nautical queries HITTINGTETTTT DECK Q. a. In addition to sufficient air tankage to float a lifeboat when filled with water and open to the sea, what quantity of air tankage is required for each person permitted in the boat? b. How are air tanks of lifeboats tested? A. a. One cubic foot per person. b. Each air tank shall be fitted with a standard 4-inch pipe-size testing nipple with hexagonal cap. Cap to be of corrosion resistant material. The tank must withstand a test pressure of one pound per square inch. Pressure of 1 pound per square inch may be applied by using a pneumatic pump with a gage, or by blowing into the nipple directly or through a rubber tube, or simply exposing the tank to a hot sun whereby the air in the tank is expanded. After a suitable interval if the pressure is maintained as would be indicated by the air escaping from the nipple after the cap is removed, the tank has no leak. Leaks would equalize the pressure in the tank with that of the atmosphere. Where leakage exists, the exact location may be determined by using soapy water brushed over the suspected area while pressure over atmosphere is put on the tank, or by immersing the suspected area in water and watching for bubbles. Q. On vessels fitted with power ventilation, where may the switches be found for shutting off the ventilation in the event of an emergency such as a fire? A. All electrical ventilation systems shall be provided with remote control means for stopping the motors in case of fire or other emergency. For the machinery space ventilation, there shall be provided a control located in the passageway leading to, but outside of, the space. For all other ventilation systems, a control station shall be located in the fire control room or wheelhouse, if continuously manned both when underway and when at dock, or in an accessible position in the passageway leading to, but outside of, the space ventilated. These emergency control push button stations shall be protected by installing glass doors on which there will be marked: "In case of fire break glass and push button to stop ventilation." Q. Why is the exhaust temperature inherently lower on a two-cycle Diesel engine than on a four-cycle Diesel engine? A. The exhaust temperature is lower on the two-cycle engine than the four-cycle engine because the scavenging air of the two-cycle engine cools off the exhaust gases. Q. Describe the usual method of igniting the fuel in semidiesel or lowcompression diesel engines. A. Ignition in a semidiesel or lowcompression diesel is usually caused by the fuel being sprayed against an uncooled portion of the combustion space. This uncooled portion is generally a hot bulb or plate and requires preheating from an outside source such as an electric plug or a blowtorch upon first starting the engine. Q. What is the most significant difference between the Diesel and Otto cycle engine? A. The most significant difference between the Diesel and Otto cycle engines is the method used for the ignition of the fuel. In the Diesel cycle, ignition takes place automatically by the heat of the compressed gases, whereas in the Otto cycle an outside source of heat is required to ignite the fuel charge. Q. Will poor combustion have any pronounced effect upon the lower working parts of the engine, namely the bearings, crank boxes, connecting rod bearings? A. In the trunk piston-type of engine all substances of a carbonaceous nature escaping by the piston find their way to the crankcase. They become mixed with the lubricating oil and if not removed, may prevent correct lubrication of the bearings. Removal from the crankcase of such carbonaceous substances is not always possible by filtration or centrifuging. Filters or centrifuges may have ample capacity to remove such substances but the oil in circulation does not always pick them up. Evidence of the truth of this statement can be found in the form of black mucky deposits coating the interior surfaces of the crankcase. If they become removed and are entrained in the oil, they may overtax the capacity of the filters or centrifuge. Excessive contamination of the lubricating oil shortens its life. The operator is tempted to use oil after it is no longer in fit condition to enter the bearing. For the reason mentioned and a number of others, the bearings and other working parts within the crankcase are likely to suffer as a result of poor combustion and its effect upon lubrication. thermore, the lowered mechanical efficiency of the engine reacts directly upon the bearings in the form of an overload. It frequently results in an excessive rate of wear. Conditions such as these may be traced to the fuel pump or spray nozzles. To avoid them the fuel injection system should receive careful attention. Fur AMENDMENTS TO REGULATIONS [EDITOR'S NOTE.-The following regulations have been promulgated or amended since the last issue of the PROCEEDINGS. A complete text of the regulations may be found in the Federal Register indicated at the end of each article. Copies of the Federal Register containing the material referred to may be obtained from the Superintendent of Documents, Government Printing Office, Washington, D.C., 20402.] TITLE 46 CHANGES SUSPENSION AND REVOCATION PROCEDURES REGULATIONS AMENDED TO REFLECT STATUTORY INTERPRETATIONS By Commandant action of October 30, 1964, certain provisions of the regulations governing Marine Investigations and Suspension and Revocation Proceedings have been amended. The sections affected are: 46 CFR 137.01-1(a) (1), 137.01-30 (a) (3), 137.01-40(a) and 137.05-20 (b). The purpose of the amendments to 46 CFR 137.01-30 (a) (3), 137.01-40 (a), and 137.05-20 (b) is to amend the wording to conform to the jurisdictional limitations in subsection 239 (g) in Title 46, U.S. Code, while the amendment to 46 CFR 137.01-1(a) identifies what laws and regulations are included in the reference "title 52 of the Revised Statutes or of any of the regulations issued thereunder." These amendments constitute a statutory interpretation. 1. Section 137.01-1(a) is amended by adding a new subparagraph (1) reading as follows: § 137.01-1 Authority for regulations. (a) * * * (1) Where the provisions in Title 46, U.S. Code, section 239, or other laws or regulations contain a reference to "title 52 of the Revised Statutes or of any of the regulations issued thereunder," or one similar to it, it is deemed to be a general reference to the applicable provisions in Title 46, U.S. Code, sections 170, 214, 215, 222, 224, 224a, 226, 228, 229, 230234, 239, 240, 361, 362, 364, 372, 375, 391, 391a, 392, 393, 399, 400, 402-414, 416, 435, 436, 451-453, 460, 461, 462, 467, 470-482, and 489-498, and the regulations issued thereunder, which are in this chapter. (See F.R. November 5, 1964, for the text of the other sections referred to.) TITLE 33 CHANGES LARGER COAST GUARD CUTTERS EXEMPTED FROM CERTAIN NAVIGATIONAL LIGHTING RULES Larger Coast Guard vessels of special construction cannot comply with certain applicable statutory requirements relating to the lights required to be displayed by public and private vessels when navigating on the high seas or navigable waters of the United States, its territories or possessions, without seriously affecting the characteristics and functions of the vessels concerned. Changes in antennas on WPG and WAVP class Coast Guard Cutters required the relocation of masthead lights. The planned employment of these ships is such that it is not practical to modify the design to meet the requirements for vertical separation of range lights and minimum height of forward masthead lights without seriously compromising other important vessel characteristics. Except for special-constructionlighting-exemptions Coast Guard vessels are in full compliance with the other provisions of the applicable International Rules or Inland Rules governing the areas where the vessels will be operated. 33 CFR Section 135.40 has been amended and 33 CFR 135.45 has been added to give public notice as to character and position of the navigational lights on these exempted vessels. These vessels, ranging in length from 255' to 327', operate to the greater degree on the high seas. (See F.R. of November 5, 1964, for the text of these changes.)
