surveying, sub-bottom profiling, core sampling, diving with air and NITROX, ROV operations, and servicing oceanographic/atmospheric surface and subsurface buoys. The vessel employs state-of-the-art navigation and propulsion systems that result in high quality and efficient data collection.

Art Anderson Associates led the development of a business plan to provide high-speed passenger-only ferry service from Bellingham to Friday Harbor. The Whatcom Council of Governments, in partnership with the Port of Bellingham and the Port of Friday Harbor envision the ferry service as a critical commercial link between the two thriving communities. The plan builds on the results of a demonstration service, which operated in the winter months of 2005-2006.

The business plan encompassed all aspects of the prospective service, addressing its viability, operations and impact on the local economy. Art Anderson Associates utilized its proprietary FerryPro™ software to develop an operational model and pro-forma financial statements. Our ridership and financial analyses established the baseline for service scheduling, pricing and compensation for the contracted operator.

An economic impact model was developed by our subconsultant, the Western Washington University Small Business Development Center, and we examined the economic "ripple effect" of the infusion of new jobs and the resultant commerce from the new connection between the cities. We also analyzed the cost of alternative travel, both in financial (ticket and travel cost) and environmental terms (greenhouse gas emissions). The result of our efforts is a firm foundation on which a successful service can be further developed, built and operated.

Art Anderson Associates provided construction management services under a term contract with the US General Services Administration, Region 10 for the $20 million seismic upgrade/rehabilitation of the historic 57,000-sq. ft. Pioneer Courthouse in Portland, Oregon. Art Anderson Associates' Project Representative facilitated resolutions and served as the point-of-contact for all owner design and construction issues. We also performed site reviews and managed the owner's construction budget and all special inspector contracts required.

The project entailed replacement of the building foundation with a state-of-the-art base isolation system to preserve the historic 1897 structure during a seismic event. The friction pendulum isolators, used for the first time in the Portland area, isolate the building from the earth, allowing it to move freely in an earthquake.

Rehabilitation work included preservation and reconditioning of historic features, including light fixtures, intricate plaster work, woodwork, wood flooring and office fireplaces. All mechanical, electrical, data/communication and security systems were replaced. Exterior improvements included sidewalk, entry steps and stone wall restoration. The basement level was lowered and a secure parking area for federal judges provided. Mechanical/Electrical system startup/commissioning was included in our task order.

The project has received a number of awards for construction and design excellence. Some of these awards include:

Art Anderson Associates is engaged in a project to survey lifesaving equipment throughout the fleet of Alaska Marine Highway System (AMHS) ferries and recommend an upgrade strategy. The project goal is improving the safety of passengers and crew members through evaluations of the effectiveness of the current lifesaving equipment, exploring alternative strategies and scenarios, and preparing the work packages (plans, specifications, and cost estimates) for modification of the vessels.

Systems surveyed include structural, electrical, and hydraulic systems; lifeboats, davits, and cradles; service/work boats, davits, and cradles; means of rescue equipment; and life rafts. Mr. Marty McKay, Art Anderson Associates' Project Manager, conducted nine shipchecks to evaluate the condition of the existing equipment, which was documented in the project's Design Study Report. These shipchecks included a detailed walkthrough of the vessel to document equipment conditions with notes and photographs, and interviewing ship's personnel to understand the challenges they face in the operation of the equipment.

One of the challenges encountered included the difficulty of training crew, particularly relief crews, on the nuances of equipment that is different from ship to ship. Other challenges include maintaining an adequate spare parts inventory, maintaining the condition of the equipment, and obtaining necessary service and parts for continued operation. It was quickly identified that standardizing the equipment fleet-wide, as much as possible, will assist in meeting these challenges. The prioritization of US sources for equipment was also a means to alleviate these concerns, due to more cost-effective service, availability of spare parts, and improved responsiveness compared with foreign sources.

Upon completion of the surveys, an extensive review of applicable regulatory requirements for lifesaving equipment was conducted, and included SOLAS and CFR regulations. Three primary strategies were developed and analyzed for cost-effectiveness, including refurbishing existing equipment, replacing existing with a fleet-wide standard in kind, and aligning equipment with regulations and standardizing fleet-wide as much as practicable.

All documentation of the condition of equipment, identification of alternatives, and the associated cost estimates were submitted in the final Design Study Report. Current efforts involve developing the work packages for the modifications and obtaining necessary ABS approval.

Art Anderson Associates is the lead naval architect/marine engineer developing the design of a Portable Floating Fish Collector (PFFC) for operations in the Cougar Reservoir in Oregon. The purpose of this device is to gather additional information on juvenile fish movement in Willamette Valley Project reservoirs, representing a cost-effective means of safely obtaining juvenile fish for research and monitoring. The PFFC is designed to be modular, able to be disassembled for roadway transport to other reservoirs, and generates an attraction flow that can be varied from 20-140 cfs. The anchoring system accommodates up to a 200-foot variation in reservoir water level, including rapid fluctuations. Using a series of winches, the anchoring is designed to allow the PFFC orientation to be changed. The anchors are easily-retrieved for redeployment. Power is provided by a subsurface cable to shore, which also carries operational and instrumentation reading data.

The role of Art Anderson Associates on the project includes preparation of a bid-ready construction package for project elements that include complete structural design of the PFFC vessel (except the fish collection module), mooring system, and subsea cable. Our services also included developing a marine operations plan for deployment, recovery, and disassembly of the PFFC, and deployment and retrieval plans for the anchoring and mooring system.

Under the US Department of Homeland Security's Assistance to Firefighters Grant Program, the Tacoma Fire Department received $750,000 to refit the city's fireboat COMMENCEMENT. Art Anderson Associates teamed with BMT Nigel Gee of the United Kingdom to provide engineering design and consultation for the renovation and refit of the vessel.

The first phase of the project involved a comprehensive trade-off study that examined and balanced the needs and specifications of the Tacoma Fire Department and the budgetary constraints of the DHS grant. Art Anderson Associates examined the operational and financial practicality of proposed upgrades and modifications and will provide recommendations to the department.

Art Anderson Associates provided structural; propulsion; pumping, hydraulic and electrical system; and command and control modification engineering and design. Included with this design package was a detailed cost estimate and construction schedule. Art Anderson Associates also served as the Fire Department's representative in the bid and construction phase, negotiating between the owner and contractor, resolving engineering problems and maintaining weight control data.

COMMENCEMENT is one of two fireboats operating in the Tacoma Fire Department. The vessel was built in 1982 by Vosper Hovermarine as a multipurpose fiberglass surface effect ship (SES). The vessel has two 445bhp marine diesel engines powering two 19-inch propellers and a 285bhp marine diesel engine that provides power to six 24-inch aluminum alloy fans, which, when engaged, maintain an air cushion beneath the vessel. This cushion allows the COMMENCEMENT to achieve speeds of up to 30 knots and maintain a stable ride in choppy seas. Since 1983, the vessel has provided fire suppression, search and rescue, evacuation, hazardous materials response and emergency medical service for the city. The COMMENCEMENT's service area includes the Port of Tacoma, the sixth-largest container port in the United States.
