It's Your Ship - Management Techniques from the Best Damn Ship in the Navy

   My story might be called "The Education of USS Benfold" which is a guided missile destroyer that I commanded for twenty months beginning in June 1997. Commissioned in 1996 for duty in the Pacific Fleet, the ship is a beautiful fighting machine: 8,300 tons of armor protecting the Navy's most advanced arsenal of computerized missiles; a radar system that can track a bird-size object from fifty miles away; a highly skilled crew of 310 men and women; and four gas turbine engines capable of driving the ship to thirty-one knots—nearly thirty-five miles an hour—as it speeds into combat, shooting up a huge rooster-tail backwash. To be given this spectacular vessel as my first sea command was thrilling, but also ironic. Opportunity had called, but in a troubled industry. Our military has spent a lot of time and money preparing for tomorrow's battles with antiquated methods. We continue to invest in the latest technologies and systems, but, as we all know, technology is nothing but a facilitator. The people operating the equipment are who give us the fighting edge, and we seem to have lost our way when it comes to helping them grow. The statistics are startling. In recent years, nearly 40 percent, or almost 80,000, of the 200,000 people who join the military annually, won't complete their enlistment contract. Although most will leave the service involuntarily, doing so is not a reflection of their character. Of those who do complete their first hitch, a very small percentage will reenlist —not nearly enough to keep our senior billets filled. Worse yet, the best talents are often the first to leave. Since it takes $35,000 to recruit a trainee and tens of thousands more in additional training costs to get new personnel to the basic level of proficiency, the cost of this attrition to the taxpayer is staggering. And that cost is only the beginning, since the dropouts go home and counter-recruit against us, making it even harder to convince others to join.

Mine Warfare Vessels of the Royal Navy 1908 to Date

   For many decades the navigable waters of the world have been traversed by ships of all nations in peace and in war. and during the peace ships have foundered by stress of storm far loo often. With the commencement of war. the hazards of the sea are increased many times by reason of the weapon known as the sea mine, or mine. The evolution of the mine is dealt with briefly later in this chapter, but despite the swept channels, the seas are still dangerous today from mines that have been laid by ships of many nations. In the early 20th century the British Admiralty decided that the threat from the weapon of the weaker power, for such was the mine described, was now loo well known and foreseen on too large a scale to be ignored. Consequently, in 1908 the Board decided that a number of the smaller vessels of the Fleet such as ships of the "Alarm", "Dryad" and "Sharpshooter" classes should be converted into minesweepers. From information gained by the trials and experimentation with the purchased trawler Oropesa II and its minesweeping gear, additional trawlers were purchased from commercial owners. The other need was in the provision of minelayers; here, the Royal Navy has always depended on requisitioned vessels to a large extent, although a number of classes of minelayers have originated from Admiralty designs and conversions of existing ships of the Fleet...

WWII US Landing Craft In Action

   The Landing Craft, Vehicle Personnel was called the most important weapon to come out of World War Two. This was due to its ability to land troops and equipment on an enemy shore, withdraw, reload, and return numerous times to resupply the beachhead. The LCVP was a development of the earlier LCV and LCP and was also designed by Andrew Jackson Higgins of New Orleans, Louisiana. The LCVP was constructed entirely of wood, with the exception of the steel bow ramp. This craft was 35 feet 9 inches in overall length, with a maximum beam of 10 feet 6 inches. Its draft was rated at 3 feet 5 inches forward when fully loaded and 2 feet 2 inches forward when light. The LCVP displaced 15,000 pounds lightly loaded, 18,500 pounds at hoisting weight, and 26,600 pounds fully loaded. Either a sling or davits on the parent ship could hoist the LCVP. It had a maximum speed of 12 knots light and nine knots fully loaded. Power was provided by a 225 HP Gray Marine 64HN9 six-cylinder diesel engine. The range on 180 gallons of onboard fuel was 110 nautical miles at full power and full load. A few LCVPs were powered by 250 HP Hall-Scott gasoline engines and were primarily used for training. The LCVP normally carried a crew of three: a coxswain, a mechanic , and a crew hand. The latter two were also responsible for manning the .30 caliber M1919 machine guns when they were fitted. The gunners sat in cockpits situated just forward of the splashboard on the aft deck. The LCVP's cargo well was 17 feet 3 inches in length and 7 feet 10 inches at maximum width, with an interior height of 5 feet. The bow ramp was operated by wire cables attached to an electric winch located on either side of the aft interior hull. The starboard side bulkhead contained the emergency tiller and a ramp equalizing sheave and cable guard. The exterior hull sides were fitted with .2 inch Special Treatment Steel armor protection for the crew, troops, and cargo.

German Cruisers of World War Two In Action

   The cruisers that fought in World War Two descended from sail-powered frigates. These vessels were designed for long-range independent operation to gain information about the movement of an enemy's fleet, to raid an enemy's commerce, or to track down and defeat an enemy's commerce raiders. This led to the famous frigate vs. frigate duels of the American Revolution and the War of 1812, in which the advantage generally went to the Americans. This was due to the stouter construction and slightly larger guns of their frigates, including USS CONSTITUTION, better known as "Old Ironsides". Generally, a successful cruiser was a ship possessing high endurance and enough speed to outrun anything bigger, enough power to defeat anything its own size. It also had enough protection to survive encounters with any number of smaller units without disabling damage. Meeting this set of requirements with steam-powered metal ships was far more difficult than with wind-powered wooden ships. High-speed from a steam engine can only be achieved at the expense of range. Unlike sail powered ships, whose range was limited only by the amount of food and water carried for its crew, steam-powered warships consumed coal or oil at rates directly related to the ship's speed. The more armor and armament a ship carried, the more fuel it took to achieve a particular speed. Even at most economical consumption rates, a cruiser-sized ship could never achieve the independence of operation synonymous with the frigates they replaced, without the ability to refuel at regular intervals. This led to the development of networks of coaling stations in all the places a navy might expect to operate and points in between. Colonial expansion before the advent of steam had concentrated on sources of wealth, including the gold of South America and the spices of India and the East Indies. Now parts of the world that had previously been of little interest - including the coast of Africa and Pacific islands - became the objects of intense competition between expansionist colonial powers. This competition led directly to World War One.

Recommendations for Oil Tanker Manifolds and Associated Equipment

   The present fourth edition of this OCIMF publication (first published in several decades ago, in 1971 and subsequently revised three times) in order to reflect the industry developments. This release edition does not contain any significant changes to the content of the document relating to the cargo/bunker manifolds as well as any associated equipment on board. However, the authors of this volume have added a completely new Annex to the main body of the paper, willing to take into consideration the technical requirements that are there in a number of terminals and applicable to the tankers to transfer the cargo vapors to the shore-located facilities. We would also like to underline the fact that those recommendations have been provided with the sole intention to provide the required regulatory guidance to the  operators of the vessels trading to the terminals where the installation of the vapor collection systems is mandatory. The recommendations are supplementing the IMO-developed uniform safety design standards that are applicable to the shipboard marine vapor recovery systems as well as the USCG-issued regulations addressing the same matter. They shall only be treated as relating to the uniform manifold arrangements and shall not be considered applicable in any other cases.

clean seas guide for oil tankers
   The present Guide was prepared and released in accordance with the relevant technical requirements of the MARPOL Conventions and associated interpretations with the intention to be used together with them. Please note however that this paper is not dealing with the requirements related to the construction/equipment. Under the Annex I of the Convention any discharge of oil or oil-containing mixture is prohibited from the oil tankers,  including the mixtures coming from the bilges located in the cargo pump rooms, within a distance of fifty nautical miles from the nearest land. In addition, the flow and concentration, as well as the quantity of the substances discharges anywhere else are also limited. Obviously, the only way to ensure due compliance with these limitations is to adhere to the oil retention procedures. Those procedures would typically involve the collection and separation of any oily waters appearing as a result of tank cleaning/ballasting operations. These mixtures are to be accumulated in a special tanks to be subsequently disposed of somewhere ashore. This volume is mainly concerned with these procedures and their application; the information contained in this document will be of great importance and practical use to the crew members as well as to all other personnel involved in the above stated operations.

mooring equipment guidelines
   The technical guidelines that are contained in this publication released by OCIMF, are intended to represent the mooring technology and practice proven most effective. However, it should be taken into consideration as necessary that the information that is provided in the pages of the this volume may not be practical enough to retrofit literally all possible aspects of this technique to all existing systems. The attempt as been made by the authors of this volume to unify, significantly update, and refine the existing mooring guidelines while adding some essential information which has been poorly defines or even omitted before. The authors have exercised remarkable care ensuring the optimization of the design performance of all the associated mooring equipment and arrangements. At the same time, we can see that they have really done their very best to avoid the overlooking such important factors as the ease of handling and also the safety of the involved personnel. As a result, this book represents a recommended minimum of the associated requirements and it will definitely be quite useful to both ship designers and marine surveyors, plus terminal and ship operators. For sure, they are not to inhibit the future innovations of the relevant technological advances in any way...

Guide to Purchasing High Modulus Synthetic Fibre Mooring Lines

   The intention which has declared by the authors of the present technical document was to give the necessary professional guidance to all people directly involved in the ordering of the HMSF, standing for the high modulus synthetic fiber mooring lines, including the lines that are fabricated from Aramid, LCO and HMPE fibers. The aim is to ensure the due understanding of the particular mechanical properties of these mooring lines, encouraging the processes of adoption of improved technical specifications and quality assurance. We would like to underline that the recognized international standards are there for the construction of the HMPE lines; however, the standards relating to Aramid and LCP fibers are limited. That is the main reason why the information contained in the present publication would definitely be of great practical use to people considering various ordering options. The MHSF lines are considered as a good alternative to the traditional mooring lines that are usually made of the steel wires, due to their mechanical properties, particularly strength-to-weight, as well as the other advantages, for example the ease of handling. After several years of nearly incident-free use of the HMSF lines, the shipping industry has experiences a number of failures, particularly on large LNG carriers...

Guidance for the Prevention of Rollover in LNG Ships
   This guidance was produced by SIGTTO to members' concerns about the some of the interpretations of the functional requirements for emergency shutdown systems; in particular, differences between the needs of the liquid natural gases industry and those of liquid petroleum gases industry. It was also aimed to encourage and promote the use of linked emergency shutdown systems at both LPG and LNG terminals, especially where cargo transfer rates are quite high or where they handle one of the cargoes stated in IGC Code 1993/Chapter 17. However, this SIGTTO publication is not intended to contradict any international or national requirements or standards for operational practices at the liquefied gas ship-shore interface. One of the primary objectives of this guidance was to advise the operators/owners of gas carriers about the rollover-related issues. The rollover itself mainly refers to the quick release if the LNG vapor occurring when the layers of different densities of LNG are spontaneously mixed in a cargo or storage tank. While for the conventional onshore terminals all such issues are known and understood, for LNG vessels the associated circumstances are a bit unusual and have to be paid serious additional attention...

A Justification into the Use of Insulation Flanges at the Ship-Shore and Ship-Ship Interface

   The purpose of the present SIGTTO publication is to provide a proper explanation of how insulation flanges protect from ignition caused by arcing. It contains information on the inductive circuits, electrical characteristics of the cargo transfer hoses together with the supporting calculations, some examples of the effects of hose inductance and resistance, information on the effect of capacitance, testing of the flanges and multiple loading arms and parallel circuits, all supplemented with the list of definitions and conclusions and recommendations. The insulation flanges have been used for several decades; their effectiveness is sometimes seriously challenged, though there have been no reported fire incidents on the manifolds installed on board of tankers or gas carriers. This shall be taken into consideration by the ship operators having a background of road tanker operations, supplying the LNG as fuel oil. Since this document mainly concentrates on the protection from arcing-caused fires, we would definitely consider it very important and recommended to everyone involved in such sort of operations as the info provided in the booklet might help in improving the operational safety.

LNG and LPG Experience Matrix

   This LNG/LPG Officer Experience Matrix is aimed to offer the transparent guidance for proper assessment of the risks relating to the officer complement. It considers a number of elements, including experience in rank, length of sea service, training assessment and experience in LNG/PLG operations. When evaluating risk in the event of non-compliance with a particular element of the experience matrix, consideration should be given to other mitigating factors, including bespoke training, the manning scale in place, time with the LNG/LPG ship owner/operator the wider competence management systems employed by the ship operator in officer recruitment and development. In the meantime, it is very important to appreciate that subject matrix has been supplied to serve as a tool for the risk evaluation and management. When dealing with the risk evaluation in case of non-compliance with the specific element of this matrix, due consideration is to be given to other mitigating factors involved, such as the manning scale, bespoke training and others. Careful attention to management of the risks has been widely recognized of the maintenance of the safety record of the ship and environment protection.

Report on the Effects of Fire on LNG Carrier Containment Systems

   Current LNG transportation practice provides for pressure relief systems, designed with credit for the tank's insulation in order to to prevent gas cargo pressurization due to boil-off and fire, as per IMO IGC Code 8.5. However, it is uncertain to what extent any insulation degradation, in a fire situation, is taken into account in the design of PRV systems. As foam plastic insulation materials are subject to possible melting, degradation and/or ignition at temperatures lower than might be achieved during such fire exposure, there is concern that the PRV systems may not be capable of relieving the vapor flows that would result from the increased boil-off due to partial or total insulation failure. This SIGTTO publication covers following matters - the origins of the IGC Code, fire scenarios, LNG carrier pressure relief systems, simplified reapplication of the Code for loss of insulation, heat transfer into the tank; time based heat transfer, response of insulation materials to heat, and others. This is quite useful document providing necessary updates required to be taken into account to organize the transportation, storage and handling of the LNG cargoes in a safe way.

LNG Transfer Arms and Manifold Draining, Purging and Disconnection Procedure

   The first introductory part of this SIGTTO-released document says that it has been written following numerous reports from the members of the present international organization, on the confusion and misunderstanding noticed between some ship and jetty operators; that is main reason why it has been released and please note that this document mainly pertains to terminals where rigid transfer arms are employed. The principal objective of this report was to disconnect the arms in such a way that would totally eliminate the possible risks of release of the liquid and, in addition, reduce the release of the cargo vapor to the environment to a practically achievable minimum. In order to safely and timely conduct this operation, it is critically important that a good and carefully thought out procedure has been established and that the communication between people on board and on shore is reliable and permanent, since both of them carry the responsibility for safety during subject operation. Among the most important aspects covered within this report there are drain system, isolation of valves, liquid removal, purging flammable vapors, verification, disconnection of the cargo manifolds etc. The annexes at the end provide case studies and example procedures...

A Contingency Planning and Crew Response Guide for Gas Carriers Damage at Sea and in Port Approaches

   The present Guide would mostly be applicable to all liquid gas carriers both at sea and approaches to the ports; it has been released by the working group with the assistance from members of OCIMF, ICS, SIGTTO and ISU aiming to provide a thorough reference that would be useful to the operating managements of gas ships in reviewing or developing their contingency planning. The contingency plans supplement the SOPEP required for all ships >400 GT as per the Annex I to MARPOL. Regardless of how the liquefied gas is carried (pressure/temperature being meant), the cargo containment shall not be treated as part of the vessel's structure. Such containments are in all cases located inboard of the vessel's side plus above the bottom. The big portion of this booklet has been taken from the CPD (contingency planning document) that have been formulated by the managing teams of a number of companies within the shipping industry. The present guide is mainly addressed at the ship operating companies  and assumes some general understanding of the cargo characteristics as well as of the design, construction and, of course, operation of the gas carrying ships. Definitely useful publication not only to the managerial stuff but also all personnel.

A Guide to Contingency Planning for the Gas Carrier Alongside and within Port Limits

   The main purpose of the present guide is to provide a thorough reference which might be useful to various port authorities as well as operating management of LNG carriers and terminals in reviewing or developing their planning in order to avoid the accidents or at lease reduce their possibility. The publication would also be quite helpful in controlling the possible consequences of such accidents happening within the port limits. This second (revised) edition takes into account the STCW Convention and SOLAS IX as well as the ISM Code. It covers ships in transit and operation, ships alongside, public relations and periodic review. Note, however, that the present publication shall not be treated as a comprehensive technical manual on contingency planning since the authors have confined this document to the aspect directly relating to the carriage and handling of gases. The circumstances influencing the contingency planning may vary from port to ports in the matters such as nautical/weather considerations, types of cargo being handled, authorities etc. When preparing this document, broader interpretation of the term "contingency planning" was taken, including considerations related to the accident prevention and control of possible consequences.

Guide to Planning Gas Trials for LNG Vessels

   The present document is mainly intended to provide all members of the Organization with the guidelines of the requirements that are applicable to the testing the LNG cargo handling systems. The scope of the publication shall be considered applicable to the designs featuring established membranes, SPB and spherical tanks. Note that the content shall not be extended to the prototypes and novel ship designs since they will most probably require some specific approach, for example additional testing. Moreover, this paper shall not be treated as a sort of operational procedures; it is rather an aid to preparation of a specification to be used during the gas trials. The authors have tried to address all items that have to be tested before the vessel is handed-over as well as the testing done after the delivery, at the time of loading of the first cargo. The figures there in the text of the document are indicative and it would be better to refer to the shipbuilder's/manufacturer's recommendations for figures for the particular ship. It is assumed that the trials are done by the shipbuilder before delivery, which is actually the common practice. The trials themselves are conducted to confirm the correct operation of the handling systems...
