Gallons Gallons Gallons RHINO Ferries 2500 10 25 RHINO Tugs 250 10 25 Causeway Tugs 100 5 10 Warping Tugs 100 5 10 (b) Refueling will be accomplished as directed by the Ferry Control from LST's, Tankers, LBO's and Army Class III Beach Dumps. Water will be supplies from LST's, LBW's and Army Beach facilities. Obtain fuel and water in the following order. First, at ship being unloaded; secondly, at oil barge or water barge; in emergency at Army Beach Dump. Empty Gasoline and Lubricant cans will be unloaded on the beach. Empty water cans will be returned in exchange for full cans. Care will be exercised to keep from polluting water cans. (c) Bad Weather. When the weather is too bad for unloading and when pontoon craft are not required for work, they will proceed in accordance with instructions of the Ferry Control to the lee provided by the Gooseberries and secure to the Corncobs. (d) Defects. All officers and coxswains in charge of pontoon equipment will report defects to the Ferry Control Officer who will arrange with the RHINO Repair Barge or the Maintenance Officer for the necessary repairs. (2) RHINO Ferries. (a) Description - The RHINO Ferry is a self-propelled pontoon barge (6x30), (41' wide - 176' long) designed for the transportation of equipment and general cargo. It has 18" empty and 42" loaded draft and has a net capacity of 300 tons. They are particularly adapted for unloading vehicular equipment from ships onto shallow beaches. (b) Instructions - The RHINO Ferries are assigned to Task Force "O" and "U" for towing from the marshaling areas to the Far Shore Beaches. They are an integral part of the Ferry Service and will operate under the above Task Forces during the Assault Phase and under the NOIC's of the two beaches after the assault phase. COMLANCRAB11thPHIB Order No. 29, dated 29 March 1944, Standard Operating Procedure for Towing and Marrying RHINO Ferries will govern. (c) For Beach "O", the towing LST's will lift only the first operating crews, who will at the prescribed time be disembarked at the destination onto the RHINO Ferries and RHINO Tugs. They will then proceed and report to the Ferry Control for duty. During the tows, a minimum crew from the first crew will ride on each RHINO Ferry and Tug. The relief crews will be lifted by the "BERNARD CARTER" and delivered at the destination on D / 1. The relief crews will be disembarked and placed aboard the RHF and RHT in accordance with instructions from the Ferry Control. The first crews at that time will proceed to the accommodation ship in accordance with arrangements previously made by the Ferry Control. (d) For Beach "U", the towing LST's will lift both the first and relief operating crews, at the same time. During the tow, a minimum crew fro the relief crew will ride on each RHINO Ferry and Tug. At the destination and at the prescribed time, the first crew will disembark onto the RHINO Ferries and Tugs. They will then proceed and report to the Ferry Control for duty. The relief crew will at the same time be picked up by LCI's or the accommodation ship for housing until they are needed for relief of the first crew. (3) Causeways and Tugs. (a) Description - There will be 4 sunken causeways, 2 at each beach with 8 blisters each. Each causeway will be made up of 14 (2x30) (14' wide, 176' long, 5' high) sections making a total length of 2450 feet. The blisters are (4x12) sunken stages, staggered on alternate sides. The spacing shall be that required to get about 2 1/2 feet difference in elevation between stages. That will be about 250 feet staggered or 500 feet between stages on each side. At each beach, the causeways will be placed one at a time, placing will begin on the first high tide. The Army has tentatively established coordinates for the causeway as follows: #1Alt. 666906 Beach "O" No. 1 672903 No. 2 691895 #2Alt.687893 Beach "U" No. 3 430000 No. 4 453967 #4Alt.420010 (b) Uses of Causeway. 1. The causeway is designed to permit LCT Mk.4, and Mk.6 and RHINO Ferries to discharge unwaterproofed vehicles at any state of tide. 2. The time during which any one "blister" can be used varies, of course, with the beach slope and range of the tide, but ample time for discharging one LCT or RHF may be expected under the worse conditions. In many cases, it should be possible to work several craft during the available period of one blister and at times two blisters may be worked together. (c) Instructions for Operation of Causeway. 1. Each causeway will have three tugs to assist LCT in berthing and unberthing. When instructed to berth, the LCT should "bring to" one cable from the seaward end of the causeway. Two tugs will then come off and make fast alongside. 2. A causeway pilot will board the LCT and assist the C.O. in berthing and controlling the tugs as required. 3. No kedge will be used, but the LCT should run a headline onto the "blister" as soon as possible, the tugs holding her in position as necessary, under the direction of the pilot. 4. As soon as vehicles have disembarked and the ramp is hoisted, the LCT is maneuvered away from the causeway by the tugs. Tugs should let go as soon as the craft is well clear of the causeway and the LCT should turn outwards away from the causeway in order to avoid the next craft approaching. (d) Limitations due to weather. The limiting weather conditions are dictated by the capabilities of the pontoon ugs which assist LCT to berth and unberth. A cross wind of force 3 to 4 and a cross set of 1 knot at the same time may be taken as a limit with a reasonable factor of safety. In exceptional circumstances, these conditions could no doubt be exceeded. (e) Signals. The following signals are to be employed: 1. FLAG P (International) by LCT. - "Ready for Tugs". Note: (To be hoisted by each LCT as she approaches causeway and is ready to berth. P is to be made by shaded lamp at night.) 2. FLAG C (International) by LCT. - "Intend to berth". Note: (C to be made by shaded lamp at night.) 3. GREEN HAND FLAG (Green light at night) will be shown from the causeway in position at which LCT is to berth. 4. RED HAND FLAG (Red light at night) will be shown form the causeway to indicate: "Do not berth, remain off causeway." 5. FLAG V (International) by LCT. "Require additional tug or other assistance." (4) Warping Tugs (12). The warping tugs consist of a pontoon barge with a 9000-lb. Anchor, a two drum hoist with 1000 feet 1 1/8 inch steel anchor cable forward and a 1000 feet 1 1/8 steel pulling cable aft and two inboard propulsion units. They are designed for pulling broached boats, etc. off the beach. There are 12 in number and distributed as follows: Beach "O" Beach "U" Mulberry 2 0 Recovery and Repair 4 2 Causeway 2 2 These warping tubs are manned with Seabee operators, and they operate under the control of the activity to which they are assigned. (5) RHINO Repair Barges (2) The RHINO Repair Barge consists of a (6x24) pontoon barge with two 5-ton cranes and a tool house. It is designed for work in repairing pontoon equipment and replacing their motors. There are two in number; one at each beach. They will operate under the Salvage and Repair Officer with Civil Engineer Officers in direct charge. (6) Drydocks. The drydocks consist of two large pontoon docks, one on each beach. They are designed for repairing surface craft up to and including the LCT class. They will operate under the Salvage and Repair Officer with Civil Engineer Officer in direct charge. f. Captured Ports (DREW) The first three captured ports are expected to include one major and two one-half minor DREW units. Task Unit 127.2.2.6 (28 NCB) is assigned these projects and will stage from Base II. g. P.O.L. Task Unit 127.2.2.4 (146th NCB), a Seabee Battalion of 23 officers and 521 men especially trained in the industry has been set up for the construction, maintenance and operation of the Navy POL installation on the Far Shore. The battalion is based at Plymouth where the POL units are assembled and packaged for quick installation on the Far Shore.
