USNS Salvor

Disabled or stranded ships might require various types of assistance before retraction or towing can be attempted. In her 21,000 cubic feet (590 m³) salvage holds, Salvor carries transportable cutting and welding equipment, hydraulic and electric power sources, and de-watering gear. Salvor also has salvage and machine shops, and hull repair materials to effect temporary hull repairs on stranded or otherwise damaged ships.[4][5]

Salvor and other ships towed the grounded USS Port Royal off a reef near Pearl Harbor, Hawaii in February 2009.[7]

Stranded vessels can be retracted from a beach or reef by the use of Salvor's towing machine and propulsion. Additional retraction force can be applied to a stranded vessel through the use of up to six legs of beach gear, consisting of 6,000-pound (2,700 kg) STATO anchors, wire rope, chain, and salvage buoys. In a typical configuration, two legs of beach gear are rigged on board Salvor, and up to four legs of beach are rigged to the stranded vessel.[8]

In addition to the standard legs of beach gear, Salvor carries four spring buoys. The spring buoys are carried beneath the port and starboard bridge wings and are painted bright orange.[9] Each spring buoy weighs approximately 3,100 pounds (1,400 kg), is 10 feet (3.0 m) long and 6 feet (1.8 m) in diameter, provides a net buoyancy of 7½ tons, and can withstand 125 tons of pull-through force.[8] The spring buoys are used with beach gear legs rigged from a stranded vessel when deep water is found seaward of the stranded vessel.

Salvor's propulsion machinery provides a bollard pull (towing force at zero speed and full power) of 68 tons.[28][29]

The centerpiece of Salvor's towing capability is an Almon A. Johnson Series 322 double-drum automatic towing machine. Each drum carries 3,000 feet (910 m) of 2 ¹⁄₄-inch-diameter (57 mm) drawn galvanized, 6X37 right-hand lay, wire-rope towing hawsers, with closed zinc-poured sockets on the bitter end. The towing machine uses a system to automatically pay-in and pay-out the towing hawser to maintain a constant strain.[28][29]

The automatic towing machine also includes a Series 400 traction winch that can be used with synthetic line towing hawsers up to 14 inches in circumference. The winch has automatic payout but only manual recovery.[28][29]

The Salvor's caprail is curved to fairlead and prevent chafing of the towing hawser. It includes two vertical stern rollers to tend the towing hawser directly aft and two Norman pin rollers to prevent the towing hawser from sweeping forward of the beam at the point of tow. The stern rollers and Norman pins are raised hydraulically and can withstand a lateral force of 50,000 pounds (23,000 kg) at mid barrel.[28]

Two tow bows provide a safe working area on the fantail during towing operations.[28]

Salvor has several diving systems to support different types of operations. Divers descend to diving depth on a diving stage that is lowered by one of two powered davits.

The diving locker is equipped with a double-lock hyperbaric chamber that can be used for recompression after deep dives or for the treatment of divers suffering from decompression sickness.[24]

The MK21 MOD1 diving system supports manned diving to depths of 190 feet (58 m) on surfaced-supplied air. A fly-away mixed gas system can be used to enable the support of diving to a maximum depth of 300 feet (91 m).[24]

The MK20 MOD0 diving system allows-surface supplied diving to a depth of 60 feet (18 m) with lighter equipment.[24]

Salvor carries SCUBA equipment for dives that require greater mobility than is possible in tethered diving.[24]

Naval mine laying and recovery.[10][21][22]

In addition to her two main ground tackle anchors (6,000-pound (2,700 kg) Navy standard stockless or 8,000-pound (3,600 kg) balanced-fluke anchors) Salvor can use equipment associated with her beach gear to lay a multi-point open water moor to station herself for diving and ROV operations.[5]

A typical four-point-moor consists of an X pattern with four Stato Anchors at the outside corners and Salvor at the center, made fast to a spring buoy for the close end of each mooring leg with synthetic mooring lines. Using her capstans, Salvor can shorten or lengthen the mooring line for each leg and change her position within the moor.[30]

As built, Salvor had a 7.5-ton capacity boom on a forward kingpost. However, the kingpost and boom were removed and replaced by a 10,000-pound deck crane in 2011.[31] She has 40-ton capacity boom on her aft kingpost.[24][29][32]

Salvor has heavy lift system that consists of large bow and stern rollers, deck machinery, and tackle. The rollers serve as low-friction fairlead for the wire rope or chain used for the lift. The tackle and deck machinery provide up to 75 tons of hauling for each lift. The two bow rollers can be used together with linear hydraulic pullers to achieve a dynamic lift of 150 tons. The stern rollers can be used with the automatic towing machine to provide a dynamic lift of 150 tons. All four rollers can be used together for a dynamic lift of 300 tons[24] or a static tidal lift of 350 tons.[33]

Salvor also has two auxiliary bow rollers, which can support of 75 ton lift when used together.[24]

Salvor has three manually operated fire monitors, one on the forward signal bridge, one on the aft signal bridge, and one on the forecastle, that can deliver up to 1000 gallons per minute of seawater or aqueous film forming foam (AFFF).[24] When originally built, Salvor had a fourth remotely controlled fire monitor mounted on her forward kingpost,[4] but this was later removed. Salvor has a 3600-gallon foam tank.[29]

In addition to the equipment carried by Salvor, the US Navy Supervisor of Salvage maintains a stock of additional emergency fly-away salvage equipment that can be deployed aboard the salvage ships to support a wide variety of rescue and salvage operations.[34][35]

Salvor departed Sturgeon Bay, Wisconsin on her first voyage on 25 July 1986. She visited Sault Ste Marie, Michigan, before conducting diving operations for certification in Lake Superior. During the first part of August she made stops in Toronto, Quebec, and Halifax. After departing Halifax, she was diverted to New York City because of Hurricane Charlie. She arrived at Little Creek, Virginia and 21 August 1986 and received her ammunition loadout. Her next stop was Charleston, South Carolina, where she took a single navy harbor tug (ex-Hyannis) in tow.[4]

Salvor arrived at Beaumont, Texas, on 4 September where she had to wait out Hurricane Danielle for several days before she was able to get underway and take three additional vessels, two World War II vintage auxiliary tugs (ex-Navigator and ex-Tunica), and an auxiliary fleet tug (ex-Tenino), in tow at the mouth of the Sabine River. From there, Salvor towed the four vessels in a "Christmas tree" rig to the Christobol, Panama, arriving on 21 September. Salvor transited the canal, and re-rigged her tows again in Rodman, Panama and departed for San Diego, California on 26 September. After a brief stop at San Diego, Salvor continued with the four towed vessels, and arrived at her home port of Pearl Harbor for the first time on 1 November.[4]

Salvor spent the remainder of 1986 in or around Pearl Harbor, conducting training, validations, and trials.[4]

After holiday upkeep, Salvor began 1987 with an underway shakedown cruise. During the shakedown cruise, Salvor and USS Reclaimer collided during tow and be towed exercises.

Salvor returned to Pearl Harbor to first to onload parts for Conquest and later with USS Conquest in tow, after a collision between Conquest and Barbour County. After more delays because of casualties aboard Conquest, Salvor departed Pearl Harbor again on 26 September 1987. After a fuel stop at Kwajaelein, Salvor arrived at Subic Bay, Philippines, on 16 October 1987.[10]

Salvor visited Hong Kong and returned to Subic Bay where she took two floating drydock sections (AFDB-1 and AFDB-2E) in tow. On 25 November she fueled at sea from USS Mauna Kea.
